CT-PT Exam Dumps : ISTQB Certified Tester - Performance Testing

To ensure anaccurate operational profile, it is crucial tovalidate and adjust it with key stakeholders before executing tests. This step ensures that the workloadrealistically represents actual user behavior.

Option A (Executing the test first and adjusting later)is incorrect becauseadjustments should be made before executionto avoid misleading results.

Option C (Aggregating profiles into a single generic profile)removesimportant distinctions between different user types, reducing test accuracy.

Option D (Creating separate profiles and using equal proportions)does not match the actualpower purchaserbehavior, which requires arealistic representation of their higher-volume transactions.

When system resources areoversaturated(e.g., CPU, RAM, or network bandwidth),responsetimes will degradebecause the systemstruggles to process requests efficiently. This is akey performance bottleneck indicator.

Option A is incorrectbecause response times do not improve under heavy load; they typically worsen.

Option C is incorrectbecauseerror logging may actually increaserather than decrease under stress.

Option D is incorrectbecause database size is independent of system saturation unless records are actively purged.

Performance monitoring toolscollectreal-time and historicalperformance data, particularly fromserver logs, application metrics, and infrastructure monitoring. This allows testers to analyze performance trends efficiently.

Option A is incorrectbecause monitoring toolsdo not preventmalicious behavior but may detect it.

Option C is incorrectsinceidentifying multi-threading issuesis typically done throughprofiling toolsrather than performance monitors.

Option D is incorrectasDoS attack detectionfalls undersecurity testing.
