Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 270

Which encryption algorithm is used for encrypting SD-WAN data plane traffic?

Answer options

• A. AES-256 GCM
• B. Triple DES
• C. AES-128
• D. IPsec

Correct answer: A

Explanation

AES-256 GCM is the encryption standard used for securing SD-WAN data plane traffic due to its strong security and efficiency. Triple DES and AES-128 are considered less secure compared to AES-256, and while IPsec is a protocol suite that can use various encryption algorithms, it is not an encryption algorithm itself.
