Question 1

The process of coordinating a program as it changes through construction (like keeping files and programs in different places)is called:
A)Change control
B)Separation of duties
C)Judicial control
D)Scope creep
E)None of these

Accepted Answer

Change control is the process of managing changes to a project, program or system. It involves keeping track of changes to files, programs, and other components of the system, as well as coordinating those changes to ensure that they are implemented correctly and do not disrupt the overall functioning of the system. Separation of duties is a concept related to organizational management, while judicial control refers to the legal system. Scope creep refers to the tendency of a project to expand beyond its original parameters, which is related to but not the same as change control. Therefore, the best answer is A) Change control.

Question 2

Which is generally the best understood component of the SDLC and may offer the fewest problems?
A)Developing the database design
B)Developing the system's software
C)Writing onscreen documentation
D)Changing the data into third normal form
E)Doing interviews

Accepted Answer

B

Question 3

The authors suggest that:
A)"All testing must include live production data"
B)"All testing must include both alphabetic and numeric data"
C)"It is impossible to test every possible combination of input and situation"
D)"Testing rarely pays for itself"
E)"Testing should only be used for complex programs and situations"

Accepted Answer

The authors suggest that it is impossible to test every possible combination of input and situation. This implies that testing needs to focus on the most important and likely scenarios, rather than trying to cover all possibilities. The other options are not supported by the text.

Question 4

A program is not considered finished until:
A)It has been used successfully for six months
B)The cost of developing the program 'breaks-even' with the benefits of the program
C)The ROI is positive
D)It has passed its testing
E)It 'dies' and is replaced by a newer version

Accepted Answer

A program is not considered finished until it has passed its testing and all identified issues have been resolved. While successful use over a period of time, breaking-even on costs, positive ROI, and newer versions are all important considerations, they do not necessarily determine a program's completeness.

Question 5

The term 'bug' in software came from:
A)An English translation of the word for defect in German
B)The story of a moth getting caught inside an early computer
C)The acronym BUG - for binary unknown glitch
D)No one knows the reason
E)None of these

Accepted Answer

The term 'bug' in software came from the story of a moth getting caught inside an early computer. In 1947, a computer operator found a moth stuck between the contacts of a relay inside Harvard University's Mark II Computer, and they labeled it as the "first actual case of bug" in a log book. The term 'bug' was later used to refer to any defect or issue in software.

Question 6

Test plans:
A)Are generally developed by the programmers informally
B)Generally only cover main processing and not the various sub-processes
C)Often have 20 to 30 pages
D)Can be massive with over 200 pages of very explicit plans and directions
E)Can generally be written in three pages or less

Accepted Answer

The answer of Test plans:
A)Are generally developed by the programmers...

Question 7

Which of the following is NOT a general test stage?
A)Unit tests
B)Module tests
C)Integration tests
D)System tests
E)Acceptance tests

Accepted Answer

Module tests are not a general test stage. The common general test stages in software testing are unit tests, integration tests, system tests, and acceptance tests. Module testing refers to testing the individual units or components of code within a larger system, and is typically considered a type of unit testing.

Question 8

A major credit card company has an hour of system downtime on the Friday after Thanksgiving (generally one of the biggest shopping days of the year).Which might be a good estimate of the amount of income lost from this outage?
A)Under $50,000
B)From $50,000 to $99,999
C)From $100,000 to $249,999
D)From $250,000 to $500,000
E)Over $500,000

Accepted Answer

The Friday after Thanksgiving is one of the busiest shopping days of the year, and a major credit card company is likely processing a significant amount of transactions during that time. With an hour of downtime, it is reasonable to expect that a large number of transactions could be lost or delayed, resulting in potentially significant lost revenue. Therefore, it is safe to assume that the amount of income lost from this outage would be over $500,000.

Question 9

During the implementation phase of the SDLC:
A)Analysts will write programs
B)Programmers will develop user interfaces
C)Project managers will convert logical ERDs into physical DFDs
D)Champions will do the data management design
E)None of these

Accepted Answer

During the implementation phase of the SDLC, programmers typically write code and develop the system, but the specific tasks mentioned in options A, B, C, and D are not accurately described or assigned to the correct roles.

Question 10

According to the textbook,which of the following is not a cause of project failure?
A)Flaws in analysis
B)Flaws in aesthetics
C)Flaws in user interface design
D)Flaws in database design
E)Flaws in developing correct system specifications

Accepted Answer

The textbook doesn't mention flaws in aesthetics as a cause of project failure. The other options are mentioned as possible causes of project failure.

Question 11

The authors describe "writing programs" as:
A)A fun,creative activity
B)A tedious process
C)A very mathematical and logical process
D)An excellent learning process for end-users
E)Answers B and C

Accepted Answer

The answer of The authors describe "writing programs" as:
A)A fun,creative...

Question 12

If a program module is taking longer to develop than expected,the recommended action is:
A)Put more programmers on the staff
B)Force the developers to work weekends to catch up
C)Move the expected completion date back
D)Incorporate scope creep into the requirements
E)Change the development environment into an object-oriented language

Accepted Answer

Moving the expected completion date back is the best choice because it is important to communicate realistically with stakeholders about the progress of the project. Adding more resources or forcing developers to work longer hours may not be as effective if the issue is related to fundamental challenges with the module. Incorporating scope creep into the requirements or changing the development environment may not directly solve the issue and could cause further delays.

Question 13

Unit tests focus on:
A)All modules (all units)
B)Users and their acceptance of how a specific unit works
C)A program or a program module
D)Interact screen forms
E)How the overall system functions

Accepted Answer

Unit tests focus on testing individual program modules, not the overall system or user acceptance.

Question 14

When testing individual modules,it sometimes happens that some modules are not finished when testing starts,so the programmer usually writes _______ for the unfinished modules to enable the modules around them to be tested.
A)"By-passes"
B)"Temporary Modules"
C)"Placeholder Modules"
D)"Stub Modules"
E)"End Modules"

Accepted Answer

The programmer usually writes "Stub Modules" for the unfinished modules to enable the modules around them to be tested. Stub modules are dummy modules or functions that simulate the behavior of the actual module or function that is not yet finished. They can be designed to return a fixed value or predefined behavior that other modules can interact with, allowing the testing process to continue without waiting for the unfinished modules to be completed.

Question 15

During the implementation phase of the SDLC:
A)System is built
B)System is tested
C)System is documented
D)All of these

Accepted Answer

During the implementation phase of the SDLC, the system is built, tested, and documented. This is the phase where the actual system is developed based on the requirements gathered and designed in the previous phases. The developed system is then tested to ensure that it performs according to the requirements and specifications. Documentation is also created to ensure that the system can be maintained and supported by the organization. Therefore, all of these options are correct.

Question 16

On test plans:
A)Each individual test has a specific objective and describes a set of very specific test cases to examine
B)Each user must contribute to the specific goals of the test plan
C)Each member of the project team,plus all developers (programmers)must identify one specific application that they will test
D)Only the master project manager tests,and only after all coding has been completed in what is called the "Omega" test
E)The use of multiple choice options has been shown to effectively assess to a 99.9% accuracy rate

Accepted Answer

Each individual test should have a specific objective and detailed set of test cases to examine in order to ensure thorough testing of the software.

Question 17

Bridget is managing a systems development project.The programmers have gotten farther and farther behind in the schedule.One thing she should NOT do is:
A)Use a code generator that comes with high-end CASE tools
B)Add more programmers to the development team
C)Keep communication channels open
D)Hold weekly meetings
E)Keep close tabs on the process so it doesn't slip farther

Accepted Answer

Adding more programmers to the team may actually make the project fall further behind schedule due to the time needed for new team members to understand the project, code, and processes. This option is also called Brooks' law, which states that adding more people to a late software project makes the project later. Instead, Bridget should consider other options such as using a code generator or re-evaluating the project timeline and scope.

Question 18

The test objective is taken directly from:
A)The results of the JAD session
B)The program specification
C)The use-cases
D)The project sponsor
E)The questions raised in a focus-group application

Accepted Answer

The test objective is derived from the program specification which details the features and functionalities of the software to be developed. The other options - JAD sessions, use-cases, project sponsor, and focus-group applications - may provide useful information for the software development process but they do not directly determine the test objectives.

Question 19

Generally,most errors (defects)are found in which two testing periods?
A)Unit testing and integration testing
B)Integration testing and system testing
C)System testing and acceptance testing
D)Unit testing and acceptance testing
E)Alpha testing and beta testing

Accepted Answer

The answer of Generally,most errors (defects)are found in which two...

Question 20

The largest single component of any systems development project in terms of both time and cost could be:
A)Conducting JAD sessions
B)Gamma testing
C)Developing the user interface
D)Writing programs
E)Having meetings

Accepted Answer

Writing programs is typically the most time-consuming and expensive aspect of systems development. It involves designing, coding, testing, and debugging the software that will ultimately run the system. While other activities such as conducting JAD sessions and developing the user interface are also important, they typically require less resources and time than writing programs. Gamma testing and having meetings are also important, but they are not the largest single component of a systems development project.
