iSQI CTFL_Syll_4.0 Exam Questions

In Agile estimation sessions, particularly during Planning Poker, the goal is to reach a consensus on the effort required for a user story. The process encourages discussion and collaboration among team members to understand the story's requirements and complexities fully. Here's a breakdown of the options and why D is the correct choice:

Option A: Calculating the arithmetic mean of all estimates.

This method is straightforward but does not facilitate team discussion or consensus-building. It merely averages out the estimates without addressing the reasons behind the varying estimates. Thus, important insights and understanding of the task complexity might be missed.

Option B: Selecting the most frequent estimate value.

While this approach acknowledges the majority's opinion, it ignores the minority views, which might highlight significant aspects of the story that need consideration. It doesn't ensure that all perspectives are considered and discussed.

Option C: Calculating the mean of the most optimistic and pessimistic estimates.

This approach considers the extremes but again lacks the team discussion and consensus aspect. It also assumes that the extreme values alone can balance out the estimate, which might not always capture the true complexity or simplicity of the task.

Option D: Discussing the most pessimistic and optimistic estimates.

This approach fosters team collaboration and understanding. Memb4 and Memb6 explain their reasoning for the highest and lowest estimates, respectively, which can reveal different perspectives on the task's complexity. This discussion helps the team align their understanding and often leads to a more accurate and agreed-upon estimate in subsequent rounds.

In conclusion, the main goal of Agile estimation techniques like Planning Poker is to encourage team communication and collaboration to ensure that all aspects of the user story are considered. Option D best aligns with this goal by promoting discussion and consensus.

The tool described in the question supports the automated creation and installation of builds and the execution of various types of automated tests. This aligns with the practices and tools typically found in DevOps environments, which aim to integrate and automate the processes between software development and IT teams. DevOps tools facilitate continuous integration (CI) and continuous delivery (CD), enabling automated building, testing, and deployment of applications. Therefore, the correct answer is that this is an example of DevOps related tools.

When deciding on the order of test execution based on priorities and dependencies, the correct sequence should consider both the priority levels and any dependencies between test cases. Here's the analysis:

Test B has the highest priority (1) and depends on Test D.

Test D should be executed before Test B.

Test C has a medium priority (2) and depends on Test A.

Test A can be executed at any time since it has no dependencies.

Considering these dependencies and priorities, Test D should be executed first, followed by Test B. After that, Test A and finally Test C. Therefore, the correct sequence is D-B-A-C.

In a review process, the manager's responsibility is to ensure that sufficient time is allocated for the review activities. This includes planning and scheduling the review sessions, making sure that the team has enough time to conduct a thorough and effective review.

DevOps practices emphasize the importance of testing non-functional characteristics such as performance, security, and reliability. This focus ensures that the system not only meets functional requirements but also performs well under various conditions and is secure. DevOps promotes a continuous testing approach, which includes both functional and non-functional testing integrated into the development and deployment pipelines.
