EMC Proven Professional – Technology Architect — Question 22

Which protocol is most commonly used for compute-to-computer communication?

Answer options

• A. TCP/IP
• B. FC
• C. FCIP
• D. iSCSI

Correct answer: D

Explanation

The correct answer is D, iSCSI, which is specifically designed for linking data storage facilities over IP networks, making it suitable for compute-to-computer communication. While TCP/IP (A) is a fundamental protocol for network communication, it is not specific to storage. FC (B) and FCIP (C) are more specialized for Fibre Channel networks and do not serve the general purpose of compute-to-computer communication as effectively as iSCSI.
