CTAL-TTA ISTQB Certified Tester Advanced Level Technical Test Analyst Free Practice Exam Questions (2025 Updated)

Considering the high load expected on the busiest day, particularly with a promotional offer like “buy 3 get 2 more free” on a pizza, addressing transaction concurrency in the architectural specifications is crucial. This ensures the system can handle multiple and simultaneous user transactions efficiently without data loss or service degradation. Proper handling of transaction concurrency is essential to maintain system integrity and responsiveness during peak times, which is a critical requirement for the online pizza ordering system on such a high-traffic day.

Model-based testing tools are specifically designed to simulate and verify various computational models, including finite state machines (FSM). FSMs are a core part of model-based testing, allowing the definition of system behavior under different inputs and states. Model-based testing tools use these machines to ensure that all states and transitions are covered during testing, providing a systematic approach to test automation and validation​​.

Analysis:

The significant non-functional defects recorded for the BestForFood system indicate issues that could be mitigated by appropriate non-functional testing strategies:

Portability Testing:

Ensures that the application can operate in different environments without issues. This could have addressed the defect related to the layout and navigation consistency across different websites (Defect A).

Compatibility Testing:

Ensures that the application works well with other systems and environments. This could have helped in preventing the performance issues noticed in the BestForPensions and BestForMortgages websites after the deployment of BestForFood (Defect B).

Explanation of Incorrect Options:

C. The time taken to diagnose, repair and re-test production defects: This is more related to maintainability and operational processes.

D. BestForFood performance impacted by data growth: This is better addressed through performance and scalability testing.

E. Installation time exceeding agreed timescales: This is related to deployment and operational efficiency.

Analysis:

To determine the correct keyword-driven input table for testing the enhancement to the social media application, we need to ensure the table adequately covers the following scenarios:

Adding existing members to a group.

Attempting to add non-existing members to a group and handling the error.

Removing members from a group.

Deleting groups only if no members are attached.

A. (Image A) - Assuming Image A correctly represents these scenarios.

Adding Members: The table should include steps to add both valid (existing) and invalid (non-existing) members to a group, ensuring the application correctly handles both scenarios.

Removing Members: The table should include steps to remove members from a group.

Deleting Groups: The table should include a scenario where a group with no members is deleted successfully.

Analysis:

When faced with incomplete documentation during test preparation, it is important to balance the need for thoroughness with the need to maintain project schedules.

B. To avoid delay to the project, attend the review as scheduled and raise the issue at the meeting:

This option ensures that the review proceeds as planned, preventing project delays. By raising the issue during the meeting, you can highlight the importance of the missing volumetric data and ensure it is addressed promptly.

Explanation of Incorrect Options:

A. Request that the meeting be delayed until the volumetric document has been drafted and examined by the reviewers:

Delaying the meeting might cause project delays and may not be necessary if the issue can be addressed in the meeting.

C. State that you are not a mandatory reviewer but request that both documents be sent to you once agreed:

This might cause you to miss important discussions in the review meeting.

D. Delay the review but limit schedule impact by presenting the volumetric document to the reviewers during the meeting:

This could still result in delays and does not ensure that all necessary information is reviewed in a timely manner.

Quantitative Questionnaires are the best elicitation technique for questioning a large number of stakeholders specifically to obtain information for non-functional acceptance criteria. This method allows for collecting measurable, numerical data from a broad audience efficiently, which is crucial for understanding and defining non-functional requirements such as performance, scalability, and usability

In the context of consumer electronics, where there is rapid growth in embedded software and pressure to minimize code size due to cost constraints, dynamic analysis can be particularly useful for improving system performance. Dynamic analysis involves examining the system's behavior during execution, which can provide insights into the efficiency of the code at runtime, memory utilization, and processing speed. In a high-end TV project where the use of ROM and RAM is under severe restrictions, dynamic analysis would be most appropriately applied to improve system performance, ensuring that the software runs efficiently within the available hardware resources. This supports the project context by contributing to the optimization of the software to run within the constraints of the microcontroller used, thereby potentially reducing costs.

Statements about Maintainability Testing:

A. It should start as soon as the draft design documents are available for review.

True. Maintainability testing can begin early in the development lifecycle, starting with reviews of design documents to ensure that maintainability concerns are addressed from the outset.

B. An application can be considered maintainable when static analysis and code review defects have been fixed.

False. While fixing defects identified by static analysis and code reviews improves maintainability, other factors such as documentation, ease of making changes, and regression testing must also be considered.

C. It tests the regression impact of software or environmental changes to an operational system.

False. This describes regression testing more than maintainability testing, which focuses on the ease of modifying the system and maintaining its performance.

D. It can be performed during Operational Acceptance Testing by multiple departments.

True. Maintainability testing can be part of operational acceptance testing (OAT), where different departments ensure that the system can be maintained and operated effectively.

E. It can be performed during User Acceptance Testing to ensure business processes can be maintained.

False. User acceptance testing (UAT) focuses on verifying that the system meets business requirements and user needs, not specifically on maintainability.

Correct Answer:

B. a and d

100% statement coverage means that every line of code is executed at least once during testing. Based on the provided pseudo-code and the test cases given:

Test 1 executes the MIN = B statement when A and B are equal.

Test 2 executes the MIN = A statement and skips the inner IF since B is not equal to 2*A.

All statements within the code have been executed by these two tests, hence no additional test cases are needed to achieve 100% statement coverage.

The code provided contains a potential endless loop. The loop is conditioned on the variable 'E' being less than 1 (IF E < 1), but within the loop, there is no operation that modifies the value of 'E'. Therefore, once the loop is entered, if the condition A > B holds true, the value of 'E' remains unchanged, leading to an endless loop situation. The decrement of 'A' in line 15 does not guarantee an exit condition for the loop, as it does not affect the value of 'E'. This is a control flow defect that could cause the program to hang or crash.

The true statement about test automation is that test automation levels can be influenced by and can constrain the frequency of code deployments. This reflects the understanding that while test automation can speed up the validation of code changes, enabling more frequent deployments, it also requires that the automation is sufficiently robust to handle the pace and scope of these deployments without becoming a bottleneck​​.
