QUESTION 1
A vPC Type-1 inconsistency between two vPC peers in a VXLAN EVPN setup is discovered.
Which two actions need to be attempted to resolve the issue? (Choose two.)

A. Configure the NVE interfaces to be Up on both switches.
B. Set a different distributed gateway virtual MAC address.
C. Set a different secondary IP addresses on NVE source-interface.
D. Configure the same VNI to multicast group maping.
E. Set a different primary IP addresses on NVE source-interface.

Answer: A,D

QUESTION 2
A mission-critical server is connected to site
A. Connectivity to this server is lost from site B because the MAC
route is missing in the OTV VDC of the Cisco Nexus 7000 in site B due to MAC aging.
Which action allows the flooding of the unknown unicast MAC on the Nexus 7000 in the OTV VDC?

A. Use route map to statically advertise this MAC and redistribute with IS-IS.
B. Unknown unicast flooding is not allowed.
C. Use the otv flood mac <> command to selectively flood traffic for a given MAC.
D. Use the otv isis bfd <> command to configure BFD protocol.

Answer: B

QUESTION 3
The Cisco Nexus switch is connected to a peer switch that is not running Cisco NX-OS.
The switches are connected using port channel and are experiencing packet loss. Which action should be performed on the
Cisco Nexus switch ports to resolve this issue?

A. Turn on lacp suspend-individual.
B. Turn on lacp graceful-convergence.
C. Turn off lacp graceful-convergence.
D. Turn off lacp suspend-individual.

Answer: C
