Robert is designing a new Active Directory Domain Services infrastructure for a company called Litware, Inc., which has its headquarters in New York and two additional offices in London and Tokyo. The London office consists only of sales and marketing staff, it does not have its own IT department. The Tokyo office is larger, with representatives from all the company departments, including a full IT staff. The Tokyo office is connected to the headquarters using a 256-Kbps demand-dial link, and the London office has a 128-Mbps connection. The company has registered the litware.com domain name, and Robert has created a subdomain called inside.litware.com for use by Active Directory. Based on this information, design an Active Directory infrastructure for Litware, Inc. that is as economical as possible, specifying how many domains to create, what to name them, how many domain controllers to install, and where to install them. Note: you don't need to implement it, just present your design.
