8.1.2. Tackling Scenario-Based Questions

First Principle: Scenario questions test your ability to synthesize knowledge across domains. The key is decomposing the scenario into its component requirements, then evaluating each answer against ALL requirements — not just the most obvious one.

Decomposition Framework:
  1. Identify the goal: What must the solution achieve? (security, compliance, cost, operational simplicity)
  2. Identify constraints: What limitations exist? (Regions, budget, existing architecture, compliance framework)
  3. Identify the security principle: Which first principle applies? (least privilege, defense-in-depth, zero trust, automation)
  4. Evaluate each answer against ALL requirements — the correct answer satisfies every constraint
Distractor Elimination Patterns:
Distractor TypeHow to Identify
Technically correct but operationally wrongWorks in theory but creates management overhead
Manual when automated exists"Manually configure" vs. "use AWS service"
Correct service, wrong featureUses S3 Glacier when S3 Object Lock was needed
Overkill solutionCloudHSM when KMS would suffice
Missing a requirementAddresses encryption but not access control
