B.

To use existing supported storage arrays

C.

To use only vSphere Standard Switches

D.

To optimize or reduce licensing costs

E.

To use external storage in addition to local vSphere vSAN for tiering

Question 6

What are two requirements for automatic node discovery? (Choose two.)

Options:

A.
