Dell Technologies Proven Professional – Information Storage and Management (2023) — Question 12

What is an accurate statement about scale-out NAS?

Answer options

• A. Creates a different file system for each node in the cluster
• B. Pools node resources in a cluster to work as multiple NAS devices
• C. Increases performance and capacity by adding nodes to the cluster
• D. Supports only data replication for protecting data across the nodes

Correct answer: C

Explanation

The correct answer, C, is accurate because scale-out NAS systems improve both performance and capacity by adding more nodes. Option A is incorrect as it suggests separate file systems are created, which is not the case. Option B misrepresents the function, as scale-out NAS works as a single system rather than multiple devices. Option D is wrong because scale-out NAS can support various data protection methods beyond just replication.
