問題文

A team is deciding how long to keep operational logs. Which consideration should drive the retention period?

選択肢

1. The rate at which the application writes messages, since a chattier application needs a shorter period to stay inside the same budget.
2. The amount of free space on the log volume, because keeping logs until it is full and then discarding the oldest ones matches the retention to the capacity.
3. The default that the logging tool ships with, reflecting what most installations have found workable.
4. The longest window over which the logs are actually needed, which comes from the investigation and compliance requirements, balanced against the cost of storing them.
