SNIA Certified Storage Networking Expert (CSNE) — Question 6

What is the purpose of a host bus adapter (НВА)?

Answer options

• A. to connect a switch port to front end storage
• B. to provide host backups to tape media
• C. to connect a host to a switch
• D. to use a host CPU to interface with storage controllers C

Correct answer:

Explanation

The correct answer is C, as a host bus adapter (HBA) is specifically designed to facilitate the connection between a host and a switch, enabling communication with storage networks. Option A is incorrect because it describes a connection to storage, not specifically to a host. Option B is not accurate as HBAs do not handle backups, and Option D misrepresents the function by implying direct storage controller interfacing without the switch component.
