What technology in Windows Server 2016 allows several network interfaces to work together in a coordinated effort to provide load balancing and fault tolerance?

The answer is NIC Teaminng

Explanation:

NIC teaming is one of those very few technologies in Windows server 2016 that is used to optimize network performance. It can be applied on both physical servers and virtual ones. Once NIC Teaming is correctly configured and implemented, we will get the most out of the interfaces that are connected directly to our servers. Say we have several interfaces connected to the server at the same time; we can have a network team configure two or three of these interfaces to work together in a coordinated fashion. As a result, this will provide increased bandwidth and fault tolerance. To get the best results, a network team is required to configure not one but a few NICs in the team. Once we create a team from two interfaces in Windows server, it is going to make it look like one NIC and is going to give us some load balancing and redundancies in case one interface goes down and the other one is still running.
