The Junos OS network operating system uses a candidate configuration, which is a temporary configuration that allows administrators to test, modify, and stage configuration changes before they become active. Here are the three true statements regarding the candidate configuration:
A. The candidate configuration is a temporary configuration that might become the active configuration.
This statement is true. The candidate configuration is a temporary configuration that reflects the desired changes that an administrator wants to make. When an administrator commits the candidate configuration, it can become the new active configuration if the changes are valid and do not conflict with the existing active configuration.
B. A candidate configuration is initially populated with the configuration currently active on the system.
This statement is also true. When a user starts to configure the system, the system copies the active configuration to the candidate configuration. This way, the user can modify the candidate configuration without affecting the active configuration.
C. Changes to the candidate configuration take effect immediately.
This statement is false. Changes to the candidate configuration do not take effect immediately. The changes are staged in the candidate configuration until the user commits them. The user can review and test the changes in the candidate configuration before committing them to the active configuration.
D. The candidate configuration becomes the active configuration after a system reboot.
This statement is false. The candidate configuration does not become the active configuration after a system reboot. Instead, the system loads the saved active configuration from the configuration database and applies it to the system. To make the changes in the candidate configuration permanent, the user must commit the changes to the active configuration.
E. The configure private command allows concurrent editing of a candidate configuration by multiple users.
This statement is also false. The configure private command allows a user to edit a private copy of the configuration that is not visible to other users. This way, multiple users can work on different parts of the configuration simultaneously without affecting each other. However, the configure private command does not allow concurrent editing of the candidate configuration by multiple users.
