WGU C706 Secure Software Design - Test prep questions with Correct Answers

Which statement is true of a software development life cycle? A Workload testing should be performed while designing the functional requirements. B Parallel testing verifies whether more than one system is available for redundancy. C A software programmer should be the only person to develop the software, test it, and submit it to production D Unit testing should be performed by the developer and the quality assurance team. Correct Answer Answer D is correct. Unit testing should be performed by the developer and by the quality assurance team. Unit testing refers to the debugging performed by the programmer while coding instructions. The unit testing should check the validity of the data format, length, and values. After writing the instructions, the developer might run tools to detect errors. A software programmer should not be the only person to develop the software, test it, and submit it to production. Therefore, distinction of duties ensures checks by using formal procedures adopted by the quality assurance team. After the software program is submitted, it is again verified by the quality assurance team by using formal procedures and practices before sending it to the program library. Parallel testing is the process of feeding test data into two systems, which are the altered system and another alternative system, and comparing the results. The original system can serve as the alternative system. It is important to perform testing by using live workloads to observe the performance and the bottlenecks present in the actual production environment. Parallel testing ensures that the system fulfills the defined business requirements. It does not involve testing for redundancy. Designing the functional requirements is a part of the system design specifications stage and does not involve workload testing.
