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.

Aload generatoris responsible forsimulating virtual usersand applyingworkloads to a systemas defined by an operational profile. This allows testers to analyze how the system behaves under different load conditions.

Option A (Background load)is incorrect becauseload generators create simulated user interactions, not just background noise.

Option C (Record and analyze behavior)is the role ofmonitoring tools, not a load generator.

Option D (Support root cause analysis)is incorrect becauseroot cause analysis is done after the load test, using monitoring tools.

Resource allocation happens during the test planning phase, wherehardware, tools, and personnelare assigned to the project. This ensures that performance tests areadequately supported.

Option B (Test execution)is when resources are actually used, not allocated.

Option C (Test evaluation)happensafter executionto analyze results.

Option D (Test completion)focuses on documentation and reporting.
