AWS SAA-C03 Exam FAQs
What AWS services are most tested on SAA-C03?
Our 1,500+ questions focus on high-impact services: EC2 (15%), S3 (12%), RDS (10%), Lambda (9%), VPC (14%), and IAM (8%). We cover all services in AWS's official exam guide with scenario-based questions.
AWS Service Flashcards
Our 400+ AWS flashcards reinforce:
- Service limits (S3 buckets per account, Lambda timeout)
- Use cases (When to use Aurora vs DynamoDB)
- Pricing models (Spot vs On-Demand vs Reserved)
How do you simulate AWS architecture questions?
Our PRO version includes interactive architecture diagrams where you drag-and-drop AWS services to solve real-world scenarios, plus 65-question timed exams that mirror the actual test's difficulty.
AWS Architecture Builder
Interactive learning tools:
- Multi-AZ disaster recovery diagrams
- Serverless application workflows
- Hybrid cloud connectivity scenarios
What's the passing score for AWS SAA-C03?
AWS doesn't publish exact scores, but our data shows users consistently scoring 72%+ on our full-length practice exams pass the actual test. We weight questions by domain importance (Design: 30%, Implementation: 28%, etc.).
AWS Service Mind Maps
Our service connection maps help you:
- See how EC2 integrates with ELB, ASG, and EBS
- Understand cross-service security (IAM roles, KMS, S3 policies)
- Visualize data flows (S3 -> Lambda -> DynamoDB)
Do you include cost optimization strategies?
Yes! Our 150+ cost-focused questions cover Reserved Instances, Spot Fleet strategies, S3 storage classes, and the AWS Pricing Calculator - all critical for the Solutions Architect role.

- Cost Calculator trains for real-world constraints
AWS Scenario-Based Questions (PBQs)
Practice with real architecture challenges similar to AWS exam performance-based tasks.
PBQ 1: Highly Available Web Application
Scenario: Design a web application that must maintain 99.99% availability across 3 AZs. Budget is constrained, and traffic spikes 5x during promotions.
Recommended Architecture:
- Content Delivery: CloudFront with S3 origin for static assets
- Compute: EC2 Auto Scaling Group across 3 AZs with Application Load Balancer
- Database: RDS Multi-AZ deployment with read replicas
- Cost Controls: Mixed Spot/On-Demand instances, Reserved Instances for baseline
Exam Tip: AWS expects tradeoff awareness - this solution balances cost without compromising availability.
PBQ 2: Disaster Recovery Plan
Task: Your company requires RPO < 15 minutes and RTO < 2 hours for critical order processing systems. Current setup is single-region.
Key Components:
- Database: RDS Cross-Region Read Replicas with DMS for near-real-time sync
- Storage: S3 Cross-Region Replication (CRR) for order documents
- Compute: AMI copies with Auto Scaling in DR region
- DNS: Route 53 failover routing policy
Why this works: Meets RPO/RTO targets while using native AWS services.
PBQ 3: Serverless Image Processing
Scenario: Design a system that automatically resizes user-uploaded images to 3 sizes (thumb/medium/large) with these requirements:
- Process within 5 seconds of upload
- Store all versions cost-effectively
- Track processing metrics
Recommended Architecture:
- Trigger: S3 Event Notification on upload to source bucket
- Processing: Lambda invokes Elastic Transcoder with 3 presets
- Storage: Output to S3 with S3 Lifecycle rules moving to Glacier after 90 days
- Monitoring: CloudWatch custom metrics for processing time
Exam Tip: This serverless pattern appears in 18% of exams - know when to use Lambda vs Step Functions vs ECS.
PBQ 4: Multi-Account Network Design
Task: Connect VPCs across 3 AWS accounts (Dev/Test/Prod) with these constraints:
- Dev can access Test but not Prod
- All traffic must be audited
- Minimize management overhead
Implementation Steps:
- Connectivity: VPC Peering between Dev-Test only (no Prod)
- Auditing: VPC Flow Logs to CloudWatch Logs
- Management: AWS Organizations with SCPs restricting cross-account actions
- Alternative: Consider Transit Gateway for >50 VPCs
Why this matters: 23% of exam questions test multi-account networking and security.
PBQ 5: Oracle to Aurora Migration
Scenario: Migrate a 2TB Oracle database to Aurora PostgreSQL with minimal downtime (<15 mins). The database handles financial transactions.
