Question 1

Which of the following is a component of the Maintenance phase of the SDLC?

Accepted Answer

The Maintenance phase involves ongoing updates and support for the system, including new versions or releases of software with associated updates to documentation, training, and support. The other options listed are components of earlier phases in the SDLC (Design and Planning).

Question 2

The life cycle can be thought of as a linear process in which the end of the useful life of one system leads to the beginning of another project that will develop a new version or replace an existing system altogether.

Accepted Answer

The life cycle is often viewed as a circular or iterative process, where the end of the useful life of one system can lead to feedback, updates, and improvements, rather than just the start of a completely new project. This allows for continuous improvement and adaptation over time.

Question 3

An integrated and standard database called a ________ is the common method for providing product and tool integration,and has been a key factor in enabling CASE to more easily manage larger,more complex projects and to seamlessly integrate data across various tools and products.

Accepted Answer

A repository is a common database used for storing and managing data in a standardized manner. It is commonly used in CASE (Computer-Aided Software Engineering) environments to provide product and tool integration, and to seamlessly integrate data across different tools and products. It enables easier management of larger, more complex projects by providing a single source of truth for all the artifacts and data related to the project. Workbooks, project dictionaries, and methodologies are all different concepts and not directly related to the use of a repository in CASE.

Question 4

Which of the following CASE tools is useful in the analysis phase of the SDLC?

Accepted Answer

Diagramming tools, such as data flow diagrams or use case diagrams, are commonly used in the analysis phase of the SDLC to visually represent the system or business processes being analyzed. Report generators, form generators, and documentation generators are more commonly used in later development phases.

Question 5

A specialized systems development life cycle is mainly required for ________.

Accepted Answer

A specialized systems development life cycle is required for organizations that do not need all phases of the SDLC or need to modify those phases. In other words, it is specifically designed for organizations that have unique requirements and cannot follow the generic SDLC model. Therefore, options A and B are incorrect as they imply that the organization needs only a limited number of phases, not a specialized SDLC. Option C is also incorrect since not all organizations require a specialized SDLC.

Question 6

The part of the design process that is independent of any specific hardware or software platform is referred to as logical design.

Accepted Answer

Logical design focuses on creating a conceptual model that defines the functionality and interactions of system components, and is typically not constrained by the limitations or requirements of specific hardware or software platforms.

Question 7

Which of the below is NOT a true statement regarding the SDLC?

Accepted Answer

The SDLC is a systematic and structured approach to software development that consists of well-defined phases and a clear relationship between them. However, it is not typically considered a rapid method to prototype and develop an application, as it prioritizes thorough planning and testing before implementation.

Question 8

The systems development life cycle (SDLC)is a rare methodology for systems development in many organizations

Accepted Answer

The Systems Development Life Cycle (SDLC) is a widely used and recognized process for planning, creating, testing, and deploying an information system, with numerous methodologies such as Agile, Waterfall, and Spiral being common in various organizations.

Question 9

Attempts to make systems development less of an art and more of a science are usually referred to as ________.

Accepted Answer

Systems engineering is the field of engineering that focuses on the design, integration, and operation of complex systems. It utilizes a structured and systematic approach to develop, design, operate, and maintain systems. This approach aims to make systems development less of an art and more of a science by emphasizing the use of methods, tools, and best practices. Computer-aided software engineering (CASE) and computer engineering are related fields, but they do not have the same focus as systems engineering. Systems development is a general term that encompasses many different approaches and methodologies, including systems engineering.

Question 10

Which of the following CASE tools is useful in the project initiation and planning phase of the SDLC?

Accepted Answer

Documentation generators are useful in the project initiation and planning phase of the SDLC as they can assist in creating project proposals, feasibility studies, requirements documents, and other important project planning documents. Diagramming, report generators, and form generators may also be useful tools in other phases of the SDLC, but they are not the best choice for the project initiation and planning phase.

Question 11

Which of the following is a drawback of the traditional waterfall SDLC approach?

Accepted Answer

The traditional waterfall SDLC approach locks users into requirements, which means that changes are difficult to make once the project has progressed to the next stage. This can result in a product that does not meet the needs of the end-users.

Question 12

Most organizations found it difficult to use the systems development methodology to develop and support their information systems.

Accepted Answer

The answer of Most organizations found it difficult to use...

Question 13

Which of the following is NOT a general type of CASE tools?

Accepted Answer

Debuggers are not considered a general type of CASE tool. Diagramming tools, display and report generators, and analysis tools are all commonly recognized types of CASE tools.

Question 14

Which of the following are delivered after the completion of analysis phase?

Accepted Answer

The answer of Which of the following are delivered after...

Question 15

The third phase in the SDLC is planning and in this phase the analyst thoroughly studies the organization's current procedures and the information systems used to perform organizational tasks.

Accepted Answer

The third phase in the SDLC is typically the Design phase. The Planning phase is actually the first phase, where the project's feasibility, scope, and objectives are determined.

Question 16

Which of the following is NOT a criticism of the traditional waterfall SDLC approach?

Accepted Answer

The criticism of the traditional waterfall SDLC approach includes B, C, and D. Users being locked into requirements means that they are unable to change their requirements once the development process starts. The role of customers being narrowly defined means that customers may not have a clear idea of what they want or need, which can lead to misunderstandings or errors. Giving intangible processes hard and fast dates can lead to delays or backlogs if the deadlines are not achievable. However, there is no criticism regarding prototypes not working properly in the traditional waterfall SDLC approach.

Question 17

As part of logical design,analysts design the various parts of the system to perform the physical operations necessary to facilitate data capture,processing,and information output.

Accepted Answer

In the logical design phase, analysts focus on defining the structure and features of the system, including data requirements, relationships, and processes, without considering the physical implementation details. The physical design phase, not the logical design phase, addresses the actual implementation and how the system will perform its operations.

Question 18

Which of the following is one of three key principles shared by the Agile Methodologies?

Accepted Answer

One of the key principles of Agile Methodologies is a focus on self-adaptive processes. This involves a willingness to adapt and change processes as needed throughout the development cycle, rather than sticking strictly to a predetermined plan. The other principles are a focus on individuals and interactions over processes and tools, and a focus on delivering working software frequently.

Question 19

In the SDLC,it is not possible to complete some activities in one phase in parallel with some activities of another phase.

Accepted Answer

In the SDLC, it is common to have overlapping activities across phases, allowing for concurrent work to take place. This approach is known as iterative development and can lead to a more efficient and effective process by allowing feedback and adjustments to be made throughout the development cycle.

Question 20

Maintenance is a separate phase and not the repetition of the other life cycle phases to study and implement the needed changes.

Accepted Answer

Maintenance often involves revisiting and repeating earlier phases of the life cycle (such as design, development, and testing) to implement necessary changes, rather than being a completely separate phase.
