JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2021) — Question 27

What are three label operations that an MPLS-enabled router performs? (Choose three.)

Answer options

• A. swap
• B. push
• C. pop
• D. insert
• E. rewrite

Correct answer: A, B, C

Explanation

The correct operations performed by an MPLS-enabled router include swap, push, and pop. Swap refers to replacing the top label with a new one, push adds a new label to the stack, and pop removes the top label. The options insert and rewrite are not standard MPLS operations, thus they are incorrect.
