Your network contains an Active Directory domain named contoso.com. The domain contains multiple servers that run Windows Server 2012. All of the servers run as virtual machines on Hyper-V hosts.
The network contains a Remote Desktop Services (RDS) infrastructure. The infrastructure contains four servers. The servers are configured as shown in the following table.
You publish a RemoteApp program named App1. App1 is accessed from client computers by using a web browser.
You need to recommend changes to the RDS infrastructure to meet the following requirements:
App1 must be available from a web browser if Server3 fails. The connection requests for App1 must be distributed evenly between Server3 and Server4.
What should you recommend adding to the RDS infrastructure?
A. A replica of Server3 and Server4 on another Hyper-v host
B. A Network Load Balancing (NLB) cluster that contains Server3 and Server4
C. A failover cluster that contains Server3 and Server4
