Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 13

Which algorithm provides encryption and authentication for data plane communication?

Answer options

• A. AES-GCM
• B. SHA-96
• C. AES-256
• D. SHA-384

Correct answer: A

Explanation

AES-GCM is a mode of operation that combines the Advanced Encryption Standard (AES) with Galois/Counter Mode (GCM) to provide both encryption and authentication. In contrast, SHA-96, SHA-384, and other SHA variants are cryptographic hash functions that do not offer encryption capabilities, making them unsuitable for data plane communication that requires both security measures.
