Terraform infrastructure definitions are written in files with the .tf extension, commonly named main.tf. To create a new, empty file where infrastructure code can be added, the correct command is touch main.tf. This command creates the file without adding any content, allowing Scott to begin defining Docker infrastructure using Terraform syntax. The cat command is used to display file contents, not create files. The echo command prints text to standard output and does not create files unless output redirection is used. The command sudo main.tf is invalid and does not create files. Creating Terraform configuration files during the Release and Deploy stage supports Infrastructure as Code practices, enabling version control, repeatability, and security validation of infrastructure deployments. This approach allows DevSecOps teams to define, review, and deploy infrastructure in a consistent and auditable manner.

Azure Container Instances provide built-in logging capabilities that can be accessed using the Azure CLI. To retrieve logs from a deployed container instance, the correct command isaz container logsfollowed by the resource group and container name. The proper syntax requires double-dash parameters:--resource-groupand--name. In Erica’s case, the correct command is az container logs --resource-group ACI --name aci-test-closh. Options that use “az get container logs” are invalid because “get” is not a supported verb in this context. Option C uses incorrect single-dash flags, which do not match Azure CLI standards. Accessing container logs during the Code stage helps engineers validate application behavior, identify runtime errors, and ensure that security instrumentation such as RASP agents are functioning correctly before progressing further in the pipeline.

To inspect exposed ports for running Docker containers, the recommended approach is to first retrieve container IDs using docker ps --quiet and then pass them to docker inspect. The --format option allows selective output of container configuration details, including port mappings. The command docker ps --quiet | xargs docker inspect --format ': Ports=' correctly extracts port information for each container. Options that include the --all flag or incorrect formatting are not valid for this inspection use case. Checking exposed ports is an important activity in the Operate and Monitor stage because unnecessary open ports increase the attack surface and may violate container security best practices. Regular inspection helps ensure that only required ports are exposed, supporting secure runtime operations.

GitLab CI/CD pipelines are defined using a configuration file namedgitlab-ci.yml, which must be placed in the root directory of the repository. This file controls pipeline stages, jobs, and template inclusions. To integrate Checkmarx SCA using a predefined template, the template reference must be included in the root-level gitlab-ci.yml file so GitLab can load and execute the defined jobs automatically. The other filenames listed in the options are not recognized by GitLab as valid pipeline configuration files. Integrating SCA at the Code stage allows early detection of vulnerable open-source dependencies, reducing remediation cost and preventing insecure components from progressing further in the DevSecOps pipeline.

The practices described—access management, defense in depth, minimizing third-party dependencies, and securing weak links—are all architectural and design-level decisions. These controls are not merely coding techniques or configuration defaults but reflect security being embedded into the system’s blueprint from the earliest stages. This aligns directly with theSecure by Designprinciple, which emphasizes proactively designing systems to resist attacks rather than reacting to vulnerabilities later. Secure by implementation focuses on writing correct and safe code, secure by default focuses on initial configuration settings, and secure by communication addresses trust and confidentiality in communication channels. Orange International’s approach demonstrates a holistic security mindset that anticipates threats and integrates protective measures throughout the system architecture, making Secure by Design the correct choice.

SonarLint is a static code analysis tool designed specifically to be used inside developers’ IDEs, where it provides immediate feedback while code is being written. It highlights bugs, security vulnerabilities, and code smells and, importantly, providesclear remediation guidancethat explains why an issue exists and how it can be fixed. This aligns directly with Debra’s requirement to fix issues “before they exist,” meaning before code is committed to the repository. Arachni and OWASP ZAP are dynamic application security testing tools that require a running application and are typically used later in the pipeline. Tenable.io is a vulnerability management platform focused on infrastructure and application scanning rather than real-time developer feedback. By using SonarLint, developers receive continuous guidance during coding, supporting the shift-left security approach in DevSecOps and reducing the cost and effort of fixing vulnerabilities later in the lifecycle.

AWS CodeCommit is a fully managed, AWS-hosted source control service that allows teams to store and manage source code, binaries, and other digital assets securely in the cloud. It supports Git-based repositories and integrates seamlessly with other AWS DevOps services such as CodeBuild, CodePipeline, and CodeDeploy. CodePipeline orchestrates CI/CD workflows, CodeBuild performs build and test operations, and CodeDeploy automates application deployment—but none of these are version control systems. For organizations migrating from on-prem to AWS, CodeCommit provides fine-grained access control using IAM, encryption at rest and in transit, and high availability without the need to manage infrastructure. Using CodeCommit during the Code stage supports secure collaboration, version tracking, and centralized source control aligned with DevSecOps best practices.

HashiCorp Vault enables authentication mechanisms using the vault auth enable command followed by the name of the authentication method. To enable AppRole authentication, the correct command is vault auth enable approle. AppRole is specifically designed for machine-to-machine authentication, making it ideal for CI/CD tools like Jenkins. It allows applications to authenticate securely using role IDs and secret IDs instead of static credentials. The other options do not follow Vault CLI syntax and would result in command errors. Enabling AppRole during the Build and Test stage ensures that secrets are accessed securely and dynamically, supporting least-privilege access control and reducing the risk of credential leakage across the DevSecOps pipeline.

The practices described—user identification and authorization, auditing, defense-in-depth, data protection, integrity enforcement, and input validation—are core elements that are planned and architected into the system from the beginning. These controls reflectSecure by Design, which focuses on embedding security principles at the design and architecture stage rather than adding them later. Secure by implementation emphasizes coding correctness, secure by default focuses on default configurations, and secure by communication focuses on trusted communication channels. DWART’s approach shows a holistic security mindset that anticipates attacker behavior and integrates layered defenses and controls into the system blueprint. This aligns directly with Secure by Design, which aims to reduce systemic risk by ensuring the application’s foundational structure enforces security consistently across all components and use cases.

Chef InSpec executes compliance tests using the inspec exec command. When testing Azure infrastructure, InSpec requires a target specification using the -t flag with the Azure transport identifier azure://. The correct command is inspec exec inspec-tests/integration/ -t azure://. Options using exe instead of exec are invalid due to incorrect command spelling. Options that use the -it flag misuse command-line parameters that are not intended for target selection. Running InSpec tests in this way allows DevSecOps teams to validate that Azure resources comply with architectural, security, and regulatory requirements. Integrating these checks into the Build and Test stage ensures continuous compliance and reduces the risk of insecure infrastructure reaching production environments.
