This free study platform offers 72 structured lessons across 12 domains, 715 practice questions, domain-specific exams, and 10 full certification simulation variants to prepare for the CCA-F exam. It features spaced repetition, interactive quizzes, and knowledge mapping.

What is covered on the CCA-F exam?

The CCA-F exam covers 12 domains: Foundations and Core Concepts, Prompt Engineering, Context Engineering, Tool Use and Function Calling, Structured Outputs, Model Context Protocol (MCP), Claude Code, Claude Agents SDK, Agentic Architecture, Production Architecture, Reliability Engineering, and Multi-Agent Systems.

How many questions are on the CCA-F exam?

According to Anthropic, the CCA-F exam contains 60 questions to be completed within 120 minutes. The passing score is 720 out of 1000. Question types include multiple choice (30%), multiple select (20%), scenario-based (25%), architecture review (15%), and tradeoff analysis (10%).

How long does the CCA-F exam take?

The CCA-F exam allows 120 minutes (2 hours) to complete 60 questions. With 25% scenario-based questions, time management is critical. Candidates have approximately 2 minutes per question and should allocate more time to multi-step scenario and tradeoff analysis questions.

What is the passing score for the CCA exam?

The CCA-F exam requires a passing score of 720 out of 1000 points. The difficulty distribution is approximately 25% easy questions, 50% medium questions, and 25% hard questions. Domain practice exams on this platform require 70% to pass, while full certification simulations require 75%.

Is the Claude Certified Architect certification worth it?

The Claude Certified Architect certification demonstrates verified expertise in building AI applications with Claude. As organizations increasingly adopt AI agents and Claude-powered workflows, certified architects are positioned to lead architecture decisions, optimize production deployments, and implement best practices across multi-agent systems.

Claude Code is a CLI tool developed by Anthropic that brings Claude's coding capabilities directly into the development environment. It supports edit mode and plan mode, keyboard shortcuts, slash commands, and a skills directory. Claude Code accounts for approximately 20% of the CCA-F exam content.

How do Claude agents work?

Claude agents operate using an agentic loop: send a request to the Messages API, process Claude's response, execute any tool calls Claude requests, append the results, and repeat until Claude returns end_turn. The stop_reason field is the sole termination signal. Agentic architecture and the Agents SDK together account for approximately 27% of the CCA-F exam.

What is the Model Context Protocol (MCP)?

The Model Context Protocol (MCP) is an open standard developed by Anthropic and governed by the Linux Foundation's Agentic AI Foundation. It provides a three-layer architecture (Host, Client, Server) with three primitives: Resources (application-controlled), Tools (model-controlled), and Prompts (user-controlled), built on JSON-RPC 2.0.

What domains are tested on the CCA exam?

The CCA-F exam tests 12 domains: Foundations (2%), Prompt Engineering (12%), Context Engineering (8%), Tool Use and Function Calling (9%), Structured Outputs (8%), MCP (9%), Claude Code (20%), Agents SDK (12%), Agentic Architecture (15%), Production Architecture (0%), Reliability Engineering (5%), and Multi-Agent Systems (0%). The highest-weight domains are Agentic Architecture, Claude Code, and Prompt Engineering.

Can I take the CCA practice exam for free?

Yes. This platform provides free domain practice exams (15 questions, 20 minutes each) and 10 full certification simulation variants (65 questions, 130 minutes each). All practice tests include detailed explanations and track performance across attempts. No registration or payment is required.

How do I get started with Claude AI development?

Start with the Foundations domain: learn what Claude is, understand the Messages API, manage tokens, write system prompts, and configure sampling parameters. Claude offers three model tiers: Sonnet (general-purpose), Opus (complex reasoning with extended thinking), and Haiku (fast and cost-effective for simple tasks).
