Explanation

In CUCM, time-of-day routing works by attaching a Time Schedule to a Partition - when the current time falls outside that schedule, the partition becomes inactive and CUCM skips it, routing calls to the next available partition/route pattern instead. This is why C is correct: the partition acts as the time-aware gatekeeper for route patterns within it.

Why the distractors are wrong:

• A & B are wrong because CSS (Calling Search Space) is an ordered list of partitions assigned to a device; it determines where CUCM looks, not when - you cannot apply a time schedule or time period directly to a CSS.
• D is wrong because it correctly identifies the partition but uses the wrong object - a Time Period (e.g., "Mon–Fri 8am–5pm") is a building block; you must first bundle Time Periods into a Time Schedule, then assign the schedule to the partition.
• E is wrong because route patterns have no native timetable field; time control is always enforced at the partition level, not the pattern level.

Memory tip: Think of the hierarchy as Period → Schedule → Partition. The partition is the "bouncer" - it checks the Time Schedule on the door and only lets calls in during allowed hours. CSS just tells CUCM which bouncers to visit, in order.
