The correct answer is A. The ge-0/0/0 interface was added to the candidate configuration. C. Area 1 was added to the candidate configuration. The show | compare output indicates that the disable statement was removed from ge-0/0/0.0 within OSPF Area 0.0.0.0 in the candidate configuration, and OSPF Area 0.0.0.1 including interface ge-0/0/0.0 was entirely added to the candidate configuration.
Question
Referring to the exhibit, what are two differences between the active and candidate configurations? (Choose two.) user@router# show | compare [edit protocols ospf area 0.0.0.0]
- interface ge-0/0/0.0 {
- disable;
- }
[edit protocols ospf] area 0.0.0.0 { ... } + area 0.0.0.1 { + interface ge-0/0/0.0; + }
Options
- AThe ge-0/0/0 interface was added to the candidate configuration.
- BArea 0 was added to the active configuration.
- CArea 1 was added to the candidate configuration.
- DThe ge-0/0/0 interface was added to the active configuration.

Why each option
The `show | compare` output indicates that the `disable` statement was removed from `ge-0/0/0.0` within `OSPF Area 0.0.0.0` in the candidate configuration, and `OSPF Area 0.0.0.1` including `interface ge-0/0/0.0` was entirely added to the candidate configuration.
The line `- interface ge-0/0/0.0 {{ - disable; - }}` indicates that the `disable` statement was removed from `ge-0/0/0.0` in Area 0.0.0.0 within the candidate configuration, effectively making the interface an active participant.
The `show | compare` output illustrates differences from the active to the candidate configuration, not additions to the active configuration.
The lines starting with `+` within `+ area 0.0.0.1 {{ + interface ge-0/0/0.0; + }}` clearly show that OSPF Area 0.0.0.1 and its interface were entirely added to the candidate configuration.
The `+` and `-` symbols reflect changes that are present in the candidate configuration relative to the active, not changes that have already been applied to the active configuration.
