What should you recommend?

You have a System Center 2012 Virtual Machine Manager (VMM) infrastructure that contains a
visualization host named Server2. Server2 runs Windows Server 2008 R2 Service Pack 1 (SP1).
Server2 has the Hyper-V server role installed. You plan to deploy a service named Service1 to
Server2. Service1 has multiple load- balanced tiers. You need to recommend a technology that must
be implemented on Server2 before you deploy Service1. What should you recommend?

A.
MAC address spoofing

B.
the Network Policy and Access Services (NPAS) server role

C.
TCP Offloading

D.
the Multipath I/O (MPIO) feature

Explanation:
If you want to deploy the service to a Windows Server 2008 R2-based Hyper-V host (with or without
Service Pack 1), you must also enable MAC address spoofing for NLB to work correctly. If you do not,
service deployment will fail. However, you cannot use the Enable spoofing of MAC addresses check
box in the virtual machine template or the associated hardware profile to configure this setting.
Instead, you must use the VMM command shell to configure this setting after you create the
template, or in the hardware profile that you use for the template.
