Which three operations are allowed after enabling security on a Hitachi Unified Storage system Fibre Channel (FC) port? (Choose three.)

Question

Options

• AAdd multiple WWNs to one Host Group.
• BAdd the same WWN to multiple Host Groups on the same FC port.
• CCreate a Host Group with two different host connection modes.
• DAdd a LU to two different Host Groups behind two different ports.
• ECreate Host Groups with different host connection modes on the same FC port.

Explanation

Correct answers: A, D, and E

On a Hitachi Unified Storage system with FC port security enabled, you can add multiple WWNs to a single Host Group (A), add a LU to Host Groups across different ports (D), and create Host Groups with different host connection modes on the same FC port (E) - all of these are standard, valid operations within the Host Group security model.

Option B is incorrect because once security is enabled, a given WWN may only belong to one Host Group per FC port - assigning the same WWN to multiple Host Groups on the same port would create an ambiguous access path and is explicitly prohibited.

Option C is incorrect because a Host Group is assigned exactly one host connection mode (e.g., Windows, HP-UX, Open); you cannot configure two different modes within a single Host Group - that attribute is singular per group.

Memory tip: Think of a Host Group as a "club with one dress code" - a club can have many members (multiple WWNs → A), and a venue (port) can host several clubs with different dress codes (E), but the same guest can't hold memberships in two clubs at the same door (no duplicate WWN per port → rules out B). LUs are like event passes that work at any door (D).
