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

Answer analysis

Option-by-option breakdown

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

  • show vlans interface ge-0/0/2

    Why it's wrong here

    This is not a valid Junos operational command.

  • show bridge-domain interface

    Why it's wrong here

    Bridge-domain commands do not apply to standard enterprise switch port modes.

  • show interfaces ge-0/0/2 extensive

    Why it's wrong here

    While extensive shows physical and link layer parameters, it does not format the Layer 2 Ethernet switching details as clearly as the ethernet-switching command.

  • show ethernet-switching interface ge-0/0/2 detail

    Why this is correct

    Correct. This command shows detailed Layer 2 switching configuration and operational state per interface.

Visual reference

Switch VLAN 10 Sales (192.168.10.0/24) PC-A PC-B VLAN 20 HR (192.168.20.0/24) PC-C PC-D Router VLANs isolate traffic — inter-VLAN routing requires a Layer 3 device
