Juniper Exam JN0-480 Topic 7 Question 34 Discussion

To create a new routing zone, you must specify the VRF Name, VLAN ID, and VNI for the routing zone. These are the mandatory fields in the user interface shown in the exhibit. The VRF Name is the name of the L3 domain that isolates the IP traffic of the routing zone from other routing zones. The VLAN ID is the identifier for the VLAN tagged Layer 3 links on external connections. The VNI is the VxLAN Network Identifier associated with the routing zone. The Routing Policies are optional fields that allow you to configure import and export route targets for the routing zone. These are only applicable for EVPN routing zones, which use MP-EBGP as the overlay control protocol. The other options are incorrect because:

A) VRF Name only is wrong because you also need to specify the VLAN ID and VNI for the routing zone.

B) VRF Name and Routing policies is wrong because you also need to specify the VLAN ID and VNI for the routing zone. Routing policies are optional and only relevant for EVPN routing zones.

D) VRF Name, VLAN ID, VNI, Routing Policies is wrong because Routing Policies are optional and not required to create a new routing zone.Reference:
