Equivalence partitioning and boundary value analysis questions showed up as short scenarios where you pick the smallest set of cases that still cover all relevant conditions. Focus on turning requirements into partitions and explicitly testing boundaries, I passed the exam this way and thanks Pass4Success for a good collection of exam questions that sped up my prep.

Honestly, the trickiest part for me was differentiating when to apply boundary value analysis versus equivalence partitioning on multiple input fields. The scenario questions made me overthink, but sketching partitions and counting test cases on scrap paper helped.

Free ISTQB ISTQB-CTFL Exam Actual Questions

Note: Premium Questions for ISTQB-CTFL were last updated On May. 08, 2026 (see below)

Question #1

The following rules determine the annual bonus to be paid to a salesman of a company based on the total annual amount of the sales made (referred to as TAS).

If the TAS is between 50k and 80k, the bonus is 10%. If the TAS exceeds 80k by a value not greater than 40k, the bonus is 15%. Finally, if the TAS

exceeds the maximum threshold which entitles to a 15% bonus, the bonus is 22%.

Consider applying equivalence partitioning to the TAS (Note: 1k = 1000 euros).

Which one of the following answers contain only test cases that belong to the same equivalence partition?

Reveal Solution Hide Solution
Correct Answer: A

This answer is correct because equivalence partitioning is a test design technique that divides the input domain of a system or component into partitions of equivalent data, such that each partition is expected to produce the same output or behavior. Equivalence partitioning aims to reduce the number of test cases by selecting one representative value from each partition. In this case, the input domain of the TAS can be divided into four partitions based on the bonus rules: less than 50k, between 50k and 80k, between 80k and 120k, and more than 120k. The test cases in the answer belong to the same partition, which is between 80k and 120k, and they are expected to produce the same output, which is a bonus of 15%.Reference: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level Syllabus v4.0, Section 2.3.2.1


Question #2

Which of the following is a possible reason for introducing a defect in software code?

Reveal Solution Hide Solution
Correct Answer: A

The ISTQB CTFL syllabus identifies several causes for defects in software. One prominent reason, as highlighted in the curriculum, is the pressure and rush to meet tight deadlines, which can lead to insufficiently reviewed or tested code being moved into further stages of testing or production. This scenario describes rushing to meet a deadline as a potential cause for defects because it may compromise the thoroughness of code development and testing. Reference: ISTQB Certified Tester Foundation Level Syllabus v4.0, Section 1.4.1 'Why is Testing Necessary?'.


Question #3

Which ONE of the following is a characteristic of exploratory testing?

Reveal Solution Hide Solution
Correct Answer: A

Question #4

Which ONE of the following tools would be MOST SUITABLE for facilitating the creation of test cases, test data, and test procedures?

Reveal Solution Hide Solution
Correct Answer: A

Comprehensive and Detailed In-Depth Explanation:

The correct tool for creating test cases, test data, and test procedures is a test design and implementation tool (A).

(B) is incorrect as static testing tools focus on code analysis, not test case creation.

(C) is incorrect because DevOps tools manage automation pipelines, not test design.

(D) is incorrect because test execution tools focus on running tests rather than designing them.

Test design tools help optimize test coverage, reduce redundancy, and improve efficiency.


Question #5

Which of the following statements correctly describes error guessing?
