AWS Certified Solutions Architect Associate SAA-C03 Exam Guide

What Is the AWS Certified Solutions Architect Associate SAA-C03 Exam?

The SAA-C03 is the current version of AWS's Solutions Architect Associate certification. It checks whether you can design solutions on AWS using the AWS Well-Architected Framework, not just whether you've memorized service names. You're expected to look at a business scenario and pick the architecture that best balances security, resilience, performance, and cost.

AWS recommends at least one year of hands-on experience designing cloud solutions before you sit this exam. That doesn't mean you need a year of professional architect experience. Plenty of developers, sysadmins, and even students who've spent serious time in the AWS Free Tier building small projects go in prepared. If you're completely new to AWS, working through the Cloud Practitioner (CLF-C02) material first will make SAA-C03 far less overwhelming.

SAA-C03 Exam Format: Questions, Time, and Passing Score

Knowing the mechanics of the exam changes how you prepare, so don't skip this part.

• Total questions: 65 (50 scored, 15 unscored). AWS uses the unscored ones to test future questions, and you won't know which ones they are, so treat every question as if it counts.

• Time limit: 130 minutes, which works out to roughly two minutes per question.

• Question types: Multiple choice, with one correct answer, and multiple response, where you must select exactly the number of correct answers stated in the question. There's no partial credit on multiple response items, so these deserve extra attention during practice.

• Passing score: 720 out of a scaled 1000. AWS doesn't publish the exact percentage this represents, so don't waste time reverse engineering it. Focus on consistently scoring 80% or higher on quality practice exams instead.

• Exam fee: 150 USD, charged again for any retake. If you already hold an active AWS certification, you're eligible for a 50% discount voucher.

• Delivery: Available at Pearson VUE testing centers or as an online proctored exam from home.

• Validity: Three years from your pass date, after which you'll need to recertify.

One thing worth knowing if you're planning your prep timeline in 2026: AWS has been rolling out a newer SAA-C04 version, but SAA-C03 remains valid to sit through September 30, 2026. If your test date falls before then, you're still on solid ground with SAA-C03 materials.

SAA-C03 Exam Domains and Syllabus Breakdown

The SAA-C03 syllabus is organized into four content domains, each with a fixed weight. This is the single most useful table for planning your study time, because it tells you exactly where AWS expects your knowledge to be strongest.

Domain 1: Design Secure Architectures

This is the largest domain, and candidates who come from a development background tend to underestimate it. Expect scenario questions on IAM policies and permission boundaries, security groups versus network ACLs, KMS encryption for data at rest and in transit, AWS WAF and Shield, and AWS Organizations for multi-account security. Know how IAM policy evaluation logic actually works, not just what each service does in isolation.

Domain 2: Design Resilient Architectures

Here the exam tests whether you can build systems that survive failure without falling over. You'll need a solid grasp of multi-AZ and multi-Region deployments, Auto Scaling Groups, Elastic Load Balancing, decoupling patterns using Amazon SQS and SNS, and backup and disaster recovery strategies across S3, RDS, and DynamoDB.

Domain 3: Design High-Performing Architectures

This domain checks your ability to pick the right service for performance-sensitive workloads. Expect questions comparing EC2 instance families, choosing between DynamoDB and RDS based on access patterns, caching strategies with ElastiCache and CloudFront, and storage class selection across S3, EBS, and EFS depending on throughput and latency needs.

Domain 4: Design Cost-Optimized Architectures

The smallest domain by weight but increasingly relevant as companies watch cloud spend closely. You should be comfortable with Reserved Instances versus Savings Plans versus Spot Instances, S3 lifecycle policies, right-sizing with Cost Explorer and Compute Optimizer, and knowing when a serverless approach genuinely reduces cost versus when it doesn't.

How to Prepare for the AWS SAA-C03 Exam

Most candidates who pass on their first attempt follow a structure close to this. Adjust the timeline based on your existing AWS exposure.

1. Read the official AWS exam guide first. It lists every task statement AWS tests, and there's no substitute for knowing exactly what's in scope before you pick a course.

2. Take a diagnostic practice test early. Don't wait until you've finished studying. An early baseline tells you which domains need the most time.

3. Study domain by domain, weighted by exam percentage. For an eight week plan, that's roughly two and a half weeks on security, two weeks on resilience, two weeks on performance, and a week and a half on cost optimization.

4. Get hands-on in the AWS Free Tier. Reading about VPC peering is not the same as configuring one. Spin up EC2 instances, build a small VPC with public and private subnets, and set up an S3 lifecycle rule yourself.

5. Work through AWS whitepapers. The AWS Well-Architected Framework and Disaster Recovery of Workloads on AWS whitepapers map directly onto exam scenarios.

6. Drill practice questions in timed mode. Once you're consistently above 80% on section-based practice, switch to full timed mock exams that mirror the real 130 minute format.

7. Review every wrong answer, not just the right one. Understanding why the other three options are wrong is often what separates a pass from a near miss on exam day.

SAA-C03 Registration, Cost, and Validity

Registration happens directly through your AWS Certification Account at aws.amazon.com/certification. The exam costs 150 USD, plus applicable local tax depending on your country. If you don't pass, there's a mandatory 14 day wait before you can retake it, and you'll pay the full fee again, so it genuinely pays to walk in ready rather than treat your first attempt as a trial run. Once you pass, the certification stays valid for three years, and you can recertify either by retaking the current SAA exam or by earning a higher level AWS certification that renews your associate credential automatically.

Conclusion

The AWS Certified Solutions Architect Associate SAA-C03 exam rewards candidates who understand trade-offs, not just service names. Focus your study time on Domain 1 given its 30% weight, get real hands-on practice in the Free Tier, and use timed mock exams to build the pacing you'll need for 65 questions in 130 minutes. Once you're consistently scoring 80% or higher on realistic practice tests, you're in a strong position to book your exam date. From here, your next move is simple: pick a study resource, set a target date, and start working through Domain 1.
