Question 1

Tessa asks the 10 members of her testing team to each load their 20 testing scripts to ensure that the modified information system is operating as intended.What type of testing is that?

Accepted Answer

Volume testing involves testing the system with a large amount of data or transactions, which is consistent with the scenario described in the question where each team member is tasked with loading 20 testing scripts. Unit testing involves testing individual units or modules of code, system testing involves testing the entire system, and integration testing involves testing the interaction between different components of the system. Therefore, volume testing is the best choice for the given scenario.

Question 2

One advantage of using cloud computing is that it is easier management of information systems because everything is in one place on the Internet.

Accepted Answer

Cloud computing allows for centralized management of information systems, making it easier to access and manage data from one location on the Internet.

Question 3

What type of testing involves testing an incomplete or early version of the system?

Accepted Answer

Alpha testing involves testing an incomplete or early version of the system. Beta testing is done with a complete version of the system that is released to a select group of users for feedback. Unit testing is done on individual units or components of the system, and volume testing involves testing the system with large amounts of data.

Question 4

Which of the following activities is included in site preparation?

Accepted Answer

Site preparation involves tasks like installing special wiring and air conditioning to ensure the environment is suitable for the new system.

Question 5

What approach is a form of system initiation with a specific group of users?

Accepted Answer

The pilot start-up approach involves implementing the new system with a specific group of users before rolling it out to the entire organization. This allows for testing and feedback before full implementation, reducing the risk of failure and allowing for adjustments to be made. The other approaches involve implementing the new system for all users at once, which can be more risky and overwhelming. Therefore, the pilot start-up approach is the best choice.

Question 6

What term refers to the activity to enable the new system so it is up and running efficiently with the relevant data from the previous system?

Accepted Answer

Data conversion refers to the process of transferring data from the previous system to the new system so that it can be used efficiently. This includes mapping the existing data to match the new system's data structure and testing to ensure the accuracy of the transferred data. Data deployment refers to the process of installing software and hardware in a system, but it does not necessarily involve data transfer or conversion. Data testing refers to the quality assurance process to ensure that the data is accurate and complete. Data mapping is a part of data conversion, where data from the old system is mapped to match the new system's structure. Therefore, the best choice is D.

Question 7

Which of the following denotes a software development technique that allows programmers to develop programs that can run on computer systems having different hardware and operating systems?

Accepted Answer

The answer of Which of the following denotes a software...

Question 8

Security is not an important consideration of logical design, but comes later in the systems development process.

Accepted Answer

Security should be considered as an important aspect of logical design as it helps ensure that the system is secure from the start, rather than trying to add security measures later on in the development process.

Question 9

Which one of the following terms accurately defines the process to help managers, decision makers, employees, stakeholders, and others to be ready for the new system?

Accepted Answer

User preparation refers to the process of ensuring that managers, decision makers, employees, stakeholders, and others are ready and prepared for the new system. This includes communicating the benefits of the new system, addressing concerns and questions, and providing the necessary resources to ensure a smooth transition. While start-up, user acceptance, and training are all important elements of implementing a new system, they do not accurately define the process of user preparation.

Question 10

Two advantages of cloud computing are improved security and increased availability of critical applications.

Accepted Answer

The answer of Two advantages of cloud computing are improved...

Question 11

The logical design phase refers to how the tasks are accomplished, including how the components work together and what each component does.

Accepted Answer

The logical design phase refers to the high-level abstract representation of the system's functionality, without including specific implementation details of how the components work together or what each component does. The physical design phase is where these specifics are determined.

Question 12

Which of the following is a characteristic of a slipstream upgrade to a system?

Accepted Answer

A slipstream upgrade involves making changes to a system without notifying end users in advance. It is often done to address a critical bug or security vulnerability. However, because it is a rushed process, it can result in unintended consequences such as creating new bugs or causing compatibility issues with other software. It may not necessarily represent a significant change in how the system operates, and it is not always a major upgrade.

Question 13

Many organizations are turning to object-oriented development because of its increased flexibility.

Accepted Answer

Object-oriented development allows for greater flexibility in programming, as it allows for classes and objects to be easily modified and reused in different parts of the program. This can lead to more efficient and adaptable code.

Question 14

Which of the following is a characteristic of a legacy system?

Accepted Answer

A legacy system is typically an old system that has been in use for a long time, and may have undergone multiple patches or modifications over time. It may have outdated technology, and may be difficult or expensive to maintain, upgrade or integrate with newer systems.

Question 15

During physical design, the characteristics of the hardware, software, database, telecommunications, personnel, and procedures and control specifications must be detailed.

Accepted Answer

During physical design, all aspects of the system including hardware, software, database, telecommunications, personnel, and procedures and control specifications are detailed in order to ensure that the final product meets the intended specifications and requirements.

Question 16

The independent testers have just completed their testing of the codes of the individual developers to ensure that there is no impact to the other functional areas that have already been tested.What type of testing is that?

Accepted Answer

The answer of The independent testers have just completed their...

Question 17

What process requires testing all related systems together?

Accepted Answer

Integration testing is the process of testing all related systems together to ensure that they work together as expected. This is typically done after unit testing, and before acceptance testing, to ensure that any issues with the way different parts of the system function together are identified and resolved before the system is released to users.

Question 18

Which of the following is a characteristic of user documentation?

Accepted Answer

User documentation is meant for end-users or individuals who are not programmers or IT experts. It aims to teach users how to interact with the software, how to execute certain functions, and how to optimize the usage of the program. Therefore, D is the correct choice as it describes the purpose of user documentation. A is incorrect as it is associated with operator manuals, B relates to technical documentation, and C pertains to source code comments.

Question 19

The developers have just completed their coding of the system and each developer is testing each of the components that he or she has written.What type of testing is that?

Accepted Answer

This is unit testing, as each developer is testing the individual component that they have written.

Question 20

Which of the following is a key system design task?

Accepted Answer

Development of an RFP (Request for Proposal) is a key system design task as it clearly outlines the requirements, scope, and objectives of the project to potential vendors who can submit proposals for the system design. This helps in selecting the right vendor who can meet the requirements of the organization. Hardware acquisition, user preparation, and site preparation are important tasks but not necessarily specific to system design.
