The hospital building has 8 floors, with floors 1-3 containing medical and administrative offices and floors 4-8 containing patient rooms. Current network has 8 segments (1 per floor, consisting of Ethernet hubs and switches) that connect to a single router that also connects to the Internet. Floor one contains application and database servers with medical and patient records. There is a plan to increase the number of servers and upgrade them to faster hardware, with high availability being a requirement. The user currently complains of slow access to servers.

The administration wants to install a secure wireless network on floors 4-8, so doctors and nurses could have mobile access to all patient records, x-rays, etc. wherever they are on patient floors. The number of wired devices on all floors is also expected to increase.

Prepare a logical diagram of the current network.

What would you recommend to improve the switching speed between floors and ensure future scalability?

What would you recommend to ensure high availability of the application servers?

What solution would you recommend for WLAN access?

Draw a logical diagram of the proposed network.
