AWS SAA-C03 practice, weighted like the real exam.

The question bank matches AWS's own domain weights. Five free questions a day, spaced repetition, full 65 question timed mock exam in Ultra. Scenarios use concrete services, not trivia.

§ Domain weights

Where the points actually live.

Design Secure Architectures (30%)

IAM roles vs users on EC2, SG-to-SG chaining, KMS customer-managed keys, S3 encryption options (SSE-S3, SSE-KMS, SSE-C), least privilege with tag conditions.

Design Resilient Architectures (26%)

Multi-AZ vs Read Replica, cross-Region replication, disaster recovery tier choice (backup and restore, pilot light, warm standby, multi-site), Route 53 failover.

Design High-Performing Architectures (24%)

Storage class selection (gp3 vs io2, EFS vs FSx for Windows vs FSx for Lustre), Auto Scaling, CloudFront, caching patterns.

Design Cost-Optimized Architectures (20%)

Spot vs Reserved vs Savings Plans vs On-Demand, S3 lifecycle policies, right-sizing, rearchitecting monoliths into serverless.

§ What trips most candidates

Common patterns that show up in our bank.

IAM: pick an IAM role for the workload, never long-lived access keys on an instance.
Networking: VPC endpoints (gateway for S3 and DynamoDB, interface for the rest) over NAT Gateway where possible.
Databases: RDS Multi-AZ is availability, Read Replica is read scaling; they are not interchangeable.
Storage: understand the practical difference between EFS (POSIX), FSx for Windows (SMB), and FSx for Lustre (HPC scratch).
Event routing: Kinesis Data Streams vs Kinesis Firehose vs SQS vs SNS vs EventBridge, each has a clear niche.
Cost: always check if the workload pattern (interruptible, steady, spiky) matches the pricing model.

Longer breakdown: AWS SAA-C03: where most people lose points.

§ Our approach

Daily habit, not a grind.

Cert Prep Platform delivers one question at a time through Telegram or the web app. Each question comes with an explanation that reasons about every option, not just a one-liner saying "correct". Missed items resurface via SM-2 spaced repetition, so you spend most of your time on the patterns you actually get wrong.

When you are ready for the exam, switch to the Mock Exam mode in Ultra. 65 questions, 130 minute timer, per-domain scorecard at the end. Sit it the weekend before your real exam and you will know if you are ready.
