FC0-U71 Practice Question: A user wants to prevent unauthorized access to…
A user wants to prevent unauthorized access to their laptop if stolen. Which is the best method?
⚠ Common exam trap
Candidates often confuse authentication (password) with encryption (BitLocker), assuming a strong password alone protects data against physical theft, but it only protects against casual login attempts, not direct disk access.

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
BitLocker is a full-disk encryption feature built into Windows that encrypts the entire drive, making data inaccessible without the decryption key. If the laptop is stolen, the thief cannot read any files even if they remove the hard drive and connect it to another system. This directly prevents unauthorized access to data, unlike other options that only protect against network or software threats.
