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

    Why it's wrong here

    The match-port parameter is not part of the standard policy command set.

  • show security flow session destination-port 443

    Why this is correct

    Correct. Filtering sessions by destination-port provides targeted troubleshooting visibility.

  • show route protocol bgp port 443

    Why it's wrong here

  • show firewall filter port 443

    Why it's wrong here

    Firewall filter show commands require specific filter names, not direct port arguments.
