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 requires that all data at rest on laptops be encrypted. An employee reports that their laptop was stolen. Which control would most likely prevent data exposure?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Full disk encryption
Option B is correct because full disk encryption ensures data cannot be read from the drive. Option A is wrong because remote wipe requires network connectivity. Option C is wrong because screen lock only protects while unattended. Option D is wrong because biometric authentication does not encrypt data.
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.
✗
Remote wipe
Why it's wrong here
Remote wipe requires the laptop to be connected to the network, which may not be possible.
✗
Biometric authentication
Why it's wrong here
Biometrics control access but do not encrypt stored data.
✓
Full disk encryption
Why this is correct
Full disk encryption encrypts all data on the drive, preventing access even if the drive is removed.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Screen lock with password
Why it's wrong here
Screen lock only protects when the device is unattended but does not encrypt data at rest.
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.

What is the correct answer to this question?
The correct answer is: Full disk encryption — Option B is correct because full disk encryption ensures data cannot be read from the drive. Option A is wrong because remote wipe requires network connectivity. Option C is wrong because screen lock only protects while unattended. Option D is wrong because biometric authentication does not encrypt data.

Are there clue words in this question I should notice?
Yes — watch for: "most likely". Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
