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.
