Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) — Question 297

What is an advantage of symmetric over asymmetric encryption?

Answer options

• A. It is a faster encryption mechanism for sessions.
• B. A one-time encryption key is generated for data transmission.
• C. A key is generated on demand according to data type.
• D. It is suited for transmitting large amounts of data.

Correct answer: A

Explanation

Symmetric encryption is generally faster than asymmetric encryption because it uses the same key for both encryption and decryption, making the process more efficient. The other options describe features of encryption types but do not highlight the speed advantage of symmetric encryption.
