You need to improve the response time of the application

You are the network administrator for your company. All servers run Windows Server 2003. The network contains two Web servers named Server1 and Server2 and three application servers named Server3, Server4, and Server5. All five servers have similar hardware. The servers are configured as Network Load Balancing clusters, as shown in the exhibit.

A Web services application hosted on Server1 and Server2 communicates to application components hosted on Server3, Server4, and Server5 by using the IP address 10.1.20.11. The application is designed to be stateless. The Network Load Balancing settings for each server are listed in the following table.

Host Filtering mode Host priority Affinity Load Server1 Multiple Single Equal Server2 Multiple Single Equal Server3 Multiple Single Equal

You need to improve the response time of the application.

What should you do?

Exhibit:

A.
Modify the Network Load Balancing host priorities for Server4 and Server5 to be 1.

B.
Modify the Web services application to access the components on the application servers by using the IP address 10.1.10.11.

C.
Modify the Network Load Balancing affinity setting for Server1 and Server2 to be None.

D.
Modify the Network Load Balancing affinity setting for Server3, Server4, and Server5 to be None.

E.
Modify the Network Load Balancing host priority for Server2 to be 1.

Explanation:
In simple terms, affinity is the attraction one item feels for another item. Selecting None specifies that NLB doesn’t need to direct multiple requests from the same client to the same NLB host, thereby splitting the load and improving response times and reliability.
