Refer to the exhibit. One of the vPC VTEPs fails to route VXLAN traffic to vPC connected hosts. When the issue was being diagnosed, it was discovered that the packets that were expected to be forwarded to the MAC address on the SWITCH-VTEP-1 are instead forwarded to the MAC address on SWITCH-VTEP-2 and then dropped. Which action resolves the issue?
- A. Configure a distributed anycast gateway on both peers
- B. Configure ip arp synchronize under the VPC domain on both peers
- C. Configure peer-gateway under the VPC domain on both peers

- D. Change router ID on Router R10
Answer : B
Refer to the exhibit. A customer network uses OSPFv2 and MP-BGP protocols. A network administrator installs a new Cisco Nexus Switch in the data center but experiences a BGP RIB failure. Which action solves the issue?
- A. Change the administrative distance of OSPF to 220
- B. Configure the route as a BGP backdoor
- C. Use a filter list for OSPF to filter both routes
- D. Implement next-hop-self
Answer : D
An engineer is implementing a new BGP peering in their new data center. The engineer set up the BGP session that peers with the remote end. As soon as the BGP peers attempt to exchange routing prefixes, one of the BGP peers drops the connection. After reviewing the configuration, the engineer reviews the logging messages. The engineer discovers that the router is missing keepalives from the remote end and terminates the session. Which action resolves the issue?
- A. Set the bgp transport path-mtu-discovery attribute on both peers
- B. Set the higher values for the BGP keepalive and hold-down timers on both peers
- C. Configure the matching BGP AS numbers between the peers
- D. Configure the matching BGP passwords between the peers
Answer : B
