At ValidExamDumps, we consistently monitor updates to the ISTQB CT-PT exam questions by ISTQB. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the ISTQB Certified Tester - Performance Testing exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by ISTQB in their ISTQB CT-PT exam. These outdated questions lead to customers failing their ISTQB Certified Tester - Performance Testing exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the ISTQB CT-PT exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
Which of the following is considered a common web service protocol?
REST (Representational State Transfer) is a widely used web service protocol that enables client-server communication over HTTP. It is commonly used in modern APIs and web applications for performance testing.
Option A (SOAK) refers to soak testing, which evaluates performance over an extended period.
Option C (HTTP) is a transport protocol, but REST is the actual web service architecture built on HTTP.
Option D (RTE) is not a web service protocol but may refer to Real-Time Enterprise systems.
Which of the following can provide measurements for both individual and aggregated elements within a single performance test?
Nested transactions allow performance tests to capture both individual and aggregated elements by grouping multiple related transactions and measuring their cumulative impact.
Option A (Aggregated metrics) provides summaries but lacks insight into individual elements.
Option B (Process optimization tracking) focuses on business process improvement, not test metrics.
Option C (Measuring underlying transactions) focuses only on individual transactions.
Which of the following is a typical performance risk associated with mobile, browser-based, and embedded real-time architectures?
Mobile and browser-based applications often rely on APIs for data retrieval and processing. Unexpected API load can cause latency issues, bottlenecks, and system crashes.
Option A (Hard disk speed) is not a major issue in cloud-based or mobile systems.
Option B (Misconfigured host machine) affects on-premise systems, not mobile/browser-based applications.
Option D (Internet connectivity issues) is a user-side issue, not a system performance risk.
At what point during performance testing does monitoring with the load testing tool begin?
Performance monitoring must begin simultaneously with test execution to capture system behavior in real-time. This ensures that bottlenecks and performance issues are identified immediately.
Option A (After testing is concluded) is incorrect because historical monitoring does not help in real-time analysis.
Option B (Before execution) is incorrect because monitoring needs active system load to measure performance.
Option C (Immediately after execution) is incorrect because it misses runtime metrics.
Which of the following is a static performance test?
A static performance test is a non-execution-based review that analyzes system architecture, network configurations, and other elements that affect 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.
