NEW QUESTION # 23
Which two statements about VXLAN VNIs are correct? (Choose two.)

• A. VNIs identify a collision domain.
• B. VNIs identify a broadcast domain
• C. VNIs can have over 16 million unique values.
• D. VNIs are alphanumeric values.

Answer: B,C

Explanation:
VXLAN VNIs are virtual network identifiers that are used to identify and isolate Layer 2 segments in the overlay network. VXLAN VNIs have the following characteristics:
* VNIs can have over 16 million unique values. This is because VXLAN VNIs are 24-bit fields that can range from 4096 to 16777214, according to the VXLAN standard1. This allows VXLAN to support a large number of Layer 2 segments and tenants in the network.
* VNIs identify a broadcast domain. This is because VXLAN VNIs are used to group the end hosts that belong to the same Layer 2 segment and can communicate with each other using VXLAN tunnels. The VXLAN tunnels are established using the VTEP information that is distributed by EVPN. The VTEPs are VXLAN tunnel endpoints that perform the VXLAN encapsulation and decapsulation. The VXLAN tunnels preserve the Layer 2 semantics and support the broadcast, unknown unicast, and multicast traffic within the same VNI2.
The following two statements are incorrect in this scenario:
* VNIs identify a collision domain. This is not true, because VXLAN VNIs do not identify a collision domain, which is a network segment where data packets can collide with each other. VXLAN VNIs identify a broadcast domain, which is a network segment where broadcast traffic can reach all the devices. Collision domains are not relevant in VXLAN networks, because VXLAN uses MAC-in-UDP encapsulation and IP routing to transport the Layer 2 frames over the Layer 3 network1.
* VNIs are alphanumeric values. This is not true, because VXLAN VNIs are numeric values, not alphanumeric values. VXLAN VNIs are 24-bit fields that can range from 4096 to 16777214, according to the VXLAN standard1. Alphanumeric values are values that contain both letters and numbers, such as ABC123 or 1A2B3C.

NEW QUESTION # 24
When editing a device configuration to install some manual changes, which procedure should be followed?

• A. Edit the configuration on the device directly by the CLI; the changes will automatically be adjusted in the Juniper Apstra configuration
• B. Delete the device from the Juniper Apstra system, change the configuration, then re-import the device.
• C. Edit the pristine configuration of the device.
• D. Add a persistent change to a device configuration with a configlet.

Answer: D

Explanation:
A configlet is a small piece of configuration that can be applied to a device or a group of devices to make persistent changes that are not overwritten by Apstra. Configlets can be used to install manual changes that are not part of the Apstra rendered configuration, such as custom commands, scripts, or features. Configlets can be created, edited, and deleted from the Apstra GUI or CLI12. References:
* Configlets Overview
* Configlets User Guide

NEW QUESTION # 25
You want to apply a configlet to a specific device using Juniper Apstra. Which two parameters would be used to accomplish this task? (Choose two.)

• A. port group
• B. hostname
• C. form factor
• D. tags

Answer: B,D

Explanation:
To apply a configlet to a specific device using Juniper Apstra, you need to specify the device's hostname and tags. The hostname is the unique identifier of the device in the Apstra system, and the tags are the labels that you can assign to the device to group it with other devices that share the same characteristics. You can use the hostname and tags to filter the devices that you want to apply the configlet to in the blueprint catalog12.

NEW QUESTION # 26
Multilenancy for applications is achieved by creating virtual networks (VNs) within which construct?

• A. security policy
• B. routing table
• C. routing zone
• D. connectivity template

Answer: C

Explanation:
According to the Juniper documentation1, a routing zone is an L3 domain, the unit of tenancy in multi-tenant networks. You create routing zones for tenants to isolate their IP traffic from one another, thus enabling tenants to re-use IP subnets. In addition to being in its own VRF, each routing zone can be assigned its own DHCP relay server and external system connections. You can create one or more virtual networks within a routing zone, which means a tenant can stretch its L2 applications across multiple racks within its routing zone. Therefore, the correct answer is D. routing zone. A routing zone is the construct within which you create virtual networks to achieve multitenancy for applications. References: Routing Zones

NEW QUESTION # 27
In the Juniper Apstra Ul. you are creating a VNI pool for virtual networks.
In this scenario, which VNI range is acceptable?

• A. Any range is acceptable for the VNI pool.
• B. The valid VNI range is 1 through 10000.
• C. The valid VNI range is 2 through 4096.
• D. The valid VNI range is 4096 through 16777214.

Answer: D

Explanation:
In the Juniper Apstra UI, you can create VNI pools for virtual networks that use VXLAN encapsulation in the overlay network. A VNI pool is a resource pool that contains a range of VNIs that can be assigned to the virtual networks. The valid VNI range for a VNI pool is 4096 through 16777214, according to the VXLAN standard1. Therefore, the statement B is correct in this scenario.
The following three statements are incorrect in this scenario:
* Any range is acceptable for the VNI pool. This is not true, because the VNI range has a lower and upper limit defined by the VXLAN standard1. The lower limit is 4096, and the upper limit is 16777214. Any VNI outside this range is invalid and cannot be used for VXLAN encapsulation.
* The valid VNI range is 2 through 4096. This is not true, because the VNI range does not start from 2, but from 4096. The VNIs from 2 to 4095 are reserved and cannot be used for VXLAN encapsulation1.
* The valid VNI range is 1 through 10000. This is not true, because the VNI range does not include 1, which is also reserved and cannot be used for VXLAN encapsulation1. The VNI range also does not end at 10000, but at 16777214, which is the maximum possible value for a 24-bit VNI field1.

NEW QUESTION # 28
Which two statements are correct regarding a pristine configuration in Juniper Apstra? (Choose two.)

• A. It is the device's previously active configuration.
• B. It Is the configuration file on a device before acknowledgment in Apstra.
• C. It is the device's currently active configuration.
• D. It is the configuration file placed on the device when decommissioning the device.

Answer: B,D

Explanation:
A pristine configuration in Juniper Apstra is the configuration file that is used to onboard a device into the Apstra software application. A pristine configuration contains the minimum settings that are required for the device to communicate with the Apstra server, such as the hostname, management IP address, username, password, and SSH key1. A pristine configuration has the following characteristics:
* It is the configuration file placed on the device when decommissioning the device. This is because when a device is decommissioned from the Apstra software application, it is reverted back to its pristine configuration, which removes all the network configuration and services that were applied by the Apstra software application. This allows the device to be reused or repurposed for another network2.
* It is the configuration file on a device before acknowledgment in Apstra. This is because when a device is onboarded into the Apstra software application, it is initially in the discovery state, which means that
* the device is discovered by the Apstra server, but not yet acknowledged by the user. In the discovery state, thedevice has the pristine configuration, which can be viewed and edited by the user. Once the user acknowledges the device, the device moves to the deployed state, which means that the device is ready to receive the network configuration and services from the Apstra software application3.
The following two statements are incorrect in this scenario:
* It is the device's currently active configuration. This is not true, because the pristine configuration is not the device's currently active configuration, unless the device is in the discovery state or the decommissioned state. In the deployed state, the device's currently active configuration is the network configuration and services that are applied by the Apstra software application, which are based on the blueprint and the intent3.
* It is the device's previously active configuration. This is not true, because the pristine configuration is not the device's previously active configuration, unless the device is in the decommissioned state. In the discovery state, the pristine configuration is the device's initial configuration, which may or may not be the same as the device's previous configuration before being onboarded into the Apstra software application. In the deployed state, the device's previously active configuration is the network configuration and services that were applied by the Apstra software application before the last commit3.

NEW QUESTION # 29
IBA probes analyze telemetry data from specified devices within a blueprint. Which component Identities devices that supply data tor a specific probe?

• A. graph query
• B. processor
• C. search engine
• D. data selector

Answer: A

Explanation:
A graph query is a component that identifies devices that supply data for a specific probe. A graph query is an expression that matches nodes in the Apstra graph database based on their attributes, such as device name, role, type, or tag. A graph query can be used to select the source devices for the input processors of a probe, as well as to filter the data by device attributes in the subsequent processors of a probe12. References:

NEW QUESTION # 30
You have recently committed a change after creating a new blueprint in Juniper Apstra. In the main dashboard, you see a number of anomalies related to BGR What is a likely cause of these anomalies?

• A. The fabric has not converged yet.
• B. Spine-leaf links are incorrectly set.
• C. You have misconfigured ASNs.
• D. A generic system has not been configured.

Answer: A

Explanation:
In Juniper Apstra, a blueprint is a logical representation of the network design and configuration. When you create a new blueprint, you need to commit the changes to apply them to the network devices. However, committing the changes does not mean that the network is immediately updated and operational. It may take some time for the network to converge and reflect the new state of the blueprint. During this time, you may see some anomalies related to BGP in the main dashboard, which indicate that the BGP sessions are not established or stable between the devices. These anomalies are usually temporary and will disappear once the network converges and the BGP sessions are up and running. Therefore, the statement B is the most likely cause of these anomalies in this scenario.
The following three statements are less likely causes of these anomalies in this scenario:
* You have misconfigured ASNs. This is possible, but not very likely, because Juniper Apstra provides ASN pools that can be automatically assigned to the devices based on their roles. You can also manually specify the ASNs for the devices, but you need to ensure that they are unique and consistent with the network design. If you have misconfigured ASNs, you may see some anomalies related to BGP, but they will not disappear after the network converges. You will need to fix the ASNs and commit the changes again to resolve the anomalies.
* Spine-leaf links are incorrectly set. This is possible, but not very likely, because Juniper Apstra provides connectivity templates that can be used to define the spine-leaf links based on the interface maps. You can also manually specify the spine-leaf links, but you need to ensure that they are correct and match the physical cabling. If you have incorrectly set the spine-leaf links, you may see some anomalies related to BGP, but they will not disappear after the network converges. You will need to fix the spine-leaf links and commit the changes again to resolve the anomalies.
* A generic system has not been configured. This is not relevant, because a generic system is a device that is not managed by Juniper Apstra, but is connected to the network. A generic system does not affect the BGP sessions between the devices that are managed by Juniper Apstra. If you have a generic system in your network, you need to configure it manually and ensure that it is compatible with the network design. A generic system does not cause any anomalies related to BGP in the main dashboard.

NEW QUESTION # 31
In the Juniper Apstra design phase, which object dictates port count, port speed, and how the ports would be used?

• A. rack type
• B. logical devices
• C. interface map
• D. network devices

Answer: C

Explanation:
Interface maps are objects that map interfaces between logical devices and physical hardware devices in the Juniper Apstra design phase. They dictate port count, port speed, and how the ports would be used for achieving the intended network configuration rendering. Interface maps also allow you to select device ports, transformations, and interfaces, provision breakout ports, and disable unused ports.

NEW QUESTION # 32
What does EVPN use lo identity which remote leaf device advertised the EVPN route?

• A. a VRF target value
• B. a community tag
• C. a route target value
• D. a route distinguisher value

Answer: D

Explanation:
EVPN uses a route distinguisher (RD) value to identify which remote leaf device advertised the EVPN route.
An RD is a 64-bit value that is prepended to the EVPN NLRI to create a unique VPNv4 or VPNv6 prefix. The RD value is usually derived from the IP address of the PE that originates the EVPN route. By comparing the RD values of different EVPN routes, a PE can determine which remote PE advertised the route and which VRF the route belongs to. The other options are incorrect because:
* B. a community tag is wrong because a community tag is an optional transitive BGP attribute that can be used to group destinations that share some common properties. A community tag does not identify the source of the EVPN route.
* C. a route target value is wrong because a route target (RT) value is an extended BGP community that is used to control the import and export of EVPN routes between VRFs. An RT value does not identify the source of the EVPN route.
* D. a VRF target value is wrong because there is no such thing as a VRF target value in EVPN. A VRF is a virtual routing and forwarding instance that isolates the IP traffic of different VPNs on a PE. A VRF does not have a target value associated with it. References:

NEW QUESTION # 33
What is the purpose of an interface map in Juniper Apstra?

• A. An interface map specifies the number of ports and the port speeds of a logical device
• B. An interface map associates a logical device with a device profile.
• C. An interface map specifies the connections between racks in a template.
• D. An interface map specifies a connection between the interfaces of two devices.

Answer: D

Explanation:
According to the Juniper documentation1, an interface map is a configuration template that maps interfaces between logical devices and physical hardware devices (represented with device profiles) while adhering to vendor specifications. An interface map specifies a connection between the interfaces of two devices, such as a leaf and a spine, a leaf and a server, or a leaf and an external gateway. An interface map can also specify port transformations, such as breaking out a 40 GbE port into four 10 GbE ports, or disabling unused ports. An interface map can be used to achieve the intended network configuration rendering and to enable features such as LAG, ESI-LAG, or MLAG. Therefore, the correct answer is B. An interface map specifies a connection between the interfaces of two devices. References: Interface Maps (Datacenter Design)

NEW QUESTION # 34
What is the purpose of a Juniper Apstra rack?

• A. It stores information on how leaf nodes connect to generic devices
• B. It stores information on how pods connect to super spines.
• C. It stores device port data rates and vendor information.
• D. It stores IP address and ASN pool information.

Answer: A

Explanation:
A Juniper Apstra rack is a physical entity that contains one or more network devices, such as leaf nodes, access switches, or generic systems. A rack is used to organize and manage the network devices in the Apstra software application. A rack has the following characteristics:
* It stores information on how leaf nodes connect to generic devices. This is because a rack can include generic systems, which are devices that are not managed by Juniper Apstra, but are connected to the network. A generic system can be a server, a firewall, a load balancer, or any other device that has a networkinterface. A rack stores the information on how the leaf nodes, which are the devices that provide access to the end hosts, connect to the generic devices, such as the port number, the link speed, the LAG mode, and the roles1.
* It has a rack type, which defines the type and number of leaf devices, access switches, and/or generic systems that are used in the rack. A rack type is a resource that is created in the data center design phase, and it does not specify the vendor or the model of the devices. A rack type can be predefined or custom-made, and it can be used to create multiple racks with the same structure and configuration2.
* It has a rack build, which assigns the specific vendor and model of the devices to the rack. A rack build is created in the staged phase, and it uses the rack type as a template. A rack build can also assign the resources, such as the IP addresses, the ASNs, and the VNIs, to the devices in the rack3.
* It has a rack deployment, which applies the network configuration and services to the devices in the rack. A rack deployment is performed in the active phase, and it uses the rack build as a reference. A rack deployment can also monitor the network performance and compliance of the devices in the rack4.
The following three statements are incorrect in this scenario:
* It stores information on how pods connect to super spines. This is not true, because a rack does not store any information on the pod or the super spine level of the network. A pod is a cluster of leaf and spine devices that form a 3-stage Clos topology, and a super spine is a device that connects multiple pods in a
5-stage Clos topology. A rack only stores information on the leaf and the access level of the network1.
* It stores IP address and ASN pool information. This is not true, because a rack does not store any information on the IP address and ASN pools. IP address and ASN pools are resources that are created in the data center design phase, and they contain a range of IP addresses and ASNs that can be assigned to the devices and the virtual networks. A rack only uses the IP address and ASN pools to assign the resources to the devices in the rack build2.
* It stores device port data rates and vendor information. This is not true, because a rack does not store any information on the device port data rates and vendor information. The device port data rates and vendor information are specified in the rack build, which assigns the specific vendor and model of the devices to the rack. A rack only uses the rack build to apply the network configuration and services to the devices in the rack deployment3.

NEW QUESTION # 35
Which three statements describe intent-based analytics? (Choose three.)

• A. It collects information from vendor websites.
• B. It is used to establish network performance baselines.
• C. It indicates when device operating versions require updating.
• D. It is a real-time information processing pipeline.
• E. It alerts the network operator when network performance moves away from the baseline.

Answer: B,D,E

Explanation:
Intent-based analytics (IBA) is a feature of Juniper Apstra that allows you to combine intent from the network design with current and historic data from devices to reason about the network at-large1. IBA has the following characteristics:
* It is a real-time information processing pipeline. This means that IBA can ingest, process, and analyze large amounts of data from devices in real time, using agents and probes. Agents are software components that collect data from devices and send them to the Apstra server. Probes are user-defined queries that aggregate data across devices and generate advanced data that can be more easily reasoned about1.
* It is used to establish network performance baselines. This means that IBA can use the advanced data to measure and monitor the network performance against the expected outcomes and service levels. IBA can also use the historic data to create baselines that represent the normal behavior and state of the network2.
* It alerts the network operator when network performance moves away from the baseline. This means that IBA can detect and report any anomalies or deviations from the baseline or the intent in the network. IBA can also provide insights and recommendations for troubleshooting and resolving the issues2.
The following two statements are incorrect in this scenario:
* It indicates when device operating versions require updating. This is not true, because IBA does not provide any information or guidance about the device operating versions or updates. IBA is focused on the network performance and compliance, not on the device maintenance or upgrade1.
* It collects information from vendor websites. This is not true, because IBA does not collect any information from vendor websites or external sources. IBA only collects information from the devices in the network, using agents and probes1.

NEW QUESTION # 36
Which statement is true when onboarding a Juniper Networks device using a Juniper Apstra ZTP server?

• A. The Hostname will be the serial-number of the device.
• B. The Management IP address cannot be predetermined.
• C. The Device Key lo be used can be set In the dhcpd.conf file on the ZTP server.
• D. The State can be set In the ztp.Json file on the ZTP server.

Answer: D

Explanation:
The ztp.Json file on the Apstra ZTP server contains the configuration parameters for each device that is onboarded using ZTP. One of the parameters is the State, which can be one of the following values: init, ready, in_progress, done, error, or disabled. The State indicates the current status of the device in the ZTP process. For example, if the State is ready, it means that the device is ready to be onboarded by the Apstra ZTP server. If the State is done, it means that the device has completed the ZTP process and is managed by the Apstra server. The State can be manually set or changed in the ztp.Json file to control the behavior of the device during ZTP. For more information, see Apstra ZTP Configuration File. References:

NEW QUESTION # 37
You have a virtual network that needs controlled access to other virtual networks in the same routing zone.
Using the Juniper Apstra Ul. which feature would be used to accomplish this task?

• A. security policy
• B. anti-affinity policy
• C. interface policy
• D. routing policy

Answer: A

Explanation:
A security policy is the feature that would be used to accomplish the task of controlling access to other virtual networks in the same routing zone using the Juniper Apstra UI. A security policy allows you to define rules that specify which traffic is allowed or denied between different virtual networks, IP endpoints, or routing zones. A security policy can be applied to one or more virtual networks in the same routing zone, and it can use various criteria to match the traffic, such as source and destination IP addresses, protocols, ports, or tags. A security policy can also support DHCP relay, which enables the forwarding of DHCP requests from one virtual network to another. The other options are incorrect because:
* A. interface policy is wrong because an interface policy is a feature that allows you to configure the interface parameters for the devices in a blueprint, such as interface names, speeds, types, or descriptions. An interface policy does not affect the access control between different virtual networks in the same routing zone.
* B. anti-affinity policy is wrong because an anti-affinity policy is a feature that allows you to prevent certain devices or logical devices from being placed in thesame rack or leaf pair in a blueprint. An anti-affinity policy is used to enhance the availability and redundancy of the network, not to control the access between different virtual networks in the same routing zone.
* C. routing policy is wrong because a routing policy is a feature that allows you to configure the routing parameters for the devices in a blueprint, such as routing protocols, autonomous system numbers, route filters, or route maps. A routing policy does not affect the access control between different virtual networks in the same routing zone, unless the routing policy is used to filter or modify the routes exchanged between different routing zones.

NEW QUESTION # 39
When working with logical devices, you specify where each port group is connected.
In thisscenario, which two Juniper Apstra Ul options are available to the operator? {Choose two.)

• A. router
• B. generic
• C. firewall
• D. unused

Answer: B,D

Explanation:
When working with logical devices, you specify where each port group is connected by selecting the port group layout and the port speed and role (s) for each port group. The Juniper Apstra UI offers two options to the operator for the port group role: unused and generic1.
* Unused: This option means that the port group is not configured or used by Apstra. This can be useful for ports that are faulty, reserved, or not part of the data center fabric1.
* Generic: This option means that the port group is configured with a generic role that is not specific to any device type or function. This can be useful for ports that are used for testing, troubleshooting, or custom purposes1. References:

NEW QUESTION # 40
Within Managed Devices in the Juniper Apstra Ul, you notice that several devices have the OOS-Quarantined status. The devices cannot be added to any blueprint. Which action would solve this problem?

• A. Upload a new pristine configuration.
• B. Fix the hardware issues with the quarantined devices.
• C. Install the agent, even though connectivity is established.
• D. Acknowledge the device.

Answer: D

Explanation:
When an agent installation is successful, devices are placed into the Out of Service Quarantined (OOS-QUARANTINED) state using the Juniper Apstra UI. This state means that the device is not yet managed by Apstra and has not been assigned to any blueprint. The device configuration at this point is called Pristine Config. To make the device ready for use in a blueprint, you need to acknowledge the device, which is a manual action that confirms the device identity and ownership. Acknowledging the device changes its status to Out of Service Ready (OOS-READY)12. References:

Exhibit.

Which two statements ate correct about the graph query output shown in the exhibit? (Choose two.)

• A. The interface has an IP address assigned to it.
• B. The switch in the output is a Juniper device.
• C. The output shows a LAG connection.
• D. The interface has tags assigned to it.

Answer: B,C

Explanation:
The graph query output shown in the exhibit is a JSON representation of an interface node and its properties in the Apstra graph database. Based on the output, we can infer the following statements:
* The output shows a LAG connection. This is true because the interface node has a property called lag_mode which is set to lacp_active, indicating that the interface is part of a link aggregation group (LAG) that uses the Link Aggregation Control Protocol (LACP) to negotiate the link state and parameters12.
* The switch in the output is a Juniper device. This is true because the interface node has a property called if_name which is set to ae2, indicating that the interface name follows the Juniper naming convention for aggregated Ethernet interfaces34.
* The interface has an IP address assigned to it. This is false because the interface node has properties called ipv4_addr and ipv6_addr which are both set to null, indicating that the interface does not have any IPv4 or IPv6 address configured2.
* The interface has tags assigned to it. This is false because the interface node has a property called tags which is set to null, indicating that the interface does not have any tags associated with it2.

NEW QUESTION # 42
Which fabric type should be chosen in a template to create a five-stage Clos?

• A. collapsed
• B. circuit switched
• C. pod-based
• D. rack-based

Answer: C

Explanation:
According to the Juniper documentation1, a five-stage Clos architecture allows for large-scale topologies with an additional aggregation layer that interconnects multiple pods into a single fabric. A pod is a group of racks that share the same spine devices. A rack is a group of leaf devices that connect to the same servers. To create a five-stage Clos network using Juniper Apstra, you need to choose the pod-based fabric type in the template creation wizard. This will allow you to specify the number of pods, planes, spines, and leaves for your network design. Therefore, the correct answer is D. pod-based.

Exhibit.

Referring to the exhibit, how do you display the IPv6 subnets lot all of the listed VXLANs?

• A. Select Columns, then select IPv6 Subnet.
• B. An IPv6 Subnets column is not shown, indicating that no VXLAN has an assigned IPv6 subnet
• C. IPv6 subnets ate shown when each VXLAN is selected individually.
• D. Select all VXLANs. and the IPv6 Subnets column will appear

Answer: A

Explanation:
Referring to the exhibit, the image shows a user interface of the Juniper Apstra software application, which is used for network management and configuration. The image shows the Virtual Networks table under the Resources menu, which displays the details of the VLANs and VXLANs in the network. The table has 11 columns, but only 9 are visible in the image. The other two columns are IPv6 Connectivity and IPv6 Subnet, which are hidden by default. To display the IPv6 subnets for all of the listed VXLANs, the user needs to select Columns, then select IPv6 Subnet.

NEW QUESTION # 44
Exhibit.

Which two statements about ESI values are correct for the server connections to the fabric shown in the exhibit? (Choose two.)

• A. A valid ESI value for Server A is 0x00.10.10.10.10.10.10.10.10.10.
• B. A valid ESI value for Server A is 0x00.00.00.00.00.00.00.00.00.00.
• C. A valid ESI value for Server B is 0x00.00.00.00.00.00.00.00.00.00.
• D. A valid ESI value for Server B is 0x00.20.20.20.20.20.20.20.20.20.

Answer: A,C

Explanation:
To answer this question, we need to understand the concept of ESI values in EVPN LAGs. An ESI is a 10-byte value that identifies an Ethernet segment, which is a set of links that connect a multihomed device (such as a server) to one or more PE devices (such as leaf switches) in an EVPN network. The same ESI value must be configured on all the PE devices that connect to the same Ethernet segment. This allows the PE devices to form an EVPN LAG, which supports active-active or active-standby multihoming for the device. The ESI value can be manually configured (type 0) or automatically derived from LACP (type 1) or other methods. In the exhibit, Server A is connected to two leaf switches (QFX 5210) using a LAG with LACP enabled. Server B is connected to three leaf switches (QFX 5120) using a LAG with LACP enabled. Based on this information, the following statements are correct about ESI values for the server connections to the fabric:
* C. A valid ESI value for Server A is 0x00.10.10.10.10.10.10.10.10.10. This is true because this ESI value can be automatically derived from the LACP configuration on the QFX 5210 devices. The LACP system ID is usually based on the MAC address of the device, and the LACP administrative key is a
2-byte value that identifies the LAG. For example, if the MAC address of the QFX 5210 device is
00:10:10:10:10:10 and the LAG ID is 10, then the LACP system ID is 00:10:10:10:10:10 and the LACP administrative key is 00:0A. The ESI value is then derived by concatenating the LACP system ID and the LACP administrative key, resulting in 00:10:10:10:10:10:00:0A. This ESI value can be represented in hexadecimal notation as 0x00.10.10.10.10.10.00.0A, or padded with zeros as
0x00.10.10.10.10.10.00.0A.00.00. This ESI value must be configured on both QFX 5210 devices that connect to Server A.
* D. A valid ESI value for Server B is 0x00.00.00.00.00.00.00.00.00.00. This is true because this ESI value is a reserved value that indicates a single-homed device. Server B is connected to three leaf switches (QFX 5120) using a LAG, but it is not multihomed to any of them. This means that Server B does not need an ESI value to form an EVPN LAG with any of the leaf switches. Instead, Server B can use the reserved ESI value of 0x00.00.00.00.00.00.00.00.00.00, which indicates that it is a single-homed device and does not participate in any EVPN LAG. This ESI value must be configured on all three QFX
5120 devices that connect to Server B. Thefollowing statements are incorrect about ESI values for the server connections to the fabric:
* A. A valid ESI value for Server A is 0x00.00.00.00.00.00.00.00.00.00. This is false because this ESI value is a reserved value that indicates a single-homed device. Server A is connected to two leaf switches (QFX 5210) using a LAG with LACP enabled, which means that it is multihomed to both of them. This means that Server A needs an ESI value to form an EVPN LAG with the leaf switches. The ESI value must be unique and non-zero for each Ethernet segment, so the reserved ESI value of
0x00.00.00.00.00.00.00.00.00.00 is not valid for Server A.
* B. A valid ESI value for Server B is 0x00.20.20.20.20.20.20.20.20.20. This is false because this ESI value is not derived from the LACP configuration on the QFX 5120 devices. Server B is connected to three leaf switches (QFX 5120) using a LAG with LACP enabled, but it is not multihomed to any of them. This means that Server B does not need an ESI value to form an EVPN LAG with any of the leaf switches. Instead, Server B can use the reserved ESI value of 0x00.00.00.00.00.00.00.00.00.00, which indicates that it is a single-homed device and does not participate in any EVPN LAG. The ESI value of
0x00.20.20.20.20.20.20.20.20.20 is not valid for Server B, and it may cause conflicts with other Ethernet segments that use the same ESI value. References:
