ISTQB Certified Tester - Performance Testing Sample Questions (Q30-Q35):
NEW QUESTION # 30
Which of the following is a typical performance risk associated with mobile, browser-based, and embedded real-time architectures?
Answer: D
Explanation:
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.
NEW QUESTION # 31
Which of the following is a key reason to include ramp-up and ramp-down periods in a performance test?
Answer: C
Explanation:
A ramp-up period in a performance test gradually increases load over time, and a ramp-down period does the opposite. This prevents sudden surges in system load, making test results more realistic.
Option A (Ensuring transactions complete in a time window) is incorrect because ramp-up/down periods do not control transaction timing.
Option C (Providing a buffer for slow transactions) is incorrect because ramp-up/down is about load balancing, not transaction timing.
Option D (Keeping all virtual users active throughout the test) is incorrect because ramp-down periods reduce users gradually.
NEW QUESTION # 32
You are heading the testing effort for a system that manages the air/fuel ratio of direct-injection fuel devices built specifically for high-altitude rescue helicopter engines. At altitude, the system must be able to perform in order to make enough air/fuel ratio adjustments per millisecond between fuel and both an on-board source and available ambient air in order to prevent an engine stall due to oxygen starvation. The system is following a sequential development lifecycle.
For this safety-critical software, when is the appropriate point in the lifecycle to identify and define the performance goals?
Answer: C
Explanation:
For safety-critical software, performance goals must be identified as early as the requirements phase. This ensures that performance constraints are well understood and accounted for throughout development.
Option A (After test readiness but before system testing) is too late, as requirements should be defined before coding begins.
Option C (During the concept stage) is too early, as details may not be concrete.
Option D (During software design) is useful but should be preceded by a proper definition during the requirements phase.
NEW QUESTION # 33
During which of the principal performance testing activities are the building blocks for larger, more complex tests created?
Answer: B
Explanation:
Test implementation is the stage where smaller test components are created and assembled into larger test scenarios. This phase includes scripting, test data preparation, and configuring load profiles.
Option A (Test completion) involves analyzing results, not building tests.
Option B (Test planning) focuses on strategies and objectives, not test creation.
Option C (Test design) defines test scenarios and cases, but the actual building happens in implementation.
NEW QUESTION # 34
Which of the following is considered a characteristic of stress testing?
Answer: C
Explanation:
Stress testing is designed to evaluate how a system behaves under extreme conditions, often exceeding its design limitations. The goal is to identify bottlenecks, memory leaks, and failures that occur beyond normal operating conditions.
Option A is incorrect because it refers to resilience testing, which focuses on recovery rather than stress beyond limits.
Option B is incorrect as it describes load testing, which measures performance under expected loads.
Option C is incorrect since determining the maximum transactions is a feature of capacity testing, not stress testing.
NEW QUESTION # 35
