When a user enters private configuration mode by typing "configure private," it means that the user creates a private configuration that is separate from the active configuration. This private configuration is stored separately and is not visible to other users.

The following two statements apply when a user has entered private configuration mode:

  1. All users have their own active configuration. This statement is not correct. When a user enters private configuration mode, only that user has their own private configuration. Other users still share the same active configuration.

  2. All users have their own private candidate configuration. This statement is correct. When a user enters private configuration mode, that user creates their own private candidate configuration. This private candidate configuration is separate from the shared candidate configuration and is not visible to other users.

When a user enters private configuration mode, any changes they make are made to their private candidate configuration. These changes do not affect the shared candidate configuration or the active configuration. When the user is ready to commit their changes, they must first exit private configuration mode by typing "exit private" and then commit their changes.

The following two statements are related to committing changes made in private configuration mode:

  1. When a user commits, all nonconflicting changes made by all users are committed. This statement is not correct. When a user commits their changes, only their own changes are committed. Any conflicting changes made by other users will cause the commit to fail.

  2. When a user commits, only the user's own changes are committed. This statement is correct. When a user commits their changes, only their own changes are committed. The shared candidate configuration is updated with the user's changes, and the changes become part of the active configuration when the commit is successfully completed.

In summary, when a user enters private configuration mode, they create their own private candidate configuration. Only the user has access to this private configuration, and any changes they make are not visible to other users. When the user is ready to commit their changes, only their own changes are committed, and any conflicting changes made by other users will cause the commit to fail.
