What should you configure?

Information and details provided in a question App1y only to that question.
Your network contains an Active Directory domain named contoso.com. The domain contains two member
servers named Server1 and Server2. All servers run Windows Server 2012 R2. Server1 and Server2 have the
Network Load Balancing (NLB) feature installed. The servers are configured as nodes in an NLB cluster named
Cluster1.
Cluster1 hosts a secure web Application named WebApp1. WebApp1 saves user state information locally on
each node.
You need to ensure that when users connect to WebApp1, their session state is maintained.

Explanation:
Client Affinity
NLB offers three types of client affinity to minimize response time to clients and provide generic support for
preserving session state. Each affinity specifies a different method for distributing client requests.
Affinity Single: Single
Multiple requests from the same client must access the same member; useful for clusters within an intranet.
This affinity provides the best support for clients that use sessions on an intranet. These clients cannot use No
affinity because their sessions could be disrupted.
Incorrect:
Not A. Affinity none: Multiple requests from the same client can access any member; useful for clusters that do
not store session state information on individual members.
