Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Delete all log entries older than 24 hours to save space
Why it's wrong here

Why this is correct
Cross-log correlation is vital to see the full attack path.

Why it's wrong here

Ensure log files have not been tampered with using checksums
