Which of the following specifies the main reason why you should not use beta drivers in a server environment?

A.
Beta drivers have manufacturing flaws.

B.
Beta drivers have not been extensively tested.

C.
Beta drivers are cheaper than validated drivers.

D.
All of the above.

Explanation:
Because beta drivers have not been extensively tested, you must refrain from installing these drivers in a server environment. You cannot assume that beta drivers are stable enough for the NOS. You should always choose to install the most recent validated driver of the peripheral device.
