From the CLI, the administrator must show the status of the DNS processes every 10...

Comprehensive and Detailed In-Depth Explanation:Monitoring DNS processes via NIOS CLI requires the show process command:

Goal:Display DNS status every 10 seconds for 60 seconds (6 refreshes).

Actual Command:NIOS CLI doesn’t have a single command with “refresh” and “run for” syntax as listed. Closest is:

show process dns (displays DNS service status).

No native auto-refresh exists—admins use external tools (e.g., watch -n 10 "show process dns") or repeat manually.

Options:

A:“refresh 10 run for 60” isn’t valid syntax. Incorrect.

B:“refresh 10” isn’t supported, but manually running show process dns and repeating (e.g., via script or Enter) is closest. Incorrect syntax but feasible intent.

C/D:“screen refresh” isn’t NIOS CLI—sounds like UNIX screen. Incorrect.

Workaround:SSH with while true; do show process dns; sleep 10; done and Ctrl+C after 60s.

Practical Example:In an INE lab, you’d script this to monitor DNS during a failover, troubleshooting service uptime.
