ASQ Certified Software Quality Engineer Exam Practice Test

Answer : C

Cyclomatic complexity is a metric used to determine the number of linearly independent paths through a program's source code.

Definition: Cyclomatic complexity provides a quantitative measure of the complexity of a program, which is directly related to the number of test cases needed to achieve full branch coverage.

Calculation: It is calculated using the control flow graph of the program, where nodes represent blocks of code and edges represent control flow paths.

Test Cases: The metric indicates the minimum number of test cases required to cover all possible paths, ensuring that each statement is executed at least once.

Answer : D

Platform configuration testing ensures that the software works correctly across different hardware and software environments.

Objective: The primary goal is to verify that the software can handle all the required hardware and software configurations it is expected to run on.

Comprehensive Testing: This type of coverage involves testing the software on various combinations of operating systems, browsers, hardware devices, and other configurations to ensure compatibility and performance.

Identification of Issues: It helps in identifying issues that may arise due to differences in the environments, which can be crucial for software that needs to run on multiple platforms.

Answer : B

The daily scrum meeting (or daily stand-up) is a time-boxed event in agile methodologies designed for the team to synchronize activities and discuss any impediments.

Three Questions: During the daily scrum, team members typically address three questions: What did I do yesterday? What will I do today? Are there any impediments in my way?

Focus on Impediments: Discussing impediments is crucial as it allows the team to identify and address obstacles that may hinder progress, facilitating prompt resolution.

Short-Term Planning: The daily scrum focuses on the immediate tasks and issues, not on long-term planning or changes to the product roadmap.

Answer : A

An effective facilitator plays a crucial role in ensuring that team discussions are productive and inclusive.

Clarification: An effective facilitator clarifies key points made by team members, ensuring that everyone's contributions are understood clearly by the group.

Encouragement: Facilitators encourage participation from all team members, helping to draw out ideas and perspectives that might otherwise go unheard.

Neutrality: They maintain a neutral stance, focusing on the process of the discussion rather than contributing their own opinions or directing the outcome.

Answer : C

Causal analysis is a process used to identify the root causes of defects so that these causes can be addressed to prevent future defects.

Identification of Root Causes: Causal analysis involves techniques like root cause analysis (RCA) to systematically identify the underlying reasons for defects.

Preventive Actions: Once the root causes are identified, preventive actions can be designed and implemented to mitigate these causes, thereby reducing the likelihood of similar defects occurring in the future.

Continuous Improvement: Conducting regular causal analysis sessions contributes to continuous improvement in the development process, helping the team learn from past mistakes and enhance their practices.

Answer : A

Concurrently developing software, where multiple developers work on different parts of the codebase simultaneously, requires more rigid version control. This is because:

Managing Changes: Ensuring that changes made by one developer do not conflict with changes made by another.

Maintaining History: Keeping a detailed record of modifications to understand the evolution of the codebase and to revert changes if necessary.

Robust version control systems (VCS) like Git facilitate concurrent development by managing branches, merges, and conflict resolution effectively.

Answer : C

Component reuse in software development offers several advantages, one of the primary being the improvement of development costs. This means that:

Cost Efficiency: Reusing components reduces the need for developing new modules from scratch, saving time and resources.

Consistency and Quality: Reused components are typically well-tested and reliable, enhancing the overall quality of the software.

Reusable components help streamline the development process, leading to faster and more cost-effective software production.
