Exam 70-412 topic 1 question 16 discussion

Actual exam question from Microsoft's 70-412

Question #: 16
Topic #: 1

Your network contains an Active Directory domain named contoso.com. The domain contains two member servers named Server1 and Server2. All servers run
Windows Server 2012 R2.
Server1 and Server2 have the Failover Clustering feature installed. The servers are configured as nodes in a failover cluster named Cluster1. Cluster1 contains a cluster disk resource.
A developer creates an application named App1. App1 is NOT a cluster-aware application. App1 runs as a service. App1 stores date on the cluster disk resource.
You need to ensure that App1 runs in Cluster1. The solution must minimize development effort.
Which cmdlet should you run?

A. Add-ClusterGenericServiceRole
B. Add-ClusterGenericApplicationRole
C. Add-ClusterScaleOutFileServerRole
D. Add-ClusterServerRole

Show Suggested Answer

Suggested Answer: B 🗳️
Add-ClusterGenericApplicationRole
Configure high availability for an application that was not originally designed to run in a failover cluster.
If you run an application as a Generic Application, the cluster software will start the application, then periodically query the operating system to see whether the application appears to be running. If so, it is presumed to be online, and will not be restarted or failed over.
EXAMPLE 1.
Command Prompt: C:\PS>
Add-ClusterGenericApplicationRole -CommandLine NewApplication.exe
Name OwnerNode State
---- --------- ----- cluster1GenApp node2 Online

Description -
-----------
This command configures NewApplication.exe as a generic clustered application. A default name will be used for client access and this application requires no storage.
Reference: Add-ClusterGenericApplicationRole

I think it’s A. The questions says “...App1 runs as a service” http://technet.microsoft.com/en-us/library/ee460966.aspx “Configure high availability for a service that was not originally designed to run in a failover cluster.” If you run an application as a Generic Application, the cluster software will start the application, then periodically query the operating system to see whether the application appears to be running. If so, it is presumed to be online, and will not be restarted or failed over

I'm going with the given answer because it is an application, even though it runs as a service. At least until i see a good explanation why not to.

Just another poorly worded question. An application is a service and service is also a process, so the question is here what is the main difference? To make things worse the question mentions application and service.

The answer should be “Add-ClusterGenericServiceRole”. Both Add-ClusterGenericServiceRole and Add-ClusterGenericApplicationRole seem to do exactly the same, with the difference that ClusterGenericApplicationRole checks for services while ClusterGenericApplicationRole checks for processes. If the application runs as a service, then the Failover cluster needs to monitor a service, not a process.
