Free and Premium ISTQB CT-PT Dumps Questions Answers

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.

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.

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.

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.

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.

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.

Astatic performance testis anon-execution-based reviewthat analyzes system architecture, network configurations, and other elements thataffect system performance before execution.

Option A (Usability test)is not a static performance test but rather a functional or UX evaluation.

Option B (Evaluation of testers' skills)is unrelated to performance testing.

Option D (Formal signature approval)is an administrative task and not a static test.

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.

During performance testing, it is crucial to definefailure handling proceduresto ensure thatfailures do not introduce additional errorsinto the test execution process. This helpsmaintain test accuracyandavoid misleading results.

Option A (Meeting stakeholder expectations)is important but not the primary reason for defining failure handling.

Option C (Capturing all defects)is ageneral testing principle, not specific to failure handling in performance tests.

Option D (Minimizing distractions)is not a valid reason for defining failure handling.

Aload management consoleis a tool that helps testersanalyze and visualize test results, providingperformance reports, graphs, and insights. This aids in understandingbottlenecks, response times, and throughput trends.

Option A (Simulating user behavior)is incorrect;load generatorshandle simulation.

Option B (Senior management monitoring)is not the primary role of atest console.

Option D (Emulating virtual users)is incorrect; that is the job ofload injectors.

Spike testingis a type of performance testing that evaluates how a systemresponds to sudden, extreme increases or decreases in load. It is designed to simulateunexpected surges in user activity or workload, such as flash sales, viral events, or cyberattacks.

Option A (Gradual load increase testing)describesload testing, not spike testing.

Option B (Handling expected peak load)describesstress testing, which pushes the system to or beyond its limits but does not focus on sudden changes.

Option C (Meeting future efficiency requirements)relates tocapacity planningrather than spike testing.

Spike testing helps toidentify system bottlenecks, resource allocation issues, and performance degradationwhen traffic surges unexpectedly.
