Topic 1, Main Questions (240 Main Questions) IS management has decided to rewrite a legacy customer relations system using fourth generation languages (4GLs). Which of the following risks is MO... ST often associated with system development using 4GLs? A. Inadequate screen/report design facilities B. Complex programming language subsets C. Lack of portability across operating systems D. Inability to perform data intensive operations Answer: D Explanation: 4GLs are usually not suitable for data intensive operations. Instead, they are used mainly for graphic user interface (GUI) design or as simple query/report generators. Which of the following would be the BEST method for ensuring that critical fields in a master record have been updated properly? A. Field checks B. Control totals C. Reasonableness checks D. A before-and-after maintenance report Answer: D Explanation: A before-and-after maintenance report is the best answer because a visual review would provide the most positive verification that updating was proper. Which of the following is a dynamic analysis tool for the purpose of testing software modules? A. Blackbox test B. Desk checking C. Structured walk-through D. Design and code Answer: A Explanation: A blackbox test is a dynamic analysis tool for testing software modules. During the testing of software modules a blackbox test works first in a cohesive manner as one single unit/entity, consisting of numerous modules and second, with the user data that flows across software modules. In some cases, this even drives the software behavior. Which of the following is MOST likely to result from a business process reengineering (BPR) project? A. An increased number of people using technology B. Significant cost savings, through a reduction in the complexity of information technology C. A weaker organizational structures and less accountability D. Increased information protection (IP) risk will increase Answer: A Explanation: A BPR project more often leads to an increased number of people using technology, and this would be a cause for concern. Incorrect answers: B. As BPR is often technology oriented, and this technology is usually more complex and volatile than in the past, cost savings do not often materialize in this areA. D. There is no reason for IP to conflict with a BPR project, unless the project is not run properly. Which of the following devices extends the network and has the capacity to store frames and act as a storage and forward device? A. Router B. Bridge C. Repeater D. Gateway Answer: B Explanation: A bridge connects two separate networks to form a logical network (e.g., joining an ethernet and token network) and has the storage capacity to store frames and act as a storage and forward device. Bridges operate at the OSI data link layer by examining the media access control header of a data packet. Which of the following is a benefit of using callback devices? A. Provide an audit trail B. Can be used in a switchboard environment C. Permit unlimited user mobility D. Allow call forwarding Answer: A Explanation: A callback feature hooks into the access control software and logs all authorized and unauthorized access attempts, permitting the follow-up and further review of potential breaches. Call forwarding (choice D) is a means of potentially bypassing callback control. By dialing through an authorized phone number from an unauthorized phone number, a perpetrator can gain computer access. This vulnerability can be controlled through callback systems that are available. A call-back system requires that a user with an id and password call a remote server through a dial-up line, then the server disconnects and: A. dials back to the user machine based on the user id and password using a telephone number from its database. B. dials back to the user machine based on the user id and password using a telephone number provided by the user during this connection. C. waits for a redial back from the user machine for reconfirmation and then verifies the user id and password using its database. D. waits for a redial back from the user machine for reconfirmation and then verifies the user id and password using the sender's database. Answer: A Explanation [Show More]
