Your company has 10 offices. Each office has a local network that contains several Hyper-V hosts that run
Windows Server 2016. All of the offices are connected by high speed, low latency WAN links.
You need to ensure that you can use QoS policies for Live Migration traffic between the offices.
Which component should you install?
A.
the Data Center Bridging feature
B.
the Routing role service
C.
the Network Controller server role
D.
the Multipath I/O feature
E.
the Canary Network Diagnostics feature

Lol wtf. I’m pretty sure that the right answer is “Install DCB feature”

“This configuration emphasizes the use of RDMA. To converge other workloads such as Live Migration, Cluster and Management on the same RDMA NICs, the NICs must also support Data Center Bridging (DCB). To provide high availability to Storage, you can enable Microsoft Multipath I/O (MPIO)”
so MPIO is for SANs and of course no one uses MPIO to provide anything between remote sites.

As the book says..
“Enable and configure network QoS with Data Center Bridging (DCB)
QoS can help manage your network traffic by enabling you to configure rules that can detect congestion or reduced bandwidth, and then to prioritize, or throttle, traffic accordingly. For example, you can use QoS to prioritize voice and video traffic, which is sensitive to latency.
DCB provides bandwidth allocation to specific network traffic and helps to improve Ethernet transport reliability by using flow control based on priority. Because DCB is a hardware-based network traffic management technology, when you use DCB to manage QoS rules to control network traffic, you can:
* Offload bandwidth management to the physical network adapter.
* Enforce QoS on ‘invisible’ protocols, for example, Remote Direct Memory Access (RDMA).”
So I think the correct one is “A. the Data Center Bridging feature”

Correct answer is A Install the DCB feature. MPIO provides redundancy to Storage only.
