CCAR-F Claude Code Configuration and Workflows Practice Question
Which of the following describes the correct relationship between Claude Code's indexing process and the file system?
⚠ Common exam trap
Candidates often mistake the index for a 'cache' of the entire file content, rather than a semantic map used for efficient retrieval and navigation.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The index maps file content and structure to enable efficient retrieval.
Claude Code's indexing process is reactive and incremental. It scans the filesystem to build a semantic map of the codebase, which is stored locally. This index allows for efficient retrieval of relevant information without needing to re-scan the entire project every time a prompt is submitted. By understanding this relationship, developers can better manage their projects, knowing that changes to the filesystem are eventually reconciled into the index to maintain context accuracy.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The index is refreshed in real-time for every single file write operation.
Why it's wrong here
Constant, real-time re-indexing would consume massive amounts of CPU and I/O resources, severely degrading the performance of the local machine. Instead, indexing is handled in a more intelligent, incremental way that balances the need for current data with the need for system performance and resource efficiency.
- ✗
The index is a static snapshot taken only when the tool starts.
Why it's wrong here
A static index would become obsolete immediately as soon as a file is modified. The indexing process is designed to be dynamic and incremental, allowing the agent to stay updated with code changes throughout a session without needing to be restarted, which is vital for long-running, active development tasks.
- ✓
The index maps file content and structure to enable efficient retrieval.
Why this is correct
The index serves as a search index for the project's codebase. It maps the structure and content of the files into a format that the model can query efficiently. This enables the agent to locate relevant information across large projects without loading every file into the context window.
- ✗
The index is sent to Anthropic servers for processing and storage.
Why it's wrong here
Security and privacy require that the index remain local. Sending an index of the entire codebase to remote servers would be a major security risk and a violation of data privacy principles. Claude Code processes everything locally to ensure that proprietary code never leaves the developer's secure environment.
