Exam AWS Certified Solutions Architect - Professional topic 1 question 959 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 959
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A company is using a single AWS Region for its ecommerce website. The website includes a web application that runs on several Amazon EC2 instances behind an Application Load Balancer (ALB). The website also includes an Amazon DynamoDB table. A custom domain name in Amazon Route 53 is linked to the ALB. The company created an SSL/TLS certificate in AWS Certificate Manager (ACM) and attached the certificate to the ALB. The company is not using a content delivery network as part of its design.

The company wants to replicate its entire application stack in a second Region to provide disaster recovery, plan for future growth, and provide improved access time to users. A solutions architect needs to implement a solution that achieves these goals and minimizes administrative overhead.

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

  • A. Create an AWS CloudFormation template for the current infrastructure design. Use parameters for important system values, including Region. Use the CloudFormation template to create the new infrastructure in the second Region.
  • B. Use the AWS Management Console to document the existing infrastructure design in the first Region and to create the new infrastructure in the second Region.
  • C. Update the Route 53 hosted zone record for the application to use weighted routing. Send 50% of the traffic to the ALB in each Region.
  • D. Update the Route 53 hosted zone record for the application to use latency-based routing. Send traffic to the ALB in each Region.
  • E. Update the configuration of the existing DynamoDB table by enabling DynamoDB Streams. Add the second Region to create a global table.
  • F. Create a new DynamoDB table. Enable DynamoDB Streams for the new table. Add the second Region to create a global table. Copy the data from the existing DynamoDB table to the new table as a one-time operation.

E is right and F is wrong. "Starting today, you can convert your existing DynamoDB tables to global tables with a few clicks in the AWS Management Console, or using the AWS Command Line Interface (AWS CLI), or the Amazon DynamoDB API.

Selected Answer: ADF
I go with ADF for A: AWS CloudFormation simplifies provisioning and management on AWS. You can create templates for application or service architectures and instruct AWS CloudFormation to use those templates to quickly and reliably provision services or applications (known as "stacks"). You can also update or replicate stacks very easily if needed. https://aws.amazon.com/cloudformation/resources/templates/ for D : - and provide improved access time to users Latency routing policy – Use the latency routing policy when you have resources in multiple AWS Regions and want to route traffic to the Region that provides the best latency. You can use latency routing to create records in a private hosted zone. https://docs.aws.amazon.com/fr_fr/Route53/latest/DeveloperGuide/routing-policy.html

For F: Previously, only empty tables could be converted to global tables. You had to guess your regional usage of a table at the time you created it. Now you can go global, or you can extend existing global tables to additional regions at any time. Your applications can continue to use the table while we set up the replication. When you add a region to your table, DynamoDB begins populating the new replica using a snapshot of your existing table. Your applications can continue writing to your existing region while DynamoDB builds the new replica, and all in-flight updates will be eventually replicated to your new replica. https://aws.amazon.com/fr/blogs/aws/new-convert-your-single-region-amazon-dynamodb-tables-to-global-tables/
