Which command should be used to ensure changes are logged for SecurityTeam on a Junos OS device?

The correct command for ensuring that changes are logged for a specific user, in this case, SecurityTeam, on a Junos OS device is related to the configuration of syslog, which is responsible for logging events and changes.

Using the command structure for syslog, it sets up a specific logging mechanism that records changes made by the user. In this context, "set system syslog user SecurityTeam change-log" effectively directs the system to log all changes made by the SecurityTeam user into the change log, capturing modifications related to configurations, security policies, or other relevant activities performed by that user. This provides an audit trail and accountability, which is essential for security and operational integrity on network devices.

The other commands may not align correctly with the logging specifics or user-level action tracking required. This demonstrates the significance of understanding the command syntax and purpose within the Junos OS environment to manage and log user activities effectively.
