The maintenance schedule can be set to which value?

• A. Calendar
• B. Repeating
• C. Time window
• D. Duration

Answer: (D)

In a maintenance schedule, the important setting is the duration—the amount of time allocated for the maintenance activity. This defines how long the maintenance window lasts and how much time the system should reserve for the work, which is essential for planning technician availability and avoiding conflicts with other tasks. The other options control when or how often maintenance can occur rather than how long it takes: a calendar setting fixes specific dates, a repeating setting defines recurrence, and a time window sets when the work can start within a broader period. Thus, the duration is the appropriate value to configure for the length of the maintenance window.
