The answer is to enable BitLocker on the system drive, as this is the most appropriate remediation for protecting data on a stolen laptop running Windows 11 Pro. BitLocker is a native full-disk encryption feature that encrypts the entire drive, including the operating system, applications, and all user data, rendering it unreadable without the recovery key or TPM authentication—even if the drive is physically removed and attached to another computer. On the CompTIA A+ Core 2 220-1202 exam, this question tests your understanding of data destruction and physical security controls, often appearing as a scenario where the thief bypasses the login screen but cannot access the encrypted data. A common trap is confusing BitLocker with EFS (Encrypting File System), which only encrypts individual files, not the whole drive. Remember the mnemonic: “BitLocker blocks the boot, EFS only encrypts the file.”
220-1102 PC Security Issue Remediation Practice Question
This 220-1202 practice question tests your understanding of pc security issue remediation. 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.
A small business owner wants to ensure that if a laptop is stolen, the data on the drive cannot be read. The laptop runs Windows 11 Pro. What is the most appropriate remediation?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable BitLocker on the system drive
BitLocker is the native full-disk encryption feature in Windows 11 Pro that encrypts the entire system drive, including the operating system, applications, and all user data. If the laptop is stolen, the data on the drive remains unreadable without the recovery key or TPM authentication, even if the drive is removed and attached to another computer. This directly addresses the requirement to prevent data access after theft.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Set a strong BIOS password
Why it's wrong here
A BIOS password prevents booting but the drive can still be removed and read in another machine.
✓
Enable BitLocker on the system drive
Why this is correct
BitLocker encrypts the entire drive, rendering data inaccessible without the key, even if the drive is removed.
Related concept
Read the scenario before looking for a memorised answer.
✗
Install an antivirus with anti-theft features
Why it's wrong here
Antivirus software does not encrypt the drive; it may have tracking features but does not protect data if the drive is removed.
✗
Use a cloud backup service
Why it's wrong here
Cloud backup ensures data recovery but does not prevent access to data on the stolen drive.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse a BIOS password with drive encryption, thinking it secures the data, but BIOS passwords only control boot access and do not protect against physical drive removal and forensic analysis.
Detailed technical explanation
How to think about this question
BitLocker uses AES encryption (128-bit or 256-bit) in XTS or CBC mode, with the encryption keys stored in the TPM (Trusted Platform Module) or as a recovery key. In a real-world scenario, if the laptop is stolen and the thief removes the SSD, they cannot decrypt the data without the TPM or recovery key, even if they bypass the Windows login screen. This is fundamentally different from file-level encryption or EFS, which only protects specific files and not the entire volume.

→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.

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.

Variation 1. A technician is configuring a new Windows 10 workstation for a remote employee who will handle sensitive customer data. Which security feature should be enabled to ensure that if the laptop is lost, the data remains protected?
easy
A.Windows Defender Firewall
B.User Account Control (UAC)
✓ C.BitLocker Drive Encryption
D.Windows Hello for Business
Why C: BitLocker Drive Encryption (C) is the correct choice because it provides full-disk encryption using AES encryption algorithms, ensuring that if the laptop is lost or stolen, the sensitive customer data remains inaccessible without the recovery key or TPM authentication. This directly addresses the requirement to protect data at rest on a lost device.
