JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2022) — Question 15

Which three algorithms are used to encrypt IP packets? (Choose three.)

Answer options

• A. Data Encryption Standard (DES)
• B. Secure Hash Algorithm (SHA) - 1
• C. Message Digest 5 (MD5)
• D. Triple Data Encryption Standard (3DES)
• E. Advanced Encryption Standard (AES)

Correct answer: A, D, E

Explanation

The correct answers are A, D, and E because Data Encryption Standard (DES), Triple Data Encryption Standard (3DES), and Advanced Encryption Standard (AES) are all symmetric encryption algorithms used for securing IP packets. On the other hand, Secure Hash Algorithm (SHA) - 1 and Message Digest 5 (MD5) are hashing algorithms, which do not provide encryption.
