Congratulations. You have just been hired by AMPR Marketing and Public Relations as their new networking technologist. Your first order of business will be to evaluate the current status of AMPR's networks. AMPR has three offices, one in Los Angeles, which is the corporate headquarters, one in New York, and another in Chicago. You are aware that there are plans to open two additional offices in Miami and Nashville. You have asked Jessica, the Los Angeles office LAN administrator, for help in your analysis. However, Jessica has told you that she is very busy and not able to provide you with much support. She also indicates that there is little written documentation as to how the various offices are set up. Following is her brief description of the Los Angeles office. Later you will visit the New York and Chicago offices to determine how they are configured. For now, Jessica tells you they have a similar, though smaller, set-up: New York has 18 hosts and Chicago has 14 hosts. The corporate office in Los Angeles is the oldest. It has 24 hosts. After three months of offices integration, the president Mcclain called you for a meeting with offices managers to listen to their network problems and complains they had received from some potential clients. Some of these problems are service unavailability for few seconds, some images and videos arrive corrupted, picture freezing, voice overlapping and so on. After this meeting, Mcclain requested you to review the Service Level Agreements (SLAs) with ISPs to overcome these problems. Beside, Mcclain requested you to put restriction on download some unnecessary and unrelated to the company function (as example you tubes) by some employees to avoid any momentary traffic peak over capacity. You met with Jessica to assess the technical way she normally uses to check the availability and latency for any host or router in the network. You learned from her that she still use Ping software built within the operating system. As the network expanded after integration, manually pinging a wide range of hosts and routers could take a prohibitive amount of time
