2. The 6-Week Study Plan (Proven Strategy)
Based on feedback from thousands of successful candidates, here's a realistic 6-week study plan requiring 10-15 hours per week:
Week 1-2: Core AWS Services
Focus on understanding the fundamentals:
- EC2: Instance types, pricing models, Auto Scaling, Load Balancers
- S3: Storage classes, encryption, versioning, lifecycle policies
- VPC: Subnets, route tables, Internet Gateways, NAT Gateways, Security Groups, NACLs
- IAM: Users, groups, roles, policies, least privilege principle
Week 3-4: Advanced Services
- Databases: RDS, DynamoDB, ElastiCache, Aurora
- High Availability: Multi-AZ, Read Replicas, CloudFront
- Monitoring: CloudWatch, CloudTrail, AWS Config
- Security: KMS, WAF, Shield, Secrets Manager
Week 5: Practice & Review
- Take 3-4 full-length practice tests
- Review every wrong answer - understand WHY you got it wrong
- Focus on weak domains identified in practice tests
- Create flash cards for services you confuse
Week 6: Final Sprint
- Take 2 more practice tests (aim for 80%+ score)
- Review AWS Well-Architected Framework
- Watch AWS re:Invent videos on key services
- Schedule your exam for end of week 6
3. Best Study Resources (Free & Paid)
🆓 Free Resources:
- AWS Documentation - The ultimate reference (boring but comprehensive)
- AWS Free Tier - Get hands-on experience without spending money
- CertifyPro Practice Tests - Realistic questions with detailed explanations
- AWS Skill Builder - Official training videos from AWS
💰 Worth Paying For:

4. Master the 4 Exam Domains
Domain 1: Design Secure Architectures (30%)
Key Topics:
- IAM best practices, roles vs users, policy evaluation logic
- VPC security: Security Groups vs NACLs, private vs public subnets
- Encryption: S3 encryption (SSE-S3, SSE-KMS), EBS encryption, RDS encryption
- Network security: WAF, Shield, Security Hub
💡 Pro Tip:
Always choose the option with least privilege. If a question involves encryption and control over keys, SSE-KMS is usually the answer.
Domain 2: Design Resilient Architectures (26%)
Key Topics:
- Multi-AZ deployments, Auto Scaling, Load Balancers (ALB vs NLB)
- S3 cross-region replication, versioning, lifecycle policies
- RDS Multi-AZ, Read Replicas, automated backups
- Decoupling: SQS, SNS, EventBridge, Step Functions
💡 Pro Tip:
Availability Zones protect against datacenter failures. Regions protect against regional disasters. Choose based on the scenario's requirements.
Domain 3: Design High-Performing Architectures (24%)
Key Topics:
- CloudFront for content delivery, S3 Transfer Acceleration
- ElastiCache (Redis vs Memcached) for caching strategies
- Database performance: DynamoDB DAX, RDS read replicas, Aurora
- EBS volume types: gp3, io2, st1, sc1 use cases
💡 Pro Tip:
CloudFront is almost always the answer for "global users" scenarios. ElastiCache is the answer for session storage and database caching.
Domain 4: Design Cost-Optimized Architectures (20%)
Key Topics:
- EC2 pricing: On-Demand, Reserved, Spot, Savings Plans
- S3 storage classes: Standard, IA, One Zone-IA, Glacier, Glacier Deep Archive
- Cost monitoring: Cost Explorer, Budgets, Billing Alarms
- Right-sizing: Auto Scaling, Lambda for variable workloads
💡 Pro Tip:
Spot Instances = up to 90% savings but can be interrupted. Reserved Instances = predictable, long-term workloads. Learn when to use each.
5. Practice Tests Strategy (Critical!)
Practice tests are the most important part of your preparation. Here's how to use them effectively:
⚠️ Common Mistake to Avoid:
Don't memorize answers! Understand the WHY behind each correct answer. Exam questions will be worded differently but test the same concepts.
Start with CertifyPro Free Tests
Take our free practice tests to establish a baseline. Focus on understanding the detailed explanations for every question.
Review Wrong Answers Immediately
After each test, spend 2x the time reviewing wrong answers. Create flashcards for concepts you missed.
Simulate Exam Conditions
Take at least 2 full-length tests in one sitting with a 130-minute timer. No breaks, no phones, no distractions.
Track Your Progress
Keep a spreadsheet of your scores by domain. This shows which areas need more study.
🎯 When Are You Ready?
You're ready to take the real exam when you consistently score 80%+ on practice tests and can explain why each wrong answer is incorrect.
6. Exam Day Tips
⏰ Time Management:
- You have 130 minutes for 65 questions = 2 minutes per question
- Flag difficult questions and come back to them. Don't waste 5 minutes on one question.
- Aim to finish with 20 minutes remaining to review flagged questions
🧠 Answering Strategies:
- Read carefully: AWS questions have specific wording. "Most cost-effective" vs "most performant" lead to different answers.
- Eliminate wrong answers: Often 2 answers are obviously wrong. Choose between the remaining 2.
- AWS-native solutions: AWS prefers its own services. Choose AWS KMS over third-party encryption, for example.
- Managed services win: Lambda beats EC2, RDS beats self-managed database, etc.
