JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 40

Which two statements about redundant trunk groups on EX Series switches are correct? (Choose two.)

Answer options

• A. Redundant trunk groups load-balance traffic across two designated uplink interfaces.
• B. If the active link fails, then the secondary link automatically takes over.
• C. Layer 2 control traffic is permitted on the secondary link.
• D. Redundant trunk groups must be connected to the same aggregation switch.

Correct answer: B, C

Explanation

Option B is correct because the secondary link is designed to take over automatically if the active link fails, ensuring continuity. Option C is also correct as it states that Layer 2 control traffic can flow through the secondary link. Options A and D are incorrect because they either misrepresent the function of redundant trunk groups or impose unnecessary requirements on connectivity.
