JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 17

What are two functions of bridging? (Choose two.)

Answer options

• A. blocking
• B. aging
• C. listening
• D. forwarding

Correct answer: B, D

Explanation

The correct answers are B and D because 'aging' refers to the process of removing outdated entries from the bridge's MAC address table, while 'forwarding' is the action of sending frames to the appropriate destination. Options A and C are not correct as 'blocking' refers to preventing traffic on certain ports, and 'listening' is a state that does not forward frames.
