Dell EMC Associate – Information Storage and Management v4 — Question 51

What is an accurate statement about scale-out NAS?

Answer options

• A. Creates a different file system for each node in the cluster
• B. Stripes data across nodes with mirror or parity protection
• C. Supports only data replication for protecting data
• D. Pools node resources in a cluster to work as multiple NAS devices

Correct answer: B

Explanation

The correct answer is B because scale-out NAS systems distribute data across multiple nodes while employing mirroring or parity for redundancy. Option A is incorrect as scale-out NAS typically uses a unified file system across nodes, while C is wrong since it also allows for other forms of protection besides replication. Option D is partially true but does not capture the data protection aspect that is crucial in defining scale-out NAS.
