- A
Enable BitLocker Drive Encryption on the system drive.
BitLocker encrypts the entire drive, ensuring that if the laptop is stolen, the data cannot be accessed without the recovery key or TPM authentication.
- B
Set a strong BIOS/UEFI password.
Why wrong: A BIOS password prevents booting the system, but the hard drive can still be removed and accessed from another machine, leaving data vulnerable.
- C
Configure a screensaver password with a short timeout.
Why wrong: A screensaver password only protects the system when it is idle; once the laptop is stolen, the attacker can bypass this by removing the drive.
- D
Use EFS to encrypt individual files and folders.
Why wrong: EFS encrypts files at the file system level but may leave system files or unencrypted areas exposed; full disk encryption is more comprehensive for a stolen device.
220-1202 Logical Security Concepts Practice Question
This 220-1202 practice question tests your understanding of logical security concepts. 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 wants to ensure that even if a laptop is stolen, the data on the hard drive cannot be read. The laptop runs Windows 10 Pro and is used by employees who travel frequently. Which security feature should be enabled?
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
Enable BitLocker Drive Encryption on the system drive.
BitLocker Drive Encryption is the correct choice because it encrypts the entire system drive at the block level, using AES encryption (typically 128-bit or 256-bit) with a TPM (Trusted Platform Module) to protect the encryption keys. This ensures that if the laptop is stolen, the hard drive cannot be removed and read from another system, as the data remains encrypted without the correct authentication (e.g., TPM + PIN or recovery key).
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
A BIOS password prevents booting the system, but the hard drive can still be removed and accessed from another machine, leaving data vulnerable.
- ✗
Configure a screensaver password with a short timeout.
Why it's wrong here
A screensaver password only protects the system when it is idle; once the laptop is stolen, the attacker can bypass this by removing the drive.

Why it's wrong here
EFS encrypts files at the file system level but may leave system files or unencrypted areas exposed; full disk encryption is more comprehensive for a stolen device.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA A+ often tests the distinction between encryption at rest (BitLocker) and access control (BIOS password, screensaver) or partial encryption (EFS), leading candidates to choose a non-encryption option that does not protect data when the drive is physically removed.
Detailed technical explanation
How to think about this question
BitLocker uses a combination of TPM, Secure Boot, and a full-volume encryption key (FVEK) that is encrypted by a volume master key (VMK), which is further protected by TPM or a recovery key. In a real-world scenario, if a laptop is stolen while in sleep mode, BitLocker with TPM-only protection might still allow data access if the attacker can resume the session; thus, organizations often enforce additional pre-boot authentication like a PIN or USB key to mitigate this risk.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
