An administrator would like to connect a server to a SAN. Which of the following processes would BEST allow for availability and access control?

Question

Options

• AInstall a dual port HBA on the SAN, create a LUN on the server, and enable deduplication and data
• BInstall a multipath LUN on the server with deduplication, and enable LUN masking on the SAN.
• CInstall 2 LUNs on the server, cluster HBAs on the SAN, and enable multipath and data deduplication.
• DInstall a dual port HBA in the server; create a LUN on the SAN, and enable LUN masking and multipath.

• A
  4% (1)
• B
  11% (3)
• C

• D

Explanation

The optimal SAN connectivity solution for availability and access control combines: (1) A dual-port Host Bus Adapter (HBA) in the server - provides two independent physical paths to the SAN fabric, eliminating single points of failure; (2) A LUN created on the SAN - Logical Unit Numbers are the access units on a SAN, and they should be provisioned on the SAN, not on the server; (3) LUN masking - a SAN-side access control mechanism that restricts which hosts (by HBA WWN) can see and access specific LUNs, directly addressing access control; (4) Multipath I/O (MPIO) - software that manages multiple physical paths to the SAN for both redundancy and load balancing, enhancing availability. Options A, B, and C either misplace LUN creation on the server, cluster HBAs incorrectly, or miss the correct combination of these components.
