CCDV-F Claude Code — 10 Questions

Question 1

A developer is using Claude Code and wants to ensure that specific sensitive directories are never accessed or indexed by the tool. Which mechanism should the developer use to enforce this restriction?

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

Accepted Answer

Create a .claudeignore file in the repository root.. Claude Code respects standard environment configuration patterns to manage scope. By utilizing a .claudeignore file, developers can explicitly define patterns for files or directories that the CLI agent should skip during repository analysis. This ensures data privacy and resource efficiency by preventing the agent from tokenizing large, irrelevant, or sensitive files, which is a critical practice for maintaining security in enterprise environments where codebases often contain configuration secrets.

Answer

Add the directory path to the .gitignore file.

Answer

Use the --exclude-path flag during every execution.

Answer

Modify the global Claude API key permissions.

Question 2

Refer to the exhibit. A developer encounters this error while running Claude Code. What is the most immediate and effective way to restore functionality for high-volume tasks?

Accepted Answer

Upgrade the subscription plan to Pro.. Claude Code operates within usage limits defined by the user's subscription plan. When these limits are reached, the agent cannot process further requests. Upgrading to a Pro plan increases throughput and token limits, which is the standard procedure for developers who require high-frequency interaction with the agent for complex refactoring or heavy codebase analysis tasks, ensuring seamless integration into their workflow.

Answer

Delete the .claude directory to reset the cache.

Answer

Switch to a different local machine.

Answer

Disable the .claudeignore file.

Question 3

Which THREE actions should a developer take to prepare a repository for optimal performance with Claude Code?

Accepted Answer

Create a comprehensive .claudeignore file.. Preparing a repository ensures the AI agent focuses only on relevant code, minimizing wasted tokens and reducing the risk of errors. Proper configuration is critical for performance because it narrows the scope of the agent's attention. By setting up ignore files, ensuring clear documentation, and maintaining a clean project structure, developers enable the model to provide higher-quality, more relevant assistance, which is essential for professional-grade software development workflows.

Answer

Upload the entire codebase to an external cloud IDE.

Answer

Disable the system shell for the terminal.

Question 4

Refer to the exhibit. What is the primary purpose of running this command in the terminal?

Accepted Answer

To check the current installed version.. Verifying the installed version is a fundamental troubleshooting and maintenance step for any CLI tool. It ensures that the developer is running the latest stable release, which is critical for accessing the newest features, security patches, and performance optimizations. Understanding how to check the version allows users to provide accurate information when reporting issues or ensuring compatibility with project requirements, which is a key practice for effective CLI tool management.

Answer

To initialize the local repository.

Answer

To list all available AI models.

Answer

To authenticate with the Anthropic API.

Question 5

A developer is using Claude Code to refactor a legacy Python module. They want to ensure the agent only modifies files within the 'src/core' directory and avoids touching sensitive configuration files. Which command or configuration approach best enforces these boundaries?

Accepted Answer

Add sensitive file patterns to a .claudeignore file in the root directory.. Claude Code respects the .claudeignore file, which functions similarly to .gitignore. By defining explicit path patterns in this file, developers can restrict the agent's file system visibility and modification scope. This is critical for preventing accidental alterations to sensitive infrastructure-as-code files or configuration secrets, ensuring the AI agent operates only within the designated application source code boundaries throughout the refactoring session.

Answer

Run the command with the --restricted-mode flag set to true.

Answer

Use the --whitelist flag followed by the path 'src/core'.

Answer

Invoke the agent using the --directory 'src/core' argument.

Question 6

Which TWO of the following are valid ways to provide feedback or context to Claude Code during an active coding session?

Accepted Answer

Provide clear, natural language instructions for refactoring style.. Claude Code utilizes a conversational interface that allows for dynamic guidance. Providing high-level architectural requirements or specific error-handling expectations helps the agent align with project coding standards. By iteratively refining these instructions, developers ensure the agent's output remains consistent with the team's needs, reducing the frequency of hallucinations or suboptimal code implementations throughout the project lifecycle.

Answer

Use the /help command to view current session capabilities.

Answer

Edit the system-prompt.txt file located in the project root.

Answer

Use the --force flag to override the agent's previous decisions.

Question 7

When configuring Claude Code for a new project, which THREE of the following practices are recommended to ensure optimal performance and security?

Accepted Answer

Ensure a robust .claudeignore file is used to exclude sensitive files.. Effective configuration is essential for maximizing the utility of Claude Code. Properly scoping the project, securing credentials, and providing relevant context allow the agent to perform at its peak. These practices minimize hallucinations, prevent accidental file modification, and ensure that the agent remains aligned with the project's specific coding standards and security requirements throughout the entire development lifecycle, creating a robust collaboration environment.

Answer

Hardcode sensitive API keys directly into the project's main script.

Answer

Give the agent sudo permissions to allow unrestricted tool usage.

Question 8

Which of the following is the standard way to exit a Claude Code session cleanly?

Accepted Answer

Type 'exit' or use the appropriate quit command as defined.. Proper session termination ensures that the agent saves any pending state or configurations and frees up local resources. Using the designated exit command allows the CLI tool to wrap up its current operations safely. This is a best practice for maintaining a clean terminal environment and ensuring that the interaction with the agent is finished without leaving behind hanging processes or incomplete operations.

Answer

Force close the terminal window using the OS kill command.

Answer

Delete the project directory to clear all traces.

Answer

Just start a new project in another folder.

Question 9

Which TWO of the following capabilities are built into Claude Code to assist developers during the coding lifecycle?

Accepted Answer

Direct execution of terminal commands for testing.. Claude Code is a multi-faceted tool that combines code generation with diagnostic and testing capabilities. By being able to read files, execute commands, and run tests, it provides a full-loop development experience. These integrated capabilities enable developers to offload significant portions of their workflow, from initial feature implementation to iterative bug fixing, all within the context of a single, project-aware agent session.

Answer

Automated code documentation and style guide generation.

Answer

Automated, persistent cloud-based code hosting.

Answer

Hardware-level debugging of physical devices.

Question 10

You are utilizing Claude Code to refactor a legacy Python codebase. After running a complex refactoring task, you realize Claude Code has created several unintended side effects in your project structure. What is the most efficient way to revert these changes while maintaining your current session context?

Accepted Answer

Run the 'undo' command to roll back the latest changes.. The 'undo' command in Claude Code is specifically designed to roll back the most recent file system modifications made by the agent. By utilizing this command, you can safely revert the unintended changes without terminating your active session or losing the conversation history. This ensures a seamless recovery process while allowing you to refine your instructions for the agent before re-attempting the refactoring task with improved constraints or clearer guidance.

Answer

Restart the CLI process and manually delete the modified files.

Answer

Execute the 'reset' command to clear the entire session history.

Answer

Use git checkout . to revert all changes in the repository.
