156-315.81.20 Threat Prevention and SandBlast Practice Question
A security administrator notices that Threat Emulation is bypassing all files from a specific internal server. They want to ensure that files from this server are emulated. What is the most likely reason for the bypass, and how can it be resolved?
⚠ Common exam trap
Watch out — candidates often confuse the Threat Emulation bypass list with the general Threat Prevention exception list; the former is specific to emulation and can be source-based.
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
✓
The server is listed in the Threat Emulation bypass list; remove it from the bypass list.
The Threat Emulation bypass list allows administrators to exclude specific sources from emulation. If an internal server is in this list, its files will bypass emulation. Removing the server from the list will ensure its files are emulated. Other options involve broader exceptions or limitations that would not be server-specific.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The server's IP address is in the Threat Prevention exception list; remove it from the exception list.
Why it's wrong here
Threat Prevention exception lists are used to exclude traffic from inspection entirely. However, if the server were in the exception list, all Threat Prevention blades would bypass, not just emulation. The question specifies only emulation is bypassing, so this is less likely.
- ✗
The server is using an unsupported protocol; enable emulation for that protocol.
Why it's wrong here
Threat Emulation supports common protocols like HTTP, FTP, SMTP, etc. If the server uses an unsupported protocol, emulation would not occur, but this would be a protocol issue, not server-specific. The question implies the server is bypassed specifically, so protocol is less likely.
- ✗
The files are too large for emulation; increase the maximum file size for emulation.
Why it's wrong here
If files were too large, they would be bypassed due to size limits, but this would affect all large files, not specifically those from one server. The scenario indicates a server-specific bypass, so size limits are not the likely cause.
- ✓
The server is listed in the Threat Emulation bypass list; remove it from the bypass list.
Why this is correct
Threat Emulation has a bypass list for trusted sources. If the internal server is in this list, files from it will bypass emulation. Removing the server from the bypass list will cause its files to be emulated. This is the most likely cause for selective bypass.
