A company uses a popular content management system (CMS) for its corporate website. However, the required patching and maintenance are burdensome. The company is redesigning its website and wants a new solution. The website will be updated four times a year and does not need to have any dynamic content available. The solution must provide high scalability and enhanced security. Which combination of changes will meet these requirements with the LEAST operational overhead? (Choose two.)

UAnonymous
A
Configure Amazon CloudFront in front of the website to use HTTPS functionality.
B
Deploy an AWS WAF web ACL in front of the website to provide HTTPS functionality.
C
Create and deploy an AWS Lambda function to manage and serve the website content.
D
Create the new website and an Amazon S3 bucket. Deploy the website on the S3 bucket with static website hosting enabled.
E
Create the new website. Deploy the website by using an Auto Scaling group of Amazon EC2 instances behind an Application Load Balancer.

Explanation
Correct Answers: D and A
Why D (Amazon S3 with static website hosting) is correct:
- The website only needs updates 4 times per year and has no dynamic content requirements, making it ideal for a static website.
- Amazon S3 static website hosting provides a serverless, highly scalable solution with minimal operational overhead.
- No patching or maintenance is required for S3 - AWS manages the infrastructure.
- S3 provides built-in durability and availability.
- This eliminates the burden of patching and maintenance mentioned in the problem.
Why A (Amazon CloudFront with HTTPS) is correct:
- CloudFront provides HTTPS functionality for secure content delivery.
- It enhances security by providing SSL/TLS encryption for data in transit.
- CloudFront improves performance through edge caching and provides DDoS protection.
- Combined with S3, this creates a highly scalable, secure, and low-maintenance solution.
Why other options are incorrect:
B (AWS WAF for HTTPS): AWS WAF is a web application firewall, not a mechanism for providing HTTPS functionality. HTTPS is provided by CloudFront, ALB, or other services, not WAF.
C (Lambda function): While Lambda can serve static content, it's more complex than S3 static hosting for this use case. Lambda would require code management and potentially more operational overhead than S3.
E (Auto Scaling group of EC2 instances): This would reintroduce the patching and maintenance burden the company wants to avoid. EC2 instances require OS patching, security updates, and infrastructure management.
Key Points:
- The requirement for "LEAST operational overhead" points to serverless solutions.
- Static content with infrequent updates is perfect for S3 + CloudFront.
- This architecture provides high scalability (S3 scales automatically) and enhanced security (CloudFront with HTTPS, DDoS protection).
- The solution eliminates server management, patching, and maintenance tasks.
