After making a configuration change on the NIOS Grid, you are prompted to restart services. What option provides the least service disruption?

Comprehensive and Detailed In-Depth

Restarting services post-change (e.g., DNS zone update) requires minimizing downtime:

B: “Restart if needed” checks if a restart is required per member, and “sequentially” staggers restarts

(e.g., passive HA nodes first), ensuring continuous service. Least disruptive. Correct.

A: Simultaneous force restart stops all services at once—maximum disruption. Incorrect.

C: GM-only restart ignores other members needing updates, incomplete. Incorrect.

D: HA members only misses single nodes or GM, partial solution. Incorrect.

Practical Example: In an INE lab, you’d select sequential restart after a DHCP range change, monitor

client connectivity, and troubleshoot minimal impact.
