   A data center has two leaf switches providing multihomed connectivity to a server using an ESI LAG. The network team notices that during normal operation, all traffic from the server is being forwarded by only one of the leaf switches, while the other leaf is idle. They want to utilize both leaves for traffic while maintaining redundancy. What should they do?

   • AUse a single leaf switch and connect the server with a regular LAG to avoid the complexity of ESI LAG.
   • BConfigure the ESI LAG with a different ESI on each leaf switch.
   • CIncrease the bandwidth of the active leaf's uplink to the spine to handle all traffic.
   • DEnable per-flow load balancing on the ESI LAG and ensure that the EVPN design uses all-active multihoming.

   What is the primary purpose of redundant links in a network design?

   • ATo reduce the number of switches required in the network
   • BTo simplify the configuration of routing protocols
   • CTo increase the security of the network by encrypting traffic
   • DTo provide an alternate path for traffic if a primary link fails

   In a high-resiliency design, what is the purpose of failure domain isolation?

   • ATo simplify network management by reducing the number of devices
   • BTo guarantee that all traffic uses the same physical path
   • CTo provide duplicate hardware for every network device
   • DTo ensure that a failure in one part of the network does not cascade to other parts
