ISTQB Exam CTAL-TTA Topic 5 Question 17 Discussion

Actual exam question for ISTQB's CTAL-TTA exam

Question #: 17
Topic #: 5

Consider the following control flow graph:

The control flow represents a software component of a car navigation system. Within the project the maximum cyclomatic complexity to be allowed is set at 5.

Which of the following statements is correct?

ANo defect needs to be reported since the cyclomatic complexity of the component is calculated at 3.

BNo defect needs to be reported since the cyclomatic complexity of the component is calculated at 4

CNo defect needs to be reported since the cyclomatic complexity of the component is calculated at 5.

DA defect needs to be reported since the cyclomatic complexity of the component is calculated at 6.

Show Suggested Answer

Suggested Answer: C

Static analysis is the best technique for identifying the root causes of issues in a legacy system where small functional enhancements take disproportionately long to implement. This technique involves examining the code without executing it to detect potential vulnerabilities, coding errors, and complexities. Static analysis can highlight problematic code segments and inefficient coding practices that may contribute to the increased time required for implementing changes, thereby assisting in addressing these systemic issues efficiently.

Okay, let me get this straight - the component is too complex, but they're saying it's not a defect? I think the car navigation system just wants to take a few wrong turns, that's all. D is the right choice.

Yeah, the cyclomatic complexity is over the limit, so a defect should be reported.

But the maximum allowed cyclomatic complexity is 5, so D seems to be the right choice.

Haha, who's the genius that thought a complexity of 5 was acceptable when the limit is 5? Way to push the boundaries there! Definitely going with D.

Exactly, it's important to stick to the limits set for a reason.

Yeah, it's like they were asking for a defect to be reported.

I agree, setting the limit at 5 and then having a complexity of 6 is definitely a mistake.

Hmm, I'm not sure why anyone would think this is not a defect. If the limit is 5 and the component's complexity is 6, that's just math, right? D is the only logical answer.

Wait, so the maximum allowed cyclomatic complexity is 5, but the component's complexity is 6? Looks like a clear defect to me. Option D is the way to go here.
