Question 1

A preliminary design,a detail design,and a report on the work done on these are created during the ________ phase of the SDLC.

Accepted Answer

The preliminary design and detail design are created during the systems design phase of the SDLC. This phase comes after the systems analysis phase, where requirements are gathered and analyzed, and before the systems implementation phase, where the actual implementation of the system takes place. The report on the work done on these designs would also be created during the systems design phase. Therefore, the best choice is B.

Question 2

In the SDLC's third phase,the way in which a proposed information system will deliver the general abilities described in the preliminary design is described in the ________ design.

Accepted Answer

The detail design phase of the SDLC is where the proposed information system is designed in detail, including how it will deliver the general abilities described in the preliminary design. The detail design includes defining the system architecture, designing data structures, and specifying hardware and software requirements. Choices A, B, and C are other techniques or tools used in different phases of the SDLC.

Question 3

Using workstations,CASE tools,UML,and other software to build working models of system components so that they can be quickly tested and evaluated is called ________.

Accepted Answer

Building working models using software and tools to quickly test and evaluate system components is known as prototyping. Systems design involves creating detailed plans for the system, while systems analysis involves analyzing the requirements and identifying solutions. Systems implementation involves putting the system into use.

Question 4

In Phase 5 of the SDLC,if a company simply quits using the old system and begins using the new one,this is what type of system conversion plan?

Accepted Answer

This type of system conversion plan is called direct implementation, where the new system is implemented and the old system is abandoned without any transition period or parallel operation. This can be a risky strategy as there is no backup system in case of any unexpected issues, but it can also be the most efficient and cost-effective option.

Question 5

In the SDLC's third phase,the general functional capabilities of a proposed information system are described in the ________ design.

Accepted Answer

The third phase of the SDLC is the design phase, and within this phase, the preliminary design describes the general functional capabilities of the proposed information system. Option A, detail design, is a later stage in the design phase where more specific details are fleshed out. Option B, prototype, is a potential output of the design phase but is not synonymous with the preliminary design. Option C, UML (Unified Modeling Language), is a tool that can be used during the design phase but is not the actual design itself.

Question 6

What kind of analytical tools allows a systems analyst to present graphic representations of a system?

Accepted Answer

Modeling tools allow a systems analyst to present graphic representations of a system through visual diagrams such as flowcharts, data flow diagrams, and entity-relationship diagrams. Replica, copy, and duplication are not relevant analytical tools for this purpose.

Question 7

An information specialist who performs systems analysis,design,and implementation is a(n)________.

Accepted Answer

A systems analyst is specifically trained to perform systems analysis, design, and implementation. The other choices may not have the same level of expertise or may focus on different aspects of analysis.

Question 8

What is a six-phase problem-solving procedure for examining an information system and improving it?

Accepted Answer

The six-phase problem-solving procedure for examining an information system and improving it is called systems analysis and design. Prototyping, data flow diagramming, and modeling are techniques used within the systems analysis and design process. However, they are not the overall problem-solving procedure.

Question 9

The decision in which the systems analyst must decide whether to have a program custom-written or to purchase an existing software package is called the ________ decision.

Accepted Answer

The decision in which the systems analyst must decide whether to have a program custom-written or to purchase an existing software package is called the "make-or-buy" decision. In this case, the best choice would be C: to decide whether to purchase an existing software package or to develop it in-house. The choice depends on various factors such as cost, time, functionality, user requirements, and available resources. If the organization has the resources and expertise to develop custom software, then it may be more cost-effective and tailored to their specific needs. However, if time and budget are a constraint and there is an existing software package that meets most of their requirements, then purchasing may be the better option.

Question 10

If the performance of individual parts of a new system is examined using test (made-up or sample)data,what kind of testing is this?

Accepted Answer

Examining individual parts using test data is the definition of unit testing. This type of testing is done on the smallest unit of software design, such as a single function or module.

Question 11

Hardware,software,and files are converted to the new system and users are trained during the ________ phase of the SDLC.

Accepted Answer

During the systems implementation phase of the SDLC, hardware, software, and files are converted to the new system, and users are trained to use the new system. Other activities during this phase include system testing, data conversion, and user acceptance testing.

Question 12

In the SDLC,data is gathered and analyzed and a report is written during the _________ phase,systems analysis.

Accepted Answer

The systems analysis phase is typically considered the second phase in the Software Development Life Cycle (SDLC), following the initial planning or requirements phase. During this phase, data is gathered, analyzed, and a report is written to outline the findings and the requirements for the system.

Question 13

What is the actual step-by-step process followed during systems analysis and design?

Accepted Answer

The step-by-step process followed during systems analysis and design is known as the Systems Development Life Cycle (SDLC). It includes stages such as planning, analysis, design, implementation, and maintenance. This provides a structured approach for developing information systems, ensuring that they meet the needs of users and the organization they serve.

Question 14

The way data flows through a system is graphically shown by a ________.

Accepted Answer

A data flow diagram is a graphical representation of how data flows through a system, from input to processing to output. It helps designers and analysts to visualize the system's components and how they interact, making it a useful tool for planning and identifying potential problems. Models, prototypes, and detail designs are also important parts of the design process, but they do not specifically show the flow of data through the system.

Question 15

In step 1 of the SDLC,________,the first analysis is conducted,alternative solutions are proposed,costs and benefits are described,and a preliminary plan with recommendations is submitted.

Accepted Answer

The correct step in the SDLC is the Preliminary Investigation phase. This is where initial analysis is conducted, alternative solutions are proposed, costs and benefits are described, and a preliminary plan with recommendations is submitted.

Question 16

Programs that automate means of designing and changing systems during several phases are ________.

Accepted Answer

Programs that automate means of designing and changing systems during several phases are known as Computer-Aided Software Engineering (CASE) tools. Prototypes are early, preliminary models or working versions of a planned product or system. Trial products are products released for a limited time to get feedback from users. Archetypes are general, universally recognized symbol or character type in storytelling. Therefore, the best choice is B.

Question 17

A limited working system,or part of one,developed to test design concepts is a ________.

Accepted Answer

A prototype is a limited working system or part of one developed to test design concepts. A CASE (Computer-Aided Software Engineering) is a set of tools used to assist in software development. Example and sample do not specifically relate to the concept of a limited working system developed for testing.

Question 18

The systems analyst acquires the software,hardware,and then tests the system during the ________ phase of the SDLC.

Accepted Answer

The systems development phase of the Systems Development Life Cycle (SDLC) involves acquiring the necessary software and hardware and testing the system to ensure it meets the required specifications and functions correctly.

Question 19

In Phase 5 of the SDLC,if the old and new systems are operated side by side until the new system has proven itself,this is what type of system conversion plan?

Accepted Answer

Parallel implementation involves operating the old and new systems simultaneously until the new system has proven its effectiveness. This approach allows for thorough testing and minimal disruption to operations.

Question 20
