PCNSE Manage, Monitor and Operate Practice Question
An administrator receives an alert that a firewall's disk usage is at 85%. The administrator wants to reduce disk usage by automatically deleting older log files. Which action should be taken?
⚠ Common exam trap
A common mix-up: candidates confuse 'adding external storage' (Option A) as a solution for disk usage, but the question specifically asks for automatic deletion of older logs, not just expanding capacity.

Correct answer & explanation
✓
Configure log export and auto-deletion in Log Settings
The firewall's log settings allow administrators to configure automatic log export and auto-deletion policies. By enabling log export to an external server (e.g., syslog) and setting a retention period or disk usage threshold, the firewall will automatically purge older log files when disk usage reaches a specified limit, such as 85%. This directly addresses the need to reduce disk usage without manual intervention or disabling logging.
