Question 3:
A company is creating a new web application for its subscribers. The application will consist of a static single page and a persistent database layer. The application will have millions of users for 4 hours in the morning, but the application will have only a few thousand users during the rest of the day. The company\’s data architects have requested the ability to rapidly evolve their schema.
Which solutions will meet these requirements and provide the MOST scalability? (Choose two.)
A. Deploy Amazon DynamoDB as the database solution. Provision on-demand capacity.
B. Deploy Amazon Aurora as the database solution. Choose the serverless DB engine mode.
C. Deploy Amazon DynamoDB as the database solution. Ensure that DynamoDB auto scaling is enabled.
D. Deploy the static content into an Amazon S3 bucket. Provision an Amazon CloudFront distribution with the S3 bucket as the origin.
E. Deploy the web servers for static content across a fleet of Amazon EC2 instances in Auto Scaling groups. Configure the instances to periodically refresh the content from an Amazon Elastic File System (Amazon EFS) volume.
Correct Answer: AD
Remember for Provisioned with Auto-Scaling you are basically paying for throughput 24/7. Whereas for On-Demand Scaling you pay per request. This means for applications still in development or low traffic applications, it might be more economical to use On-Demand Scaling and not worry about provisioning throughput. However, at scale, this can quickly shift once you have a more consistent usage pattern. https://dynobase.dev/dynamodb-on-demand-vs-provisionedscaling/

The customers are distributed across North America and Europe The company wants to reduce the cost that is associated with data transfers and wants to maintain or improve performance.
What should a solutions architect do to meet these requirements?
A. Configure S3 Transfer Acceleration on the existing S3 bucket Direct customer requests to the S3 Transfer Acceleration endpoint Continue to use S3 signed URLs for access control
B. Deploy an Amazon CloudFront distribution with the existing S3 bucket as the origin Direct customer requests to the CloudFront URL Switch to CloudFront signed URLs for access control
C. Set up a second S3 bucket in the eu-central-1 Region with S3 Cross-Region Replication between the buckets Direct customer requests to the closest Region Continue to use S3 signed URLs for access control
D. Modify the web application to enable streaming of the datasets to end users. Configure the web application to read the data from the existing S3 bucket Implement access control directly in the application
Correct Answer: B
To reduce the cost associated with data transfers and maintain or improve performance, a solutions architect should use Amazon CloudFront, a content delivery network (CDN) service that securely delivers data, videos, applications, and
APIs to customers globally with low latency and high transfer speeds.
Deploying a CloudFront distribution with the existing S3 bucket as the origin will allow the company to serve the data to customers from edge locations that are closer to them, reducing data transfer costs and improving performance.
Directing customer requests to the CloudFront URL and switching to CloudFront signed URLs for access control will enable customers to access the data securely and efficiently.
