ISTQB-CTFL Exam - 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

Wait, are we sure R4 is after R5? That seems weird.

R2 is definitely a prerequisite for R3.

I believe the correct sequence should start with R2, but I’m not confident about the rest of the order.

I'm a bit confused about the order; I feel like R4 might need to come after R2, but I can't recall the exact dependencies.

I remember a similar question where we had to consider both priority and dependencies, and I think R2 should come before R3.

I think we need to prioritize R1 first since it has the highest priority, but I'm not sure about the dependencies.

This is a good example of why understanding requirement relationships is so important for test planning. I feel confident I can work through this step-by-step.

I'm a bit unsure about this one. The dependencies seem straightforward, but balancing that with the priorities is making it tricky. I'll need to double-check my work.

Okay, I think I've got it! The key is to start with the highest priority requirements that don't have any dependencies, then work my way down.

Hmm, the diagram shows some clear dependencies, but the priorities are a bit confusing. I'll need to map those out to figure out the optimal order.

This looks like a tricky one! I'll need to carefully consider the requirement dependencies and priorities to determine the best test execution sequence.

I remember discussing how on-premises workloads might be better suited for low latency needs, so maybe option D is the answer.

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*

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.
