IBPS SO 2018 Professional Knowledge Quiz for IT

IBPS SO IT Officer is amongst the most reputed jobs in the Banking Sector and many Aspirants work hard to get this job. The exam for this post consists of various subjects other than the common subjects in Bank exams. Here we are providing you with a quiz based on Information Technology which will cover Networking chapters of professional knowledge for IT Officer exam. Practice with the questions based on the most updated pattern.

Q1. Which level of testing is evaluating the software/system compatibly with the business requirements?

Integration testing

System testing

Acceptance testing

Unit Testing

Evaluation Testing

Solution:

Acceptance testing (or User Acceptance Testing), is conducted to determine whether the system is ready for release. During the Software development life cycle, requirements changes can sometimes be misinterpreted in a fashion that does not meet the intended needs of the users. During this final phase, the user will test the system to find out whether the application meets their business’ needs. Once this process has been completed and the software has passed, the program will then be delivered to production.

Q2. What is UML (Uniform Modeling Language)?

Designing technique

Testing technique

Maintenance technique

Delivery Technique

Debugging Technique

Solution:

UML is a common language for business analysts, software architects and developers used to describe, specify, design, and document existing or new business processes, structure and behavior of artifacts of software systems. UML can be applied to diverse application domains (e.g., banking, finance, internet, aerospace, healthcare, etc.) It can be used with all major object and component software development methods and for various implementation platforms (e.g., J2EE, .NET).

Q3. Which of the following software development model is also referred as Linear Sequential Model?

Spiral Model

Iterative Model

Waterfall Model

Incremental Model

V-Model

Solution:

In the waterfall model (also known as the classical life cycle model), the development of software proceeds linearly and sequentially from requirement analysis to design, coding, testing, integration, implementation, and maintenance. Thus, this model is also known as the linear sequential model.

Q4. Which is not a software life cycle model?

Waterfall model

Spiral model

Prototyping model

Capability maturity model

V-model

Solution:

Capability Maturity Model because CMM is not a software life cycle model. Instead, it is a strategy for improving the software process.

Q5. Acceptance tests are normally conducted by the:

developer

end users

test team

systems engineers

None of these

Solution:

Acceptance testing, a testing technique performed to determine whether or not the software system has met the requirement specifications. This is a type of testing done by users, customers, or other authorized entities to determine application/software needs and business processes.

Q6. What are the qualities of good software?

Reliability

Correctness

Efficiency

Portability

All of the above

Solution:

Quality of software is not just concern with what software does, it also includes the software’s behavior while it is executing and the structure and organization of the system programs and associated documentation. Quality of good software is- reliability, correctness, efficiency, portability, flexibility, maintainability etc.

Q7. If user participation is available, which model is to be chosen?

Waterfall

Iterative enhancement model

Spiral model

RAD model

V-model

Solution:

The RAD (Rapid Application Development) model is based on prototyping and iterative development with no specific planning involved. In RAD Model software give it to user for evolution and obtain feedback.

Q8. In which debugging technique, when an error has occurred, one needs to start tracing the program backward one step at a time evaluating the values of all variables until the cause of error is found?

Cause Elimination

Program Slicing

Backtracking

Brute Force Method

None of these

Solution:

In Backtracking method, beginning from the statement at which an error symptom has been observed, the source code is traced backwards until the error is discovered. Unfortunately, as the number of source lines to be traced back increases, the number of potential backward paths increases and may become unmanageably large thus limiting the use of this approach.

Q9. Which of the following maintenance strategies involves performing maintenance before problems occur to avoid breakdowns and disruptions?

Perfective Maintenance

Corrective Maintenance

Adaptive Maintenance

Preventive Maintenance

Breakdown Maintenance

Solution:

Preventive maintenance refers to regular, routine maintenance to help keep equipment up and running, preventing any unplanned downtime and expensive costs from unanticipated equipment failure. It requires careful planning and scheduling of maintenance on equipment before there is an actual problem as well as keeping accurate records of past inspections and servicing reports.

Q10. Which phase is not available in software life cycle?

Coding

Testing

Maintenance

Abstraction

None of the above

Solution:

Abstraction is not a software development life cycle phase.

Q11. Which of the following is testing is also known as clear box testing?

White box testing

Black box testing

Grey box testing

Behavioral testing

None of these

Solution:

White Box Testing (also known as Clear Box Testing, Glass Box Testing) is a software testing method in which the internal structure/ design/ implementation of the item being tested is known to the tester.

Q12. Alpha testing is done by:

Customer

Tester

Developer

All of the above

Only (a) and (b)

Solution:

Alpha testing takes place at the developer's site by the internal teams, before release to external customers. Alpha testing is one of the most common software testing strategy used in software development. It is specially used by product development organizations.

Q13. Which one is the most important feature of spiral model?

Quality management

Risk management

Performance management

Efficiency management

Cost management

Solution:

Spiral Model is a combination of a waterfall model and iterative model. Each phase in spiral model begins with a design goal and ends with the client reviewing the progress. Risk Management is the most important feature of spiral Model.

Q14. Which process is the examination and alteration of a system to reconstitute it in a new form?

Software reengineering

Software reverse engineering

Software forward engineering

Software testing

Software costing

Solution:

Software Reengineering is the examination and alteration of an existing subject system to reconstitute it in a new form. This process encompasses a combination of sub-processes such as reverse engineering, restructuring, redocumentation, forward engineering, and retargeting.

Q15. Regression testing in primarily related to which type of testing?

Functional testing

Data flow testing

Development testing

Maintenance testing

None of these

Solution:

Regression testing is a type of software testing which verifies that software which was previously developed and tested still performs the same way after it was changed or interfaced with other software. Changes may include software enhancements, patches, configuration changes, etc. Regression testing is related to maintenance testing.
