Question 2

Which of the following functions does the version control software perform?
A) allowing developers to interact with different versions of the system simultaneously
B) allowing developers to track different versions of news feeds once it is viralled into a network
C) allowing developers to write over one another's files which helps to efficiently integrate data
D) allowing developers to track code versions acting like a library with checkout procedures

Accepted Answer

Version control software is mainly used for tracking code versions as it acts like a library with checkout procedures. Option A is also a function of version control software, but it is not the best choice as it only covers one of the functions. Options B and C are incorrect as version control software is not used for tracking news feeds and does not allow developers to write over each other's files.

Question 3

The ________ offers customizable dashboards so that developers can see at a glance how a process is coming along, which activities they need to complete today, and help keep abreast of all aspects of their process.
A) project- and issue-tracking software
B) mind mapping software
C) keystroke logging software
D) waterfall software

Accepted Answer

Project and issue-tracking software are designed to help developers manage and track their work. Customizable dashboards are a key feature of this software, allowing developers to see an overview of their current tasks and progress, as well as any issues that need attention. Mind mapping software and keystroke logging software do not offer these features, and waterfall software is a type of project management methodology rather than a specific software solution.

Question 4

Johanna Taylor, a developer at the newly established Leo Technologies, is developing a Web site for the company. Which of the following phases is she working on if she is making decisions on increased bandwidth, size, and capacity issues which will help handle growing amounts of visits by clients and customers?
A) testing
B) design
C) maintenance
D) implementation

Accepted Answer

Johanna is working on the design phase, specifically the infrastructure design, to ensure that the website has the necessary bandwidth, size, and capacity to handle increased amounts of traffic. This is typically done during the planning and design phases of website development. Testing is focused on ensuring that the website functions properly, maintenance is ongoing work to ensure the website continues to function and stay up-to-date, and implementation is the actual building and deployment of the website.

Question 5

A use case diagram is used to indicate ________.
A) how screen layouts are created and developed
B) how users can switch from one operating system to another
C) how database tables are interconnected with one another
D) how different types of users will interact with the system

Accepted Answer

Use case diagrams are used to specify the interactions between users and a system, and how different actors (types of users) will interact with the system. They do not cover screen layouts, operating system switching, or database interconnections.

When Joshua is converting the design into an operational information system, it means that he is implementing or developing the software. Hence, the software is currently in the development phase.

Question 7

Which of the following functions does a project- and issue-tracking software perform?
A) comparing and analyzing a project with a competitiors' project in the market
B) tracking versions of the code and acting like a library with checkout procedures
C) allowing customers to view the status of a product right before its launch in the market
D) maintaining a complete history of project activity, including dates and tasks assigned

Accepted Answer

A project- and issue-tracking software maintains a complete history of project activity, including dates and tasks assigned. Option A is incorrect because project tracking software does not compare or analyze projects with competitors. Option B is incorrect because tracking code versions is a version control system's function, not that of project-tracking software. Option C is incorrect because software cannot show the status of a product before it is launched; that is the marketing department's function.

Question 8

Which of the following is used to handle increased Web site visits?
A) new hard drives
B) increased bandwidth
C) USB drives
D) extended hard drives

Accepted Answer

Increased bandwidth is used to handle increased Web site visits, as it allows more data to be transmitted at once, thus reducing the likelihood of slow or unresponsive website loading times. New hard drives, USB drives, and extended hard drives are not directly related to managing website traffic.

Question 9

The type of testing which involves end users performing final testing to determine whether the project is complete as specified is known as ________.
A) stress testing
B) parallel testing
C) unit testing
D) acceptance testing

Accepted Answer

Acceptance testing is the type of testing which involves end users performing final testing to determine whether the project is complete as specified. Stress testing is a type of testing that evaluates a system or component at or beyond the limits of its anticipated or specified workload. Parallel testing is a software testing type that involves both the legacy system and the new system to run simultaneously to compare results. Unit testing is a testing technique where individual units or components of a software application are tested separately from the rest of the application to ensure they are functioning as intended.

Question 10

Which of the following should be undertaken in a design phase?
A) defining the business need for a project
B) keeping in mind end users with disabilities
C) conducting risk analysis for the project
D) estimating return on investment

Accepted Answer

During the design phase, it's important to consider end users with disabilities to ensure the product is accessible and inclusive.

Question 11

Designers use the unified modeling language to ________.
A) standardize graphics symbols and notations to improve communication and clarity
B) establish clarity of audio models of object-oriented software-intensive systems
C) target an ambiguous specification and description of the behavior of distributed systems
D) design information systems by depicting them using object and process models

Accepted Answer

UML (Unified Modeling Language) is used to standardize graphical symbols and notations to improve communication and clarity in the design of object-oriented systems.

Question 12

Which of the following is the primary goal of the development phase?
A) analyzing and documenting what a system should do for the business
B) translating the requirements definition document into a workable design
C) converting a design into a fully operational information system
D) calculating return on investment for the business project

Accepted Answer

The primary goal of the development phase is to convert a design into a fully operational information system. This involves writing and testing code, configuring hardware and software components, and integrating various subsystems to create a coherent and functional system. While analysis and documentation are important activities in the earlier stages of the system development lifecycle, the primary focus of the development phase is on building the system itself. Calculating return on investment (ROI) may be a consideration throughout the project, but it is not the primary goal of any one phase.

Question 13

Which of the following best describes a service oriented architecture?
A) systems created with mutually dependent software components
B) systems created from interconnected subsets of its software components
C) systems assembled from relatively independent software components
D) systems with overlapping components that are used in slow moving companies

Accepted Answer

A service oriented architecture (SOA) is a way of designing software systems as a collection of independent, modular services that communicate with each other over a network. These services are built to perform specific functions and can be used by other services or applications. The emphasis is on loose coupling and maximum reusability of software components, allowing for flexible and scalable systems. Option A is incorrect because mutually dependent components go against the principles of loose coupling and independence. Option B is incorrect because interconnected subsets still imply a degree of tight coupling. Option D is incorrect because overlapping components may lead to redundancy and inconsistency.

Question 14

Testing is a part of the ________ phase.
A) analysis
B) development
C) design
D) planning

Accepted Answer

Testing is a part of the development phase, which involves writing and implementing code to create the software or application. Testing is done during this phase to identify and resolve any defects or issues before the software is released to the end user.

Question 15

________ is the best choice when a system supports common business functions, such as financial or human resource management.
A) Promoting
B) Selling
C) Building
D) Buying

Accepted Answer

Buying a pre-built system that supports common business functions, such as financial or human resource management, can be more efficient and cost-effective than building or promoting a custom solution. Selling is not a relevant choice in this context.

Question 16

The ________ phase is a technical blueprint for the whole system which captures all aspects of how a system's components will function together to accomplish goals, using descriptions and models.
A) maintenance
B) design
C) testing
D) implementation

Accepted Answer

The design phase is specifically focused on creating a technical blueprint for the system, including how all components will work together. The other phases (maintenance, testing, and implementation) come later in the process.

Question 17

Service oriented architecture is most likely to be used by companies that are ________ in nature.
A) agile
B) static
C) sluggish
D) obsolete

Accepted Answer

Service oriented architecture (SOA) is a software design approach where application components are designed to provide services to other components through a communication protocol over a network. This approach is more flexible and adaptable, making it suitable for companies that are agile and constantly changing to meet developing customer needs. Companies that are static, sluggish or obsolete would not find SOA useful as they are unlikely to require the flexibility and adaptability that SOA provides.

Question 18

________ involves programmers checking the functionality of small modules of code during the development phase.
A) Unit testing
B) System testing
C) Integration testing
D) Acceptance testing

Accepted Answer

Unit testing involves testing small units or modules of code during the development phase to ensure their functionality. This helps to catch and fix errors early in the development process, making it easier to manage and maintain the codebase. System testing, integration testing, and acceptance testing are all different types of testing that occur at later stages in the development cycle.

Question 19

________ is a peer review process in which programmers familiar with the project and the development environment check over one another's work to ensure it is well documented and properly written.
A) Double-blind review
B) Single-blind review
C) Adversarial review
D) Code review

Accepted Answer

The process described is commonly known as a code review, in which programmers review each other's work to ensure it meets coding standards and is free of errors. Option A, double-blind review, refers to a review process in which both the reviewer and the person being reviewed are anonymous to each other. Option B, single-blind review, refers to a review process in which the reviewer is anonymous to the person being reviewed. Option C, adversarial review, is a process where developers simulate attacks on a codebase to find vulnerabilities.

Question 20

A general rule of thumb is that an organization should consider the buy approach when ________.
A) license software meets 75 to 80 percent of its requirements
B) customer demands emphasize on customization of a product
C) organizations need to retain the same business processes
D) softwares need to fit enterprise architecture perfectly

Accepted Answer

When the licensed software meets a significant portion of an organization's requirements, it makes sense to use the buy approach as it can save time and resources compared to building a custom solution.
