Question 1

An object wrapper creates an application program interface (API) to a legacy system, enabling object-oriented systems to interact with it.

Accepted Answer

An object wrapper provides an API for object-oriented systems to communicate with legacy systems.

Question 2

Some benefits of outsourcing are that the service provider may be more experienced in the technology that would greatly benefit your organization and may have more experienced programmers.

Accepted Answer

Outsourcing to a service provider who specializes in a certain technology or skillset and has more experienced programmers can bring benefits to an organization.

Question 3

A package is a logical grouping of UML elements.

Accepted Answer

A package in UML is used to group together related elements such as classes, interfaces, and other packages. The purpose of a package is to provide organization and structure to the model, making it easier to understand and maintain.

Question 4

There are three primary types of outsourcing contracts: 1) time and arrangements, 2) variable-price, and 3) value added.

Accepted Answer

The three primary types of outsourcing contracts are 1) fixed price, 2) time and materials, and 3) cost-plus.

Question 5

A package diagram is a class diagram that shows only packages and classes.

Accepted Answer

A package diagram is a type of diagram in UML that shows how packages (groups of related classes) are organized and interact within a system, not just the packages and classes themselves.

Question 6

It is much less efficient to buy packaged software that has already been created, tested, and proven than to build a system from scratch.

Accepted Answer

Buying packaged software can be much more efficient in terms of time, cost, and resources compared to building a system from scratch. Packaged software has already been tested, debugged, and proven to work, which can save a lot of time and effort. Building a system from scratch requires a dedicated team of developers, testers, and resources, which can be costly and time-consuming.

Question 7

Pirate Adventures, Inc., a company that owns and operates hotels in tropical locations, is interested in replacing the 15-year-old room reservation system in all of its hotels. Custom development would be the best design strategy.

Accepted Answer

It is not clear from the information provided why custom development would be the best design strategy. It is possible that an off-the-shelf solution could meet the company's needs and be more cost-effective. More information is needed to make a determination about the best design strategy.

Question 8

Which one in the following is NOT a factor for selecting a design strategy?
A) Business need
B) In-house experience
C) Project skills
D) Time frame
E) Software quality

Accepted Answer

All the other factors (business need, in-house experience, project skills, and time frame) would be important considerations when selecting a design strategy. However, software quality is not necessarily a factor in selecting a design strategy - rather, software quality would be an important outcome that the design strategy should aim to achieve.

Question 9

It can be much more efficient to buy programs that have already been created, tested, and proven, and a packaged software system can be bought and installed in a relatively short period of time compared with a custom system.

Accepted Answer

Packaged software systems are pre-built and pre-tested software applications that are available for purchase and installation. These systems are designed to meet the needs of a broad range of users and can be installed quickly and easily compared to custom systems that need to be developed from scratch. Packaged software systems are often more cost-effective and efficient than custom systems, as they have already been proven to work and often include features and functionality that have been refined over time based on user feedback.

Question 10

Max has been a project manager for 10 years and is considered one of the best in his department of well qualified IS professionals. The approval committee is considering the approval of a new unique Internet system that could possibly catapult the firm ahead of all of the competition. Buying a packaged system would be the best design strategy.

Accepted Answer

The statement "Buying a packaged system would be the best design strategy" is not necessarily true. It depends on the specific needs and requirements of the project, and whether a packaged system can meet those needs effectively. As a project manager, Max should carefully evaluate all possible design strategies and choose the one that is most appropriate for the project goals and constraints.

Question 11

The layer that would include the classes that would interact with middleware applications is the physical architecture layer.

Accepted Answer

The answer of The layer that would include the classes...

Question 12

The purpose of the design phase is to create a blueprint for the new system.

Accepted Answer

The design phase is where the system requirements are analyzed, and a plan is created to develop the new system. The outcome of this phase should be a blueprint or design document that outlines how the new system will function and how it will meet the user's needs.

Question 13

A(n) ______ matrix can be used to organize the pros and cons of the design alternatives so that the best solution will be chosen in the end.
A) alternative
B) cost-benefit
C) feasibility
D) design
E) evaluation

Accepted Answer

The answer of A(n) ______ matrix can be used to...

Question 14

Many project teams believe that packaged software is the best way to create a system because they have complete control over the way the system looks and functions, and they can be flexible and creative in the way they solve business problems.

Accepted Answer

This statement is false. Packaged software, such as off-the-shelf solutions, pre-built modules, or third-party software, often have limitations on customization, and project teams may have to work within the constraints of the software's functionality. However, using packaged software can save time and resources in development and testing, and may be a cost-effective solution for certain business needs.

Question 15

The decision on which design strategy to use depends on _____.
A) how unique the business need is
B) the expertise of the project manager
C) the urgency of the project
D) the amount of in-house experience
E) all of the above

Accepted Answer

The decision on which design strategy to use can depend on multiple factors including the uniqueness of the business need, the expertise of the project manager, the urgency of the project, and the amount of in-house experience. Therefore, all of the above factors can influence the decision.

Question 16

Custom development allows developers to be flexible and creative in the way they solve business problems.

Accepted Answer

Custom development provides developers with the ability to think outside the box and tailor solutions to meet unique business needs. This approach is more flexible and allows for more creative solutions compared to using pre-built or off-the-shelf products.

Question 17

Which one in the following is a development strategy?
A) Rational Unified development
B) offshore development
C) packaged software
D) Agile development
E) Rapid prototyping

Accepted Answer

The answer of Which one in the following is a...

Question 18

There are three design strategies: 1) developing a custom application in-house, 2) hiring a consultant, and 3) relying on an external vendor, developer, or service provider to build the system.

Accepted Answer

The answer of There are three design strategies: 1) developing...

Question 19

Which the following class should be designed in layer Foundation.
A) Date
B) DataInputStream
C) Button
D) Studnent
E) URLConnection

Accepted Answer

The class Date belongs to the core domain model and is required by many other classes in different layers. It can be used by the higher layers such as Application and Presentation, so it should be located in the Foundation layer.

Question 20

Which one in the following is NOT a layer of a software architecture.
A) Foundation
B) Problem Domain
C) Data management
D) Data structure
E) Human-computer Interface

Accepted Answer

While data management and data structure can both be valid layers of a software architecture, "data structure" is not typically considered a distinct layer in and of itself. Instead, it may be considered a component of a broader layer such as data management or application logic.
