1. Right Answer: B
Explanation: A firewall is a set of related programs, located at a network gateway server, that protects the resources of a private network from users of other networks. An enterprise with an intranet that allows its workers access to the wider Internet installs a firewall to prevent outsiders from accessing its own private data resources and for controlling the outside resources to which its own users have access. Basically, a firewall, working closely with a router program, filters all network packets to determine whether or not to forward them toward their destination. A firewall includes or works with a proxy server that makes network requests on behalf of workstation users. A firewall is often installed in a specially designated computer separate from the rest of the network so no incoming request can get directed to private network resources.
2. Right Answer: D
Explanation: A front-end processor is a hardware device that connects all communication lines to a central computer to relieve the central computer.
3. Right Answer: A
Explanation: A GANTT chart is used in project control. It may aid in the identification of needed checkpoints but its primary use is in scheduling. It will not ensure the completion of documentation nor will it provide direction for the post-implementation review.
4. Right Answer: A
Explanation: A gateway performs the job of translating e-mail formats from one network to another so messages can make their way through all the networks.
5. Right Answer: C
Explanation: A global enterprise product reengineering (EPR) software package can be applied to a business to replace, simplify and improve the quality of IS processing.Documentation is intended to help understand how, why and which solutions that have been selected and implemented, and therefore must be specific to the project. Documentation is also intended to support quality assurance and must be comprehensive.
