Your network contains two Web servers named Server1 and Server2. Both servers run Windows
Server 2012 R2.
Server1 and Seiver2 are nodes in a Network Load Balancing (NLB) cluster. The NIB cluster contains an
application named App1 that is accessed by using the URL http://app1.contoso.com.
You plan to perform maintenance on Server1.
You need to ensure that all new connections to App1 are directed to Server2. The solution must not
disconnect the existing connections to Server1.
What should you run?
A.
The Stop-NlbCluster cmdlet
B.
The nlb.exe stop command
C.
The Suspend-NlbCluster cmdlet
D.
The nlb.exe suspend command
Explanation:
The Stop-NlbClusterNode cmdlet stops a node in an NLB cluster. When you use the stop the nodes in
the cluster, client connections that are already in progress are interrupted. To avoid interrupting
active connections, consider using the -drain parameter, which allows the node to continue servicing
active connections but disables all new traffic to that node.
First one should be Stop-NLBClusterNode.
I guess it is a typo that Node is missing….
I agree with you David. the cmdlet should be Stop-NLBClusterNode
Why would the answer not be suspend C.
because stopping would stop the connections?
Suspending seems to have a more dramatic effect on the host being suspended, look here:
https://technet.microsoft.com/en-us/library/cc771220(v=ws.11).aspx
“Suspending NLB differs from stopping the handling of NLB cluster traffic in that suspending NLB stops NLB on the host and suspends ALL NLB CLUSTER-CONTROL COMMANDS ON THE HOST (except for the resume and query commands). Stopping the handling of NLB cluster traffic stops NLB on the host, but it does not affect the other NLB cluster-control commands”
I am still not exactly sure what all that means.. both SUSPEND and STOP seems to be appropriate for maintenance.. ohh well.. thanks Microsoft.

yes Mnoble says it best
