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 all company laptops have their hard drives encrypted in case of theft. The laptops run Windows 10 Pro. Which technology should the technician enable to meet this requirement?
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 (option C) is the correct technology because it provides full-disk encryption for Windows 10 Pro, ensuring that all data on the laptop's hard drive is encrypted at rest. This protects against data exposure if the device is stolen, as the drive cannot be accessed without the decryption key (e.g., a PIN, USB key, or TPM-based authentication). BitLocker is built into Windows 10 Pro and is specifically designed for whole-drive encryption, meeting the requirement for all company laptops.
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.
✗
EFS (Encrypting File System)
Why it's wrong here
EFS encrypts individual files and folders, not the entire drive, and is not as robust against physical theft as full-disk encryption.
✗
Windows Defender Antivirus
Why it's wrong here
Windows Defender is an antivirus program, not an encryption tool.
✓
BitLocker Drive Encryption
Why this is correct
BitLocker provides full-disk encryption for Windows 10 Pro and Enterprise, meeting the requirement for data protection on lost or stolen laptops.

✗
TPM (Trusted Platform Module)
Why it's wrong here
TPM is a hardware security chip that can support BitLocker, but it is not an encryption tool itself; it stores encryption keys securely.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse EFS (file-level encryption) with full-disk encryption, or they mistakenly think TPM alone provides encryption, when in fact TPM is merely a key storage and attestation component that requires BitLocker to enable drive encryption.
Detailed technical explanation
How to think about this question
BitLocker uses AES encryption (typically 128-bit or 256-bit) in XTS or CBC mode to encrypt the entire volume, including the operating system, page files, and hibernation files. It leverages the TPM to validate system integrity at boot and release the encryption key only if the boot components are unaltered, preventing offline attacks such as boot-sector manipulation. In a real-world scenario, if a laptop is stolen, BitLocker with TPM ensures that even if the attacker removes the hard drive and connects it to another machine, the data remains inaccessible without the recovery key.

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.
