220-1102 PC Security Issue Remediation Practice Question
This 220-1202 practice question tests your understanding of pc security issue remediation. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 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?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
BitLocker Drive Encryption
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.
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.
✗
Windows Defender Firewall
Why it's wrong here
Firewall protects network traffic but does not encrypt stored data.
✗
User Account Control (UAC)
Why it's wrong here
UAC prevents unauthorized system changes but does not protect data if the drive is removed.
✓
BitLocker Drive Encryption
Why this is correct
BitLocker encrypts the drive, making data unreadable without the key, ideal for lost or stolen devices.

✗
Windows Hello for Business
Why it's wrong here
Windows Hello provides biometric authentication but does not encrypt the drive.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between authentication/access control features (like UAC or Windows Hello) and data-at-rest encryption (BitLocker), leading candidates to choose a security feature that protects the system while running rather than protecting data when the device is physically compromised.
Detailed technical explanation
How to think about this question
BitLocker uses the TPM (Trusted Platform Module) to securely store encryption keys and can be configured with a startup PIN or USB key for pre-boot authentication. Under the hood, it encrypts the entire Windows volume using AES-128 or AES-256 with Cipher Block Chaining (CBC) or XTS mode, and the decryption key is never exposed to the operating system until the correct authentication is provided. In a real-world scenario, even if an attacker removes the hard drive and connects it to another machine, the encrypted data remains unreadable without the recovery key stored in Active Directory or Microsoft Account.
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.
