Pre-Exam Preparation

Day Before:

• Confirm exam time and location
• Prepare two forms of ID
• Get good sleep

Exam Day:

• Arrive 30 minutes early
• Don't cram at the last minute
• Stay calm

Exam Strategies

1. Time Management

• 130 minutes for 65 questions = average 2 minutes/question
• Mark uncertain questions, come back later

2. Process of Elimination

• First eliminate obviously wrong options
• Usually can eliminate 1-2 options

3. Watch for Keywords

• "Most cost-effective" → Consider Spot, Reserved
• "Highest availability" → Multi-AZ, Multi-Region
• "Fastest" → CloudFront, ElastiCache
• "Serverless" → Lambda, DynamoDB, S3

4. Scenario Question Approach

1. Read requirements first (last sentence usually key)
2. Identify constraints
3. Eliminate non-compliant options
4. Choose best answer (not necessarily perfect, but most suitable)

Common Traps

1. Over-Engineering

• If question asks for simple, don't choose complex solutions
• Read requirements scope carefully

2. Confusing Similar Services

• SQS vs SNS
• EBS vs EFS vs S3
• ALB vs NLB

3. Ignoring Cost Factors

• If question doesn't say unlimited budget, consider cost
• "Most cost-effective" is a keyword

Success Stories

Story 1: Zero Background, Passed in 8 Weeks

Background: Non-IT PM wanting to transition to cloud Preparation Time: 8 weeks, 1-2 hours daily Score: 782/1000

Experience: I had no technical background; couldn't understand EC2, VPC at first. Then found Stephane's course explained clearly, and with hands-on practice I gradually understood.

Most helpful was Tutorials Dojo question bank. After 500 questions, I had very clear understanding of exam scope. Must understand wrong answers—I noted the reason for each mistake.

Advice: Don't just watch courses, must do hands-on. AWS Free Tier is sufficient for practice.

Story 2: 4-Week Intensive Preparation

Background: 3-year backend engineer, used AWS before Preparation Time: 4 weeks, 3 hours daily Score: 856/1000

Experience: Since I used AWS at work, I'd touched many services, so preparation time was shorter. But there were still many details I hadn't noticed at work, like various pricing models, disaster recovery strategies.

I focused on practice exams, did about 800 questions. After each practice exam, spent 2-3 hours reviewing wrong answers, looking up documentation to fill knowledge gaps.

Advice: Experienced people can skip basic courses, go straight to questions to find weaknesses.

Story 3: Passed on Second Attempt

Background: Cloud beginner First Attempt: 680/1000 (failed) Second Attempt: 745/1000 (passed)

Experience: First time I was overconfident, only did 200 questions before taking exam, failed by 40 points. Main failures were in security and networking sections.

Second time spent 3 weeks specifically strengthening weaknesses, understood IAM Policy and VPC architecture clearly, did another 300 practice exam questions.

Advice: Practice exams should be stable at 80%+ before taking real exam. Don't save on exam fees by being underprepared.
