NSE7 Advanced Threat Protection Practice Question
Which FortiGate security feature can reconstruct files to remove potentially malicious content while preserving the file's usability?
⚠ Common exam trap
Candidates often confuse FortiSandbox's detection capabilities with CDR's proactive sanitization, mistakenly thinking sandboxing can reconstruct files when it only analyzes and blocks them.

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
✓
Content Disarm and Reconstruction
Content Disarm and Reconstruction (CDR) is the correct answer because it actively removes potentially malicious content—such as macros, scripts, or embedded objects—from files (e.g., Office documents, PDFs) and then reconstructs a clean, usable version. Unlike detection-based approaches, CDR eliminates threats by sanitizing the file structure itself, ensuring the file remains functional for the end user while blocking exploits.
