CCIE Data Center (legacy) — Question 29

Which two parameters must be identical per interface while configuring virtual port channels. (Choose two.)

Answer options

• A. network access control
• B. Bridge Assurance setting
• C. IP Source Guard
• D. maximum transmission unit
• E. Protocol Independent Multicast

Correct answer: A, B

Explanation

The correct answer includes 'network access control' and 'Bridge Assurance setting' because these parameters must match across all interfaces in a virtual port channel to ensure proper functionality. The other options, while important in their own contexts, do not need to be identical for the virtual port channel configuration.
