Comprehensive and Detailed In-Depth Explanation: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.References:Infoblox NIOS Administrator Guide
