350-701 Endpoint Protection and Detection Practice Question
This 350-701 practice question tests your understanding of endpoint protection and detection. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 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 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.
Option B is correct because setting File Reputation to 'Block' would have prevented execution of 'Unknown' files like invoice.exe. However, this might block legitimate unknown files. Option A (blocking USB execution) is too restrictive. Option C (enabling more exploit prevention rules) would not have stopped this file because it was malware, not an exploit. Option D (adding file hash to blacklist) is reactive and not proactive.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Block all execution of applications from removable media via Group Policy.
Why it's wrong here
Overly restrictive; impacts legitimate use.
✗
Enable all Exploit Prevention rules, including those for script-based attacks.
Why it's wrong here
The file was not an exploit; it was malware.
✗
Add the SHA256 hash of 'invoice.exe' to the global blacklist.
Why it's wrong here
Only blocks that specific variant, not future unknown malware.
✓
Change the File Reputation setting to 'Block' for files with 'Unknown' disposition.
Why this is correct
Prevents execution of unknown files while allowing known good files.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
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
How to think about this question
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.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
How this comes up in practice
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
Got this wrong? Here's your next step.
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 350-701 NAT questions on configuration and troubleshooting.
