JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2023) — Question 26

Which two statements are correct about a functional ESI LAG interface? (Choose two.)

Answer options

• A. The LACP system ID must be the same.
• B. The ESI values must be the same.
• C. The LACP system ID must be different.
• D. The ESI values must be different.

Correct answer: A, B

Explanation

The correct answers are A and B because for a functional ESI LAG interface, both the LACP system ID and ESI values must be the same across the participating interfaces to ensure proper aggregation and functionality. Options C and D are incorrect as they state that the IDs and values should be different, which would lead to misconfiguration and potential interface issues.
