Quick Answer
The answer is Automation Stitch. This is the correct choice because an automation stitch on FortiGate allows you to automatically block an IP from an IPS anomaly by linking a detected event—such as the tcp_syn_flood entries shown in the 'diagnose ips anomaly log' output—to a triggered action, like adding the source IP to a threat feed or executing a firewall address block. On the Fortinet NSE 7 Advanced Security NSE7 exam, this question tests your understanding of how automation stitches bridge detection and response without manual intervention, often appearing in scenarios where you must differentiate between static firewall policies, SDN connectors, or simple log monitoring. A common trap is selecting "IPS sensor" or "DoS policy," which only detect or log anomalies but lack the automated response capability. Remember the key memory tip: "Stitch it to block it"—if you need an automatic action based on an IPS event, the automation stitch is the only feature that weaves the trigger and action together seamlessly.
This NSE7 practice question tests your understanding of advanced threat protection. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
IPS Custom Signature
Why wrong: Custom signatures detect but do not automatically block by adding to block list.
Local-in Policy
Why wrong: Local-in policy controls traffic to FortiGate itself, not automatic blocking.
IP Block List
Why wrong: IP Block List is static; automatic blocking requires a dynamic response.
Automation Stitch
Automation stitches can automate responses to events like syn flood.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Automation Stitch
Automation stitches can trigger an action (like adding the source IP to a threat feed or blocking it) based on a condition such as IPS anomaly events.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
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.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related NSE7 NAT questions on configuration and troubleshooting.
