Rocky Mountain Corporation (RMC) has relocated to a new building that was previously wired and set up for a local area network (LAN).

You have been hired to secure the RMC network and ensure that the company has a properly designed network that allows for future growth (500 users in 12 months) and for the highest levels of security to protect against internal and external attacks. RMC has scheduled a meeting with its key executives and you in order to provide you with any additional information you may need.
