ISTQB Exam CTAL-TTA Topic 4 Question 4 Discussion

Actual exam question for ISTQB's CTAL-TTA exam

Question #: 4
Topic #: 4

You are asked to provide a practical and pragmatic testing solution for a commercial system where the main user interface is via the Internet. It is critical that the company's existing good name and market profile are not damaged in any way. Time to market is not a critical issue when appropriate testing solutions are identified to mitigate business risks.

A product risk assessment has revealed the following product risk:

* Abnormal application termination due to connection failure of the main interface.

Which of the following is the appropriate test type to address this risk?

APerformance efficiency testing

BPortability testing

CReliability testing

DOperability testing

Show Suggested Answer

Suggested Answer: C

Reliability testing is the process of checking whether the software consistently performs according to its specifications. For a commercial system with a critical internet-based user interface, ensuring that the application can handle connection failures without abnormal terminations is essential. Reliability testing would include testing the system's ability to recover from failures and continue operating, which directly addresses the risk identified.

I think reliability testing is the way to go here. We need to ensure the system can handle connection failures and not just crash.

I practiced a similar question where I had to find the labor time for multiple units. I think we need to use the exponent formula with the learning curve.

The key is "after paying debt and taxes." That narrows it down to either Net income or Operating profit. I think Net income is the better choice since it's the final earnings number available to equity owners.

This looks tricky, but I think I can figure it out. Spearman's rank correlation is all about comparing two sets of rankings, right? So I'll need to rank the hotels on both measures, then do some calculations to find the final coefficient. I may need to refer to my formula sheet, but I'm confident I can work through this.

Hmm, I'm a bit unsure about the STRIP_OUTER_ARRAY option. I'll need to double-check the documentation on that one.

I remember studying brittle failures, but I'm not entirely sure if branched cracking is the right answer. It sounds familiar though.

I see your point, Horace. Performance efficiency testing could also be valuable in this scenario to test the system's response time and resource usage during connection failures.
