CCNA Exercise - Building a Network for a Company with Six Sites

[deanwebb]

The below situation is for those looking for a way to study/prep for a CCNA exam. Feel free to start another thread in this part of the forum to discuss your answers, but this thread will be locked so that people can approach this exercise "fresh". Enjoy!



A company has a networking problem. It has one main site with 1000 employees and five regional sites, each with 200 employees. Each employee has a desktop PC, a VoIP phone, and a wireless tablet, 6000 endpoint devices, total. All devices are connected via hubs and are on the 10.0.0.0 network with a 255.0.0.0 subnet mask. Network activity is overwhelmed by broadcast storms.

You have been hired to fix this problem. The company has purchased 12 routers - 2 for each location. Why would the company want 2 routers per location?

The company has also purchased sufficient layer 3 capable switches for each location. Why would the company desire layer 3 capable switches?

Assign IP ranges to each site, using ranges in the 10.0.0.0 range. Include ranges for the point-to-point connections from the main site to each regional site.
Will you have separate ranges for data, voice, and wireless networks? Why or why not?
If you wanted to have each site linked to each other site in a full mesh, what method would be preferable to defining 15 static routes between each site?
