JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 90

You deployed a new EX Series switch with DHCP snooping enabled and you do not see any entries in the snooping databases for an interface.

Which two Juniper configurations for that interface caused this issue? (Choose two.)

Answer options

• A. The interface is configured as a trunk port.
• B. MAC limiting is enabled on the interface.
• C. Dynamic ARP inspection is enabled on the interface.
• D. The interface is configured as a disabled port.

Correct answer: A, D

Explanation

The correct answers are A and D because a trunk port does not allow DHCP snooping to function properly, and a disabled port will not participate in any traffic, including DHCP. Options B and C are unrelated to the DHCP snooping process and would not prevent entries from being recorded in the snooping database.
