Correct answer- Bridge About 6 months after the situation described in #5 above the CSO decides that they need to upgrade their equipment and install a device that is application aware meaning that it knows the types of applications the company runs and can better detect and address potentially harmful network traffic reducing the need for a Network Administrator to manually adjust security rules. Correct answer- Next Generation Firewall A medium sized corporation has purchased a competitor, which effectively doubles the size of their business overnight. After performing an analysis of the previous competitor's network, they determine that now that they are a larger company they will upgrade their data center so that they can purchase 10 high powered servers and relocate the 30 different systems used by the two companies onto the 10 servers. They will take each of the 10 servers and allocate resources such a hard drive storage, RAM, and CPUs to 2 or more systems allowing each of the 10 servers to run 2-4 of the systems. There are a couple of advantages to this approach. First, they did not have to purchase 30 servers. Second, they will save on the electric that would have been needed to operate 30 servers. Finally, they can adjust the amount of RAM, CPU speed, or storage to the various systems depending on the number of users logged in.
