Show Suggested Answer Hide Answer
Suggested Answer: D

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. For virtual networks with Layer 3 SVI, the SVI is associated with a Virtual Routing and Forwarding (VRF) instance for each routing zone isolating the virtual network SVI from other virtual network SVIs in other routing zones. Therefore, the correct answer is D. A routing zone is used to enable the communication between two VNIs within a VRF. A routing zone is not used for L4-L7 inspection, securing routing protocols, or requiring firewalls. Those are not the purposes of a routing zone in Juniper Apstra software.Reference:Routing Zones

I'm not sure about option D. Can someone explain why the underlay EBGP peering's must be established between leaf and spine devices?

I agree with Georgene. Option C makes sense for establishing proper communication in the EVPN-VXLAN data center fabric.

Option D seems correct to me. The underlay must have EBGP peering established between leaf and spine devices to enable the EVPN-VXLAN overlay.

I think option C is correct because loopback IPv4 addresses need to be advertised into the EBGP underlay.
