Quick Answer
The answer is to configure log archiving to an external storage. This action immediately frees up disk space on the FortiAnalyzer while preserving all historical log data for compliance or forensic needs, because archiving moves older logs off the local disk to a remote server or cloud target without deleting them. On the Fortinet NSE 7 Advanced Security NSE7 exam, this scenario tests your understanding of log lifecycle management and the trade-off between storage pressure and data retention—a common trap is choosing to delete old logs (which loses evidence) or to compress logs (which offers only marginal, temporary relief). Remember the mnemonic "Archive, Don't Annihilate": archiving preserves audit trails for post-incident analysis, whereas deletion or compression can violate retention policies or fail to reclaim sufficient space.
This NSE7 practice question tests your understanding of troubleshooting and diagnostics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You receive an alert that FortiAnalyzer log disk usage is at 95%. Which action should you take to immediately free up space without losing important logs?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Delete all logs older than 30 days
Why wrong: This deletes logs permanently.
Enable log compression
Why wrong: Log compression saves space but does not free existing space.
Configure log archiving to an external storage
Archiving moves old logs off the device.
Increase log disk quota
Why wrong: This does not free space; it only allows more usage.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Configure log archiving to an external storage
Option C is correct because archiving old logs to external storage is the best practice to free space while preserving logs. Option A would lose logs. Option B is not a standard feature. Option D is temporary.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the NSE7 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
