CompTIA Network+ (N10-008) — Question 86

Which of the following attacks encrypts user data and requires a proper backup implementation to recover?

Answer options

• A. DDoS
• B. Phishing
• C. Ransomware
• D. MAC spoofing

Correct answer: C

Explanation

Ransomware is the correct answer because it specifically targets user data by encrypting it and demands a ransom for decryption, making backups essential for recovery. DDoS attacks aim to overwhelm services, phishing scams deceive users into revealing personal information, and MAC spoofing involves altering MAC addresses, none of which directly encrypt data like ransomware does.
