Case Study: ACMC Hospital Modularity
This case study is a continuation of the ACMC Hospital case study introduced in Chapter 2.
In this case study, you apply the Cisco Enterprise Architecture to the ACMC Hospital network requirements and develop a high-level view of the planned network hierarchy. Complete the following steps:
- Step 1 Consider each of the functional areas of the Cisco Enterprise Architecture:
- Enterprise Campus: Including the Campus Infrastructure module (composed of the Campus Core layer, the Building Distribution layer, and the Building Access layer) and the Server farm module
- Enterprise Edge: Including the E-commerce module, the Internet Connectivity module, the WAN and MAN and Site-to-Site VPN module, and the Remote Access and VPN module
- Enterprise Branch
- Enterprise Data Center
- Enterprise Teleworker
Mark up the existing network diagram, provided in Figure 3-37, indicating where each of the modules would be at a high level.

- Step 2 List some key considerations or functions for each of the modules in the Cisco Enterprise Architecture. Indicate whether each module is used in the ACMC Hospital network.
- Step 3 Since the time initial discussions with ACMC occurred, the following additional requirements have surfaced:
- The staff needs Internet access for purchasing supplies and reviewing research documents and new medical products.
- There has been some discussion about allowing employees to telecommute.
- ACMC has a web server for a patient communications and community relations service called "Text a Nurse." This for-fee service allows a patient to send a text message to the hospital, requesting medical advice.
How does this new information change the design? Incorporate the changes into your high-level design, and update the list of modules and considerations.
- Step 4 Which of the following infrastructure or network services are immediately applicable to your design?
- Security services
- Voice services
- Wireless
- Network management
- High availability
- QoS
- Multicast
Are there specific locations or modules where some of these services are particularly relevant?
- Step 5 Indicate where redundancy should be supported in the design.
