Practice Design Cost-Optimized Architectures questionsHow to Use Domain Weights in Your Study Plan
The heaviest domain on the SAA-C03 is "Design Secure Architectures" at 30%. Start here and return to it regularly.
Allocate study time proportional to domain weight — a 25% domain deserves roughly 25% of your prep hours.
Never skip a low-weight domain. A 10% domain still represents 5–7 exam questions — enough to make the difference between pass and fail.
Use JT Exams domain analytics to track your accuracy per domain automatically. The system routes extra questions to your weak areas.

SAA-C03 Concept Guides
S3 Storage Classes
S3 looks like a simple file store until you see the bill.
AWS IAM
In AWS, every action against every resource is an API call, and every API call must be authorized.
AWS VPC
Your resources in AWS do not automatically sit in a protected private network.
EC2 Purchasing Options
Running an EC2 instance on-demand for a year costs significantly more than committing to that same instance in advance.
AWS High Availability
High availability and fault tolerance are not the same thing, and the SAA-C03 exam expects you to know the difference.
IaaS, PaaS, SaaS
Before you can architect a cloud solution or answer a security question about cloud responsibility, you need to understand what cloud service models are and what they actually change about who manages what.
