The passing score is 75% (750/1,000 scaled score).

What are the domains on the AWS Certified Solutions Architect – Professional exam?

There are 4 domains: Design Secure Architectures, Design Resilient Architectures, Design Cost-Optimized Architectures, Design High-Performing Architectures. The official weights are Design Secure Architectures 27%, Design Resilient Architectures 24%, Design Cost-Optimized Architectures 25%, Design High-Performing Architectures 24%.

How should I use the domain weights when revising?

Weight by percentage, not by domain. 27% is the one where lost points cost you the most, and Certilum scores you per domain so you can see exactly where that is.

Does Certilum have practice questions for the AWS Certified Solutions Architect – Professional exam?

Yes: 75 questions in our bank for this certification, each tagged to the exam domain it belongs to, with the official domain weights applied.

AWS Certified Solutions Architect – Professional Exam Format

SAP-C02

Everything the official exam blueprint specifies: question count, time limit, scoring and the weight each domain carries. The AWS Certified Solutions Architect - Professional (SAP-C02) exam validates advanced technical skills and experience in designing distributed systems and applications on the AWS platform. It is intended for individuals who perform a solutions architect role with two or more years of hands-on experience designing and deploying cloud architecture on AWS. The exam covers four domains: designing secure architectures, designing resilient architectures, designing high-performing architectures, and designing cost-optimized architectures. Candidates must demonstrate the ability to evaluate cloud application requirements, make architectural recommendations for implementation, deployment, and provisioning, and provide best practices guidance throughout the lifecycle of a project. The exam includes multiple-choice and multiple-answer questions, as well as exam labs that test the ability to implement architectural concepts in a live AWS environment. Passing requires deep knowledge across compute, storage, networking, database, security, and cost optimization services in complex, multi-account, multi-region scenarios. This certification is widely recognized as the gold standard for experienced AWS architects and opens doors to senior-level roles and consulting opportunities.

Official domain weights

The percentage of the exam each domain carries. Weight your revision by these numbers, not by what you find hardest.

Domain	Weight	Topics	Practice Qs
Design Secure Architectures	27%	Design secure access to AWS resources using IAM, AWS Organizations, and SCPs Design secure application architectures using encryption (KMS, ACM, Secrets Manager) Design networking security controls (security groups, NACLs, network firewalls, VPC endpoints) +2 more	20
Design Resilient Architectures	24%	Design multi-tier and multi-region architectures for high availability Design disaster recovery strategies (backup and restore, pilot light, warm standby, multi-site active/active) Design scalable and elastic compute solutions (Auto Scaling, EC2, Lambda, containers, Spot Instances) +2 more	18
Design Cost-Optimized Architectures	25%	Design cost-optimized compute (Savings Plans, Reserved Instances, Spot Instances, Fargate) Design cost-optimized storage (S3 lifecycle policies, storage classes, EBS gp3, cold storage options) Design cost-optimized database and data transfer strategies +2 more	19
Design High-Performing Architectures	24%	Design cost-optimized compute, storage, and database solutions Design high-performance networking (CloudFront, Global Accelerator, Direct Connect, VPN, VPC peering, Transit Gateway) Design high-performance data processing pipelines (Kinesis, EMR, Glue, Redshift, Athena) +2 more	18

The heaviest domain is Design Secure Architectures at 27%, and that is where lost points cost you the most. Certilum scores you per domain so you can see the difference between a knowledge gap and a formatting problem.
