JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 24

You notice that currently two MAC addresses are associated with a single access port in the bridge table of one of your EX Series switches.
What are two explanations for this behavior? (Choose two.)

Answer options

Correct answer: C, D

Explanation

The correct answers are C and D because an IP phone can connect to a host device, resulting in two MAC addresses appearing on the same port. Similarly, a rogue device could aggregate multiple hosts to a single access port, leading to multiple MAC addresses. Options A and B do not explain the presence of two MAC addresses in this scenario.
