CTFL Certification ISTQB Foundation Level
EXAM 1 2025 QUESTIONS AND
ANSWERS
Question #1 (1pt) What is the test basis?
a. The point during software development when testing should start
b. The body of knowledge used for test analysis and design
c. The source to determine the actual results from a set of tests
d. The method used to systematically devise test conditions - ANS B is correct. Per the
glossary, the test basis is "a source to determine expected results to compare with the actual
result of the system under test". A is not correct because this is usually defined as the moment
of involvement for testing. C is not correct because this is the test oracle. D is not correct
because the test basis is not a method
Question #2 (1 pt)
When the tester verifies the test basis while designing tests early in the lifecycle, which
common test objective is being achieved?
a. Gaining confidence
b. Finding defects
c. Preventing defects
d. Providing information for decision making - ANS C is correct per the syllabus. The other
three are achieved primarily by doing dynamic testing. This is a bit tricky because you are very
likely to find defects while doing this analysis and this may lead to either gaining or destroying

, confidence and needing to supply information to the decision makers. However, the wording of
the question matches the wording in the syllabus that defines preventing defects.
Question #3 (1 pt)
When following the fundamental test process, when should the test control activity take place?
a. During the planning activities
b. During the implementation and execution activities
c. During the monitoring activities
d. During all the activities - ANS D is correct. Control occurs throughout the project to ensure
that it is staying on track based on the plan and to take any corrective steps that may be
necessary. The monitoring information is used to determine if control actions are needed.
Question #4 (1 pt)
Which of the following is a correct statement?
a. A developer makes a mistake which causes a defect that may be seen as a failure during
dynamic testing
b. A developer makes an error which results in a failure that may be seen as a fault when the
software is executed
c. A developer has introduced a failure which results in a defect that may be seen as a mistake
during dynamic testing
d. A developer makes a mistake which causes a bug that may be seen as a defect when the
software is executed - ANS A is correct. The developer makes a mistake/error which causes a
defect/fault/bug which may cause a failure when the code is dynamically tested or executed. B
is incorrect because fault and failure are reversed. C is incorrect because failure and mistake are
reversed. D is incorrect because it's a failure that's seen during execution, not the defect itself.
The failure is a symptom of the defect

Question #5 (1 pt)

, Which of the following is an example of debugging?
a. A tester finds a defect and reports it
b. A tester retests a fix from the developer and finds a regression
c. A developer finds and fixes a defect
d. A developer performs unit testing - ANS C is correct. Debugging is what the developer
does to identify the cause of the defect, analyze it and fix it. D may involve debugging, if the
developer finds a defect, but the act of unit testing is not the same as debugging.
Question #6 (1 pt)
Which of the following is a true statement about exhaustive testing?
a. It is a form of stress testing
b. It is not feasible except in the case of trivial software
c. It is commonly done with test automation
d. It is normally the responsibility of the developer during unit testing - ANS B is correct.
Exhaustive testing, all combinations of inputs and preconditions, is not feasible unless the
software is trivially simple.Otherwise it would take too long and might not even be possible
Question #7 (1 pt)
A new retail product was released to production by your company. Shortly after the release it
was apparent that there were numerous problems with the point of sale application. This
resulted in a number of customer complaints and negative postings on social media
encouraging people to take their business to your competitor. You have investigated the
problems and have discovered that the production point of sale equipment is a later model
than the model used in testing. The software functions correctly on the old version, but fails on
the later model.

Given this scenario, what is the root cause and what is the effect?
@COPYRIGHT BRAINBARTER 2025/2026
, a. The root cause is the old equipment and the effect is the new equipment
b. The root cause is the customer complaints and the effect is the social media postings
c. The root cause is conducting the testing on the wrong version of the equipment and the
effect is the custome - ANS C is correct. The root cause is that the testing, and maybe the
development, were conducted on the wrong version of the POS equipment. The effect of the
problem is the customer complaints and the social media postings.
Question #8 (1 pt)
If you need to provide a report showing test case execution coverage of the requirements, what
do you need to track?
a. Traceability between the test cases and the requirements
b. Coverage of the risk items by test case
c. Traceability between the requirements and the risk items
d. Coverage of the requirements by the test cases that have been designed - ANS A is
correct. In order to show the test execution coverage of the requirements you will need
traceability between the requirements and the test cases. As the test cases are executed this
traceability can be used to record tests executed against the requirements. B is not correct
because it's looking for requirements coverage, not risk coverage. C is not correct because it's
looking for test execution, not risk items. D is not correct because it's looking for test cases that
have been executed, not just designed.
Question #9 (1 pt)
Which of the following is most correct regarding the test level at which functional tests may be
executed? ,,
a. Unit and integration
b. Integration and system

c. System and acceptance
