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

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.

One of thebest practices in performance test scriptingis tovalidate that correct data is recorded in the databaseafter execution. This ensures thatperformance issues do not impact data integrity.

Option A (Increasing the number of scripts)may providemore coverage but does not verify accuracy.

Option C (Adding transaction timers)is useful for performance monitoring but does not ensurecorrect data entry.

Option D (Holding the development team accountable)is amanagement responsibility, not a scripting best practice.
