Question #849

Which option represents a shared responsibility between AWS and its customers under the AWS shared responsibility model?

A

Configuration of RDS database parameters

B

Edge location management for CloudFront

C

DDoS mitigation measures

D

Hardware maintenance of data centers

Explanation

In the AWS shared responsibility model:

- C (DDoS mitigation) is correct because AWS handles basic protections (e.g., AWS Shield Standard for DDoS mitigation at the infrastructure level), while customers are responsible for application-layer protections (e.g., using AWS WAF or Shield Advanced).

- A (RDS configuration) is incorrect because configuring database parameters (e.g., security groups, backups) is solely the customer's responsibility.
- B (CloudFront edge locations) is incorrect because AWS fully manages edge location infrastructure and maintenance.
- D (Data center hardware) is incorrect because AWS is fully responsible for physical infrastructure maintenance.

Key Points: AWS manages security of the cloud (infrastructure), while customers manage security in the cloud (data, applications). DDoS mitigation is a shared layer where AWS provides foundational protections, and customers enhance them.

Answer

The correct answer is: C
