Check Point Certified Security Administrator (CCSA) R80 — Question 176

Which of the following uses the same key to decrypt as it does to encrypt?

Answer options

• A. Asymmetric encryption
• B. Dynamic encryption
• C. Certificate-based encryption
• D. Symmetric encryption

Correct answer: D

Explanation

The correct answer is D, Symmetric encryption, because it employs the same key for both encryption and decryption. In contrast, A (Asymmetric encryption) uses a pair of keys, B (Dynamic encryption) refers to varying encryption methods, and C (Certificate-based encryption) involves using certificates rather than a single key.
