Your network contains two Web servers named Server1 and Server2. Both servers run Windows
Server 2012 R2.
Server1 and Server2 are nodes in a Network Load Balancing (NLB) cluster.The NLB 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 Set-NlbCluster cmdlet
B.
The nlb.exe suspend command
C.
The nlb.exe stop command
D.
The Suspend-NlbClusterNode cmdlet

Given answer is INCORRECT.
Correct answer: C
The question refers to NLB. You have to use the ‘nlb.exe stop command’ (use drain instead of ‘command’).
Look here:

Agree… this issue has happend in previous questions (with the same text and answers)

Actually (using your link for nlb), it clearly states that nlb.exe stop will stopp everything immediately, you’d need to use nlb.exe drainstop.
So there is no correct answer here.

Furthermore the given link in the explanation refers to Failover Cluster Services, not to NLB!

The Drain coommand can also be used with Suspend-nlbclusternode.

No it can’t. Stop-NlbCluster -drain, not set or suspend. Suspend -drain, not even a parameter.
“Stop-NlbClusterNode -InputObject [-Drain] [-Timeout ] []
”
As for set-
“Detailed Description
The Suspend-NlbClusterNode cmdlet suspends a specific node in an NLB cluster. You might need to suspend a node in a cluster to override any remote control commands that are issued or for maintenance work.”

The answers given here are wrong. You can either use;
nlb.exe drainstop
OR
Stop-NlbClusterNode -drain

nlb drainstop would stop the entire cluster, the parameter that can be passed to nlb is cluster name, not node name.
Stop-NlbClusterNode -drain would do the job.

Agree with Halloween, answers are wrong.

but if all given answers are wrong (which they obviously are!), how is it possible to answer this question in exam correctly??

The answers in exam will be different. this question was copied with wrong answers.
In the exam, one of the answer’s will be ” Stop-nlbclusterNode -Drain ” or “nlb.exe -drainstop ”
either of those are correct.
