Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 381

In an MPLS VPN network, how are customer routes controlled and distributed?

Answer options

• A. Through the use of GRE tunnels
• B. Customer routes are redistributed into the IGP that the service provider is using
• C. Customer routes are redistributed into BGP within the service provider
• D. It is distributed through the use of route targets

Correct answer: D

Explanation

The correct answer is D because route targets enable the identification and distribution of VPN routes among different VPNs in an MPLS VPN architecture. Options A, B, and C are incorrect as they do not accurately describe the mechanism of route distribution specific to MPLS VPNs, where route targets play a crucial role.
