CCNA: Cisco Certified Network Associate — Question 594

What is a characteristic of RSA?

Answer options

• A. It uses preshared keys for encryption.
• B. It is an asymmetric encryption algorithm.
• C. It is a symmetric decryption algorithm.
• D. It requires both sides to have identical keys for encryption.

Correct answer: B

Explanation

The correct answer is B because RSA is specifically designed as an asymmetric encryption algorithm, which utilizes a pair of keys: a public key for encryption and a private key for decryption. Options A, C, and D are inaccurate because they describe symmetric encryption characteristics, which do not apply to RSA.
