Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 588

What are two characteristics of a VRF instance? (Choose two.)

Answer options

• A. A customer site can be associated to different VRFs.
• B. Each VRF has a different set of routing and CEF tables.
• C. It is defined by the VPN membership of a customer site attached to a P device.
• D. All VRFs share customers routing and CEF tables.
• E. An interface must be associated to one VRF.

Correct answer: B, E

Explanation

The correct options are B and E because each VRF has its own distinct routing and CEF tables, ensuring separation of traffic, and an interface can only belong to one VRF to maintain this separation. Options A and C are incorrect as they misrepresent the relationships between customer sites and VRFs, while D incorrectly states that all VRFs share routing and CEF tables, which contradicts the principle of VRF isolation.
