What are the three load-average time intervals shown by uptime?

• A. 0 min 1 min 5 min
• B. 2 min 4 min 8 min
• C. 1 sec 5 sec 15 sec
• D. 1 min 5 min 15 min

Answer: (D)

Uptime shows three load averages, each representing a different time window: the last 1 minute, the last 5 minutes, and the last 15 minutes. These numbers reflect the average number of processes in the run queue or currently running, not a percentage of CPU usage. The order is fixed from shortest to longest window, giving you a quick sense of current activity and how it’s trending over short and longer periods.

This is why the correct set is the 1-minute, 5-minute, and 15-minute intervals. The other options mix in nonstandard time units or incorrect windows, which isn’t how uptime reports load averages.
