CompTIA CASP+ (CAS-004) — Question 554

A social media company wants to change encryption ciphers after identifying weaknesses in the implementation of the existing ciphers. The company needs the new ciphers to meet the following requirements:

• Utilize less RAM than competing ciphers.
• Be more CPU-efficient than previous ciphers.
• Require customers to use TLS 1.3 while broadcasting video or audio.

Which of the following is the best choice for the social media company?

Answer options

Correct answer: C

Explanation

ChaCha20-Poly1305 is the best choice as it is designed to be more efficient in both CPU usage and RAM compared to other ciphers, particularly in high-performance environments like streaming. The other options, while secure, do not meet the requirements for efficiency and resource usage as effectively as ChaCha20-Poly1305 does.
