1. In CAS application troubleshooting, what does a high CPU utilization combined with low memory usage typically indicate? → Inefficient algorithms or compute-intensive processes
2. Which of the following is a key benefit of cloud-based application development? → Provides scalability and accessibility
3. What is the purpose of a test harness in automated testing? → To provide an automated environment with stubs and drivers needed to execute tests
4. What is the role of a database in data management? → To store and manage structured data
5. During CAS application troubleshooting, an error log shows repeated 'connection pool exhausted' messages. What is the most appropriate first step? → Increase the maximum connection pool size after analyzing current usage patterns
6. A new regulation impacts application development and configuration procedures. What should a CAS professional do first? → Ensuring compliance with current regulatory requirements and standards
7. When troubleshooting a memory leak in a CAS application, which tool category provides the most actionable data? → Heap dump analyzers
8. Which of the following best describes the General Data Protection Regulation (GDPR)? → A European data protection regulation
9. What is the recommended frequency for reviewing and updating system integration and data management protocols? → Monitoring outcomes through regular data collection and trend analysis
10. Which software development methodology requires writing tests before writing the application code? → Test-Driven Development (TDD)
11. What is the purpose of multi-factor authentication (MFA)? → To require multiple forms of user verification
12. What is the most common mistake professionals make when implementing security and compliance standards strategies? → Developing contingency plans for high-probability risk scenarios
13. In CAS application monitoring, which type of alert threshold strategy minimizes false positives caused by brief traffic spikes? → Sustained threshold alerts over a rolling time window
14. Which of the following is a best practice for data security in system integration? → Encrypting sensitive data
15. What is the recommended frequency for reviewing and updating application development and configuration protocols? → Monitoring outcomes through regular data collection and trend analysis
16. Which project management technique helps CAS teams identify which tasks must be completed before others can begin? → Critical path method (CPM)
17. What is the primary purpose of system integration? → To allow different systems to function together
18. What is the primary purpose of smoke testing? → To perform preliminary testing that reveals critical failures in a new build
19. Which compliance standard focuses on protecting personal healthcare information? → HIPAA
20. What does regression testing primarily aim to verify? → That previously working functionality still works after code changes
21. What does a wireframe represent in UI/UX design? → A rough sketch of UI layout and structure
22. What is the primary goal of UX design? → Enhancing user experience and usability
23. Which caching strategy stores precomputed results at the time data is written rather than when it is first requested? → Write-through caching
24. Which approach best reduces I/O wait time when a CAS application writes large volumes of log data? → Buffering log writes and flushing asynchronously in batches
25. A new regulation impacts system integration and data management procedures. What should a CAS professional do first? → Ensuring compliance with current regulatory requirements and standards
26. What best describes exploratory testing? → Simultaneous test design and execution where testers freely explore the software
27. Which technique is most effective for reducing application response time when database queries are the primary bottleneck in a CAS-certified application? → Implementing query result caching
28. Which tool or methodology is most appropriate for analyzing application development and configuration outcomes? → Maintaining professional boundaries while building collaborative relationships
29. What is a mock object in unit testing? → A simulated object that mimics real dependencies so tests run in isolation
30. In software delivery pipelines, what does CI/CD stand for? → Continuous Integration / Continuous Delivery
