350-701 Endpoint Protection and Detection Practice Question
A security analyst is investigating a malware incident on an endpoint protected by Cisco AMP for Endpoints. The Device Trajectory shows that a file named 'invoice.exe' was detonated from a USB drive. The file's cloud verdict was 'Unknown' at the time of execution. The analyst sees that the file spawned multiple child processes that made outbound connections to a malicious IP. The AMP policy has 'Exploit Prevention' enabled but 'File Reputation' is set to 'Monitor' only. The analyst wants to prevent similar incidents in the future without blocking legitimate applications. Which action should the analyst recommend?
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
✓
Change the File Reputation setting to 'Block' for files with 'Unknown' disposition.
Changing the File Reputation setting to 'Block' for files with 'Unknown' disposition would prevent unknown files like 'invoice.exe' from executing in the future, while still allowing files with known good reputations. This balances security with usability. Option A (blocking all USB execution via Group Policy) is too restrictive as it would block legitimate applications from removable media. Option B (enabling all Exploit Prevention rules) targets exploit techniques, not malware executables like 'invoice.exe'. Option C (adding the hash to a global blacklist) is reactive and would only block that specific hash, not similar unknown files.
