Assume you have some data related to confirmation testing during system testing of a past project.In that project 240 bug reports have been opened once, 80 were opened twice, 10 were opened three timesand no bug reports have been opened more than three times.You estimate that a bug report, which has failed its confirmation test, costs, on average, 3 person-hours.Which of the following statements correctly describe the value of these confirmatory testing activities basedon cost of quality?

Which of the following information would you expect to be the most useful to perform a defect clustering analysis?

Assume you are working on a CAS (Conditional Access System) for Pay-TV that allows the access,selection and transfer of services and media to authorized users. Authorized users can choose theirservices through different channels: Web Customer Portal, IVR (Interactive Voice Response), Call Centreand SMS. The system uses a Smart Card to receive and decrypt the broadcasted encrypted control wordswhich allow decrypting pay-per-view TV. Every authorized user must have a Smart Card and a Set-Top Boxto view the contents.The following is an excerpt from the product risk analysis document:Both likelihood and impact have been rated on the following scale: (1 – Very low, 2 – Low, 3 – Medium, 4 –High, 5 – Very High).The required test environment and code have been delivered. All test cases for each identified product riskitem have been written and are ready to be executed. The Database used to contain the Smart Cards isempty and so only new Smart Cards can be used during test execution.A Smart Card can only be activated if it has been previously pre-activated. This means the post-conditionsfor the execution of the test cases to test the pre-activation of the Smart Card are the pre-conditions foractivation of the Smart Card.Which of the following statements represents the most effective contribution of the stakeholders to thecompletion of the failure mode analysis table?

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 SoftwareConfiguration 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 standardThese 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 coveragemeasurements, in order to meet the structural coverage criteria prescribed by the DO-178B standard. Thistool 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 toolthat is able to provide different types of code coverage. This tool meets perfectly your technical needs interms of the programming language and the specific hardware platform (it supports also the specific Ccompiler).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 averification tool under the DO-178B.Which of the following are the three main concerns related to that open-source tool selection?

In the next two months some new features will be constantly added to new releases of a project you areworking on as Test Manager.You have identified as one of the main project risks, that the requirements specification will still beincomplete when your team starts the test design and implementation phase.Some requirements will most likely be completed too late to allow a proper test preparation.You and your test team have already worked on several similar past projects in the same organization.Which one of the following options would you expect to be the most effective at mitigating this risk?
