Frequently Asked Questions (FAQ)
Do I need SAA-C03 before SAP-C02?
There are no formal prerequisites. However, SAP-C02 assumes deep knowledge of everything in SAA-C03. Without it, the networking, security, and migration questions will be extremely difficult. SAA-C03 is strongly recommended as a foundation.
How does SAP-C02 differ from SAA-C03?
SAA-C03 tests your ability to recommend individual AWS services for specific requirements. SAP-C02 tests your ability to design entire enterprise architectures across multiple accounts, regions, and hybrid environments with competing constraints. The question style is also different: SAP-C02 scenarios are longer, involve more services, and almost always have two plausible answers.
When should I book the exam?
Book when your ExamOS Readiness Score is stable and above 80, and you have covered every domain at least once. The Readiness Score weights coverage, recency, and volume into a single number from 0 to 100.
Is SAP-C02 retiring?
Yes. AWS is replacing SAP-C02 with SAP-C03. Registration for the updated exam opens October 27, 2026, and the last day to take SAP-C02 is November 17, 2026. SAP-C03 becomes generally available on November 17, 2026.
If you pass SAP-C02 before the retirement date, your certification remains valid for the full three-year period. The credential does not expire early because a new exam version exists.
What is changing in SAP-C03?
SAP-C03 keeps the core architectural competencies of SAP-C02 but adds new content areas that reflect how the solutions architect role has evolved. The most significant additions are:
- Generative AI and agentic AI architectures. This includes Amazon Bedrock, AI agent architectures with Bedrock AgentCore, retrieval-augmented generation (RAG), Bedrock Guardrails, and human-oversight workflows for AI operations.
- Resilience engineering. Expanded coverage of AWS Fault Injection Service, AWS Resilience Hub, AWS Application Recovery Controller, and automated runbooks with Systems Manager.
- Cloud-native patterns. Serverless data pipelines, durable workflows with Step Functions, service mesh with VPC Lattice, container image security, and multi-tenant architectures.
- Post-quantum cryptography. ML-DSA and ML-KEM support in AWS KMS.
The domain structure is also changing from four domains to five, though AWS has not yet published the new weightings. Check the official exam guide on October 27 for the complete breakdown.
Should I take SAP-C02 now or wait for SAP-C03?
It depends on where you are in your preparation.
Take SAP-C02 if:
- You are within four weeks of being exam-ready
- You have already booked or are about to book
- Your employer or a project requires the credential now
- You want the certification without studying the new AI and resilience content
Wait for SAP-C03 if:
- You are early in your study plan (less than three weeks in)
- You are four to eight weeks from being ready and can absorb the additional content
- You want your credential to reflect the current exam blueprint
- You are targeting roles that list generative AI or resilience engineering skills
The core AWS architecture knowledge transfers between versions. If you switch from SAP-C02 to SAP-C03 mid-preparation, you will need to add the new content areas but will not lose the foundational work you have already done.
What should I do if I have already booked SAP-C02?
If you have a scheduled exam date before November 17, 2026, take it. A certification earned today is valid for three years and carries the same credential name on your resume. Employers see "AWS Certified Solutions Architect Professional," not the exam code.
If your scheduled date falls after the retirement date, you will need to reschedule for SAP-C03. AWS will contact candidates with affected bookings, but it is worth checking your appointment if you are unsure.
Where can I find the SAP-C03 exam guide?
The SAP-C03 exam guide publishes on October 27, 2026, the same day registration opens. Check the AWS Certification page on that date for the complete domain list, weightings, and preparation resources.
Until then, the SAP-C02 study plan you are following covers the foundational material that both exams share. The new content areas will build on top of that foundation, not replace it.
