Windows Server 2016. All of the offices are connected by high speed, low latency WAN links.

I have found true answer from microsoft book:
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
So, correct answer is E

Looks like Data Centre Bridging, when you select the feature it has IEEE in the description.
