Master iSQI CTAL-TM_Syll2012 Exam with Reliable Practice Questions

You are the Test Manager of a new project aimed at developing a software system that must be certified at level B of the DO-178B standard. The project will follow a V-Model software development life cycle and it will have four formal levels of testing: component, integration, system and acceptance testing.

You must produce the test plan documentation for this project by providing an adequate coordination across the four levels of testing in order to assure audit ability.

Which of the following answers would you expect to best describe how to organize the test plan?

Based on the historical data of 5 past and similar projects, you have calculated these average numbers of defects detected in system testing.

- For each 10000 LOC (lines of code), 200 defects

- For each person-month of development team effort, 49 defects

You want to use this information to perform estimation for a new project.

The project manager tells you that he/she has estimated 20000 new LOC for this new project.

Four developers work for four months on this project before system testing.

During system testing, 797 defects are discovered.

Assume that the system test of this new project is using the same amount of work as spent in the past projects.

Based on this information only, which of the following statement is certainly true about this project? K3 3 credits

You are estimating the effort for the integration testing activities of a new project. Consider the following factors, which can affect that estimation:

. Availability of re-usable test systems and documentation from previous, similar projects

2. Unexpected timing of components arrival

3. Stability of the integration test team (no turnover)

4. Many and geographically distributed sub-teams

Which of the following statements is true?

K2 1 credit

The following chart plots the cumulative number of defects opened against the cumulative number of defects closed during system testing of a software product.

Which of the following statements is true? K2 1 credit

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 opensource 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?
