Private configuration mode in Junos OS provides each user with an isolated candidate configuration, and committing changes only applies that user's specific modifications.

Why each option

Private configuration mode in Junos OS provides each user with an isolated candidate configuration, and committing changes only applies that user's specific modifications.

AAll users have their own active configuration.

Users share the same active configuration; private mode only applies to their *candidate* configuration, not the active one.

BAll users have their own private candidate configuration.Correct

When a user enters `configure private`, they create a private copy of the current active configuration, which serves as their isolated candidate configuration. Other users also operate on their own private candidate configurations, ensuring no immediate conflicts.

CWhen a user commits, all nonconflicting changes made by all users are committed.

This statement describes shared configuration mode behavior (if no conflicts), not private mode; in private mode, only the current user's changes are committed.

DWhen a user commits, only the user's own changes are committed.Correct

In private configuration mode, when a user issues the `commit` command, only the changes they have made in their private candidate configuration are merged with the active configuration. This prevents unintended commits of other users' work.
