Which two of the following options should you configure? (Choose two).

A.
You should select the option for a Dynamic MAC Address.

B.
You should select the option for a Static MAC Address.

C.
You should tick the Enable Spoofing of MAC Addresses checkbox.

D.
You should clear the Enable Spoofing of MAC Addresses checkbox.

Explanation:
Answers C, B
In order for NLB service to function properly, it will assign all clustered NIC the same MAC address. It cannot do
this if spoofing is disabled, so answer C is valid. Additionally, we want to make sure that once the MAC
addresses are set by NLB, they don’t change, this means answer B is valid.

(Since VMM is an abstraction to hyperv, we can assume hyperV NLB requirements are the same as VMM NLB
requirements.)
