Which statement best describes DAS relative to SAN?

• A. It offers direct attachment per server with typically lower cost per capacity.
• B. It provides centralized management across the network.
• C. It allows seamless resource sharing across servers in a network.
• D. It requires complex fabric switches for connectivity.

Answer: (A)

DAS is storage that connects directly to a single server, without a separate storage network. This simple setup keeps costs lower because you avoid the extra SAN hardware and network fabric—no fabric switches or centralized controllers required. That’s why the statement describing direct attachment per server with typically lower cost per capacity best captures how DAS compares to SAN.

In contrast, SAN is built for centralized management across a network and seamless sharing of storage resources among multiple servers, which is not inherent to DAS. Likewise, DAS does not rely on complex fabric switches to function, and its primary use is not wide-scale cross-server sharing, but direct access from a single host.
