AWS SAA-C03 Exam Scenarios
🗺️ The SAA-C03 Knowledge Matrix (Categorized) #
I have categorized my deep-dive analyses into the four official AWS domains. Use this map to identify your weak spots and master each pillar of the AWS Well-Architected Framework.
🛡️ Domain 1: Design Resilient Architectures (30%) #
This domain focuses on the ability to design architectures that are “self-healing” and highly available. In the SAA-C03 exam, the focus extends beyond simple redundancy to loose coupling and distributed data consistency. You must demonstrate how to use asynchronous messaging to isolate failures and select the right multi-AZ or multi-region strategies to meet strict RTO/RPO requirements.
-
Decoupling & Messaging:
-
Order Processing Guarantee - The Sequencing vs. Simplicity Trade-off
-
Decoupling Master-Worker Architectures - The Elasticity vs. Complexity Trade-off
-
Event-Driven Decoupling - The Pub/Sub vs. Stream Processing Trade-off
-
SaaS Integration Decoupling - The Operational Efficiency Trade-off
-
High-Throughput Message Ingestion - The Decoupling Trade-off Analysis
-
Storage & Availability:
-
Hybrid Storage Gateway - The Latency-Lifecycle Trade-off Analysis
-
Stateful Application Storage - The Shared State Trade-off Analysis
-
Global Data Ingestion to S3 - The Transfer Acceleration vs. Multi-Region Trade-off
-
Scalable File Storage for Variable Workloads - The Shared Storage Trade-off
-
Persistent Storage Migration - The Durability vs. Performance Trade-off
⚡ Domain 2: Design High-Performing Architectures (26%) #
Performance is about picking the “Right Tool for the Right Job.” This pillar evaluates your expertise in selecting compute, storage, and networking services that scale elastically. Key exam scenarios involve identifying bottlenecks in databases (Read-heavy vs. Write-heavy) and leveraging Edge Computing (CloudFront/Global Accelerator) to minimize global latency. You need to balance “Peak Performance” with “Architectural Complexity.”
-
Network & Content Delivery:
-
Multi-Region VoIP with Global Accelerator - The UDP Protocol Trade-off
-
Optimizing Static and Dynamic Content Delivery - The Performance-Cost Trade-off Analysis
-
Optimizing Global Static Website Delivery - The Cost-Latency Trade-off Analysis
-
Compute & Scaling:
-
Lambda Scalability & Database Coupling - The Decoupling Trade-off Analysis
-
Serverless Flash Sale Architecture - The Scalability-Cost Trade-off Analysis
-
IoT Telemetry Ingestion - The Serverless vs. Managed Infrastructure Trade-off
-
EC2 Capacity Reservation - The Flexibility vs. Commitment Trade-off
-
Database Scaling:
-
Read-Heavy Database Scaling - The High Availability Trade-off Analysis
-
RDS Storage Performance - The IOPS vs. Compute Trade-off Analysis
🔒 Domain 3: Design Secure Applications and Architectures (24%) #
Security is the top priority in any AWS environment. This domain tests the Principle of Least Privilege across Identity and Access Management (IAM), Data Encryption (at rest and in transit), and Network Security. SAA-C03 specifically emphasizes Hybrid Identity Federation (connecting on-premises AD to AWS) and advanced data protection techniques like S3 Object Lock and KMS cross-region key management.
-
Identity & Access Control:
-
Hybrid Identity Federation - The Trust Relationship Trade-off Analysis
-
Cross-Account S3 Access Control - FinOps & Operational Trade-off Analysis
-
Multi-Source Visualization - The Access Control Trade-off Analysis
-
Data & Network Security:
-
Database Credential Management - The Operational Overhead vs. Security Trade-off
-
Multi-Region Secrets Management - The Cost-Operational Trade-off Analysis
-
VPC Traffic Inspection - The Stateful Firewall vs. Monitoring Trade-off
-
VPC Endpoint for Private S3 Access - The Security-Cost Trade-off Analysis
-
S3 Data Protection - The Access Control vs. Data Integrity Trade-off
-
Secure Database Credential Management - The Security-Automation Trade-off
-
Multi-Region S3 Encryption with KMS - The Operational Simplicity Trade-off
-
DDoS Protection - The Service Selection and Cost-Tier Trade-off
💰 Domain 4: Design Cost-Optimized Architectures (20%) #
The final domain focuses on achieving business goals at the lowest price point. It’s not just about choosing the cheapest option, but about right-sizing resources and selecting the most efficient purchase models (Spot vs. Savings Plans). SAA-C03 expects you to master S3 Lifecycle policies for automated data tiering and use specialized governance tools like AWS Config to prevent “Shadow IT” and resource sprawl.
-
