NSE7 Advanced Threat Protection Practice Question
A FortiGate administrator runs the following CLI command: 'diagnose ips anomaly log' The output shows numerous 'tcp_syn_flood' events from a single source IP. To mitigate this, the administrator wants to block the source IP automatically. Which feature should be used?
⚠ Common exam trap
Candidates often confuse the IP Block List (a static or manually managed list) with the Automation Stitch (the automated engine that can dynamically add entries to that list based on events), leading them to select Option C instead of D.

Correct answer & explanation
✓
Automation Stitch
The 'diagnose ips anomaly log' command displays anomalies detected by the FortiGate's DoS (Denial of Service) sensor, such as TCP SYN flood events. An Automation Stitch (Option D) is the correct feature to automatically block the source IP because it can trigger a 'Block IP' action based on a 'IPS Anomaly' event, creating an automated response without manual intervention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
IPS Custom Signature
Why it's wrong here
Custom signatures detect but do not automatically block by adding to block list.
- ✗
Local-in Policy
Why it's wrong here
Local-in policy controls traffic to FortiGate itself, not automatic blocking.
- ✗
IP Block List
Why it's wrong here
IP Block List is static; automatic blocking requires a dynamic response.
- ✓
Automation Stitch
Why this is correct
Automation stitches can automate responses to events like syn flood.
