Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 489

What are the two major components of an MPLS-based VPN? (Choose two.)

Answer options

• A. VPN route distinguisher
• B. MP-BGP peering of VPN community CE devices
• C. MP-BGP peering of VPN community P devices
• D. MP-BGP peering of VPN community PE devices
• E. VPN route target communities
• F. VPN route reflectors

Correct answer: D, E

Explanation

The correct answers are D and E because MP-BGP peering of VPN community PE devices facilitates the exchange of routing information between provider edge devices, while VPN route target communities are used to control the distribution of VPN routes. The other options do not represent the two major components necessary for establishing an MPLS-based VPN.
