1. You have been hired by a small company that has set up a VPN. The VPN is used by two business partners with which the company needs to communicate on a regular basis. You set up a simple mesh configuration, going from office to office to do the initial confis tion, which includes SA table listings for all devices in the VPN. The VPN operates smo Prepar until your company purchases another business that has branch offices located overseas. You are given the assignment of expanding the VPN to include the new employees. You are told that all internal LANs should be able to communicate with one another and are told in confidence that more acquisitions may be in store. You are happy about the prospect of traveling overseas to extend the VPN, but the prospect of updating four or more VPN devices around the world on a regular basis seems impractical. What should you do to help the VPN grow? 2. Your company (the same one from the previous exercise) does indeed follow through with the purchase of a distribution center located in another state. You are told, however, that only the central office and one branch office will need to communicate with the distribution center, to send delivery instructions and maintain shipping records. You are told that speed is of the essence in getting updated records, particularly at budget time each spring. What is the best way to expand this VPN? 3. Once the expanded VPN mentioned in the previous exercise is up and running, you notice significant slowdowns in communications, particularly with one Asian branch office. What are your options for speeding up communications with this single office? Give two alternatives. 4. Your VPN uses transport mode to send traffic to other VPN participants. The network administrator of one of the LANs in the VPN e-mails you an alert stating that his network has been infected with the W32.Storm virus. Because all communications between your LAN and the other LAN go through a VPN, you feel reasonably confident that you won't be infected. Nevertheless, the next day a computer on your machine reports that its antivirus software has isolated the same virus. How could this have happened, and what steps can you take to reduce the chances of it happening again
