Arista Certified Engineer – Associate (ACE-A) — Question 18

When configuring MLAG, Arista recommends that the trunk group command be used on the VLAN used for MLAG peer communication. What is the purpose of the trunk group command?

Answer options

• A. It groups all the trunks together so that they can traverse the peer-link properly.
• B. It groups the MLAG interfaces together so that they can be reported on both peers.
• C. It prevents the configured VLAN from leaking out onto other trunks.
• D. It ensures that the configured VLAN will be included on all trunks.

Correct answer: A

Explanation

The correct answer, A, is right because the trunk group command ensures that all trunks function together properly over the peer-link, enabling effective communication. Option B is incorrect because it refers to reporting MLAG interfaces rather than trunk functionality. Option C is wrong as it focuses on VLAN leakage, while Option D is not entirely accurate since it does not specify the purpose related to the peer-link.
