You need to ensure that the users see all six RemoteApp programs when they connect to an RD Web Access server.
Which two actions should you perform? (Each correct answer present part of the solution. Choose two.)
A. From RemoteApp Manager, configure the RD Gateway SettingsYour network contains two servers named Server1 and Server2 that run Windows Server 2008 R2.
Server1 and Server2 have the Hyper-V server role and the Failover Clustering feature installed.
You deploy a new virtual machine (VM) named VM1 on Server1.
You need to ensure that VM1 is available if one of the Hyper-V servers fails.
What should you do?
A. Install the Network Load Balancing (NLB) feature on VM1.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
