ISTQB Exam CT-PT Topic 2 Question 12 Discussion

Actual exam question for ISTQB's CT-PT exam
Question #: 12
Topic #: 2
[All CT-PT Questions]

You have run a load test. When examining the metrics, you see that the virtual users experienced many timeouts and excessive wait times. The system throughput metrics exceeded expected results, even during peak times.

Based on your analysis, what conclusion should you draw?

Show Suggested Answer Hide Answer
Suggested Answer: B

If timeouts and excessive wait times occur, but throughput is high, this suggests that the system is unable to process requests fast enough. This points to slow processing speed due to CPU bottlenecks, memory limitations, or inefficient database queries.

Option A (Network infrastructure investigation) would be relevant if throughput was low or variable.

Option C (Impatient virtual users) is irrelevant; virtual users follow scripted behaviors.

Option D (New test data) does not address the core issue.

This seems like a tricky one. I'll need to think through the metrics carefully to figure out the root cause.

But what about the processing speed? Could that be the issue?

Virtual users being impatient? Hah, good one! They're machines, they don't get bored like us humans. I'm going with network issues on this one.

New test data? Come on, the metrics are clear as day. Time to take a close look at that network infrastructure, my friend.

Processing speed too slow? Nah, the throughput metrics are through the roof! Definitely something up with the network here.

I agree with Katie, it could be causing the timeouts.

Hmm, with those timeouts and wait times, I'd say the network infrastructure is the culprit. Gotta fix that bottleneck!
