Bitbucket provides a cloud-based source code management platform that supports collaboration, CI/CD integration, and secure code hosting. One of the key features offered by Bitbucket isfree unlimited private repositories, particularly beneficial for organizations developing proprietary software such as IoT applications. This allows teams to store source code securely without exposing it publicly while still enabling collaboration features like pull requests, issue tracking, and pipeline automation. The term “limited private repositories” is inaccurate because Bitbucket does not restrict the number of private repositories under its free offering; rather, user count limits apply. While Bitbucket also supports public repositories, the option that best represents its value to enterprise and product-based teams is unlimited private repositories. This capability aligns with DevSecOps practices by ensuring confidentiality of source code while enabling integrated planning, testing, and deployment workflows within a single platform.

Git post-commit hooks are executed automatically after a commit is successfully created. To trigger the Jenkins build job configured to respond to commits, Alex must create a valid Git commit using the correct Git command. The standard command to commit changes with a message is git commit -m "commit from terminal". Running this command records the changes in the repository and triggers the post-commit hook, which in turn initiates the Jenkins build. Commands using github commit are invalid because github is not a native Git command-line utility. The -b flag is also not used with git commit. Automating build triggers during the Code stage improves efficiency, reduces manual intervention, and ensures continuous integration is consistently enforced.

Gauntlt is a security testing framework written in Ruby and distributed as a Ruby gem. The correct way to install a Ruby gem is using the gem install command followed by the lowercase gem name. RubyGems are case-sensitive and standardized to lowercase naming conventions, which makes gem install gauntlt the correct command. The gems command does not exist in Ruby’s package management ecosystem, and using uppercase names such as Gauntlt can lead to installation failures. Installing Gauntlt allows DevSecOps teams to write human-readable security tests and integrate them into CI/CD pipelines, enabling automated and collaborative security validation during the Build and Test stage.

GitMiner is a Python-based tool, and like most Python projects, it manages its dependencies through a requirements file named requirements.txt. The correct way to install all dependencies listed in this file is by using the pip3 install -r requirements.txt command. The -r flag instructs pip to read package names and versions from the specified file and install them accordingly. The other flags shown in the options do not correspond to dependency installation from a requirements file and would result in command errors or unexpected behavior. Installing dependencies correctly is a prerequisite for running GitMiner successfully. During the Code stage, tools like GitMiner help identify hard-coded secrets and sensitive information early, reducing the risk of credential leakage and preventing security incidents later in the DevSecOps pipeline.

Interactive Application Security Testing (IAST) works by instrumenting the application at runtime, allowing it to observe both thesource code execution pathsand theHTTP requests and responsesflowing through the application. Because of this dual visibility, IAST can analyze every executed line of code (similar to SAST) while also monitoring real-time application behavior (similar to DAST). This unique capability enables highly accurate vulnerability detection with fewer false positives. The other options do not correctly explain how IAST achieves this hybrid analysis. Access to both code and HTTP traffic is what allows IAST to bridge static and dynamic testing techniques, making it highly effective across development, QA, and production environments.

The description matches AWSBugBust, which AWS positions as a gamified, team-based bug fixing challenge rather than a classic external “bug bounty” for finding vulnerabilities in AWS itself. The key hints are “fun-based solution for bashing bugs,” “encouraging team building,” and “friendly competition,” along with scoring points and awarding prizes. BugBust focuses on improving code quality by motivating developers to find and fix issues (often via static analysis findings) in languages like Java and Python. Participants earn points for remediations and compete on leaderboards, which aligns directly with Sarah “scored the highest points” and received a cash reward. The other names (BugFixer, BugFinder, BugHunt) are plausible-sounding but do not match the commonly referenced AWS gamified program described. In a DevSecOps context, this type of program supports culture by incentivizing secure coding habits, encouraging shared ownership of quality, and making remediation visible and rewarding across the engineering team.

ThreatPlaybook uses the playbook apply feature command to push user-story–driven threat models to the server. The -f flag specifies the path to the YAML file containing the defined user stories, abuser stories, and threat scenarios, while the -p flag specifies the target project. Option C correctly combines these parameters. The -y flag is invalid in this context, and options that misuse -t instead of -p do not correctly identify the project destination. Executing this command during the Plan stage enables teams to integrate threat modeling early, ensuring security risks are identified and addressed before development and deployment proceed.

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 Packer is an image automation tool that uses the packer build command to create machine images from configuration files written in HCL or JSON. When Robin defines her Docker image configuration in the file docker-ubuntu.pkr.hcl, the correct way to initiate the build process is by running packer build docker-ubuntu.pkr.hcl. This command reads the configuration file, initializes required plugins, executes defined builders and provisioners, and produces the final Docker image. The other options are syntactically incorrect because Packer does not support abbreviated flags such as -b or alternative verbs like -build. Building container images during the Build and Test stage ensures that images are reproducible, standardized, and compliant with organizational security requirements before deployment. Using Packer also supports immutability and reduces configuration drift, which are key principles in secure DevSecOps pipelines.

If a pre-commit hook script does not explicitly detect sensitive information or return a non-zero exit code, Git will treat the hook execution as successful. In this scenario, although the hook was made executable, Beth still managed to commit sensitive information. This implies that the hook either did not contain logic to detect such data or did not fail the commit upon detection. As a result, the script exited with0, allowing the commit to proceed. Exit code 0 always signals success to Git, while non-zero exit codes block commits. This highlights the importance of properly implementing security checks within hooks, not just enabling them. Making a hook executable is necessary, but it must also include correct validation logic to enforce security policies during the Code stage.
