Which of the following is NOT an attribute required when creating a LUN?

• A. The path to the LUN.
• B. The size of the LUN.
• C. The version of Data ONTAP.
• D. The host operating system of the system attached to the LUN.

Answer: (C)

When you create a LUN, you need to define where it lives in the storage namespace (the LUN’s path) and how much space it reserves (its size). These two pieces are the fundamental attributes that determine the LUN’s identity and capacity.

The version of Data ONTAP is a system-wide property that applies to the entire 7-Mode system, not to an individual LUN. It isn’t something you specify for each LUN during creation, so it isn’t a required LUN attribute. Similarly, the host operating system that will access the LUN isn’t an intrinsic LUN attribute you set at creation time, though you might consider host-specific considerations later (for access methods or alignment) once the LUN is presented.

So, the attribute not required when creating a LUN is the Data ONTAP version.
