A. B. C. D.B
Option D is the correct answer for this question. The command "show system switchover" is used to display the current state of the graceful Routing Engine switchover feature. The output of this command on the master Routing Engine will show "Graceful switchover: On" if the feature is enabled. This means that if the master Routing Engine were to fail, the backup Routing Engine would take over without any disruption in service, resulting in minimum downtime for the users.
Option A and Option C are both showing the output of the "show system snapshot" command. This command displays information about the system snapshots, which are backups of the entire file system. While creating and maintaining system snapshots is important for disaster recovery, it is not directly related to enabling graceful Routing Engine switchover.
Option B is showing the output of the "show system switchover" command on the backup Routing Engine. This output indicates that the system is ready for a switchover, but it does not indicate whether graceful switchover is enabled. Therefore, Option B is not the correct answer.
In summary, the correct output that accomplishes the task of enabling graceful Routing Engine switchover on a router with dual Routing Engines is:
{master} user@R1-re0> show system switchover Graceful switchover: On Configuration database: Ready Kernel database: Ready
