Configuring Exclusive Edit Mode

C

The correct answer is C. configure exclusive.

In Junos, there are different modes that control access to the configuration.

• configure batch: This mode is used to make a series of changes to the configuration without committing them until all changes are completed. It is useful when making multiple changes to the configuration, and it is necessary to ensure that all changes are correct before committing them. However, it does not restrict access to the configuration, and multiple users can edit the configuration at the same time.

• configure private: This mode is used to create a private copy of the configuration for a specific user. The user can make changes to the configuration without affecting the running configuration, and the changes are not visible to other users. However, other users can still access the configuration and make changes.

• configure exclusive: This mode is used to allow only one user to edit the configuration at a time. When a user enters exclusive mode, the system reserves the configuration database exclusively for that user, and no other user can make changes to the configuration until the user exits exclusive mode. This mode is useful when it is essential to prevent multiple users from making changes to the configuration simultaneously and avoid conflicts.

• configure dynamic: This mode is used to make changes to the configuration in real-time, without the need to commit them. This mode is typically used for troubleshooting and testing, as it allows users to make changes to the configuration and see the results immediately. However, the changes are not persistent and will be lost when the system is rebooted.

In summary, the configure exclusive mode is used to allow only one person to edit the configuration at a time, making it a useful mode to prevent multiple users from making conflicting changes to the configuration.
