Free AWS Practice Test — Core Services Before SAA-C03

Free questions on the AWS services the Solutions Architect Associate exam builds on — EC2, S3, Lambda, IAM, VPC and architecture fundamentals. This is groundwork rather than a mock exam: it is not weighted to the SAA-C03 blueprint, and we say so because a readiness score should tell you what was actually measured. For a blueprint-weighted score, the AI certifications below have one.

What this test covers

The SAA-C03 exam was updated in 2026 with new weighting on multi-region resilience patterns, serverless trade-offs (Lambda vs ECS vs Fargate), and cost-optimised architecture designs. Most practice question banks still reflect the pre-2026 blueprint. This free AWS CSA practice test is aligned to the current exam domains: Design Resilient Architectures, Design High-Performing Architectures, Design Secure Architectures, and Design Cost-Optimised Architectures. Answer 25 questions, get a readiness score from 0–100, and see your accuracy by domain. Score below 70? The AI Report ($19) builds a personalised study plan for your SAA-C03 weak areas.

  • Multi-Region Resilience — active-active vs active-passive, Route 53 routing policies
  • Serverless Architecture — Lambda trade-offs, event sources, ECS vs Fargate vs Lambda
  • VPC & Networking — Transit Gateway, PrivateLink, security groups vs NACLs
  • IAM & Security — cross-account roles, SCPs, permission boundaries
  • S3 & Storage — lifecycle policies, replication, intelligent tiering
  • RDS & Databases — Multi-AZ, read replicas, Aurora Serverless, DynamoDB
  • Cost Optimisation — reserved vs spot vs savings plans, right-sizing

Frequently asked questions

Is this test aligned to the SAA-C03 exam blueprint?
Yes. Questions are aligned to the four SAA-C03 domains: Design Resilient Architectures (26%), Design High-Performing Architectures (24%), Design Secure Architectures (30%), and Design Cost-Optimised Architectures (20%). The 2026 update added new emphasis on multi-region resilience and serverless trade-offs — both are covered here.
How is this different from the general AWS practice test?
The general AWS practice test covers CLF-C02 (Cloud Practitioner) and SAA-C03 foundations. This page focuses exclusively on SAA-C03 Solutions Architect material — architecture trade-off questions, multi-region patterns, and the cost optimisation domain that separates Associate-level candidates from Cloud Practitioner level.
Is this free? Do I need to sign up?
Completely free, no account required. After the test there is an optional AI Report ($19) that builds a personalised SAA-C03 study plan from your weak domains — but the test itself is always free.
How many questions are in this AWS CSA mock exam?
The full test (Hard mode) has 25 questions across the 7 SAA-C03 topic areas above. Easy mode covers foundational architecture concepts; Hard mode focuses on trade-off questions that appear in the associate exam.
What do I get at the end?
An instant readiness score (0–100), a pass likelihood estimate for SAA-C03, and a topic-by-topic accuracy breakdown showing your weakest exam domains.
