Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the FMC GUI to delete unneeded packet captures and older correlation event logs or prune event data via System > Health > Monitor.
Clearing out rotated and old core dumps or troubleshooting via the system CLI using specialized scripts or purging old event data through the FMC GUI is standard. The df -h and du commands help locate space, but FMC provides specific maintenance tools to prune old events safely.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reboot the FMC appliance into single-user mode and execute a complete filesystem format on the /var partition.
Why it's wrong here
Formatting the /var partition will erase the entire Postgres database and configuration history.
- ✓
Use the FMC GUI to delete unneeded packet captures and older correlation event logs or prune event data via System > Health > Monitor.
Why this is correct
Pruning old event data or removing stale packet captures directly reduces the /var disk utilization safely.
- ✗
Navigate to System > Integration > Snort and delete all historical rule inspection data.
Why it's wrong here
Snort rule history is not stored in /var in a way that can be safely purged from integration settings.
- ✗
Run the 'rm -rf /var/sf/imagedb/*' command directly from the expert mode CLI to purge immediate image databases.
Why it's wrong here
Manually removing files from /var/sf/imagedb/ can corrupt the FMC database schema and cause total system failure.
