A)Extreme programming (XP)
B)Rapid application development (RAD)
C)Service-oriented architecture (SOA)
D)Joint application design (JAD)

Accepted Answer

This description matches the Agile methodology called Extreme programming (XP), which emphasizes iterative development, frequent testing, and continuous integration. XP breaks down the project into smaller pieces and requires developers to complete each phase before moving on to the next one.

Question 3

Identify a disadvantage of a request for proposal (RFP).
A)A lengthy time frame makes a request for proposal less appealing.
B)If the time involved in evaluating proposals is short,it makes the request for proposal complex.
C)In a request for proposal,every vendor gets different information resulting in unfair bids.
D)In a request for proposal,different vendors have different deadlines for submitting bids.

Accepted Answer

The RFP process can be time-consuming, involving detailed preparation, distribution, and evaluation, which can delay decision-making and project initiation.

Question 4

Which of the following increases the risk of leaking confidential information to competitors?
A)Insourcing
B)Outsourcing
C)Self-sourcing
D)Greenfield venturing

Accepted Answer

Outsourcing involves hiring external parties to handle certain aspects of a company's operations, which may include access to confidential information. This increases the risk of leaking confidential information to competitors. Insourcing, self-sourcing, and greenfield venturing do not necessarily involve external parties and may not increase the risk of leaking confidential information to competitors.

Question 5

During the implementation phase of the systems development life cycle (SDLC),in _____,the old and new systems run simultaneously for a short time to ensure the new system works correctly.
A)parallel conversion
B)phased-in-phased-out conversion
C)plunge conversion
D)pilot conversion

Accepted Answer

Parallel conversion involves running the old and new system simultaneously for a short period to ensure the new system is working correctly. This is considered the safest and most reliable form of conversion as it minimizes the risk of system failure or data loss.

Question 6

With _____,an organization chooses an outsourcing company in the same country.
A)onshore outsourcing
B)nearshore outsourcing
C)offshore outsourcing
D)farshore outsourcing

Accepted Answer

Onshore outsourcing involves choosing an outsourcing company in the same country or a nearby location. This is often a better choice for organizations that prefer to work with companies that share similar language and culture. Additionally, onshore outsourcing can provide quicker response times and easier access to resources, making it a more convenient option for some organizations.

Question 7

During the implementation phase of the systems development life cycle (SDLC),in _____,as each module of a new system is converted,the corresponding part of an old system is retired.
A)parallel conversion
B)phased-in-phased-out conversion
C)plunge conversion
D)pilot conversion

Accepted Answer

Phased-in-phased-out conversion is a type of conversion approach in which each module of a new system is converted one at a time, and the corresponding part of the old system is retired simultaneously. This allows for a gradual transition from the old system to the new system, which minimizes the risks associated with the conversion process. This approach can also allow for testing and refinement of the new system as each module is implemented.

Question 8

During the _____ of the systems development life cycle (SDLC),a solution is transferred from paper to action,and a team configures the system and procures components for it.
A)analysis phase
B)design phase
C)implementation phase
D)maintenance phase

Accepted Answer

The implementation phase is focused on putting the solution into action, configuring the system, procuring necessary components, and integrating components. It follows the design phase, where the solution is documented and planned out on paper. The analysis phase is focused on identifying problems and needs, and the maintenance phase comes after implementation and focuses on ongoing support and enhancements.

Question 9

A _____ shows users how a particular task that was not technically feasible can be done.
A)proof-of-concept prototype
B)computer-aided prototype
C)requirements-based prototype
D)phased-in-phased-out prototype

Accepted Answer

A proof-of-concept prototype is specifically designed to demonstrate the feasibility of a concept or idea, and how it can be implemented or accomplished. It is used to test and prove that a particular task or process can be achieved or carried out using a specific technology, methodology or approach. Therefore, it is the best choice for showing users how a task that was previously not possible can now be done. Computer-aided prototypes, requirements-based prototypes, and phased-in-phased-out prototypes, on the other hand, are each designed for different purposes, such as refining or finalizing a product design or testing specific functionality, and may not be as effective for demonstrating feasibility.

Question 10

With _____,an organization chooses an outsourcing company in any part of the world (usually a country farther away than a neighboring country),as long as it can provide the needed services.
A)onshore outsourcing
B)nearshore outsourcing
C)offshore outsourcing
D)farshore outsourcing

Accepted Answer

Offshore outsourcing involves choosing an outsourcing company located in a country farther away than a neighboring country. Therefore, this is the best choice for the given scenario. Onshore outsourcing involves choosing a company within the same country, while nearshore outsourcing involves choosing a company located in a neighboring country. Farshore outsourcing is not a commonly used term.

Question 11

With _____,an organization chooses an outsourcing company in a neighboring country,such as when a U.S.organization chooses a company in Canada or Mexico.
A)onshore outsourcing
B)nearshore outsourcing
C)offshore outsourcing
D)farshore outsourcing

Accepted Answer

Nearshore outsourcing refers to outsourcing to a neighboring country, which offers several advantages such as similar time zones, cultural similarities, and lower language barriers. This option is often preferred over offshore outsourcing, which involves choosing a company located in a distant country. Onshore outsourcing involves choosing a company located within the same country, while farshore outsourcing is not a commonly used term in outsourcing.

Question 12

Identify a true statement of the Critical Path Method (CPM).
A)In such a network,the critical path takes the shortest time to be completed.
B)The technique works by determining the critical path for interrelated activities with zero slack time.
C)Activities that are on the critical path are flexible and can be delayed.
D)A delay in the activities of a project can be ignored without considering additional resources.

Accepted Answer

The Critical Path Method works by determining the critical path for interrelated activities with zero slack time, meaning that any delay in the critical path will directly cause a delay in the entire project schedule. Activities on the critical path cannot be delayed without affecting the project completion date. Options A, C, and D are all false statements about the Critical Path Method.

Question 13

_____ 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.
A)Extreme programming (XP)
B)Rapid application development (RAD)
C)Service-oriented architecture (SOA)
D)Joint application design (JAD)

Accepted Answer

The philosophy and methodology described in the statement is Service-oriented Architecture (SOA), which emphasizes the use of small, modular components (known as services) to build larger software systems. Extreme programming (XP) is a methodology focused on iterative and collaborative development, Rapid application development (RAD) emphasizes rapid prototyping and development cycles, and Joint application design (JAD) is a collaborative design methodology.

Question 14

_____ helps reduce the backlog in producing information systems and improve flexibility in responding to users' information needs.
A)Subcontracting
B)Outsourcing
C)Self-sourcing
D)Crowdsourcing

Accepted Answer

Self-sourcing allows users to create their own information systems without relying on IT departments, reducing the backlog for IT and providing flexibility for users to meet their specific needs. Subcontracting and outsourcing involve hiring external parties to perform IT tasks, while crowdsourcing involves obtaining input and ideas from a large group of individuals.

Question 15

_____ uses an iterative process that repeats the design,expansion,and testing steps as needed,based on feedback from users.
A)Extreme programming (XP)
B)Rapid application development (RAD)
C)Service-oriented architecture (SOA)
D)Joint application design (JAD)

Accepted Answer

The iterative process of repeating design, expansion, and testing based on user feedback describes the Rapid Application Development (RAD) methodology. Extreme Programming (XP) also involves iterative development, but emphasizes teamwork and communication among the development team, while Service-Oriented Architecture (SOA) refers to an architectural approach for building applications, not a specific development process. Joint Application Design (JAD) is a collaborative approach for gathering user requirements, but does not necessarily involve an iterative development process.

Question 16

During the implementation phase of the systems development life cycle (SDLC),in _____,the analyst introduces an information system in only a limited area of an organization,such as a division or department.
A)parallel conversion
B)phased-in-phased-out conversion
C)plunge conversion
D)pilot conversion

Accepted Answer

During the implementation phase of the SDLC, in pilot conversion, the analyst introduces an information system in only a limited area of an organization, such as a division or department. This allows for testing and refinement of the system before it is rolled out to the entire organization. Therefore, D is the best choice. A, B, and C do not match the description provided.
