Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 153 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 153
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company has deployed an application on AWS Elastic Beanstalk. The application uses Amazon Aurora for the database layer. An Amazon CloudFront distribution serves web requests and includes the Elastic Beanstalk domain name as the origin server. The distribution is configured with an alternate domain name that visitors use when they access the application.

Each week, the company takes the application out of service for routine maintenance. During the time that the application is unavailable, the company wants visitors to receive an informational message instead of a CloudFront error message.

A solutions architect creates an Amazon S3 bucket as the first step in the process.

Which combination of steps should the solutions architect take next to meet the requirements? (Choose three.)

  • A. Upload static informational content to the S3 bucket.
  • B. Create a new CloudFront distribution. Set the S3 bucket as the origin.
  • C. Set the S3 bucket as a second origin in the original CloudFront distribution. Configure the distribution and the S3 bucket to use an origin access identity (OAI).
  • D. During the weekly maintenance, edit the default cache behavior to use the S3 origin. Revert the change when the maintenance is complete.
  • E. During the weekly maintenance, create a cache behavior for the S3 origin on the new distribution. Set the path pattern to \ Set the precedence to 0. Delete the cache behavior when the maintenance is complete.
  • F. During the weekly maintenance, configure Elastic Beanstalk to serve traffic from the S3 bucket.

A. Upload static informational content to the S3 bucket. C. Set the S3 bucket as a second origin in the original CloudFront distribution. Configure the distribution and the S3 bucket to use an origin access identity (OAI). D. During the weekly maintenance, edit the default cache behavior to use the S3 origin. Revert the change when the maintenance is complete. Step 1: The solutions architect should upload static informational content to the S3 bucket, this content will be shown to the users when the application is down for maintenance. Step 2: The solutions architect should set the S3 bucket as a second origin in the original CloudFront distribution. To keep the S3 bucket secure, the solutions architect should configure the distribution and the S3 bucket to use an origin access identity (OAI). This will ensure that only CloudFront has access to the S3 bucket.

Step 3: During the weekly maintenance, the solutions architect should edit the default cache behavior of the CloudFront distribution to use the S3 origin. This will redirect all incoming traffic to the S3 bucket and show the static informational content to the users. Once the maintenance is complete, the solutions architect should revert the change back to the original Elastic Beanstalk origin. Option B: Creating a new CloudFront distribution and setting the S3 bucket as the origin is unnecessary and could cause confusion for the users. Option E: During the weekly maintenance, creating a cache behavior for the S3 origin on the new distribution is unnecessary, it is more complex and prone to human error. Option F: Configuring Elastic Beanstalk to serve traffic from the S3 bucket is not necessary because CloudFront is already being used as the web request server.

From the given options ACD makes the most sense. In real life the CloudFront feature to show custom error responses might make a lot more sense: https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/GeneratingCustomErrorResponses.html#custom-error-pages-procedure This would avoid the manual steps and by that is less prone to human errors.
