Certification guide
The AWS Certified Solutions Architect – Associate (SAA-C03) validates that you can design solutions on AWS that are secure, resilient, high-performing, and cost-optimized – the four pillars that mirror the AWS Well-Architected Framework. It sits one step above the foundational AWS Certified Cloud Practitioner and is the most widely held AWS certification worldwide, a common gate for cloud engineer, cloud architect, and DevOps roles.
The target candidate is expected to have at least a year of hands-on experience designing cloud solutions using AWS compute, storage, database, and networking services. You are not expected to be a specialist in any one service – you are expected to know which service is the right tool for a scenario, and why the near-miss alternatives are not. Most questions are scenario-driven and multi-service, with a stated business or technical requirement that eliminates three plausible options.
The four domains
The exam is organized into four content domains. The percentages below are the official domain weightings from the current SAA-C03 exam guide – they are how AWS distributes the scored questions.
Design Secure Architectures
Domain 1 · 30%The largest domain and the single biggest reason candidates fail. Covers IAM (roles, policies, permission boundaries, IAM Identity Center, cross-account patterns), data protection with KMS and Secrets Manager, VPC network security (security groups, network ACLs, VPC endpoints), and edge and detection services such as AWS WAF, Shield, GuardDuty, Macie, and CloudTrail. Expect scenario questions where the wrong answer is a real service that almost fits but breaks a stated requirement.
Design Resilient Architectures
Domain 2 · 26%Multi-AZ and multi-Region availability, Auto Scaling, Elastic Load Balancing patterns, RDS Multi-AZ vs read replicas, Aurora Global Database, DynamoDB Global Tables, SQS and SNS for decoupling, Route 53 failover and health checks, and the four canonical disaster-recovery strategies (backup and restore, pilot light, warm standby, active-active) with their RTO and RPO trade-offs. Many questions turn on the difference between similar-looking services or between synchronous and asynchronous replication.
Design High-Performing Architectures
Domain 3 · 24%Choosing the right storage class (S3 tiers, EBS volume types, EFS, FSx), scaling compute (Lambda, Fargate, ECS, EKS, EC2 Auto Scaling, provisioned concurrency), database performance (ElastiCache, DynamoDB DAX, read replicas), and networking performance (CloudFront, Global Accelerator, placement groups, NLB vs ALB). Also covers data ingestion at scale with Kinesis, MSK, DataSync, and Storage Gateway. Trade-offs between latency, throughput, and cost are the recurring theme.
Design Cost-Optimized Architectures
Domain 4 · 20%The smallest domain but the one where practitioner intuition matters most. Covers EC2 purchasing options (On-Demand, Savings Plans, Reserved Instances, Spot, Dedicated Hosts) and when each is right, S3 storage classes and lifecycle policies, right-sizing with Compute Optimizer, cost visibility with AWS Budgets and Cost Explorer, and the recurring VPC-cost trap of NAT gateway data transfer that Gateway VPC endpoints for S3 and DynamoDB can eliminate.
How our practice exams work
Each set contains 65 fresh scenario-based questions, distributed exactly to the current SAA-C03 blueprint – 20 questions on secure architecture, 17 on resilience, 15 on high performance, and 13 on cost optimization. Sets are authored around a rotating enterprise vertical (general enterprise, healthcare, financial services, manufacturing, government, retail, SaaS, higher education, energy, and a mixed-vertical randomized simulator) so that practicing multiple sets exposes you to the widest possible spread of real-world scenarios rather than the same handful reworded.
Every question is written to a working-architect quality floor: three of the four options are plausible near-misses that a working practitioner would seriously consider, and the explanation names the tempting wrong answer and explains why the best answer beats it. That is how AWS themselves write the real thing, and it is the only style of practice that predicts real-exam performance.
AWS scores the live exam on a 100-to-1000 scale with a 720 cut. A scaled score is not a raw percentage, so we set the pass mark on each set at 72% as an honest working proxy, and a passing run here means genuine coverage across all four domains – not luck in the heavy ones.

Subscribe to startFrequently asked questions about SAA-C03
What is the AWS Certified Solutions Architect – Associate (SAA-C03) exam?
SAA-C03 is the current version of the AWS Certified Solutions Architect – Associate exam. It validates that you can design solutions on AWS that are secure, resilient, high-performing, and cost-optimized – the four pillars that mirror the AWS Well-Architected Framework. It sits one step above the foundational AWS Certified Cloud Practitioner and is the most widely held AWS certification worldwide.
How many questions are on the SAA-C03 exam?
The exam contains 65 items: 50 are scored and 15 are unscored items AWS uses to calibrate future exam forms, and you will not know which are which. Questions are a mix of multiple choice and multiple response, and most are scenario-driven and multi-service.
What is the passing score for SAA-C03?
AWS scores the live exam on a 100-to-1000 scale with 720 as the cut score. That scaled score is not a raw percentage, so as an honest raw-score equivalent we set the pass mark on each Certifym practice set at 72%.
How long is the SAA-C03 exam and how much does it cost?
The exam runs 130 minutes and costs $150 USD. It is delivered through Pearson VUE or PSI.
What experience do I need before taking SAA-C03?
The target candidate is expected to have at least a year of hands-on experience designing cloud solutions using AWS compute, storage, database, and networking services. You are not expected to be a specialist in any one service – you are expected to know which service is the right tool for a scenario, and why the near-miss alternatives are not.
How hard is the SAA-C03 exam?
The difficulty is in discrimination rather than recall. Most questions are scenario-driven and multi-service, with a stated business or technical requirement that eliminates three plausible options. The wrong answers are frequently real services that almost fit but break a stated requirement, so passing depends on knowing why the near-misses lose.
What domains does SAA-C03 cover, and how are they weighted?
Four domains: Design Secure Architectures (30%), Design Resilient Architectures (26%), Design High-Performing Architectures (24%), and Design Cost-Optimized Architectures (20%). Security is the largest domain and the single biggest reason candidates fail, so it should absorb the most study time.
How long is the SAA-C03 certification valid?
The credential is on a three-year renewal cycle, so plan to recertify within three years of passing.
How do I prepare for the SAA-C03 exam?
Work through scenario-based practice that matches the blueprint rather than flashcard recall. Each Certifym set contains 65 fresh scenario-based questions distributed exactly to the current SAA-C03 blueprint – 20 on secure architecture, 17 on resilience, 15 on high performance, and 13 on cost optimization – and each set is authored around a rotating enterprise vertical so that practicing multiple sets exposes you to the widest possible spread of real-world scenarios rather than the same handful reworded.
What is the difference between SAA-C03 and the AWS Certified Cloud Practitioner?
Cloud Practitioner is the foundational credential; SAA-C03 sits one step above it. Cloud Practitioner establishes AWS vocabulary and service awareness, while Solutions Architect – Associate asks you to choose between services under a stated requirement and defend the trade-off. SAA-C03 is a common gate for cloud engineer, cloud architect, and DevOps roles.
