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

  1. collapsed
  2. circuit switched
  3. rack-based
  4. pod-based

Answer(s): D

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.

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

  1. IPv6 subnets ate shown when each VXLAN is selected individually.
  2. Select Columns, then select IPv6 Subnet.
  3. Select all VXLANs. and the IPv6 Subnets column will appear
  4. An IPv6 Subnets column is not shown, indicating that no VXLAN has an assigned IPv6 subnet

Answer(s): B

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. This will show the IPv6 Subnet column in the table, which will display the IPv6 addresses assigned to the VXLANs from the IPv6 pools. For more information, see Virtual Networks (Resources).

You want to apply a configlet to a specific device using Juniper Apstr

  1. Which two parameters would be used to accomplish this task? (Choose two.)
  2. form factor
  3. hostname
  4. port group
  5. tags

Answer(s): 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.

What does EVPN use lo identity which remote leaf device advertised the EVPN route?

  1. a route distinguisher value
  2. a community tag
  3. a route target value
  4. a VRF target value

Answer(s): A

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.
