Which service or Application should you configure?

HOTSPOT
A company runs a third-party DHCP Application on a windows Server 2008 R2 server. The Application
runs as a service that launches a background process upon startup. The company plans to migrate
the DHCP Application to a Windows Server 2008 R2 failover cluster. You need to provide high
availability for the DHCP Application. Which service or Application should you configure?
To answer, select the appropriate service or Application in the answer area.

Explanation:

Windows Server 2008 (and R2) Failover Clustering supports virtually every workload which comes
with Windows Server, however there are many custom and 3rd party applications which take
advantage of our infrastructure to provide high-availability. Additionally there are some applications
which were not originally designed to run in a failover cluster. These can be created, managed by

and integrated with Failover Clustering using a generic container, with applications using the Generic
Application resource type.
We use the Generic Application resource type to enable such applications to run in a highly-available
environment which can benefit from clustering features (i.e. high availability, failover, etc.).
When a generic application resource is online, it means that the application is running. When a
generic application is offline, it means that the application is not running.

A cluster-unaware application is distinguished by the following features.
The application does not use the Failover Cluster API. Therefore, it cannot discover information
about the cluster environment, interact with cluster objects, detect that it is running in a cluster, or
change its behavior between clustered and non-clustered systems.
If the application is managed as a cluster resource, it is managed as a Generic Application resource
type or Generic Service resource type. These resource types provide very basic routines for failure
detection and application shutdown. Therefore, a cluster-unaware application might not be able to
perform the initialization and cleanup tasks needed for it to be consistently available in the cluster.
Most older applications are cluster-unaware. However, a cluster-unaware application can be made
clusteraware by creating resource types to manage the application. A custom resource type provides
the initialization, cleanup, and management routines specific to the needs of the application.
There is nothing inherently wrong with cluster-unaware applications. As long as they are functioning
and highly available to cluster resources when managed as Generic Applications or Generic Services,
there is no need to make them cluster-aware. However, if an application does not start, stop, or
failover consistently when managed by the generic types, it should be made cluster-aware.
