⚠️ Don't Use SAA-C02 Practice Tests
If a practice test mentions "SAA-C02" anywhere, skip it. The domain weights changed, new services were added (like AWS Transfer Family, AWS Backup, and more Migration Hub questions), and the question style shifted toward more complex multi-service scenarios. Outdated questions build false confidence.

AWS SAA-C03 Domain Deep Dive: What You Need to Know
Your practice questions should cover these critical areas. If your current study resource skips any of them, you have gaps.
Domain 1: Design Secure Architectures (30%)
This is the largest domain and the one most candidates feel confident about — until they see the scenario-based questions. It's not enough to know "use IAM policies for access control." You need to know which IAM approach to use in complex, multi-account scenarios.
Key services to master:
- AWS IAM — policies, roles, identity federation, AWS Organizations SCPs
- AWS KMS — customer managed keys, key rotation, cross-region encryption
- VPC Security — security groups vs. NACLs, VPC endpoints (gateway vs. interface), PrivateLink
- AWS WAF & Shield — DDoS protection layers, rate-based rules
- Amazon Cognito — user pools vs. identity pools, when to use each
- AWS Secrets Manager vs. Parameter Store — cost, rotation, cross-account access
Domain 2: Design Resilient Architectures (26%)
Resilience questions test your understanding of AWS's shared responsibility model for uptime. The exam loves asking about multi-AZ vs. multi-region, and the right answer often depends on the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) given in the scenario.
Key concepts:
- Multi-AZ deployments — RDS Multi-AZ, ElastiCache Multi-AZ, EFS
- Auto Scaling — target tracking, step scaling, scheduled scaling, predictive scaling
- Decoupling — SQS (standard vs. FIFO), SNS, EventBridge, Step Functions
- Disaster Recovery — backup/restore, pilot light, warm standby, active-active
- Data replication — S3 Cross-Region Replication, Aurora Global Database, DynamoDB Global Tables
Domain 3: Design High-Performing Architectures (24%)
Performance questions are where the exam gets tricky. The "right" answer depends heavily on the workload characteristics described in the scenario. A compute-optimized instance is wrong if the workload is memory-bound, even if it's technically faster.
Key topics:
- Compute selection — EC2 instance families, Lambda vs. Fargate vs. ECS on EC2, placement groups
- Storage optimization — EBS types (gp3 vs. io2 vs. st1), S3 storage classes, S3 Transfer Acceleration
- Database selection — RDS vs. Aurora vs. DynamoDB vs. Redshift vs. ElastiCache
- Caching strategies — CloudFront, ElastiCache (Redis vs. Memcached), DAX, API Gateway caching
- Networking — Global Accelerator, Route 53 routing policies, Direct Connect, Transit Gateway
Domain 4: Design Cost-Optimized Architectures (20%)
Cost optimization sounds easy until you see the exam questions. They'll give you a scenario with specific uptime requirements and usage patterns and ask you to choose the cheapest architecture that meets all requirements.
Key topics:
- EC2 pricing — On-Demand vs. Reserved vs. Savings Plans vs. Spot vs. Dedicated
- S3 lifecycle policies — transition rules, Intelligent-Tiering, Glacier retrieval options
- Right-sizing — AWS Compute Optimizer, CloudWatch metrics, Trusted Advisor
- Serverless cost model — Lambda pricing, API Gateway, DynamoDB on-demand vs. provisioned
- Data transfer costs — inter-AZ, inter-region, VPC endpoints to reduce NAT Gateway costs
Try These Sample AWS SAA-C03 Practice Questions
Test your architecture knowledge with these exam-style questions. These cover the most commonly tested services and scenarios on the SAA-C03.
Question 1
A company runs a web application on EC2 instances behind an Application Load Balancer. The application stores session data locally on the instances. Users report losing their session when they are routed to a different instance. What is the MOST scalable solution to fix this?
Storing session data in ElastiCache for Redis is the most scalable solution. Sticky sessions (A) work but reduce the effectiveness of load balancing and cause issues during auto scaling. S3 has too much latency for session data. ElastiCache provides sub-millisecond access and centralizes session state independent of any instance.
Question 2
A company needs to migrate 50 TB of data from on-premises to Amazon S3. Their internet connection is 1 Gbps but is already 80% utilized by production traffic. The migration must be completed within 2 weeks. What is the MOST cost-effective solution?
With only 200 Mbps available (20% of 1 Gbps), transferring 50 TB would take roughly 23 days over the internet — exceeding the 2-week deadline. Direct Connect takes weeks to provision, making it too slow to set up. Snowball Edge can be ordered, loaded, and shipped within the timeframe. It's designed for exactly this scenario: large datasets with limited bandwidth.
Question 3
A company wants to deploy a highly available web application across two AWS Regions. The application should fail over to the secondary region if the primary becomes unavailable. The failover should be automatic with minimal data loss. Which combination of services should a solutions architect use? (Choose two)
Aurora Global Database provides cross-region replication with typically less than 1 second of replication lag, meeting the "minimal data loss" requirement. Route 53 failover routing automatically redirects traffic when health checks detect the primary region is down. RDS Multi-AZ is within a single region (not cross-region). DynamoDB Global Tables would work but isn't listed as an option.
Question 4
A company stores log files in an S3 bucket. The logs are frequently accessed during the first 30 days, occasionally accessed for the next 60 days, and rarely accessed afterward but must be retained for 7 years for compliance. What is the MOST cost-effective storage strategy?
The lifecycle policy matching access patterns is most cost-effective: S3 Standard for frequently accessed data (first 30 days), S3 Standard-IA for occasionally accessed data (next 60 days — IA is cheaper for infrequent access but still provides millisecond retrieval), then S3 Glacier for long-term retention. Option C skips the IA tier for occasional access. Intelligent-Tiering has monitoring fees that may not be optimal when access patterns are known.
Question 5
A solutions architect is designing a serverless application that processes images uploaded to S3. Each image must be resized into three different sizes. Processing takes 2-5 seconds per image. The application receives 10-1000 uploads per hour with unpredictable spikes. What is the BEST architecture?
The SQS + Lambda combination is the best serverless architecture for this use case. SQS provides a buffer for traffic spikes (decoupling), Lambda handles the 2-5 second processing well within its limits, and both scale automatically. Direct Lambda invocation (C) would work but lacks the buffering for spike protection. EC2 Auto Scaling adds unnecessary complexity for a serverless requirement. Fargate is overkill for 2-5 second tasks.
Question 6
A company has an on-premises application that needs to access objects in an S3 bucket. Company policy requires that the data must NOT traverse the public internet. The company has an existing AWS Direct Connect connection. What should a solutions architect recommend?
A public virtual interface (public VIF) on Direct Connect allows access to AWS public services like S3 without traversing the public internet. Despite the name "public," the traffic stays on the Direct Connect connection. S3 Transfer Acceleration still uses the public internet. A VPC endpoint is for resources within a VPC, not for on-premises direct access. A VPN adds unnecessary encryption overhead when Direct Connect already provides a private connection.
Question 7
A company runs a stateless batch processing workload that can tolerate interruptions. The workload runs for 4-6 hours and processes data from an SQS queue. What is the MOST cost-effective EC2 purchasing option?
Spot Instances offer up to 90% savings compared to On-Demand. The workload is perfect for Spot because it's stateless (can restart from where it left off using SQS), tolerant of interruptions, and not time-critical. SQS ensures no data is lost if an instance is interrupted — the message returns to the queue. Reserved Instances require a commitment and are better for steady-state workloads.
Question 8
A company wants to ensure that all data stored in Amazon S3 is encrypted at rest using keys managed by the company. The company also needs the ability to audit key usage. Which solution meets these requirements?
SSE-KMS with a customer managed key (CMK) meets both requirements: the company manages the key (can control access, rotation, and deletion), and AWS CloudTrail automatically logs all KMS key usage for auditing. SSE-S3 uses AWS-managed keys (company doesn't manage them). Client-side encryption works but doesn't provide built-in key usage auditing through CloudTrail.
Question 9
An application running on EC2 instances in a private subnet needs to download software patches from the internet. The instances should NOT be directly accessible from the internet. What should the solutions architect configure?
A NAT Gateway allows instances in private subnets to initiate outbound connections to the internet (for patches) while preventing inbound connections from the internet. It's placed in a public subnet and the private subnet's route table points 0.0.0.0/0 to the NAT Gateway. An Internet Gateway with public IPs would make instances directly accessible (violating the requirement). VPC endpoints only work for AWS services, not general internet access.
Question 10
A company's application uses a DynamoDB table with provisioned capacity. During peak hours, the application experiences throttling errors. During off-peak hours, the table is underutilized. What should a solutions architect recommend to handle the variable traffic pattern MOST cost-effectively?
On-demand capacity mode is designed for unpredictable or variable workloads. It automatically scales to handle traffic spikes without throttling, and you only pay for what you use. While DynamoDB auto scaling (D) can help, it reacts to load changes with a delay that can still cause brief throttling. On-demand handles instant spikes better. DAX is for read-heavy workloads (doesn't help with write throttling). Over-provisioning (A) wastes money during off-peak hours.

- Light review the day before — don't cram
💡 The 80% Rule
If you're consistently scoring 80%+ on full-length practice exams from multiple sources, you're ready for the real exam. If you're only hitting 80% on one source, try questions from a different provider to make sure your knowledge is solid, not just memorized.
Common SAA-C03 Mistakes and How to Avoid Them
1. Memorizing Services Instead of Understanding Architecture Patterns
The SAA-C03 doesn't test whether you know what S3 is. It tests whether you can choose between S3, EFS, and EBS for a specific workload. Focus on "when to use what" — not definitions.
2. Ignoring Cost Optimization
20% of the exam is about cost. Many candidates focus on making things work and forget about making them affordable. Always consider: Is there a cheaper way to meet the same requirements?
3. Not Reading Questions Carefully
The exam uses qualifiers like "MOST cost-effective," "LEAST operational overhead," and "BEST performance." Two answers might technically work, but only one matches the qualifier. Train yourself to identify these keywords.
4. Skipping Hands-On Practice
You can pass with just practice questions, but candidates who've actually built things in AWS find the scenario-based questions much easier to reason about. Use the AWS Free Tier — it's free for 12 months.
FAQ — Free AWS SAA-C03 Practice Questions 2026
Where can I find free AWS SAA-C03 practice questions?
ExamCert offers 300+ free SAA-C03 practice questions with detailed explanations and exam simulation. AWS Skill Builder also provides 20 official sample questions. Avoid brain dump sites — they violate AWS certification policies and can result in a permanent exam ban.
How many questions are on the AWS SAA-C03 exam?
The exam has 65 questions to be completed in 130 minutes. Of these, 50 are scored and 15 are unscored (used for future exam development). You won't know which questions are unscored.
What score do you need to pass the AWS SAA-C03?
You need a minimum scaled score of 720 out of 1000. AWS uses a compensatory scoring model, meaning your overall performance matters — not individual domain scores. Aim for 80%+ on practice tests to have a comfortable margin.
Is the AWS Solutions Architect Associate exam hard?
It's moderately difficult. The SAA-C03 tests architectural understanding, not just AWS knowledge. You need to evaluate trade-offs between cost, performance, security, and resilience — which requires deeper understanding than most associate-level certs.
How long should I study for the AWS SAA-C03?
Plan for 2-3 months at 10-15 hours per week. If you have hands-on AWS experience, 4-6 weeks may suffice. Complete 500-1000 practice questions and aim for consistent 80%+ scores on full practice exams before scheduling.
What's the difference between SAA-C03 and SAA-C02?
SAA-C03 replaced SAA-C02 in August 2022. Key changes: more emphasis on data migration/transfer services, hybrid architectures, AWS Organizations, and updated domain weights. Any practice test based on SAA-C02 is outdated — make sure yours says SAA-C03.
