Question :-

Scenario: A manufacturing company has deployed Citrix Presentation Server for its ERP application at its manufacturing facilities in Cleveland and Pittsburgh. At each of these two locations, three Citrix Presentation Servers have been deployed because this is where the majority of the users are located. At the Headquarters site, eight Citrix Presentation Servers have been deployed, along with the back-end databases for the ERP application. Users have been complaining that the ERP application response time is intermittently slow throughout the day. Upon reviewing the WAN link statistics, it appears that the WAN links between the headquarters location and each of the manufacturing facilities are only used at a rate of approximately 50% throughout the day. Usage typically jumps to 70-80% during the first business hour based on users accessing work orders and placing supply orders. Based on this information, what should you recommend to this manufacturing company?
Replicated copies of the back-end databases should be placed at the two manufacturing facilities.
A centralized data center geographically equidistant from headquarters, Cleveland and Pittsburgh should be created to house all of the databases and Citrix Presentation Servers.
Additional bandwidth should be leased or Quality of Service should be implemented.
All of the Citrix Presentation Servers should be moved to the headquarters location.
