ISTQB Exam ISTQB-CTFL Topic 1 Question 31 Discussion

Actual exam question for ISTQB's ISTQB-CTFL exam

Question #: 31
Topic #: 1

The following diagram displays the logical dependencies between requirements and the individual requirement priorities. For example, "R2->R3" means that R3 is dependent on R2. Priority is indicated by the number next to the letter ''P" i.e. P1 has a higher priority than P2.

Which one of the following options best describes the test execution sequence using both requirement dependency and priority

AR2. R1, R3. R4. R5, R6. R7, R8.

BR1, R2, R3, R4, R5, R6, R7, R8.

CR2, R4. R8, R5, R1, R6, R3, R7.

D. R2, R1,R3,R7,R6,R5,R4,R8.

Show Suggested Answer

Suggested Answer: D

The correct test execution sequence should consider both the dependencies between the requirements and their priorities. According to the diagram, the sequence begins with R2 (P1) as it is a prerequisite for R3 (P4). Then R1 (P3) can be tested. R3 follows as it depends on R2. Next, R7 (P4) should be tested before R6 (P3) and R5 (P2), as indicated by their dependencies. Finally, R4 (P1) and R8 (P1) can be tested. Therefore, the best sequence is R2, R1, R3, R7, R6, R5, R4, R8. Reference: ISTQB CTFL Syllabus V4.0, Section 5.1.5

Ah, the age-old dilemma of requirement dependencies and priorities. I'm feeling lucky, so I'll go with A. Who needs logic when you have a gut feeling, am I right? *winks*

Woah, this is a tricky one! I'm gonna have to go with D. It looks like it follows the dependencies and the priorities, but I might be missing something. Hope I don't get this one wrong!

Hmm, I'm not too sure about this one. The diagram is a bit confusing, but I'll go with B. It's the simplest option and covers all the requirements.

User3: I agree, B seems like the safest bet considering the dependencies and priorities shown in the diagram.

Yeah, B looks like the most straightforward sequence to follow based on the diagram.

I think B is the best choice too. It seems to cover all the requirements in a logical order.

I think the correct answer is C. The test execution sequence should follow the requirement dependencies, with higher priority requirements tested first. This makes the most sense based on the diagram.
