312-97 Exam Questions & Answers

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, provides clear remediation guidance that 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.

In Go-based tool installation, the standard method to download, compile, and install a Go package is using the go get command followed by the repository import path. Since Matt has already ensured that Go version 1.8 or later is installed and that $GOPATH/bin is included in the system PATH, running go get github.com/michenriksen/gitrob will fetch the GitRob source code, build the binary, and place it in the appropriate bin directory. Options B, C, and D are invalid because go get does not accept multiple positional arguments in that manner, and go git is not a valid Go command. Installing GitRob during the Code stage enables DevSecOps teams to scan repositories for accidentally committed credentials, API keys, and other sensitive information, helping prevent data leakage from public repositories.

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.

Conjur policies define access controls, authentication rules, and secret variables, and they must be loaded into the correct policy branch. The conjur policy load command uses the -b flag to specify the policy branch and the -f flag to specify the policy file. To load a policy into the root branch, the correct command is conjur policy load -b root -f <file-name>. Options that reverse or misuse these flags are invalid and would either fail or load the policy incorrectly. Loading policies correctly during the Build and Test stage ensures that Jenkins pipelines can securely access secrets at runtime, enforcing centralized secret management, least-privilege access, and compliance with security requirements.

ThreatSpec is a command-line tool that follows standard Unix-style conventions, where commands are lowercase. To generate a threat model report after annotating source code, the correct command is threatspec report. Commands using incorrect casing or capitalization will fail because the CLI is case-sensitive. Options A, B, and C incorrectly capitalize either the command or the subcommand. Generating threat model reports during the Plan stage allows DevSecOps teams to continuously identify, document, and visualize security threats as the code evolves. This practice embeds threat modeling directly into the development lifecycle, enabling early risk identification and more secure system design decisions.
