The correct answer is to remove the USB drive and use a different approved method of file transfer. This is because the security policy mandates that all external media must be scanned for malware before use, and a hardware write-protect switch prevents the antivirus scan from writing detection signatures or quarantining threats, making the scan incomplete and non-compliant. On the Cisco CyberOps Associate 200-201 exam, this scenario tests your understanding of USB media scanning policy compliance and the principle that policy overrides convenience—a common trap is choosing to bypass the scan or disable write-protection, which violates the policy outright. Remember the memory tip: “No scan, no use—find another fuse.”
200-201 Security Policies and Procedures Practice Question
This 200-201 practice question tests your understanding of security policies and procedures. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
An organization's security policy mandates that all external media (USB drives, external hard drives) must be scanned for malware before use. An employee inserts a USB drive to transfer a presentation for a meeting. The employee runs the antivirus scan, but it fails to complete because the USB drive has a hardware write-protect switch. The employee is in a hurry. What should the employee do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Remove the USB drive and use a different approved method of file transfer.
Option C is correct because if the scan cannot be performed, the USB should not be used; using an alternative method complies with policy. Option A may still not allow a proper scan; Option B violates policy; Option D is not a substitute for scanning.
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.
✗
Manually check each file for suspicious extensions.
Why it's wrong here
Manual inspection is not a substitute for automated scanning.
✓
Remove the USB drive and use a different approved method of file transfer.
Why this is correct
This complies with policy by avoiding an unscanned medium.
Related concept
Static NAT maps one inside address to one outside address.
✗
Disable write protection and rescan.
Why it's wrong here
Write protection may be there for a reason; disabling it could allow malware to infect the USB.
✗
Proceed with the file transfer since the scan failed due to hardware issue.
Why it's wrong here
This directly violates the policy.
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 200-201 NAT questions on configuration and troubleshooting.
