What are two network requirements for an operational Hitachi Device Manager installation? (Choose two.)

Question

Options

• Aa TCP/IP network for connection between the management server and the management clients
• Ba TCP/IP network for connection of the management server to the storage systems
• Ca Fiber Channel connection between the management server and the storage systems
• Da public subnet for connection between the management server and the management clients

• A
  95% (41)
• C
  2% (1)
• D
  2% (1)

Explanation

Hitachi Device Manager requires TCP/IP connectivity in two directions: from management clients (like browsers or admin consoles) to the management server (A), and from the management server to the storage systems it manages (B) - both are essential for the software to function end-to-end.

C is wrong because Device Manager communicates with storage systems over TCP/IP (typically via storage management interfaces), not a direct Fibre Channel connection - FC is a storage data protocol, not a management protocol in this context. D is wrong because a public subnet is not required; the connection between management server and clients works on any TCP/IP network, including private subnets, which is actually more common and secure in enterprise environments.

Memory tip: Think of the two TCP/IP links as a chain - Client → (TCP/IP) → Management Server → (TCP/IP) → Storage. Both links must exist, and "TCP/IP" is the key phrase; anything mentioning FC or demanding a public network is a distractor.
