You work as a Network Administrator at ABC.com. The company network consists of a single Active Directory
Domain Services (AD DS) domain named ABC.com. All servers on the network run Windows Server 2012.
Company developers are developing a custom line-of-business application named CorpApp. The application
will be a secure web based application and will run in Internet Information Services (IIS) 8.0.
You need to configure a server solution to host the CorpApp application. You plan to install two Windows
Server 2012 servers and configure Network Load Balancing between the servers. You install the two servers
and install the Network Load Balancing (NLB) feature. You learn that the CorpApp application will save user
state information locally on the NLB cluster node.
How can you configure the NLB cluster to ensure that user session state is maintained?
A.
By configuring the client affinity to Single.
B.
By configuring the preferred owner setting.
C.
By configuring the client affinity to None.
D.
By configuring the client affinity to Class C.
E.
By configuring the possible owner setting.
Correct.
Single Affinity
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. 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. Additionally, these clients cannot use Class C affinity because intranet clients typically have IP addresses within a narrow range. It is likely that this range is so narrow that all clients on an intranet have the same Class C address, which means that one member might process all of the requests while other members remain idle.
