You have an application named App1. App1 is distributed to multiple Hyper-V virtual machines in
a multitenant environment. You need to ensure that the traffic is distributed evenly among the virtual
machines that host App1. What should you include in the environment?
A.
Network Controller and Windows Server Network Load Balancing (NLB) nodes
B.
Network Controller and Windows Server Software Load Balancing (SLB) nodes
C.
an RAS Gateway and Windows Server Network Load Balancing (NLB) nodes
D.
an RAS Gateway and Windows Server Software Load Balancing (SLB) nodes
I believe the answer is B. I wish I could find definitive proof of this but do a Google search on Network Controller SLB Policies and you’ll find a number of results that indicate just how central the Network Controller is to the entire SLB architecture. It even controllers the RAS Gateway in SLB. Below is a quote that gives some suggestion that it would be what manages the distribution of traffic. The answer could still be something else but I’d go with B.
“This Network Controller feature allows you to enable multiple servers to host the same workload, providing high availability and scalability.”

This article goes into further detail of how load balancing works in SLB and the Network Controller’s role. RAS Gateway doesn’t even factor into it

SLB provides a multitenant unified edge by seamlessly integrating with Microsoft appliances such as the RAS Multitenant Gateway, Datacenter Firewall, and Route Reflector.
Answer: D
In Windows Server 2016, RAS Gateway routes network traffic between the physical network and VM network resources, regardless of where the resources are located. You can use RAS Gateway to route network traffic between physical and virtual networks at the same physical location or at many different physical locations.
Whereas, Network Controller is more concerned with *management* of the network infrastructure by communicating with network devices, services, and components by using the Southbound API, thus, allowing it to discover network devices, detect service configurations, and gather all of the information you need about the network. In addition, the Southbound API gives Network Controller a pathway to send information to the network infrastructure, such as configuration changes that you have made.
So, even though it can manage distribution of traffic, this traffic is network management traffic. Network Controller allows you to configure, monitor, program, and troubleshoot the network infrastructure under its control.
