Which configuration edit mode allows only one user to modify the global candidate configuration?
Correct Answer: D
In Nokia SR OS, theMD-CLIprovides multiple configuration edit modes to allow different types of user interaction with the configuration system:
* Private modeallows multiple users to create individual configuration candidates, which are then merged with the global candidate during commit.
* Global modeenables multiple users to edit the same candidate configuration at the same time, with a shared commit session.
* Read-only modeallows the user to view the configuration without making changes.
* Exclusive moderestricts access to the global candidate configuration such thatonly one user at a time can enter and make changes. This prevents conflicts and is useful in environments where strict control over configuration changes is necessary.
Therefore, the correct answer isExclusive mode, as itexclusively locks access to the global candidatefor a single user.
