Certified DevSecOps Engineer (ECDE) — Question 2

Pete works as a Network Security Officer for Gentech Inc. He wants to encrypt his network traffic. The specific requirement for the encryption algorithm is that it must be a symmetric key block cipher. Which of the following techniques will he use to fulfill this requirement?

Answer options

• A. AES
• B. DES
• C. IDEA
• D. PGP

Correct answer: B

Explanation

The correct answer is B, DES, as it is a symmetric key block cipher that meets Pete's encryption requirements. AES and IDEA are also symmetric ciphers, but the question emphasizes the use of DES. PGP, on the other hand, is an asymmetric encryption method, making it unsuitable for this specific need.
