Question 4

A Solutions Architect must build a highly available infrastructure for a popular global video game that runs on a mobile phone platform. The application runs on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Auto Scaling group across multiple Availability Zones. The database tier is an Amazon RDS MySQL Multi-AZ instance. The entire application stack is deployed in both us-east-1 and eu-central-1. Amazon Route 53 is used to route traffic to the two installations using a latency-based routing policy. A weighted routing policy is configured in Route 53 as a fail over to another region in case the installation in a region becomes unresponsive.

During the testing of disaster recovery scenarios, after blocking access to the Amazon RDS MySQL instance in eu-central-1 from all the application instances running in that region. Route 53 does not automatically failover all traffic to us-east-1.

Based on this situation, which changes would allow the infrastructure to failover to us-east-1? (Choose two.)

  • ○

    Specify a weight of 100 for the record pointing to the primary Application Load Balancer in us-east-1 and a weight of 60 for the pointing to the primary Application Load Balancer in eu-central-1.
  • ○

    Specify a weight of 100 for the record pointing to the primary Application Load Balancer in us-east-1 and a weight of 0 for the record pointing to the primary Application Load Balancer in eu-central-1.
  • ○

    Set the value of Evaluate Target Health to Yes on the latency alias resources for both eu-central-1 and us-east-1.
  • ○

    Write a URL in the application that performs a health check on the database layer. Add it as a health check within the weighted routing policy in both regions.
  • ○

    Disable any existing health checks for the resources in the policies and set a weight of 0 for the records pointing to primary in both eu-central-1 and us-east-1, and set a weight of 100 for the primary Application Load Balancer only in the region that has healthy resources.
Question 5

A company is running an application in the AWS Cloud. The company has several third-party services that integrate with the application through a RESTful API. The API is a serverless implementation with an Amazon API Gateway regional API endpoint that integrates with several different AWS Lambda functions.

The application's data is nonrelational and is stored in an Amazon DynamoDB table. The application and the API are running in the eu-west-1 Region. The company needs the API to also be available in the us-east-1 Region. All data must be available in both Regions. A solutions architect already has deployed all the Lambda functions in us-east-1

Which additional steps should the solutions architect take to meet these requirements? (Select TWO.)

Select all that apply, then click Submit answer.

  • ○

    Deploy a second API Gateway regional API endpoint in us-east-1. Create Lambda integration with the functions in us-east-1.
  • ○

    Enable DynamoDB Streams on the table in eu-west-1. Replicate all changes to a DynamoDB table in us-east-1
  • ○

    Modify the DynamoDB table to be a global table in eu-west-1 and in us-east-1.
  • ○

    Change the API Gateway API endpoint in eu-west-1 to an edge-optimized endpoint. Create Lambda integration with the functions in both Regions.
  • ○

    Create a DynamoDB read replica in us-east-1.
Question 6

You are the new IT architect in a company that operates a mobile sleep tracking application.

When activated at night, the mobile app is sending collected data points of 1 kilobyte every 5 minutes to your backend.

The backend takes care of authenticating the user and writing the data points into an Amazon DynamoDB table.

Every morning, you scan the table to extract and aggregate last night's data on a per user basis, and store the results in Amazon S3. Users are notified via Amazon SNS mobile push notifications that new data is available, which is parsed and visualized by the mobile app.

Currently you have around 100k users who are mostly based out of North America.

You have been tasked to optimize the architecture of the backend system to lower cost.

What would you recommend? (Choose two.)

Select all that apply, then click Submit answer.

  • ○

    Have the mobile app access Amazon DynamoDB directly Instead of JSON files stored on Amazon S3.
  • ○

    Write data directly into an Amazon Redshift cluster replacing both Amazon DynamoDB and Amazon S3.
  • ○

    Introduce an Amazon SQS queue to buffer writes to the Amazon DynamoDB table and reduce provisioned write throughput.
  • ○

    Introduce Amazon Elasticache to cache reads from the Amazon DynamoDB table and reduce provisioned read throughput.
  • ○

    Create a new Amazon DynamoDB table each day and drop the one for the previous day after its data is on Amazon S3.
