JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 41

You have DHCP snooping enabled but no entries are automatically created in the snooping database for an interface on your EX Series switch.
What are two reasons for the problem? (Choose two.)

Answer options

• A. The device that is connected to the interface has performed a DHCPRELEASE.
• B. MAC limiting is enabled on the interface.
• C. The device that is connected to the interface has a static IP address.
• D. Dynamic ARP inspection is enabled on the interface.

Correct answer: A, C

Explanation

Option A is correct because a DHCPRELEASE indicates that the device is no longer using the IP address, so no entry will be created. Option C is also correct as a device with a static IP address will not request an IP via DHCP, preventing any entries from being logged in the snooping database. Options B and D do not directly affect the creation of DHCP snooping entries.
