CTAL-TM_UK Question #30: Real Exam Question with Answer & Explanation

Assume you are the Test Manager in charge of independent testing for avionics applications. You are in charge of testing for a project to implement three different CSCI (Computer Software Configuration Item): - a BOOT-X CSCI that must be certified at level B of the DO-178B standard - a DIAG-X CSCI that must be certified at level C of the DO-178B standard - a DRIV-X CSCI that must be certified at level A of the DO-178B standard These are three different software modules written in C language to run on a specific hardware platform. You have been asked to select a single code coverage tool to perform the mandatory code coverage measurements, in order to meet the structural coverage criteria prescribed by the DO- 178B standard. This tool must be qualified as a verification tool under DO-178B. Since there are significant budget constraints to purchase this tool, you are evaluating an open- source tool that is able to provide different types of code coverage. This tool meets perfectly your technical needs in terms of the programming language and the specific hardware platform (it supports also the specific C-compiler). The source code of the tool is available. Your team could easily customize the tool to meet the project needs. This tool is not qualified as a verification tool under the DO-178B. Which of the following are the three main concerns related to that open-source tool selection?
