CCDV-F Claude Code — All Questions With Answers

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?

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.

Question 11

A developer is using Claude Code in a monorepo. They want to ensure that the agent never modifies files in the `legacy/` directory, which contains deprecated code. They also want to allow the agent to run any command in the `src/` directory. Which configuration approach best achieves this?

Accepted Answer

Add a `permissions` section in `settings.json` that denies write access to `legacy/` and allows commands in `src/`.. The correct approach is to configure permissions in `settings.json`. This file allows granular control over what Claude Code can and cannot do. By denying write access to `legacy/`, you prevent accidental modifications, while allowing commands in `src/` maintains productivity. Other methods like `.claudeignore` or `CLAUDE.md` are not designed for enforcement and may not reliably prevent edits.

Answer

Create a `.claudeignore` file listing `legacy/` and rely on Claude Code to skip those files during edits.

Answer

Use a `CLAUDE.md` file with a rule: 'Do not edit files in legacy/'. Claude Code will enforce this rule automatically.

Answer

Set the `CLAUDE_CODE_READ_ONLY` environment variable to `true` for the entire project.

Question 12

A developer wants Claude Code to run a series of commands to set up a new development environment, but they are unsure which commands are safe to execute automatically. Which feature allows the developer to control which commands Claude Code can run without prompting?

Accepted Answer

The `/config` command, which opens a settings menu to define allowed and denied commands.. The `/config` command provides an interactive way to set which commands Claude Code can run automatically. It allows developers to define allowlists and denylists, ensuring that only trusted commands execute without prompting. Other options either do not exist, disable all safety, or are not intended for permission management.

Answer

The `/permissions` command, which toggles between strict and permissive modes.

Answer

The `--dangerously-skip-permissions` flag, which disables all permission checks.

Answer

The `CLAUDE.md` file, where commands can be listed with an `allow:` prefix.

Question 13

During a refactor, Claude Code proposes a broad edit that touches twelve files, including generated protobuf stubs under `gen/`. The developer wants to let Claude Code proceed on the hand-written source files but must ensure the generated stubs are never modified by the agent in this or any later session. Which approach best satisfies this requirement?

Accepted Answer

Add `gen/` to `.claudeignore` and add a permission rule denying edits to that path.. Durable protection of generated artifacts requires excluding them from context and denying write permissions at the Claude Code level. Combining `.claudeignore` with a deny rule prevents both accidental reads that could mislead the agent and any future write attempts, unlike one-time denials or editor settings that do not constrain the agent's own tools across sessions.

Answer

Deny the current edit and re-prompt Claude Code to only edit source files.

Answer

Set the editor to read-only mode for the `gen/` directory before starting the session.

Answer

Commit the generated stubs so Claude Code treats them as read-only.

Question 14

A developer is using Claude Code to implement a new feature. They want to ensure that Claude Code adheres to the project's coding standards and avoids modifying certain files. Which TWO of the following practices help achieve this? (Choose two.)

Accepted Answer

Configure command permissions to deny access to certain files or directories.. Adding a `CLAUDE.md` file with coding standards and configuring command permissions to deny access to certain files are both proactive measures that guide Claude Code's behavior. They provide persistent, enforceable rules that help maintain code quality and protect sensitive files. Other options either do not exist or are too restrictive.

Answer

Run Claude Code with the `--read-only` flag to prevent any modifications.

Answer

Manually review every edit before applying it and reject any that violate standards.

Answer

Use the `--no-edit` flag to prevent Claude Code from making any file changes.

Question 15

A developer is about to let Claude Code modify a production-critical configuration file. They want to review each individual edit as a diff and approve or reject it before it is written to disk. Which Claude Code behavior or setting supports this workflow?

Accepted Answer

Setting the permission mode to `plan`, which makes Claude Code propose changes and wait for approval before applying edits.. Plan mode is designed for review-before-execution workflows. Claude Code outlines what it intends to do and waits for the developer to approve before carrying out edits, which lets the developer inspect diffs and accept or reject them. Denying the file blocks all changes, skipping permissions removes review, and reading a file only shows current content without an approval gate.

Answer

Relying on the `Read` tool, which shows the file contents before Claude Code edits it.

Answer

Using the `--dangerously-skip-permissions` flag so edits are applied without interruption.

Answer

Adding the file path to a `deny` list in `.claude/settings.json` so Claude Code cannot modify it at all.

Question 16

Which TWO of the following capabilities are native to Claude Code when operating in a repository?

Accepted Answer

Execution of shell commands to test and verify code.. Claude Code is designed to act as an autonomous engineer within the local development environment. Its core strengths include the ability to execute shell commands to verify changes and the capacity to read the codebase to provide context-aware suggestions. Understanding these native capabilities is vital for developers to delegate tasks effectively without manually performing every verification step, thereby accelerating the software development lifecycle while maintaining code quality through automated testing.

Answer

Autonomous deployment of code to production servers.

Answer

Persistent storage of user source code on Anthropic servers.

Answer

Automatic configuration of cloud infrastructure providers.

Question 17

What is the primary purpose of the 'claude' command-line interface tool?

Accepted Answer

To act as an autonomous agent for local code interaction.. The primary objective of the Claude Code CLI is to serve as an interactive AI agent that integrates directly into the developer's terminal. It bridges the gap between natural language intent and local file manipulation. By understanding the tool's purpose, developers can leverage it to automate repetitive coding tasks, debug issues in real-time, and maintain context across a project, significantly reducing the cognitive load involved in navigating complex codebases.

Answer

To host a web server for displaying AI documentation.

Answer

To manage remote server configurations exclusively.

Answer

To replace the git version control system.

Question 18

When Claude Code executes a shell command that requires user intervention (such as an interactive prompt), how does the agent typically handle this situation?

Accepted Answer

It pauses the agent and waits for human input.. Handling interactive shell commands is a design challenge for autonomous agents. Claude Code is built to be safe and predictable. It monitors the output of the shell and, when it detects an interactive prompt that it cannot resolve autonomously, it pauses execution and waits for the user to provide input. This design prevents the agent from hanging indefinitely or making dangerous, unconfirmed assumptions in sensitive environments.

Answer

It automatically guesses the correct input.

Answer

It terminates the process and reports an error.

Answer

It forces the command with the -y or --force flag.

Question 19

Which THREE of these actions are considered safe and standard for Claude Code to perform during an interactive session?

Accepted Answer

Reading and summarizing codebase files.. Claude Code is built with safety as a priority. It is expected to handle file editing, command execution, and code review as part of its normal operation. Understanding these standard actions allows developers to trust the agent's output and integrate it into their workflow efficiently. By focusing on safe, verified, and transparent interactions, the agent maintains its role as a helpful assistant while minimizing risks associated with uncontrolled automation in a local project.

Answer

Deleting arbitrary user files without asking.

Answer

Exfiltrating environment variables to remote servers.

Question 20

How does Claude Code maintain context over a long-running conversation in the terminal?

Accepted Answer

It keeps state in memory and local configuration.. Claude Code utilizes a stateful management system that tracks the conversation history, recent file changes, and the current project state. This allows the model to reference previous suggestions, understand the current file structure, and build upon earlier tasks, which is critical for consistent, multi-turn interactions. By managing this context effectively, the tool provides a cohesive experience that mimics a human pair programmer, ensuring that the agent remains helpful throughout complex, multi-stage development projects.

Answer

It stores all conversation history in the git index.

Answer

It clears all history every time a command is run.

Answer

It relies entirely on the terminal scrollback buffer.
