ISTQB CTAL-TAv4.0 Exam Practice Questions and Answers

Question 6 of 42

Which of the following shows the test analyst’s contribution to interoperability testing?

Designing test cases based on risk analysis for installation and uninstallation procedures

Verifying that the system under test can share its target environment with other products

Verifying that all planned functionality has actually been implemented

Finding defects in communication protocols that describe data exchange

Question 7 of 42

You are testing an image recognition system. The system is based on a deep neural network. As input, the system receives an image (1000x1000 pixels) of a geometric figure - a triangle, square, or circle. The figure is one color and is depicted on a solid background of another color. The figure can be of any size and placed anywhere on the picture. The system classifies the figure on output as a triangle, square, or circle. If the system receives an image that does not meet the above requirements, it responds with “unrecognized shape.”
You want to test the correctness of this system using metamorphic testing.
Which of the following is NOT a valid metamorphic relation for this scenario?

Changing the position of the figure (but so that it is still visible in its entirety) does not change the system’s answer

Rotating the image 90 degrees to the right or left does not change the system’s response

Changing the figure's color does not change the system’s response

Scaling down the figure does not change the system’s response

Question 8 of 42

Which of the following BEST shows a test analyst’s contribution to flexibility testing?

Verify that the program does not leave undeleted files after uninstallation

Verify that the program can handle workload variability

Verify that the system is compatible with the products with which it interacts

Verify that a specific system component can be replaced seamlessly by another

Question 9 of 42

Which type of tools provide traceability of test cases to test basis elements?

Test management tools

Defect management tools

Test data management tools

Version control tools

Question 10 of 42

Which option BEST describes a test analyst’s involvement in different software development lifecycles?

In sequential models, the test analyst focuses primarily on functional testing. In iterative models, the test analyst focuses primarily on non-functional testing.

In sequential and incremental models, the test analyst focuses on automating regression testing. In iterative models, the test analyst focuses on manual testing.

In sequential models, the test analyst executes tests in the late phases of the software lifecycle. In incremental models, the test analyst executes tests in each increment.

In sequential models, the test analyst mainly uses experience-based test techniques. In iterative models, the test analyst mainly uses black-box test techniques.
