Design Secure Architectures
Use this page to practise secure architecture questions. The most common mistake is confusing the responsibility boundary — know which security controls AWS manages and which are your responsibility.
📅 Day 49🎯 ~25 questions/day⚖ 30% of exam- ✓IAM policies: identity-based, resource-based, permission boundaries.
- ✓VPC security: security groups vs NACLs, route tables, VPC endpoints.
- ✓Encryption: KMS, SSE-S3, SSE-KMS, client-side encryption.

Design Resilient Architectures
Use this page to practise high availability and resilience questions. The SAA-C03 exam tests your ability to match an architecture pattern to an RTO/RPO requirement — know the cost and recovery time of each pattern.
📅 Day 49🎯 ~23 questions/day⚖ 26% of exam- ✓Multi-AZ vs multi-Region deployment trade-offs.
- ✓Auto Scaling policies and when to scale horizontally vs vertically.
- ✓Elastic Load Balancing: ALB, NLB, CLB and their use cases.

Design High-Performing Architectures
Design High-Performing Architectures is 24% of SAA-C03 and tests whether you can pick AWS services and configurations that meet latency, throughput, and scaling goals without over-provisioning. Expect scenario questions comparing instance families, storage types, caching layers, database engines, and network paths, then asking which choice best satisfies a stated performance requirement at the lowest cost.
📅 Day 49🎯 ~23 questions/day⚖ 24% of exam- ✓Selecting EC2 instance families, burstable vs fixed performance, and placement groups for compute workloads
- ✓Choosing EBS volume types (gp3, io2, st1) and S3 storage classes or transfer acceleration for throughput
- ✓Deciding between ElastiCache Redis/Memcached, CloudFront, and Global Accelerator for latency reduction

Design Cost-Optimized Architectures
Design Cost-Optimized Architectures is 20% of SAA-C03 and tests whether you can pick the cheapest AWS design that still meets availability, performance, and durability requirements. Expect scenario questions on S3 storage classes and lifecycle rules, EC2 purchasing options, EBS volume types, RDS/Aurora choices, data transfer costs, and right-sizing versus elasticity trade-offs.
📅 Day 49🎯 ~24 questions/day⚖ 20% of exam- ✓Selecting EC2 purchasing options: On-Demand, Reserved, Savings Plans, Spot, and Dedicated Hosts
- ✓Choosing S3 storage classes and lifecycle transitions, including Intelligent-Tiering and Glacier tiers
- ✓Matching EBS volume types (gp3, io2, st1, sc1) and snapshot costs to workload needs
