What are three types of MPLS routers? (Choose three.)

Answer options

• A. transit routers
• B. egress routers
• C. peering routers
• D. aggregation routers
• E. ingress routers

Correct answer: A, B, E

Explanation

The correct answers are transit routers, egress routers, and ingress routers, as these play specific roles in the MPLS architecture. Transit routers forward traffic through the MPLS network, egress routers handle traffic leaving the MPLS network, and ingress routers are where traffic enters the MPLS system. Peering routers and aggregation routers are not standard categories in MPLS terminology.
