300-710 SNCF Management And Troubleshooting Practice Question
An FTD device managed by FMC is experiencing high CPU utilization attributed to the Snort inspection engine. The administrator wants to identify which specific intrusion rules or access control rules are consuming the most resources. Which tool or report should the administrator use?
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
✓
Access the FTD CLI and run 'system support diagnostic-cli' followed by 'show perfstats' or review the Intrusion Performance dashboard in FMC.
The Performance Statistics feature and Intrusion Event analysis in FMC help identify resource-heavy traffic and rules. Additionally, the 'Show Snort Statistics' or 'Perfstats' command via the FTD diagnostic CLI provides real-time rule processing metrics.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Run a packet capture on the management interface (eth0) with a BPF filter for CPU interrupts.
Why it's wrong here
Capturing eth0 traffic will not reveal internal Snort thread CPU consumption.
- ✓
Access the FTD CLI and run 'system support diagnostic-cli' followed by 'show perfstats' or review the Intrusion Performance dashboard in FMC.
Why this is correct
FMC Intrusion Performance dashboards and CLI perfstats provide granular details on rule processing overhead.
- ✗
Navigate to Analysis > Datastores > Packet Trace and export the raw CPU register dump.
Why it's wrong here
There is no raw CPU register dump export tool named Packet Trace in the FMC menus.
- ✗
Check the Interfaces > Counters page in the Cisco Integrated Management Controller (CIMC).
Why it's wrong here
CIMC shows hardware sensor data, not Snort inspection engine rule processing metrics.
