Question 1

Which of the following answers describes a factor that may reduce the effort spent when using distributed test teams without negatively affecting system quality?

Options :

A : Difficulties in communication between the distributed test teams due to time zone differences

B : With several distributed test teams, every team assumes that some test conditions are covered by other teams but actually no one covers them

C : With several distributed test teams, two or more teams assume some test conditions are covered by their team and their team alone. But all of the teams actually cover them

D : With several distributed test teams, all of the distributed test teams use a single unified test dashboard

Answer: D

Question 2

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?

Options :

A : 300 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of internal failure

B : 340 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of external failure

C : 340 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of internal failure

D : 300 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of detection

Answer: A

Question 3

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?

Options :

A : Don’t prepare any test and just run the regression test suite to check that the new features don’t introduce regression

B : Make reasonable assumptions about the missing details and design lightweight tests that can be easily updated during test execution

C : Don’t design any test until the test execution starts, then communicate that test execution is blocked due to incomplete requirements

D : Even if there are only few details missing, escalate the risk to the project manager without preparing any tests

Answer: B

Question 4

Which of the following answers describes a factor that may reduce the effort spent when using distributed test teams without negatively affecting system quality?

Options :

A : Difficulties in communication between the distributed test teams due to time zone differences

B : With several distributed test teams, every team assumes that some test conditions are covered by other teams but actually no one covers them

C : With several distributed test teams, two or more teams assume some test conditions are covered by their team and their team alone. But all of the teams actually cover them

D : With several distributed test teams, all of the distributed test teams use a single unified test dashboard

Answer: D

Question 5

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?

Options :

A : Does the tool support all the types of code coverage required from the three levels A, B, C of the DO178B standard?

B : Does the tool have a good general usability?

C : What are the costs to qualify the tool as a verification tool under the DO-178B?

D : Is the installation procedure of the tool easy?

E : Does the tool require a system with more than 4GB of RAM memory?

F : Is the licensing scheme of the tool compatible with the confidentiality needs of the avionics company?
