Which of the following allows you to provide security to the data contained in a storage array?

Trunking
LUN masking
LUN provisioning
Multipathing

The correct answer is: LUN masking

LUN masking is a critical security mechanism used within storage arrays to control which hosts or servers can access specific Logical Unit Numbers (LUNs) in a storage environment. By implementing LUN masking, an administrator can restrict access to sensitive data, ensuring that only authorized systems have visibility or rights to specific volumes. This serves to protect the data from unauthorized access, which is essential in environments where sensitive information is stored. In contrast, trunking pertains to combining multiple network connections to enhance bandwidth but does not directly contribute to data security. LUN provisioning refers to the allocation of storage resources to different applications or users, not specifically addressing secure access. Multipathing is a technique used to provide redundancy and load balance across multiple paths to storage, which improves availability but does not inherently secure the data itself. Therefore, LUN masking is the appropriate choice for providing security to the data in a storage array.
