1. The MOST likely explanation for the use of applets in an Internet application is that:
A) it is sent over the network from the server.
B) the server does not run the program and the output is not sent over the network.
C) they improve the performance of the web server and network.
D) it is a JAVA program downloaded through the web browser and executed by the web server of the client machine.
2. Which of the following systems or tools can recognize that a credit card transaction is more likely to have resulted from a stolen credit card than from the holder of the credit card?
A) Intrusion detection systems
B) Data mining techniques
C) Firewalls
D) Packet filtering routers
3. Functionality is a characteristic associated with evaluating the quality of software products throughout their life cycle, and is BEST described as the set of attributes that bear on the:
A) existence of a set of functions and their specified properties.
B) ability of the software to be transferred from one environment to another.
C) capability of software to maintain its level of performance under stated conditions.
D) relationship between the performance of the software and the amount of resources used.
4. During the development of an application, the quality assurance testing and user acceptance testing were combined. The MAJOR concern for an IS auditor reviewing the project is that there will be:
A) increased maintenance.
B) improper documentation of testing.
C) inadequate functional testing.
D) delays in problem resolution.
5. The GREATEST advantage of rapid application development (RAD) over the traditional system development life cycle (SDLC) is that it:
A) facilitates user involvement.
B) allows early testing of technical features.
C) facilitates conversion to the new system.
D) shortens the development time frame.
A) it is sent over the network from the server.
B) the server does not run the program and the output is not sent over the network.
C) they improve the performance of the web server and network.
D) it is a JAVA program downloaded through the web browser and executed by the web server of the client machine.

1. Right Answer: C
Explanation: An applet is a JAVA program that is sent over the network from the web server, through a web browser and to the client machine; the code is then run on the machine. Since the server does not run the program and the output is not sent over the network, the performance on the web server and network-over which the server and client are connected-drastically improves through the use of applets. Performance improvement is more important than the reasons offered in choicesA and B. Since JAVA virtual machine (JVM) is embedded in most web browsers, the applet download through the web browser runs on the client machine from the web browser, not from the web server, making choice D incorrect.
2. Right Answer: B
Explanation: Data mining is a technique used to detect trends or patterns of transactions or data. If the historical pattern of charges against a credit card account is changed, then it is a flag that the transaction may have resulted from a fraudulent use of the card.
3. Right Answer: A
Explanation: Functionality is the set of attributes that bears on the existence of a set of functions and their specified properties. The functions are those that satisfy stated or implied needs. Choice B refers to portability; choice C refers to reliability and choice D refers to efficiency.
4. Right Answer: C
Explanation: The major risk of combining quality assurance testing and user acceptance testing is that functional testing may be inadequate. Choices A, B and D are not as important.
5. Right Answer: D
Explanation: The greatest advantage of RAD is the shorter time frame for the development of a system. Choices A and B are true, but they are also true for the traditional systems development life cycle. Choice C is not necessarily always true.
