CompTIA Security+ (SY0-401) — Question 14

A server administrator discovers the web farm is using weak ciphers and wants to ensure that only stronger ciphers are accepted. Which of the following ciphers should the administrator implement in the load balancer? (Choose Two)

Answer options

• A. SHA-129
• B. DES
• C. MD5
• D. RC4
• E. CRC-32

Correct answer: A, D

Explanation

The correct answers are A and D because SHA-129 and RC4 represent stronger cipher options compared to the others listed. DES, MD5, and CRC-32 are considered weak and vulnerable to attacks, making them unsuitable for secure communications.
