JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2023) — Question 53

What are two bridging concepts that are used to maintain an Ethernet switching table? (Choose two.)

Answer options

• A. learning
• B. exporting
• C. aging
• D. timing

Correct answer: A, C

Explanation

The correct answers are A and C because 'learning' refers to how switches record MAC addresses in their tables, while 'aging' is the process of removing old entries that are no longer in use. Options B and D are incorrect as 'exporting' does not pertain to maintaining the switching table, and 'timing' is not a recognized concept in this context.
