Correct answer & explanation

✓

The spoke 10.0.0.2 has registered with the hub and its NBMA address is 192.168.1.2.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    The spoke 10.0.0.2 has registered with the hub and its NBMA address is 192.168.1.2.

    Why this is correct

    Correct: The entry is dynamic, unique, registered, and shows the NBMA address.

  • ✗

    The spoke 10.0.0.2 is using a static NBMA mapping.

    Why it's wrong here

    Incorrect because the type is 'dynamic', not static.

  • ✗

    The NHRP entry is about to expire and needs re-registration.

    Why it's wrong here

    Incorrect because the expire time is 01:49:45, which is not near expiry.

  • ✗

    The spoke has not registered; the entry is incomplete.

    Why it's wrong here

    Incorrect because the flags include 'registered'.

Variation 1. A network engineer runs the following command to troubleshoot a DMVPN spoke not registering with the hub: R2# debug nhrp NHRP: Send Registration Request via Tunnel0 10.0.0.2, target 10.0.0.1 NHRP: Receive Registration Reply via Tunnel0 10.0.0.1, src 10.0.0.1, dst 10.0.0.2 NHRP: Registration successful for 10.0.0.2/32 via Tunnel0 What does this output indicate?

medium
  • A.The spoke is unable to reach the hub; the registration request is being sent but no reply is received.
  • ✓ B.The spoke has successfully registered its tunnel IP 10.0.0.2/32 with the hub at 10.0.0.1.
  • C.The spoke is sending a registration request to 10.0.0.1 but the hub is not responding, causing a timeout.
  • D.The spoke is attempting to register with the wrong hub IP address.

Why B: The debug output shows a successful NHRP registration: the spoke sends a registration request to the hub and receives a reply, confirming that the spoke's tunnel IP is registered with the hub.
