How is used space determined?

Used space in a storage system refers to the total amount of space that is currently occupied by files and data, which includes archives, analytics logs, and system files. The correct choice indicates that to determine the used space, you need to account for all these elements together.

When adding the archive and analytics logs along with all system files, it provides a comprehensive view of how much storage is actively utilized in the system. This includes not only operational logs and data that are in use but also older data that might still occupy space within the storage infrastructure.

When evaluating other potential methods, recording historical data trends primarily focuses on observing changes over time rather than quantifying actual storage use at a given moment. Calculating the number of active sessions involves transient data that does not give a full picture of long-term storage use. Finally, subtracting unused space from total storage doesn't effectively represent the total space the active logs and files occupy, as it only looks at what isn't being used without directly measuring the actual used components.
