CTAL-TTA Exam Dumps - ISTQB Advance Level Questions and Answers

Testing that focuses on confirming that data backup tapes can be retrieved and loaded within specified service levels is classified as Continuity Testing. This type of testing ensures that business processes can continue after a disruption, such as data loss or system failure.

Explanation: Continuity testing specifically addresses scenarios where operational capacity must be restored and verified within business continuity planning frameworks, such as disaster recovery processes.

Analysis:

Web-based testing tools perform various functions to ensure that websites are functional, user-friendly, and perform well.

B. b and c:

B. To provide information on the size of the web pages and on the time necessary to download them:

Web-based testing tools often analyze the size of web pages and their load times to ensure optimal performance and user experience.

C. To scan and check that no broken or missing hyperlinks are present on a website:

These tools can crawl websites to detect broken or missing hyperlinks, ensuring that all links are functional and lead to the correct destinations.

Explanation of Incorrect Options:

A. To generate HTML and XML that is compliant with industry standards such as W3C:

This is typically a function of development tools rather than testing tools.

D. To allow applications to be tested by simulating a mobile platform's runtime environment:

This describes a function of mobile testing tools, not general web-based testing tools.

E. To provide an engine that allows a user to execute a model describing a system's intended run-time behavior:

This is more related to model-based testing tools rather than web-based testing tools.

Statements about Performance Efficiency Testing:

A. Static Analysis tools can analyze code to identify performance bottlenecks.

True. Static analysis tools can examine the codebase to identify potential performance issues, such as inefficient algorithms or resource-intensive operations.

B. Code reviews are an effective way of detecting performance issues.

True. Code reviews can help identify inefficient code and potential performance bottlenecks, especially when reviewers have experience in performance optimization.

C. Scalability and Load testing are usually performed during the System test level.

True. These tests are typically conducted during the system testing phase to ensure that the application can handle expected load levels and scale appropriately.

D. Performance test execution cannot begin until a production-like environment is available.

False. While a production-like environment is ideal for accurate performance testing, preliminary performance tests can begin in a less similar environment, with full testing deferred until a closer approximation of production is available.

Correct Answer:

B. a and c

In a critical system that handles financial transactions with complex logic, ensuring thorough testing coverage is crucial. Here’s an analysis of the options:

A. Multiple Condition coverage: This provides the highest level of coverage by testing all possible combinations of conditions. However, it can be very time-consuming and is often impractical for complex systems due to the sheer number of test cases required.

B. MC/DC coverage: Modified Condition/Decision Coverage is a compromise between multiple condition coverage and decision coverage. It ensures that each condition within a decision has been shown to independently affect the outcome of that decision. This level of coverage is often required in safety-critical systems because it provides thorough testing without the excessive test case count of multiple condition coverage.

C. Decision coverage: This ensures that every decision (if statement) has been executed in both true and false directions. While useful, it may not be sufficient for complex systems where the interactions between conditions are critical.

D. Statement coverage: This ensures that every executable statement in the code has been executed. It is the most basic level of coverage and is generally not sufficient for complex systems, especially those that are critical to an organization’s finances.

Given the critical nature of the system and the need for a balance between thoroughness and practicality, the best option is B. MC/DC coverage. This ensures a high level of coverage that is more practical than multiple condition coverage while providing more assurance than decision or statement coverage.

Adopting an Acceptance Test-Driven Development (ATDD) approach can be particularly beneficial in scenarios where previous releases have suffered from misunderstandings among the development team and stakeholders regarding user story requirements. ATDD involves creating executable specifications before coding begins, which clarifies expectations and ensures alignment across the team. This method helps prevent issues seen in earlier stages by providing a clear, agreed-upon criteria for acceptance, thereby reducing the chances of future misunderstandings .

The provided pseudo code for the Answer program shows a WHILE loop that will always execute because the condition for the loop to terminate (a >= d) is never met within the loop's body. This results in an infinite loop. Additionally, since the value of 'b' is initialized with 'a + 10' and 'a' starts from a value that is read and then set to 2, 'b' will never be equal to 12. Therefore, the 'THEN' branch of the IF statement, which includes 'print(b)', is unreachable. These are control flow anomalies because they represent logic in the code that will not function as presumably intended.

Modified condition/decision testing (MC/DC) provides a higher level of coverage compared to other white-box testing techniques because it requires each condition in a decision to be shown to independently affect that decision's outcome. It is more rigorous than both decision testing (which only requires each decision's possible outcomes to be tested) and statement testing (which requires only each executable statement to be executed). Therefore, for a highly critical component, MC/DC is more appropriate as it ensures a more thorough assessment of the logic in the software component.

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.

Installability testing is usually conducted during the System Testing stage of the SDLC. It typically includes testing the installation process of the software to verify that it installs correctly across various systems and configurations. This type of testing often overlaps with functionality testing to ensure all functions are available post-installation, and usability testing to ensure that the installation process is intuitive and user-friendly.

Explanation: System testing encompasses a broad spectrum of testing practices intended to validate the software in its entirety, ensuring it meets the specified requirements and is ready for operation.

For a Medium risk mission- or safety-critical system, the best testing approach includes a combination of automated tests, exploratory tests, and manual black-box tests. Option B is the most comprehensive, advocating for automated tests to ensure reliability and repeatability, highly recommending exploratory tests to cover unforeseen scenarios, and recommending manual black-box tests to cover standard use cases. This multifaceted approach ensures thorough testing coverage essential for medium risk, safety-critical systems​​.
