Which best practice ensures data security in the private cloud?

The correct answer is B. Encrypt data at rest and in transition. Encrypting data both at rest and in transit is the foundational best practice for protecting data confidentiality in a private cloud environment.

Why each option

Encrypting data both at rest and in transit is the foundational best practice for protecting data confidentiality in a private cloud environment.

AUse IPsec for communication between unsecured network connection

IPsec secures communication over unsecured network links but does not address data stored at rest, making it an incomplete data security control on its own.

BEncrypt data at rest and in transition.Correct

Encrypting data at rest protects stored data from unauthorized physical or logical access, while encrypting data in transit (using protocols like TLS or IPsec) protects data as it moves across networks. Together, these two controls address the primary attack surfaces against data confidentiality in a private cloud deployment.

CUse the same vendor for consistent encryption.

Using the same vendor does not guarantee stronger or consistent encryption - security depends on algorithm strength and proper implementation, not vendor homogeneity.

DAnonymize data ownership to comply with privacy rules.

Anonymizing data ownership is a privacy compliance technique, not an encryption or data protection control for securing data confidentiality.
