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.

REST (Representational State Transfer)is a widely usedweb service protocolthat enablesclient-server communicationover HTTP. It is commonly used inmodern APIs and web applicationsfor performance testing.

Option A (SOAK)refers tosoak testing, which evaluates performance over an extended period.

Option C (HTTP)is atransport protocol, butRESTis the actual web service architecture built on HTTP.

Option D (RTE)isnot a web service protocolbut may refer toReal-Time Enterprise systems.

Aggregating test resultshelps stakeholders understand performance trendsbycombining data points from multiple test runs. This makes iteasier to draw conclusionsabout system behavior.

Option A is incorrectbecause aggregation may reduce detailed visibility, not increase it.

Option B is incorrectbecause aggregation does notexpedite testing itself.

Option D is incorrectbecause aggregated results do not indicatetest completion.
