Final answer:
Automatic baselines are available 24 hours after the application or service has been detected.
Step-by-step explanation:
The correct answer is 24 hours. Automatic baselines become available 24 hours after the application or service has been detected.
When treating it as if it is only on for 12 hours, the baseline would still be available after 24 hours. Operating at half-power for 24 hours would also yield the same result.
For example, if an application or service is detected at 9:00 AM, the automatic baseline would be available at 9:00 AM the next day, which is 24 hours later.
