servers have the Network Load Balancing (NLB) feature installed.
You create an NLB cluster that contains the three servers.
You plan to deploy an application named App1 to the nodes in the cluster.App1 uses TCP port 8080
and TCP port 8081.
Clients will connect to App1 by using HTTP and HTTPS. When clients connect to App1 by using
HTTPS, session state information will be retained locally by the cluster node that responds to the
client request.

* Filtering Mode: Multiple hosts
The Multiple hosts parameter specifies that multiple hosts in the cluster will handle network traffic
for the associated port rule. This filtering mode provides scaled performance and fault tolerance by
distributing the network load among multiple hosts. You can specify that the load be equally
distributed among the hosts or that each host will handle a specified load weight.
* Affinity
Select Affinity Single or Network to ensure that all network traffic from a particular client is directed
to the same host.

    I believe the answer is correct. There are three servers in the cluster so filtering mode should be set to multiple host.

    The data being extracted is coming locally, so it seems reasonable to believe a local intranet is in place and it’s an app so the same IP will be used: “In Single affinity, NLB associates clients with particular members by using the client’s IP address. Thus, requests coming from the same client IP address always reach the same member”.
