Which mechanism would explain why traffic is taking a sub-optimal path despite a policy favoring a different link?

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

Path health failure

If the preferred path fails the path-health check, the ION will automatically fail over to a sub-optimal path.

Answer analysis

Option-by-option breakdown

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

  • BGP route dampening

    Why it's wrong here

    Rarely causes path issues in standard deployments.

  • QoS policy override

    Why it's wrong here

    QoS does not control path selection.

  • Duplicate IP address

    Why it's wrong here

    Would cause broader network instability.

  • Path health failure

    Why this is correct

    Failover occurs automatically when the preferred path is deemed unhealthy.
