Alexander Hamilton has been working as a senior DevSecOps engineer in an IT company located in Greenville, South Carolina. In January of 2012, his organization because a victim of a cyber security attack and incurred a tremendous loss. Alexander's organization immediately adopted AWS cloud-based services after the attack to develop robust software products securely and quickly. To detect security issues in code review, Alexander would like to integrate SonarQube with AWS Pipeline; therefore, he created a pipeline in AWS using CloudFormation pipeline template. Then, he selected SonarQube tool from the tools dropdown, provided the required stack parameters, and also provided email address for receiving email notifications of changes in pipeline status and approvals. He deployed the pipeline after entering the required information. What will happen when changes are committed in the application repository?

• A. Cloud Config event is created.
• B. Security Hub event is created.
• C. BinSkim event is created.
• D. CloudWatch event is created.

David, a DevSecOps engineer, is responsible for ensuring the security of his organization's software development lifecycle. During a security review, he notices that developers often embed API keys, database credentials, and other sensitive information directly into the application's source code. David warns that hardcoding credentials poses a serious security risk because attackers could extract sensitive information from leaked or publicly exposed repositories, and unauthorized access to critical systems could occur if credentials are compromised. To address this risk, David recommends implementing a secure system that allows applications to dynamically retrieve sensitive information at runtime without hardcoding them in the source code. Which of the following practices should be implemented to prevent developers from hardcoding secrets in the application's source code?

• A. Role-Based Access Control.
• B. Secrets Management.
• C. Secure Container Orchestration.
• D. Network Segmentation.

Lisa is a security engineer working in a DevOps team that follows a traditional security approach, where security testing occurs only at the end of the software development lifecycle. She notices that this approach leads to production delays due to extensive security rework. To resolve this, Lisa suggests integrating security into each phase of the development pipeline, ensuring vulnerabilities are identified and mitigated early. Which approach is Lisa advocating?

• A. Continuous Security Integration.
• B. Shifting Security to the Left.
• C. Security Operations Management.
• D. Risk-Based Security Enhancement.

Henrik Larsson, a DevSecOps engineer at a Gothenburg automotive manufacturer, wants his CI pipeline to fail the build if any Dockerfile violates best practices, such as running as root or using the "latest" tag for a base image. Which type of tool should Henrik integrate?

• A. Kubernetes NetworkPolicy
• B. Load balancer health check
• C. SIEM correlation rule
• D. Dockerfile linter (e.g., Hadolint)

Emma Rodriguez, a DevSecOps engineer at CyberNova Ltd., is responsible for securing a cloud-native e-commerce platform. Despite implementing security best practices during code commits, builds, and testing, the team recently discovered security vulnerabilities in the production environment, such as misconfigured cloud storage permissions and exposed API keys. To prevent similar issues, Emma decides to implement a final layer of security to identify vulnerabilities that are missed in pre-production testing activities.

• A. By performing deploy-time checks.
• B. By performing test-time checks.
• C. By performing commit-time checks.
• D. By performing build-time checks.
