What is a connectivity rule for a host that connects to multiple Dell Unity XT systems?

Question

Options

• AThe iSCSI protocol is required when host connects to multiple arrays.
• BThe host can connect to different arrays with different protocols.
• CCNA connections to the host must be used with alternating protocols
• DThe host must connect to all the arrays using a single protocol.

• B
  93% (25)
• C
  4% (1)
• D
  4% (1)

Explanation

Option B is correct because Dell Unity XT supports multi-protocol environments - a single host can connect to different arrays using different protocols (e.g., iSCSI to one array, Fibre Channel to another), giving administrators flexibility without enforcing uniformity across all connections.

Why the distractors are wrong:

• A is wrong because iSCSI is not required; FC, FCoE, or NVMe-oF are equally valid - no single protocol is mandated.
• C is wrong because there is no "alternating protocol" requirement for CNA connections; CNAs support multiple protocols simultaneously, not in alternation.
• D is wrong because it directly contradicts the actual rule - hosts are not forced to use one protocol across all connected arrays.

Memory tip: Think "B for Bring-your-own-protocol" - each array connection is independent, so the host brings whatever protocol works best for that array, not a single protocol for all of them.
