CHAPTER 16
Comprehensive Scenarios
The case studies and questions in this chapter draw on your knowledge of CCDA exam
topics. Use these exercises to help master the topics as well as to identify areas you still
need to review for the exam.
Understand that each scenario presented encompasses several exam topics. Each scenario,
however, does not necessarily encompass all the topics. Therefore, work through all the
scenarios in this chapter to cover all the topics. Your CCDA exam will probably contain
questions that require you to analyze a scenario. This chapter contains four case studies
that are similar in style to the ones you might encounter on the CCDA exam. Read
through each case study and answer the corresponding questions. You will find the an-
swers to the case study questions at the end of each scenario. Sometimes more than one
solution can satisfy the customer's requirements. In these cases, the answers presented
represent recommended solutions developed using good design practices. An explanation
accompanies the answer where necessary.
Mr. Robertson, the IT director at Pearland Hospital, is responsible for managing the net-
work. Mr. Robertson has requested your help in proposing a network solution that will
meet the hospital's requirements. The hospital is growing, and the management has re-
leased funds for network improvements.
The medical staff would like to be able to access medical systems using laptops from any
of the patient rooms. Doctors and nurses should be able to access patient medical records,
x-rays, prescriptions, and recent patient information. Mr. Robertson purchased new servers
and placed them in the data center. The wireless LAN (WLAN) has approximately 30 lap-
tops, and about 15 more are due in six months. The servers must have high availability.
Patient rooms are on floors 6 through 10 of the hospital building. Doctors should be able
to roam and access the network from any of the floors. A wireless radio-frequency (RF)
survey report mentions that a single access point located in each communication closet
can reach all the rooms on each floor. The current network has ten segments that reach a
single router that also serves the WAN. Only a single link is used from the floors to the
core router. The router is running Open Shortest Path First (OSPF) Protocol, and they
want to move to a routing protocol that is easier to manage. The back-end new servers are
located in the same segment as those used on floor 1. Mr. Robertson mentions that users
addresses (see Table 16-1).
