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

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.

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.

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.
