FAQ

Quick answers for candidates preparing with explainx mock exams (not Anthropic support).

Anthropic's ~301-level proctored certification for solution architects building production apps with Claude Code, the Claude Agent SDK, MCP, and structured output. The official exam has 60 multiple-choice questions in 120 minutes, four scenario frames per sitting, and a scaled pass score of 720/1000.

Five weighted areas: Agentic Architecture & Orchestration (27%), Tool Design & MCP Integration (18%), Claude Code Configuration & Workflows (20%), Prompt Engineering & Structured Output (20%), and Context Management & Reliability (15%).

No. explainx.ai offers independent practice mock tests aligned to the public Foundations Exam Guide domains, task statements, and scenarios. Official registration and proctoring are through Anthropic Academy / Skilljar.

Lifetime access to all Claude Certified Architect mock tests on explainx.ai is $5 USD (one-time). Each attempt draws a shuffled subset from a bank of 1,000+ practice questions with explanations after submit.

You can browse certification and test pages without an account. Starting a timed mock test requires signing in and purchasing lifetime practice access for that program.

Eight mock tests per program including a full exam simulation, plus 1,000+ banked multiple-choice items. Programs include Claude Certified Architect (agentic architecture, MCP, Claude Code) and AWS GenAI Developer Professional (Bedrock, RAG, agents, governance).

Questions mirror the six official production scenarios: customer support agents, Claude Code development, multi-agent research, developer productivity, CI/CD with Claude Code, and structured data extraction.

Use Anthropic's Foundations Exam Guide and Academy courses for the proctored exam. Use explainx mock tests for timed MCQ practice, domain drills, and instant feedback — especially scenario-framed items and tradeoff questions.

A business-level, non-technical Google Cloud certification. The 90-minute exam has 50-60 multiple-choice questions across four domains — gen AI fundamentals, Google Cloud's gen AI offerings, techniques to improve model output, and business strategy — with no prerequisites required.

Microsoft's Associate-level certification for Azure AI engineers building generative AI apps and agents with Microsoft Foundry and Python. The 120-minute exam covers five domains with a minimum passing score of 700/1000.
