NEW QUESTION # 15
You are managing the testing efforts of an existing distributed system that manages inventories of automobile and light truck tires from multiple warehouses across the country. The system is being enhanced to track incoming restocking shipments at the point of entry to the warehouse and outbound sales shipments at the point of shipment from the warehouse, all of which are executed in real-time. System loads traditionally peak on Mondays due to built-up demand from the previous weekend.
You are preparing a presentation to the business stakeholders, outlining your performance testing strategy.
Which of the following is appropriate to present to this audience?
- A. A test plan that includes specific technical specifications for the computing hardware to be used for performance testing
- B. The risks that may exist due to platform differences between the test environment and the production environment
- C. Established HTTP response per second goals that will have acceptable minimum, maximum, and average response times
- D. A comprehensive list of support staff to be available during performance testing, including key members of the application development team
Answer: B
Explanation:
Business stakeholders are most concerned with risks that affect deployment and production stability. The primary risk in performance testing is that the test environment may differ from production, leading to misleading test results.
Option A (HTTP response goals) is too technical for a business stakeholder audience.
Option B (Hardware specifications) is relevant for technical teams, not business stakeholders.
Option C (Support staff details) is a logistical aspect, not a key performance testing risk for business decision-makers.
NEW QUESTION # 16
Which of the following performance script types measures network response times?
- A. Protocol-level scripts
- B. GUI scripts
- C. HTTP scripts
- D. API scripts
Answer: A
Explanation:
Protocol-level scripts measure the actual response times of network requests, making them ideal for analyzing 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 provide detailed network response time analysis.
Option C (HTTP scripts) measure web requests but lack low-level network insights.
NEW QUESTION # 17
Which of the following could lead to inconsistent performance test results?
- A. Virtual users running the same script while logged in as the same user.
- B. Concurrent scripts running and attempting to access the same data.
- C. Sequential scripts running and attempting to access the same data.
- D. Expected results were not verified with senior management.
Answer: A
Explanation:
If multiple virtual users execute the same script while logged in as the same user, it can cause data conflicts, session collisions, or cache interference, leading to inconsistent performance test results.
Option A (Concurrent scripts accessing the same data) may cause data locking issues, but this is a test setup concern rather than an inconsistency issue.
Option B (Sequential scripts accessing the same data) does not typically cause inconsistencies since they execute in order.
Option D (Verification with management) is unrelated to technical inconsistencies.
NEW QUESTION # 18
Which of the following is considered a common database protocol?
- A. SMP
- B. JUNIT
- C. MMS
- D. ODBC
Answer: D
Explanation:
ODBC (Open Database Connectivity) is a standard database protocol that enables applications to connect to and interact with databases regardless of vendor specifications.
Option B (JUNIT) is a unit testing framework, not a database protocol.
Option C (SMP - Symmetric Multiprocessing) relates to CPU architecture, not databases.
Option D (MMS - Multimedia Messaging Service) is related to mobile messaging, not database communication.
NEW QUESTION # 19
What is typically the result of oversaturation of system resources during performance testing?
- A. The size of the database will gradually decrease.
- B. Error logging will decrease.
- C. Response time will be slow under significant load levels.
- D. Response time will gradually improve over a period of time.
Answer: C
Explanation:
When system resources are oversaturated (e.g., CPU, RAM, or network bandwidth), response times will degrade because the system struggles to process requests efficiently. This is a key performance bottleneck indicator.
Option A is incorrect because response times do not improve under heavy load; they typically worsen.
Option C is incorrect because error logging may actually increase rather than decrease under stress.
Option D is incorrect because database size is independent of system saturation unless records are actively purged.
NEW QUESTION # 20
During which of the principal performance testing activities are the building blocks for larger, more complex tests created?
- A. During test planning
- B. During test implementation
- C. During test design
- D. During test completion
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 # 21
You have run a load test. When examining the metrics, you see that the virtual users experienced many timeouts and excessive wait times. The system throughput metrics exceeded expected results, even during peak times.
Based on your analysis, what conclusion should you draw?
- A. New test data is needed.
- B. Network infrastructure should be investigated.
- C. Processing speed is too slow.
- D. Virtual users are exhibiting impatient behavior.
Answer: C
Explanation:
If timeouts and excessive wait times occur, but throughput is high, this suggests that the system is unable to process requests fast enough. This points to slow processing speed due to CPU bottlenecks, memory limitations, or inefficient database queries.
Option A (Network infrastructure investigation) would be relevant if throughput was low or variable.
Option C (Impatient virtual users) is irrelevant; virtual users follow scripted behaviors.
Option D (New test data) does not address the core issue.
NEW QUESTION # 22
Which of the following can provide measurements for both individual and aggregated elements within a single performance test?
- A. Process optimization tracking
- B. Measuring underlying transactions
- C. Aggregated metrics
- D. Nested transactions
Answer: D
Explanation:
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.
NEW QUESTION # 23
Which of the following is the best description of spike testing?
- A. It focuses on the ability of the system to respond to quick and extreme changes in load.
- B. It focuses on the ability of the system to handle loads that are gradually increased to reach the expected maximum.
- C. It focuses on the ability of the system to handle loads that are at or beyond the expected peak load.
- D. It focuses on the ability of the system to meet future efficiency requirements.
Answer: A
Explanation:
Spike testing is a type of performance testing that evaluates how a system responds to sudden, extreme increases or decreases in load. It is designed to simulate unexpected surges in user activity or workload, such as flash sales, viral events, or cyberattacks.
Option A (Gradual load increase testing) describes load testing, not spike testing.
Option B (Handling expected peak load) describes stress testing, which pushes the system to or beyond its limits but does not focus on sudden changes.
Option C (Meeting future efficiency requirements) relates to capacity planning rather than spike testing.
Spike testing helps to identify system bottlenecks, resource allocation issues, and performance degradation when traffic surges unexpectedly.
NEW QUESTION # 24
When following the principal performance testing activities, when are resources allocated?
- A. During test execution
- B. During test evaluation
- C. During test planning
- D. During test completion
Answer: C
Explanation:
Resource allocation happens during the test planning phase, where hardware, tools, and personnel are assigned to the project. This ensures that performance tests are adequately supported.
Option B (Test execution) is when resources are actually used, not allocated.
Option C (Test evaluation) happens after execution to analyze results.
Option D (Test completion) focuses on documentation and reporting.
NEW QUESTION # 25
You are managing a project that is testing a system that manages a newly redesigned jet engine for heavy aircraft. Given the fact that this engine is specifically engineered to reduce noise, it is important that the software maintains enough thrust for lift for a period of 5 minutes without exceeding 87.5dB. The software must achieve this independent of other internal systems such as fuel or navigation management.
Given the risk for the ability of the aircraft to meet the noise abatement regulations while still being able to fly, when is the optimum time in the software lifecycle to apply the performance testing?
- A. Preferably at the end of unit testing
- B. Preferably during each phase in the lifecycle
- C. Preferably during system integration testing
- D. Preferably at the end of system testing
Answer: B
Explanation:
Performance testing should be integrated into every phase of the software lifecycle to ensure that critical performance requirements (such as thrust-to-noise ratio) are met early and continuously validated.
Option B (End of system testing) is too late, as issues may be costly to fix at that stage.
Option C (During system integration testing) is useful but not comprehensive enough.
Option D (At the end of unit testing) is incorrect because unit tests do not assess overall system performance.
NEW QUESTION # 26
What challenge must be considered when using crowds to emulate load generation?
- A. This type of load generation is more suitable for mainframe applications.
- B. This technique is more precise than other methods of load generation.
- C. The load generation will be difficult to reproduce.
- D. The load generation method is less sensitive to changes in the III.
Answer: C
Explanation:
Crowd-based load generation involves using distributed users (e.g., cloud-based testers or real users). The main challenge is that the load generation can be difficult to reproduce consistently due to variations in network conditions, device types, and user behavior.
Option B is incorrect because load generation methods should adapt to system changes.
Option C is incorrect since mainframe applications typically do not rely on crowd-based testing.
Option D is incorrect because crowd-sourced load testing is generally less precise than scripted load testing.
NEW QUESTION # 27
Which of the following is considered a common web service protocol?
- A. RTE
- B. SOAK
- C. HTTP
- D. REST
Answer: D
Explanation:
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.
NEW QUESTION # 28
What should be captured for batch processing performance metrics?
- A. Throughput and wait times
- B. Average percentage of network latency
- C. Number of records deleted
- D. Number of concurrent virtual users
Answer: A
Explanation:
For batch 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 to real-time transaction processing, not batch jobs.
Option D (Concurrent virtual users) applies more to load testing rather than batch performance.
NEW QUESTION # 29
Which of the following is a general principle of performance testing?
- A. Tests must be executable within the project timeframe.
- B. Test results must be comparable to tester expectations.
- C. Tests must align with the ideal outcome of stakeholders.
- D. Test results must vary when the tests are run repeatedly on an unchanged system.
Answer: A
Explanation:
Performance testing is time-sensitive and must be designed to fit within the constraints of the project timeline. If performance tests take too long to execute, they may not be feasible within a given sprint or development cycle. The results should be reproducible, meaning the same test on an unchanged system should yield the same results (making option C incorrect). While stakeholder expectations are important, performance tests should be objective and based on defined benchmarks rather than subjective expectations (making option D incorrect).
