Answer analysis

Option-by-option breakdown

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

  • set interfaces ge-0/0/25 lldp-state off

    Why it's wrong here

    Junos interface hierarchy does not contain lldp-state parameters.

  • set ethernet-switching-options lldp interface ge-0/0/25 restrict

    Why it's wrong here

    This command syntax is incorrect.

  • set protocols lldp interface ge-0/0/25 action block

    Why it's wrong here

    action block is not a valid Junos LLDP command.

  • set protocols lldp interface ge-0/0/25 disable

    Why this is correct

    Adding the disable option under protocols lldp interface stops LLDP transmission and reception on that specific port.
