Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 76

After a Cisco Nexus 7000 Series Switch chassis replacement, the administrator discovers that all vPC-enabled LACP port channels are reinitialized. The administrator wants to prevent this issue the next time the chassis is replaced. Which two actions must be taken to meet this requirement before the isolated device is reloaded? (Choose two.)

Answer options

• A. Change the vPC system-priority of the replacement chassis to a higher value than the peer
• B. Set the vPC MAC address to a higher value than the peer
• C. Configure auto-recovery to the disable state on both peers
• D. Set the vPC MAC address to a lower value than the peer
• E. Change the vPC system-priority of the replacement chassis to a lower value than the peer

Correct answer: B, C

Explanation

The correct actions are to set the vPC MAC address to a higher value than the peer and to disable auto-recovery on both peers. This prevents the reinitialization of port channels when the new chassis is introduced. The other options may not adequately address the issue or could lead to further complications during the chassis replacement process.
