Question 144

A company plans to use Amazon ElastiCache for its multi-tier web application. A solutions architect creates a Cache VPC for the ElastiCache cluster and an App VPC for the application’s Amazon EC2 instances. Both VPCs are in the us-east-1 Region.

The solutions architect must implement a solution to provide the application’s EC2 instances with access to the ElastiCache cluster.

Which solution will meet these requirements MOST cost-effectively?

Options:

Create a peering connection between the VPCs. Add a route table entry for the peering connection in both VPCs. Configure an inbound rule for the ElastiCache cluster’s security group to allow inbound connection from the application’s security group.

Create a Transit VPC. Update the VPC route tables in the Cache VPC and the App VPC to route traffic through the Transit VPC. Configure an inbound rule for the ElastiCache cluster's security group to allow inbound connection from the application’s security group.

Create a peering connection between the VPCs. Add a route table entry for the peering connection in both VPCs. Configure an inbound rule for the peering connection’s security group to allow inbound connection from the application’s security group.

The company wants to have separate deployments of its web platform across multiple Regions. However the company must maintain a single primary reservation database that is globally consistent.

Convert the application to use Amazon DynamoDB. Use a global table for the center reservation table. Use the correct Regional endpoint in each Regional deployment.

Migrate the database to an Amazon Aurora MySQL database. Deploy Aurora Read Replicas in each Region. Use the correct Regional endpoint in each Regional deployment for access to the database.

Migrate the database to an Amazon RDS for MySQL database Deploy MySQL read replicas in each Region. Use the correct Regional endpoint in each Regional deployment for access to the database.
