   Which issue is commonly indicated by a 'no route to host' error when troubleshooting underlay connectivity in a campus fabric?

   • AThe underlay routing protocol is not establishing adjacencies or routes are missing.
   • BThe VXLAN tunnel is down.
   • CThe VLAN is not configured on the access port.

   A company is migrating from a legacy campus network to a Juniper campus fabric. The legacy network uses a spanning tree protocol (STP) and has multiple VLANs. The migration must be completed without any downtime, and the new fabric must be able to communicate with the legacy network during the transition. Which approach should be used to ensure coexistence?

   • AUse a firewall between the legacy network and the fabric to control traffic.
   • BDeploy the fabric as a new routing domain and use VXLAN to extend VLANs to the fabric, while keeping STP on the legacy network.
   • CUse a router to connect the legacy network to the fabric, but do not extend VLANs.
   • DReplace the legacy network with the fabric in a single cutover.

   Which statement correctly describes the underlay network in a Juniper campus fabric?

   • AIt uses VXLAN tunnels to carry encapsulated traffic between leaf switches.
   • BIt is a separate management network used only for device administration.
   • CIt provides Layer 2 connectivity between end devices using VLANs and spanning tree.
   • DIt is an IP-based network that provides Layer 3 connectivity between spine and leaf switches.

   A network engineer is designing the underlay for a campus fabric. The fabric will have 8 spines and 40 leaves. The engineer wants to use a routing protocol that scales well and provides fast convergence. Which routing protocol should the engineer use for the underlay?

   • AOSPF with a single area
   • BeBGP with a private ASN for each leaf and a single ASN for all spines
   • CIS-IS
   • DRIP

   What is the primary purpose of the overlay network in a campus fabric using EVPN-VXLAN?

   • ATo provide Layer 3 routing between spine and leaf switches using OSPF.
   • BTo provide Layer 2 and Layer 3 services to end devices across the IP fabric.
   • CTo replace the need for VLANs by using a single broadcast domain.
   • DTo provide a dedicated management channel for Mist AI.
