The modules in the following table were all created two years ago as part of the same software project
Current Cyclomatic
Module Version Complexity
A 12 9
B 3 21
C 9 4
D 11 20
Which module is the most likely candidate for reengineering?
Looking at the table provided:
Module A has a version number of 12 and a cyclomatic complexity of 9.
Module B has a version number of 3 and a cyclomatic complexity of 21.
Module C has a version number of 9 and a cyclomatic complexity of 4.
Module D has a version number of 11 and a cyclomatic complexity of 20.
Given these details,Module Bstands out as the most likely candidate for reengineering for the following reasons:
The version number being 3 indicates that it has undergone fewer iterations of updates or fixes compared to the other modules, which might imply that it has legacy code that could benefit from reengineering.
When the number of failures found during acceptance testing is compared to the number of failures found after release, the result is a measure of
Measuring Test Effectiveness: This involves comparing the number of defects found during testing phases to those found after release.
Importance of Test Effectiveness: It provides insight into how well the testing process is identifying defects before the product reaches the customer.
Impact on Quality: High test effectiveness means most defects are caught during testing, leading to higher quality products and fewer post-release issues.
Which of the following problem-solving tools is most appropriate for breaking down ideas into progressively greater detail?
A tree diagram is a tool used to break down broad categories into finer levels of detail. It is particularly useful for:
Hierarchical Decomposition: Breaking down complex ideas or processes into manageable sub-components.
Problem Solving: Identifying root causes and exploring solutions systematically.
Project Planning: Defining tasks and sub-tasks in a structured manner.
The tree diagram starts with a single node and branches out into multiple nodes, each representing a more detailed aspect of the main topic.

When a team is defining a software metrics program, which of the following steps must be taken first?
Setting Goals: Before data can be effectively collected and utilized, it's essential to have clear goals. This ensures that the data collection process is aligned with the organization's objectives.
Importance of Goals: Establishing the data collection goal ensures that the team collects relevant and meaningful data, which can be analyzed to improve processes and products.
Sequential Process: After setting goals, the team can then determine what specific data to collect, how to collect it, and which metrics to report. This ensures a systematic approach to metrics program development.
The tester should complete which of the following sections of a problem report when documenting a test failure?
When documenting a test failure, the tester should complete the 'Steps to reproduce the failure' section of a problem report. This section is crucial as it provides a detailed account of the actions taken leading up to the failure, allowing developers to replicate the issue consistently. This replication is essential for diagnosing and fixing the problem effectively. Documenting the steps accurately ensures that all relevant information is conveyed, facilitating quicker resolution and better communication within the team. Reference:
