• C
  11% (2)
• D

Explanation

For securing Azure NetApp Files and ensuring the confidentiality of data, a critical security feature is double encryption at rest. This technique involves encrypting the data twice at rest, once at the storage level using Azure's default encryption and again using NetApp's built-in encryption features such as NetApp Volume Encryption (NVE). Double encryption provides an additional layer of protection, significantly reducing the risk of data breaches or unauthorized access. While network security groups (A) and Kerberos encryption (C) play roles in protecting network traffic and securing authentication, they do not address the need for data encryption at rest, which is critical for confidentiality. Virtual Network Encryption (B) is also related to encrypting network data but doesn't focus on encryption at rest. In highly regulated environments where data confidentiality is paramount, double encryption at rest ensures that even if one encryption layer is compromised, the data remains protected by the second encryption layer, thereby greatly enhancing security.
