Question 1

Which of the following is a disadvantage of parallel implementation?
A) The process is unable to provide the same result that is produced by the existing system.
B) The process is expensive in nature and is usually in place for only a short period.
C) The process switches off the old system when two new processes are running.
D) The process can run only old systems as it does not have the set-up to operate on new systems.

Accepted Answer

Parallel implementation can be expensive due to the need for additional hardware and software, and it may only be required for a short period of time until the new system is fully implemented. A, C, and D are incorrect because parallel implementation is designed to provide the same or better results than the existing system, does not necessarily switch off the old system, and is not limited to operating only on old systems.

Question 2

Independent testers are critical in testing information systems because ________.
A) programmers are inept at testing their own code
B) end-users prefer a third-party feedback on the system
C) systems are utilized by end-users before they go live
D) government regulations require a third-party feedback before a system is approved

Accepted Answer

The answer of Independent testers are critical in testing information...

Question 3

Which of the following will take place in a parallel implementation?
A) launching the new system while the old one is still running
B) launching two new systems at the same time
C) switching off the old system when new processes are running
D) launching modules of the new system in phases rather than all at once

Accepted Answer

In a parallel implementation, the new system is launched while the old one is still running to ensure that the new system works correctly before fully transitioning.

Question 4

The ________ phase of the waterfall method involves nailing down the requirements, at which point the developers estimate the time and resources needed to complete the project.
A) analysis
B) implementation
C) development
D) testing

Accepted Answer

The analysis phase of the waterfall method involves gathering and defining the requirements of the project. Once the requirements are clearly defined, developers can estimate the time and resources needed to complete the project. Therefore, the best choice is A) analysis.

Question 5

The ________ refers to a process the organizations put into place to manage bug fixes and change requests. In this process, IT staff help clarify the revision and development requests and estimate the resources required to accomplish them.
A) conformity assessment process
B) calibration process
C) change control process
D) requirement analysis process

Accepted Answer

The change control process is specifically designed to manage bug fixes and change requests. It involves IT staff clarifying the revision and development requests and estimating the resources required to accomplish them. The other options (A, B, and D) are not as relevant to this process.

Question 6

Which of the following do all types of information system tests mimic?
A) problems the IT staff will face while developing the system
B) events the system will handle when it goes live
C) challenges the advertisers will face during online promotions
D) breakthrough solutions that the developers will create

Accepted Answer

All types of information system tests aim to mimic the events the system will handle when it goes live, such as user interactions, data inputs, and output results. It is important to test the system thoroughly to ensure it can handle all expected scenarios and avoid any potential issues or failures during deployment.

Question 7

Which of the following best describes legacy systems?
A) new systems which are unable to replace old systems
B) new systems which are replicas of old regal systems
C) old systems which are built on aging or obsolete architectures
D) old systems that are no longer in use

Accepted Answer

Legacy systems are old systems which are built on aging or obsolete architectures. They may still be in use, but are typically difficult and costly to maintain or update.

Question 8

Which of the following kinds of testing is conducted to assess how well the system performs under peak loads?
A) stress testing
B) parallel testing
C) unit testing
D) system testing

Accepted Answer

Stress testing is designed to determine the limits of a system's performance capacity under a high workload. It helps to identify bottlenecks, determine system capacity, and evaluate system behavior under extreme conditions. Parallel testing involves the simultaneous testing of two or more versions of a software application, while unit testing involves testing individual components or units of source code. System testing is a comprehensive testing approach that tests the entire system as a whole. None of the other options are specifically designed to test system performance under high loads.

Question 9

Which of the following is involved in integration testing?
A) checking the functionality of small modules of code during the development phase
B) conducting tests by IT staff to assess how well the system performs under peak loads
C) performing final testing by programmers to determine whether the project is complete as specified
D) testing the new system's interfaces with other software components it links to

Accepted Answer

Integration testing involves testing the new system's interfaces with other software components it links to. Options A, B, and C refer to other types of testing such as unit testing, load testing, and system testing respectively.

Question 10

Which of the following occurs during phased implementation?
A) focusing on different departmental groups at a time
B) launching the new system while the old one is still running
C) focusing on launching modules in steps rather than all at once
D) launching all the modules of the new one on a single go-live date

Accepted Answer

Phased implementation involves launching modules in steps, focusing on specific groups or departments at a time, instead of launching all the modules at once, in order to minimize disruption and allow for easier troubleshooting and support.

Question 11

A major advantage of the ________ implementation is that people whose roles span modules do not have to switch back and forth between old and new modules.
A) phased
B) direct
C) parallel
D) pilot

Accepted Answer

The direct implementation approach involves switching from the old system to the new system all at once, which means users do not have to switch between old and new modules.

Question 12

Which of the following kinds of testing involves using the same input where developers compare the new system's output to the output generated by the system it is replacing?
A) stress testing
B) parallel testing
C) unit testing
D) acceptance testing

Accepted Answer

Parallel testing involves using the same input to compare the output of the new system to the output of the system it is replacing. Stress testing involves detecting how well a system can handle high levels of traffic or activity. Unit testing involves testing each individual component of the system, and acceptance testing involves verifying that the system meets the requirements of the stakeholders.

Question 13

A disadvantage of ________ is that the new system's modules may be tightly integrated, so implementing one without the others may create some confusion and require temporary interfaces to the old systems.
A) phased implementation
B) direct implementation
C) parallel implementation
D) hot standby implementation

Accepted Answer

Phased implementation involves introducing new modules one at a time, which can lead to confusion and temporary interfaces when implementing new modules without the others. Direct implementation involves switching immediately to the new system, parallel implementation involves running both the old and new systems simultaneously, and hot standby implementation involves maintaining a backup system in case of failure. None of these options would have the same disadvantage as phased implementation.

Question 14

A ________ implementation launches the new system while the old one is still running and employees either do their jobs twice or two separate teams handle the same processes.
A) phased
B) direct
C) parallel
D) pilot

Accepted Answer

A parallel implementation involves running both the old and new systems simultaneously. This allows for a direct comparison of the two systems and reduces the risk of failure or disruption to operations. However, it can result in duplicate work or the need for additional staffing to ensure both systems are being operated effectively.

Question 15

Which of the following is a drawback of the waterfall method?
A) It is unable to adapt to changes of the business landscape.
B) Its activities occur at the same time which makes it hard to monitor them.
C) It estimates deliveries based on the time and requirements available.
D) Its SDLC tasks occur in non-sequential manner.

Accepted Answer

The waterfall method is a linear sequential approach where each phase must be completed before the next phase can begin. This makes it difficult to adapt to changes in the business landscape since any changes will require going back and redoing previous phases.

Question 16

A ________ implementation switches off the old system and launches all the modules of the new one on a single, very hectic go-live date, sometimes called the "big bang."
A) phased
B) direct
C) parallel
D) standby

Accepted Answer

The description given matches the direct implementation where the old system is replaced with the new one on a single go-live date, also known as "big bang." Phased implementation involves a gradual rollout of new modules or processes in stages, while parallel implementation runs both old and new systems simultaneously for comparison purposes. Standby implementation involves having a backup or redundant system ready to take over in case of a failure.

Question 17

Which of the following is an advantage of parallel implementation?
A) The process is inexpensive and thus can be undertaken over a long period of time.
B) The process makes both systems process the same case, and if the new one operates well, the output is the same.
C) The existing process is automatically switched off when new processes are running, which limits redundancy.
D) The implementation makes each system process distinctly different cases.

Accepted Answer

Parallel implementation involves running both the existing and the new system simultaneously, processing the same cases. This allows for direct comparison of the output from both systems, which helps ensure that the new system operates well and produces the same output as the existing system. This is an advantage because it reduces the risk of errors and discrepancies in the output. The other options (A, C, and D) are not characteristics of parallel implementation or are incorrect.

Question 18

The ________ involves the sequential occurring of systems development lifecycle tasks, with one activity starting only after the previous one has been completed.
A) iterative method
B) agile method
C) waterfall method
D) Gauss-Seidel method

Accepted Answer

The description provided matches the classic waterfall method, where each stage in the development cycle must be completed before moving on to the next one. The other options, iterative and agile methods, involve cycles of development where tasks may overlap or be revisited multiple times before completion. The Gauss-Seidel method refers to a numerical analysis technique and is not related to software development.

Question 19

________ is the only strategy for small systems, but the risk of switching back and forth between old and new modules can be high for large-scale implementations of complex software involving thousands of employees.
A) Phased implementation
B) Direct implementation
C) Pilot implementation
D) Parallel implementation

Accepted Answer

Direct implementation involves switching from the old system to the new one at once, which can be risky for large-scale systems due to potential issues and lack of fallback options.

Question 20

Escapade, a travel house in Sydney, uses an implementation process which is expensive and used for only a short period of time. Which of the following is the company using if it launches the new system while the old one is still running and employees do their jobs twice, once on each system?
A) parallel implementation
B) phased implementation
C) direct implementation
D) pilot implementation

Accepted Answer

The scenario described is that of parallel implementation, where both the old and new systems run simultaneously and employees perform their job on each system in order to ensure a smooth transition without disrupting operations.
