CCAR-F Claude Code Configuration and Workflows — 20 Questions

Question 1

A developer needs to ensure that Claude Code always follows a specific set of architectural guidelines for every session within a shared repository. Which configuration approach provides the most consistent enforcement for all team members?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Creating a .claude.json file in the repository root with custom instructions.. Project-level configuration files allow for the centralized enforcement of style guides and architectural rules within a specific repository. This ensures that every developer using Claude Code on the project operates under the same constraints, regardless of their global settings. It simplifies the onboarding process and reduces manual overhead during the initial prompt phase of each session.

Answer

Adding the guidelines to the global ~/.claude.json file on each developer's machine.

Answer

Providing the guidelines as a system prompt at the beginning of every interactive session.

Answer

Setting an environment variable named CLAUDE_INSTRUCTIONS in the local shell profile.

Question 2

A DevOps engineer wants to optimize the performance of Claude Code by limiting the files it indexes. Which TWO methods are valid for excluding files from the context and indexing process?

Accepted Answer

Defining patterns in a .claudeignore file located in the project root.. Excluding unnecessary files is critical for reducing token usage and improving the relevance of Claude's responses. By using standard ignore patterns and explicit configuration, engineers can ensure the model focuses only on pertinent source code. This optimization leads to faster processing times and lower costs during large-scale repository analysis.

Answer

Setting the CLAUDE_EXCLUDE environment variable to a comma-separated list of paths.

Answer

Renaming sensitive files to include a '.hidden' extension which Claude skips automatically.

Answer

Moving files to a directory named /temp which is hard-coded as an ignored path.

Question 3

When integrating Claude Code into a non-interactive CI/CD pipeline, how should the engineer handle the tool's requirement for user confirmation on file edits?

Accepted Answer

Use the --yes flag to bypass all confirmation prompts for tool execution.. Non-interactive environments require a different execution mode to prevent the tool from hanging while waiting for user input. By using specific flags, developers can authorize the model to perform its tasks autonomously. This is essential for automated refactoring, documentation updates, or automated bug fixing workflows within a continuous integration system.

Answer

Pipe a text file containing 'yes' into the standard input of the command.

Answer

Configure the 'auto_approve_all' setting to true in the global config file.

Answer

The tool detects the CI environment and automatically switches to non-interactive mode.

Question 4

Refer to the exhibit. Based on the provided configuration in .claude.json, how will Claude Code behave if the model attempts to run the command 'rm -rf ./dist'?

Accepted Answer

It will prompt the user for manual approval before running the rm command.. The 'auto_approve' list defines specific commands that can run without user intervention. Since 'rm' is not in that list, the tool defaults to its safety protocol. Even if 'danger_zone' is enabled, it usually refers to allowing the tool to even suggest such commands or enabling extended capabilities, but it does not grant blanket approval.

Answer

It will execute the command immediately because danger_zone is set to true.

Answer

It will fail with a configuration error because rm is not in the auto_approve list.

Answer

It will execute the command but log a warning to the console afterward.

Question 5

When configuring Claude Code for a team, which THREE authentication or authorization methods are supported for accessing the underlying Anthropic models?

Accepted Answer

Anthropic API Keys. Claude Code requires a valid connection to Anthropic's services to function. Supporting multiple authentication methods allows for flexibility across different corporate environments, ranging from individual developer keys to managed enterprise identities. Understanding these options is vital for architects designing secure workflows for their engineering organizations.

Answer

Direct SSH key pairing

Answer

OAuth2 through GitHub login

Question 6

How does Claude Code handle the discovery of a .claude.json file in a subdirectory of a project rather than the root?

Accepted Answer

It merges the subdirectory settings, with the subdirectory taking precedence over the root.. Claude Code uses a hierarchical configuration discovery mechanism. It looks for settings starting from the current working directory and moves up the folder tree. This allows developers to apply specific rules to sub-packages or components within a monorepo without affecting the global configuration of the entire project.

Answer

It ignores the file and only respects the .claude.json found in the git root.

Answer

It prompts the user to choose which configuration file to use for the session.

Answer

It fails to start and reports a 'multiple configuration files detected' error.

Question 7

An architect is setting up Claude Code for a high-security environment. Which TWO security practices are recommended for managing the tool's access and execution capabilities?

Accepted Answer

Use the 'auto_approve' feature only for read-only commands like 'ls' or 'grep'.. Security in agentic workflows is paramount because the tool has the ability to execute code and read sensitive files. Implementing a principle of least privilege and maintaining a clear audit trail are the cornerstones of a secure deployment. These practices protect the integrity of the codebase and the host system.

Answer

Disable the .claudeignore file to ensure full visibility of all project secrets.

Answer

Grant the Claude CLI administrative or 'sudo' privileges by default.

Answer

Store API keys in the .claude.json file within the shared repository.

Question 8

Which TWO keyboard interactions are standard within the Claude Code Terminal UI (TUI) to improve developer workflow?

Accepted Answer

Using the 'Up' and 'Down' arrow keys to navigate command history.. The TUI is designed to be highly interactive and efficient for developers who prefer staying in the terminal. Understanding keyboard shortcuts allows users to quickly navigate history and manage the interface without reaching for the mouse, which is essential for maintaining a high-velocity development pace during complex tasks.

Answer

Using 'Tab' to auto-complete file names within the prompt line.

Answer

Pressing 'Ctrl+S' to save the current session to a local JSON file.

Answer

Double-clicking a file path to open it in the default system editor.

Question 9

A Lead Architect is setting up a new enterprise repository and needs to ensure that Claude Code ignores specific files while maintaining security. Which TWO files or patterns should be explicitly configured in .claudeignore to optimize context and security?

Accepted Answer

Local .env files containing production secrets and API keys.. Configuring the local development environment correctly ensures that Claude Code has access to relevant source files while protecting sensitive data. The .claudeignore file is specifically designed to filter the project context, allowing architects to optimize token usage and prevent the model from processing irrelevant binaries or large log files that do not contribute to code generation logic.

Answer

Public documentation files in Markdown format.

Answer

Unit test files within the /tests directory.

Answer

The main package.json or requirements.txt files.

Question 10

A developer wants to change the default model used by the Claude Code CLI for all future sessions on their local machine. Which command should be used to persist this configuration globally?

Accepted Answer

claude config set -g model <model_name>. Managing the Claude Code lifecycle involves understanding how the CLI interacts with local configuration files to store user preferences and session data. Proper configuration allows for a seamless transition between different coding tasks by maintaining a consistent state. This ensures that the model always operates with the correct parameters and permissions, enhancing both productivity and security.

Answer

claude model set --default

Answer
