Implementing Cisco ACI Advanced (DCACIA) — Question 19

An existing Cisco ACI Multi-Site setup with default fabric settings contains endpoints that communicate with an MTU of 1500. What is the minimum MTU value that must be supported by the ISN to allow control plane endpoint information exchange between sites?

Answer options

• A. 9000
• B. 1554
• C. 9100
• D. 1600

Correct answer: C

Explanation

The correct answer is C, 9100, as this MTU value is necessary to accommodate the overhead from encapsulation and ensure proper communication between sites. Options A, B, and D do not provide sufficient MTU support for the control plane endpoint information exchange, as they are either too high or too low compared to the requirements.
