Solutions

S1. Ans.(c)

S2. Ans.(e)
Sol. Black Box Testing is a software testing method in which the internal structure/ design/ implementation of the item being tested is NOT known to the tester. White Box Testing is a software testing method in which the internal structure/ design/ implementation of the item being tested is known to the tester.

S3. Ans.(b)
Sol. The risks associated with technology might affect the product development.

S4. Ans.(c)
Sol. A software requirements specification (SRS) is a description of a software system to be developed, laying out functional and non-functional requirements, and may include a set of use cases that describe interactions the users will have with the software. (Source Wiki) Design Specification should not be part of SRS.

S5. Ans.(d)
Sol. Debugging is a systematic process of spotting and fixing the number of bugs, or defects, in a piece of software so that the software is behaving as expected. There are different types of debugging technique- Print debugging, Remote debugging, Communication based debugging, Memory-dump debugging (often referred to as core dump), Replay debugging, Logfile debugging.

S6. Ans.(a)
Sol. Data flow diagrams are used by information technology professionals and systems analysts to document and show users how data moves between different processes in a system.

S7. Ans.(b)
Sol. Back Tracking is a debugging technique, It is a quite popular approach of debugging which is used effectively in case of small applications. The process starts from the site where a particular symptom gets detected, from there on backward tracing is done across the entire source code till we are able to lay our hands on the site being the cause. Unfortunately, as the number of source lines increases, the number of potential backward paths may become unmanageably large.

S8. Ans.(d)
Sol. White box testing is a testing technique which evaluates the code and the internal structure of a program.

S9. Ans.(c)
Sol. The goal of the requirements analysis and specification phase is to clearly understand customer requirements and to systematically organize these requirements in a specification document.

S10. Ans.(d)
Sol. A software requirements specification (SRS) is a description of a software system to be developed. It lays out functional and non-functional requirements and may include a set of use cases that describe user interactions that the software must provide.
