Question 1

Which statement is true of Critical Path Method (CPM)?

Accepted Answer

The Critical Path Method (CPM) is a project management tool that determines the longest sequence of dependent tasks and schedules them in a way that is most efficient, thereby identifying the critical path for the completion of a series of interrelated activities.

Question 2

_____ is a philosophy and a software and system development methodology that focuses on the development, use, and reuse of small, self-contained blocks of codes to meet the software needs of an organization.

Accepted Answer

Service-oriented architecture (SOA) is a software development model that emphasizes the use of discrete, reusable components (services) that can be easily integrated to create a comprehensive IT solution. This approach allows for flexibility, scalability, and the efficient reuse of existing services to meet various business requirements.

Question 3

Which of the following approaches for developing information systems increases the risk of leaking confidential information to competitors?

Accepted Answer

Outsourcing involves hiring third-party vendors to handle information systems tasks. This can increase the risk of confidential information being leaked to competitors, as external parties may not have the same level of commitment to protecting the company's data.

Question 4

In _____ conversion of the implementation phase of the systems development life cycle (SDLC), as each module of a new system is converted, the corresponding part of an old system is retired.

Accepted Answer

In the phased-in-phased-out conversion approach, the implementation of the new system is done in stages or modules. As each module of the new system is implemented, the corresponding module of the old system is retired. This method allows for a gradual transition and minimizes risk by not switching over to the new system all at once.

Question 5

During the _____ of the systems development life cycle (SDLC), an information system is operating, enhancements and modifications to the system have been developed and tested, and hardware and software components have been added or replaced.

Accepted Answer

During the maintenance phase of the SDLC, the system is in operation and ongoing support, including enhancements, modifications, and updates, are made to ensure the system continues to meet the organization's needs.

Question 6

In _____ conversion of the implementation phase of the systems development life cycle (SDLC), an old system is stopped and a new system is implemented.

Accepted Answer

In the plunge (also known as direct cutover) conversion method, the old system is completely stopped and the new system is implemented all at once. This approach can be risky if the new system has not been thoroughly tested.

Question 7

The _____ approach treats process and data independently and is a sequential approach that requires completing the analysis before beginning the design of information systems.

Accepted Answer

The structured systems analysis and design approach treats process and data independently and follows a sequential process, where analysis is completed before the design phase begins. This approach is traditional and contrasts with more integrated methods like object-oriented design.

Question 8

Which is a disadvantage of a request for proposal (RFP)?

Accepted Answer

A lengthy time frame for preparation is indeed a disadvantage of an RFP because it can delay the procurement process and make the RFP less appealing to both the issuing organization and potential vendors.

Question 9

Which is a similarity between agile methodology and extreme programming (XP)?

Accepted Answer

Both agile methodology and extreme programming (XP) focus on an incremental development process, where software is developed in small, manageable increments, allowing for frequent reassessment and adaptation.

Question 10

_____ can help reduce the backlog in producing information systems and improve flexibility in responding to users' information needs.

Accepted Answer

Self-sourcing allows users to develop their own information systems with little or no help from the IT department, reducing the backlog and improving flexibility in meeting their own information needs.

Question 11

Which statement is true of extreme programming (XP)?

Accepted Answer

Extreme Programming (XP) focuses on improving software quality and responsiveness to changing customer requirements by addressing issues through practices like continuous feedback, testing, and collaboration.

Question 12

_____ uses an iterative process that repeats the design, development, and testing steps as needed, based on feedback from users.

Accepted Answer

Rapid application development (RAD) uses an iterative process that involves repeated cycles of design, development, and testing, incorporating user feedback to refine and improve the application.

Question 13

_____ is a series of well-defined phases performed in sequence that serves as a framework for developing an information system or project.

Accepted Answer

The Systems Development Life Cycle (SDLC) is a series of well-defined phases performed in sequence that serves as a framework for developing an information system or project. It includes phases like planning, analysis, design, implementation, and maintenance.

Question 14

In _____ conversion of the implementation phase of the systems development life cycle (SDLC), an analyst introduces an information system in only a limited area of an organization, such as a division or department.

Accepted Answer

Pilot conversion involves implementing the new system in phases or in limited parts of the organization to reduce risks.

Question 15

Which of the following statements is true of pair programming?

Accepted Answer

Pair programming involves two programmers working together at one workstation on the same code, with one typing (the driver) and the other reviewing or navigating.

Question 16

With the _____  outsourcing approach, an organization chooses an outsourcing company in a neighboring country, such as when a U.S. organization chooses a company in Canada or Mexico.

Accepted Answer

Nearshore outsourcing involves selecting a company in a neighboring country, which is the case when a U.S. organization chooses a company in Canada or Mexico.

Question 17

In _____ conversion of the implementation phase of the systems development life cycle (SDLC), the old and new systems run simultaneously for a short time to ensure the new system works correctly.

Accepted Answer

Parallel conversion involves running both the old and new systems at the same time to verify the new system's functionality before fully transitioning to it. This approach helps in comparing the outputs of both systems to ensure the new system is working correctly.

Question 18

One shortcoming of rapid application development (RAD)is _____.

Accepted Answer

Rapid Application Development (RAD) focuses on quick prototyping and iterative delivery, which can sometimes result in a narrow focus on immediate application requirements. This narrow focus might limit the application's adaptability and scalability in the future, as it may not consider broader or future development needs adequately.

Question 19

_____ is a method for developing software applications and information system projects in which a project is divided into smaller functions and developers cannot go on to the next phase until the current phase is finished.

Accepted Answer

Extreme programming is a method where development is divided into small phases, and each phase must be completed before moving to the next.

Question 20

Which is a difference between the systems development life cycle (SDLC)and extreme programming (XP)?

Accepted Answer

The answer of Which is a difference between the systems...
