AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 244

You have deployed a website that utilizes CloudFront, Elastic Loadbalancer, and S3 to serve content. When users access your site, they receive a "mixed content" security warning.
What is most likely the problem?

Answer options

• A. There is no rule in your bucket policy allowing public access.
• B. You have applied your SSL to your Elastic Loadbalancer but not your CDN.
• C. Your S3 Bucket permissions are incorrect.
• D. You are using an SSL from an external CA.

Correct answer: B

Explanation

The correct answer is B because if the CDN (CloudFront) does not have SSL configured, it can serve content over HTTP, leading to a 'mixed content' warning when HTTPS is used. Options A and C are related to access and permissions but do not directly address the mixed content issue. Option D, while potentially a concern, does not specifically relate to the mixed content warning in this context.
