Anthropic Claude Certified Architect - Foundations CCAR-F Prüfungsfragen mit Lösungen (Q162-Q167):

162. Frage
Your MCP server implements a check_availability tool that queries an external calendar API.
During testing, you encounter three error conditions: (1) the tool is called with a malformed request missing the required user_email parameter, (2) the calendar API returns a 404 because the specified user doesn't exist in the calendar system, and (3) the calendar API returns a 503 because the service is temporarily unavailable. How should each error be reported according to MCP's error handling design?

A. Report errors 1 and 2 as JSON-RPC protocol errors; report error 3 as a tool result with isError:
true.
B. Report all three as JSON-RPC protocol errors.
C. Report all three as tool results with isError: true.
D. Report error 1 as a JSON-RPC protocol error; report errors 2 and 3 as tool results with isError:
true.

Antwort: D

Begründung:
Errors caused by malformed requests (missing required parameters) violate the RPC protocol and should be reported as JSON-RPC errors. Errors returned by the external service (user not found, temporary unavailability) are valid tool execution results and should be reported as tool outputs with isError set to true, allowing the agent to handle them gracefully.

163. Frage
You are building developer productivity tools using the Claude Agent SDK. The agent helps engineers explore unfamiliar codebases, understand legacy systems, generate boilerplate code, and automate repetitive tasks. It uses the built-in tools (Read, Write, Bash, Grep, Glob) and integrates with Model Context Protocol (MCP) servers.
An engineer asks the agent to understand how the caching layer works before adding a new cache invalidation trigger. After initial Grep searches, the agent has identified that caching logic spans 15 files including decorators, middleware, and service classes (~8,000 lines total). What's the most effective next step for building understanding while managing context constraints?

A. Use the Read tool to sequentially load all 15 files, building complete understanding across the full caching implementation.
B. Use Glob to find files matching common caching patterns (cache.py, caching/), prioritize the largest files by reading them first, then check smaller files for gaps.
C. Analyze imports and class hierarchies to identify the base cache class, Read that file to understand the interface, then trace specific invalidation implementations.
D. Use Grep to search for "invalidate" and "expire" patterns across all files, then Read only those specific line ranges with minimal surrounding context.

Antwort: C

Begründung:
This top-down approach establishes the caching abstraction first, then follows only the relevant implementations. It builds architectural understanding without loading all 8,000 lines or relying on narrow keyword matches that may omit important control flow. Anthropic recommends scoping exploration to task-relevant code to avoid filling the context window with unnecessary file reads.

164. Frage
You are integrating Claude Code into your Continuous Integration/Continuous Deployment (CI/CD) pipeline. The system runs automated code reviews, generates test cases, and provides feedback on pull requests. You need to design prompts that provide actionable feedback and minimize false positives.
Your automated review generates many findings per pull request, but developer feedback shows that approximately half are dismissed as "not worth addressing." Analysis reveals that these findings are often technically accurate but involve minor style preferences or patterns that are acceptable in the project.
Before adding infrastructure complexity, what prompt-design change would most effectively reduce dismissals while maintaining detection of genuine issues?

A. Add the instruction: "Only report findings you are highly confident are genuine problems."
B. Define explicit reporting criteria that distinguish reportable bugs and security issues from minor style preferences and accepted local patterns.
C. Add a secondary classification model that filters findings according to predicted developer acceptance.
D. Ask Claude to rate each finding's confidence from 1 to 10 and include only findings rated 8 or higher.

Antwort: B

Begründung:
Option C defines the reviewer's actual objective instead of relying on an undefined notion of confidence. The prompt should identify reportable categories such as correctness defects, security vulnerabilities, data-loss risks, broken requirements, and meaningful performance regressions. It should also specify that cosmetic preferences, lint-enforced formatting, speculative refactoring, and intentional repository conventions must not be reported unless they cause concrete incorrect behavior.
Anthropic's Claude Code best-practices guidance recommends telling a reviewer to report gaps affecting correctness or stated requirements and to treat other observations as optional. Without such criteria, a reviewer asked to "find issues" will predictably return technically defensible but operationally low-value observations.

165. Frage
You are building developer productivity tools using the Claude Agent SDK. The agent helps engineers explore unfamiliar codebases, understand legacy systems, generate boilerplate code, and automate repetitive tasks. It uses the built-in tools (Read, Write, Bash, Grep, Glob) and integrates with Model Context Protocol (MCP) servers.
An engineer asks your agent to add comprehensive tests to a legacy codebase with 200 files and minimal existing test coverage. The engineer hasn't specified which modules to prioritize.
How should the agent decompose this open-ended task?

A. Systematically read all 200 files to create a complete function inventory before writing any tests, ensuring the testing plan accounts for every function before beginning.
B. Start writing tests for the first module alphabetically, using test failures and imports to discover related files organically.
C. Create a fixed testing schedule upfront based on directory structure, allocating equal effort to each top-level directory regardless of code complexity or business importance.
D. Use Glob and Grep to map codebase structure, identify heavily-coupled modules, create a prioritized plan for high-impact areas, and revise as dependencies are discovered.

Antwort: D

Begründung:
The task is open-ended because neither the critical modules nor the required testing sequence is known in advance. The agent should first use lightweight discovery tools to map the repository, locate existing tests, identify central modules, and determine which components have high fan-in, business significance, complex branching, or extensive external dependencies. It can then produce an initial risk-based testing plan and refine it as new dependency information appears.
Anthropic distinguishes predefined workflows from agents that dynamically control their processes and tool usage. Agents are appropriate when the required steps cannot be reliably hardcoded and must adapt to environmental evidence. During execution, they should obtain ground truth through tool results and use that feedback to determine subsequent actions.
Anthropic also identifies orchestrator-worker designs as suitable for complex coding and search tasks where the necessary subtasks depend on what the investigation reveals.

166. Frage
When implementing your lookup_order MCP tool, the backend sometimes returns errors-for example,
"Order not found" or temporary database failures. What is the correct pattern for communicating these errors back to the agent?

A. Log the error server-side and return an empty result to avoid confusing the model.
B. Return the error message in the tool-result content with the isError flag set to true.
C. Throw an exception from the tool handler so the agent framework can catch and log it.
D. Return a successful response with a status field indicating the error type.

Antwort: B

Begründung:
Option A follows the MCP error contract. An error originating during execution of a valid tool call-such as an API failure, input-validation problem, or business-logic failure-should be returned inside the tool result with isError: true. The content should explain what happened and, where possible, provide actionable recovery guidance.
The official MCP tools specification distinguishes tool-execution errors from protocol-level errors and specifies that execution failures are reported through tool results using isError: true. Anthropic's tool-using agent tutorial provides the equivalent Claude API pattern using is_error: true, allowing Claude to retry with corrected input, request clarification, or explain the limitation.
Option B falsely represents a failed operation as successful, weakening reliable failure detection. Option C deprives the agent of the information required to determine an appropriate recovery action. Option D may be converted into a tool error by some SDK runners, but uncaught exceptions are not the MCP-level response contract. The strongest implementation returns a concise, sanitized, actionable error result and separately records detailed diagnostics in server logs.
