   A data center fabric uses eBGP as the underlay. Each leaf advertises its directly connected /31 link networks to the spines. The network team wants to reduce the number of routes in the fabric and simplify troubleshooting. What should they implement?

   • ARoute filtering on the leaves
   • BBGP multipath on the spines
   • COSPF on the spines
   • DRoute summarization on the spines

   A company is designing a new data center fabric with a spine-and-leaf topology. They want to ensure that the fabric can provide high availability and load balancing across multiple paths. What is the primary benefit of using IP fabric routing in this design?

   • AIt eliminates the need for a routing protocol
   • BIt requires a full mesh of links between all switches
   • CIt enables ECMP across multiple equal-cost paths
   • DIt uses spanning tree to prevent loops

   A leaf switch in an eBGP IP fabric has four equal-cost uplinks to four spines. The network team notices that traffic to a particular destination is always using the same uplink, even though other destinations are load-balanced. What is the most likely cause?

   • AThe BGP multipath is not enabled
   • BThe destination prefix is not in the routing table
   • CThe spines are not advertising the same prefix
   • DThe hash algorithm is using only the source IP address

   A leaf switch in an OSPF-based IP fabric is experiencing route flapping. The engineer notices that the OSPF adjacency with a spine is going up and down repeatedly. What is the most likely cause?

   • AThe OSPF area ID is different on the two devices
   • BThe OSPF hello and dead intervals are mismatched
   • CThe OSPF network type is point-to-point on one side and broadcast on the other
   • DThe OSPF router ID is the same on both devices

   In a BGP EVPN fabric, a leaf switch is not receiving MAC routes for a tenant VNI from a remote leaf. The underlay is healthy and the BGP session is established. What should the engineer check first?

   • AThe underlay routing table on the remote leaf
   • BThe VXLAN VNI ID on the local leaf
   • CRoute target configuration on the VNI
   • DThe BGP AS number on the remote leaf
