Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 11
What is the NHRP role in DMVPN? (Choose two.)
Answer options
- A. Obtains the next-hop to be used for routing
- B. Routes the packet through the tunnel
- C. Identifies the PIM-SM RP used to route the packet
- D. Can authenticate VPN endpoints
- E. It requires each tunnel endpoint to have a unique network ID
Correct answer: A, D
Explanation
The correct answers are A and D because NHRP's primary function is to obtain the next-hop information for routing (A) and it can also authenticate VPN endpoints (D). Options B, C, and E are incorrect as NHRP does not route packets directly, is not involved in identifying PIM-SM RPs, and does not require a unique network ID for each endpoint.
