Q77 — AWS DVA-C02 Ch.2

Question 77 of 100 | ← Chapter 2

What is the execution order of hooks for in-place deployments using AWS CodeDeploy?

• A. BeforeInstall -> ApplicationStop -> ApplicationStart -> AfterInstall
• B. ApplicationStop -> BeforeInstall -> AfterInstall -> ApplicationStart ✓
• C. BeforeInstall -> ApplicationStop -> ValidateService -> ApplicationStart
• D. ApplicationStop -> BeforeInstall -> ValidateService -> ApplicationStart

Correct Answer: B. ApplicationStop -> BeforeInstall -> AfterInstall -> ApplicationStart

Explanation

For in-place deployments, AWS CodeDeploy executes hooks in the following strict sequence: ApplicationStop (stops the application), BeforeInstall (runs before installing new artifacts), AfterInstall (runs after installation completes), and finally ApplicationStart (restarts the application). ValidateService is not a standard CodeDeploy hook for in-place deployments. Therefore, Option B is correct.
