Scenario
Please read this scenario prior to answering the question
The ArchiSurance enterprise document management infrastructure provides critical support for
myriad types of documents and document-based transactions, many of which are executed in high
volume each day. At the core of the infrastructure is the document management systems software,
which has three major modules: a document engine that stores, retrieves and performs a variety of
operations on documents, a workflow engine that hosts document management applications, and
an application engine, which hosts the most sophisticated applications. The application engine
invokes the document and workflow engines as necessary when hosting application components
that require their services.
The claim management application component is critical to ArchiSurance business operations. It is
hosted by the application engine, and launches whenever an individual files a new claim. The
claim management component requires different documents to demonstrate proof of loss
depending on the type of claim filed, the type of insurance that is in force, and various other
circumstances. When the correct documents are filed and verified by an intake operator, proof of
loss is complete, and the claim management component assigns the claim to a claim analyst by
reading and updating analyst status data and applying business rules stored as data.
Due to its business-critical nature, the document management solution is hosted redundantly at
two geographically separate data center sites known as Site A and Site B. Both sites provide
identical infrastructure. Each site contains a highly available data center network (DCN) that is
connected to the highly available ArchiSurance wide area network (WAN). Each claim
management server is connected to its site DCN, and each DCN is a converged network that
connects both servers and storage arrays, including a physical storage array dedicated to the
claim management application. Each site contains four high-powered separate physical
serversrules stored as data.

dedicated to the claim management application. At any one time, one server is on standby while
the other three servers are, respectively, hosting the document, workflow and application engines.
Each active server provides a monitoring service that is In constant two-way communication with

the monitoring service on the standby server. If a server fails, the surviving monitoring services
perform a failover sequence to assume failed server’s workload if it was active. The surviving
monitoring services also alert the operations team on duty.
Refer to the Scenario
A new IT manager has asked you to model the infrastructure hardware and networks that supports
document management, including the data center sites, servers, storage, and networks as well as
the services necessary for automated failover within a server cluster. Since the two data centers
provide identical document management infrastructure, for Site B it is only necessary to show the
associated networking.
