Essential Hands-On Labs
Theory alone won't cut it. The exam tests practical knowledge, so get your hands dirty with these essential labs. Each lab should take 30-60 minutes.
Must-Do Labs (Complete All)
Multi-Tier Web Application
Deploy a 3-tier app with EC2, RDS, and Load Balancer. Practice Auto Scaling.
VPC with Public/Private Subnets
Create custom VPC, configure NAT Gateway, and test connectivity.
S3 Static Website with CloudFront
Host a static site, configure caching, and set up custom domain.
RDS Multi-AZ with Read Replica
Set up database redundancy and test failover scenarios.
Pro tip: Document each lab in your own words. The act of explaining what you did reinforces learning and helps during exam review.
Recommended Resources
Quality resources save time and improve retention. Here are battle-tested recommendations based on what actually helps students pass.
Official AWS Resources
• AWS Well-Architected Framework (free)
• AWS Architecture Center case studies

- • Look for keywords like "most cost-effective" or "least operational overhead"
Common Traps to Avoid
- • Don't overthink simple scenarios
- • AWS prefers managed services over custom solutions
- • Multi-AZ vs Multi-Region confusion
- • Security Group vs NACL differences
Final Thoughts
The AWS Solutions Architect Associate certification opens doors to incredible opportunities. Career transformations often happen within months of earning this credential.
Remember, this exam tests your ability to design architectures, not memorize service features. Focus on understanding the "why" behind architectural decisions, and you'll find the exam much more manageable.
