NSE7 Troubleshooting and Diagnostics Practice Question

A FortiGate is configured with multiple BGP peers. One of the peers is not receiving the expected routes. The administrator runs 'get router info bgp neighbors <IP>' and sees that the 'State/PfxRcd' field is 'Active'. What does this indicate?

⚠ Common exam trap

Watch out — candidates often confuse 'Active' with 'Established' because both sound like the session is working, but 'Active' actually means the TCP connection has not been completed, while 'Established' is the only state where routes are exchanged.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

The BGP session is in the Active state, meaning the FortiGate is trying to establish a TCP connection to the peer

The 'Active' state in BGP indicates that the FortiGate has sent an OPEN message and is waiting for a TCP connection from the peer, or is actively retrying the TCP connection. This means the session has not yet reached the Established state, so no routes are being exchanged. Option C correctly identifies that the FortiGate is attempting to establish a TCP connection to the peer.

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 BGP peer has reached the maximum prefix limit

    Why it's wrong here

    Maximum prefix limit would typically cause the session to be reset or go to Idle.

  • The BGP peer has been administratively shut down

    Why it's wrong here

    Administratively shutdown would show 'Idle' or 'Admin' state.

  • The BGP session is in the Active state, meaning the FortiGate is trying to establish a TCP connection to the peer

    Why this is correct

    Active state indicates the router is actively trying to initiate a TCP connection to the peer, but the session is not yet up.

  • The BGP session has been established and routes are being exchanged

    Why it's wrong here

    In Active state, the session is not established; it is attempting to connect.
