Pass the ISTQB Software Testing & Quality CT-PT Questions and answers with ValidTests

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.

Forbatch processing performance metrics, the two most important factors are:

Throughput– Measures the number of transactions processed over time.

Wait times– Evaluates delays in processing batches.

Option B (Number of records deleted)is irrelevant unless batch processing specifically involves deletions.

Option C (Network latency percentage)applies toreal-time transaction processing, not batch jobs.

Option D (Concurrent virtual users)applies more toload testingrather than batch performance.

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.

Crowd-based load generationinvolves using distributed users (e.g., cloud-based testers or real users). The mainchallengeis thatthe load generation can be difficult to reproduce consistentlydue to variations innetwork conditions, device types, and user behavior.

Option B is incorrectbecause load generation methods should adapt to system changes.

Option C is incorrectsince mainframe applications typically do not rely on crowd-based testing.

Option D is incorrectbecause crowd-sourced load testing is generallyless precisethan scripted load 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.

One of the keyperformance risks in mainframe architecturesisslow hard disk speed, which canimpact transaction processing, batch jobs, and database access times.

Option A (Inconsistent loads via APIs)is more relevant todistributed or cloud architecturesrather than mainframes.

Option C (Misconfigured host machine)is aconfiguration issue, not a typical performance risk.

Option D (Lack of RAM)is less common in mainframes, which typically useoptimized memory management.

When system resources (e.g.,CPU, RAM, I/O) are oversaturated, the system becomes overloaded, leading toincreased response timesandpoor application performance.

Option A (Gradual improvement of response time)is incorrect becauseperformance degrades under heavy load.

Option C (Error logging decreases)is unlikely; in most cases, errorsincreasewhen systems reach their limits.

Option D (Database size decreases)is unrelated to performance saturation.

Protocol-level scriptsmeasure theactual response times of network requests, making them ideal foranalyzing network latency, bandwidth issues, and server response times.

Option A (GUI scripts)measure user interactions, not network timing.

Option B (API scripts)measure API interactions but do not providedetailed network response time analysis.

Option C (HTTP scripts)measure web requests but lack low-level network insights.

Performance testsprimarily identifyresource bottleneckssuch asCPU saturation, memory leaks, network congestion, and database slowdowns.

Option B (Suitability issues)is afunctional requirement concern, not a performance issue.

Option C (Learnability concerns)relates tousability testing, not performance.

Option D (Accessibility requirements)falls undercompliance and usability testing, not performance testing.

Before running the next set of performance tests, it is crucial tounderstand the differences (delta) between the previous test results and the expected improvements. This ensures that:

The changes made by developers are properly validated.

Performance objectives are aligned with measurable improvements.

Option B (Adjust stakeholder expectations)is incorrect, as performance testing should focus on real data rather than adjusting expectations.

Option C and D (Realign objectives for milestones or time-to-market goals)are incorrect becausetest objectives should focus on technical accuracy rather than schedule constraints.
