1. AAA Video operates a chain of 50 video rental stores located in the Northwestern United States. They
currently have a Point-of-Sale (POS) system in which each store posts its daily sales data and inventory
changes to a central database through dial-up communication. There is no interaction between the stores
and the central system during business hours. The central site runs on an Ethernet LAN. The only
always-on WAN link is an Internet connection using wireless broadband to a local ISP. AAA wants to
enhance their service offering by creating a new E-Commerce web site where customers can browse and
search a catalog of video titles and select the ones they want for rental. The system will instantly
communicate the order to the nearest store where employees pull the order and hold it until the customer
picks it up. The service must operate on a 24x7 basis. AAA sees this new business strategy as a means
to increase revenue and expand the business nationally. They see an opportunity to expand the web site
in the future to video, DVD and music sales on a worldwide level. The company wants all stores to be
connected to the central site through WAN links. The company is upgrading the central inventory
database so that sales and rentals can be posted immediately in real-time. An Internet-based email and
instant-messaging system will be set up for all headquarters employees and store managers to use. AAA
believes that networking the stores will improve order fulfillment processes which will improve customer
satisfaction and thus, boost revenue. It will also help communication with store employees. AAA wants to
upgrade the local LAN to a Gigabit and Fast Ethernet system to facilitate the demands of the new and
upgraded systems. They have budgeted $500,000 for the networking equipment and another
$10,000/month for the WAN charges including a faster Internet connection. They believe that 256Kbps
speeds will be adequate to the stores. Since they have no staff capable of managing the new network,
they will hire two engineers that already have the training and experience. The project must be complete
in 6 months when the new inventory system goes online. The IT manager has concerns about the security
of the servers and workstations on the network when all stores become connected. He doesn't want any
Internet access to or from the stores. He is depending on you to recommend an effective yet affordable
solution that will protect his system from intruders.Which two are business constraints imposed by the
AAA Video Company on this new network design project? (Choose two.)
A. the $10,000/month WAN budget
B. the installation of WAN links to all stores
C. the lack of any existing IT staff
D. video sales through the global Internet
