NSE4 High Availability and Diagnostics Practice Question
A network admin receives an alert that the FortiGate disk logs are no longer being written. The admin checks the disk status and sees that the disk is full. However, the admin needs to preserve the logs for compliance purposes. Which action should the admin take to continue logging while preserving the existing logs?

Correct answer & explanation
✓
Configure log upload to FortiAnalyzer and manually archive current logs, then clear the local disk
The correct action is to configure log upload to FortiAnalyzer and manually archive the current logs, then clear the local disk. This preserves the logs for compliance by offloading them to an external server, while freeing up disk space to allow new logging to continue. Other options are incorrect: increasing the disk quota does not solve the full issue, deleting logs loses compliance data, and compression alone may not free enough space immediately.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure log upload to FortiAnalyzer and manually archive current logs, then clear the local disk
Why this is correct
Uploading existing logs to FortiAnalyzer preserves them off-device, then clearing the local disk frees space for continued logging. This is the proper workflow.
- ✗
Increase the log disk quota to allow more logs
Why it's wrong here
If the disk is full, increasing quota won't help; the physical disk space is exhausted.
- ✗
Delete all logs from the disk and restart logging
Why it's wrong here
This destroys existing logs, which the admin needs to preserve.
- ✗
Compress the existing log files and set a higher compression level for future logs
Why it's wrong here
Compression may free some space, but if disk is completely full, compression may not be possible without first freeing space. Also, compression alone may not be sufficient and can cause performance impact.
