To meet the requirement of restarting a group of Server OS VDA machines weekly on weekends and also daily for a subset during non-peak hours, which setting must be changed from its default value?

• A. Restart duration
• B. Weekday and weekend hours
• C. Peak and non-peak hours
• D. Tag restrictions

Answer: (D)

The key idea is targeting which machines get restarted. In Citrix Virtual Apps and Desktops, actions like restart are applied to machines that match certain tags, controlled by tag restrictions. To restart a specific group of Server OS VDA machines weekly on weekends and also a subset daily during non‑peak hours, you must include the relevant machine tags in the tag restrictions (or remove restrictions that block them). This makes the restart task apply only to those tagged machines, exactly matching the requested scope.

Restart duration affects how long the restart process is allowed to run, not which machines are included. Scheduling windows (weekday/weekend hours or peak/non-peak hours) control when restarts happen, but without the correct tag restrictions, the target group won't be selected. Hence, adjusting tag restrictions is the necessary change.
