Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 294

Cisco Nexus 9000 Series Switches are configured with LACP protocol and default aging timers. What is the impact on the LACP peer during an ISSU upgrade?

Answer options

• A. The LACP peer renegotiates the adjacency.
• B. The LACP peer connection terminates.
• C. The LACP peer connection resets.
• D. The LACP peer session remains up.

Correct answer: D

Explanation

During an ISSU upgrade, the LACP peer session remains up, which means that the connection is not disrupted. This is because LACP is designed to maintain its state even during software upgrades, unlike the other options which would imply a loss of connectivity or session state.
