ISTQB Exam CT-PT Topic 3 Question 5 Discussion

Actual exam question for ISTQB's CT-PT exam

Question #: 5
Topic #: 3

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?

ANetwork infrastructure should be investigated.

BProcessing speed is too slow.

CVirtual users are exhibiting impatient behavior.

DNew test data is needed.

Show Suggested 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.

Definitely network infrastructure. Those timeouts are a dead giveaway. I've seen this happen before when the network can't keep up with the load.
