What is the primary function of FortiDeceptor in a network security architecture?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.
To provide network access control for endpoints
Why wrong: That is FortiNAC's role.
To aggregate logs from multiple security devices
Why wrong: That is FortiAnalyzer's role.
To lure attackers into interacting with decoys and generate alerts
FortiDeceptor uses decoys to detect lateral movement.
To detect and block malware at the endpoint
Why wrong: That is FortiClient's role.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
To lure attackers into interacting with decoys and generate alerts
FortiDeceptor is a deception-based threat detection solution that deploys decoys (fake assets) across the network to lure attackers. When an attacker interacts with a decoy, FortiDeceptor generates a high-fidelity alert, enabling early detection of lateral movement or reconnaissance without relying on signatures.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
To provide network access control for endpoints
Why it's wrong here

To aggregate logs from multiple security devices
Why it's wrong here
That is FortiAnalyzer's role.
To lure attackers into interacting with decoys and generate alerts
Why this is correct
FortiDeceptor uses decoys to detect lateral movement.

Common exam traps
The trap here is that candidates confuse FortiDeceptor's deception-based detection with endpoint protection or log aggregation, but the exam specifically tests that its primary function is to lure attackers into interacting with decoys and generate alerts.
Detailed technical explanation
FortiDeceptor uses a distributed architecture where decoys emulate real services (e.g., SMB, RDP, SSH) and are placed in the same VLAN or subnet as production assets. When an attacker performs a scan or connection attempt to a decoy IP, the Deceptor triggers an alert with the attacker's source IP, timestamp, and protocol details, enabling immediate containment via integration with FortiGate or FortiSIEM. In a real-world scenario, a compromised host performing ARP scans will hit a decoy IP, and FortiDeceptor can automatically create a firewall rule to block the attacker's IP.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
