HOTSPOT
Your network contains three application servers that run Windows Server 2012 R2. The application
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.
You need to configure a port rule for Appl.
Which port rule should you use?
To answer, select the appropriate rule in the answer area.
Answer: 
Explanation:
* 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.
this should be the bottom left one.
We connect using TCP not UDP => So Protocol needs to be TCP only
connections must be distributed evenly between hosts => So we need to choose multiple host and not Single Host
App1 does not use session state information => So Affinity must be none

David is a fruitcake. there are other variations of this question and he has obviously not read this and just pasted the same answer. it clearly says app1 requires stateful info captuyre

Answer is correct. App1 does use session state info so affinity must be single. @david, you may be answering to a different question.

David is confusing with this question:

SSL is statefull. You setup for multiple hosts so any of the servers can answer the initial request. You setup affinity for Single so the session stays with the same server upon reconnect.
Given answer is correct.

I concur with top-right option; Multiple hosts with Affinity=Single

I believe top right (given Answer) is right
Normally web applications are used by multiple users and there is a need to maintain the state of a user’s session within the web application. Each visitor connected to the web application will have their own session and a session encompasses all the requests from a single visitor within a specified period of time.
Sessions help to maintain user related variables and by maintaining the state of sessions, the application can ensure the user can complete a set of actions, like online shopping using a shopping cart application. Client affinity can be configured in Network Load Balancing (NLB) which helps in maintaining application sessions. Client affinity uses a combination of the source IP address and source and destination ports to direct multiple requests from a single client to the same server. Three types of affinity settings can be configured in Network Load Balancing (NLB).
• None: Multiple requests from the same client are not redirected to the same server by Network Load Balancing (NLB)
• Single: Multiple requests from the same client IP address should be redirected to the same server by Network Load Balancing (NLB)
• Class C: Multiple requests from the same Class C address range are redirected to the same server by Network Load Balancing (NLB). Class C affinity is useful for clients that use multiple proxy servers to access the cluster.
The three filtering modes available are
• Disabled: No filtering.
• Single Host: Direct traffic to a single host.
• Multiple Hosts: Distribute traffic between the Network Load Balancing (NLB) cluster servers.
