A company manages its own Amazon EC2 instances that run MySQL databases. The company is manually managing replication and scaling as demand increases or decreases. The company needs a new solution that simplifies the process of adding or removing compute capacity to or from its database tier as needed. The solution also must offer improved performance, scaling, and durability with minimal effort from operations.

Which solution meets these requirements?

  1. Migrate the databases to Amazon Aurora Serverless for Aurora MySQL.
  2. Migrate the databases to Amazon Aurora Serverless for Aurora PostgreSQL.
  3. Combine the databases into one larger MySQL database. Run the larger database on larger EC2 instances.
  4. Create an EC2 Auto Scaling group for the database tier. Migrate the existing databases to the new environment.

Answer(s): A

What should the solutions architect recommend?

  1. Remove the two NAT instances and replace them with two NAT gateways in the same Availability Zone.
  2. Use Auto Scaling groups with Network Load Balancers for the NAT instances in different Availability Zones.
  3. Remove the two NAT instances and replace them with two NAT gateways in different Availability Zones.
  4. Replace the two NAT instances with Spot Instances in different Availability Zones and deploy a Network Load Balancer.

An application runs on an Amazon EC2 instance that has an Elastic IP address in VPC A. The application requires access to a database in VPC B. Both VPCs are in the same AWS account.

Which solution will provide the required access MOST securely?

  1. Create a DB instance security group that allows all traffic from the public IP address of the application server in VPC
  2. Configure a VPC peering connection between VPC A and VPC
  3. Make the DB instance publicly accessible. Assign a public IP address to the DB instance.
  4. Launch an EC2 instance with an Elastic IP address into VPC B. Proxy all requests through the new EC2 instance.

Answer(s): B



A company runs demonstration environments for its customers on Amazon EC2 instances. Each environment is isolated in its own VPC. The company’s operations team needs to be notified when RDP or SSH access to an environment has been established.

What should a solutions architect recommend to meet these requirements?

  1. Configure Amazon CloudWatch Application Insights to create AWS Systems Manager OpsItems when RDP or SSH access is detected.
  2. Configure the EC2 instances with an IAM instance profile that has an IAM role with the AmazonSSMManagedInstanceCore policy attached.
  3. Publish VPC flow logs to Amazon CloudWatch Logs. Create required metric filters. Create an Amazon CloudWatch metric alarm with a notification action for when the alarm is in the ALARM state.
  4. Configure an Amazon EventBridge rule to listen for events of type EC2 Instance State-change Notification. Configure an Amazon Simple Notification Service (Amazon SNS) topic as a target. Subscribe the operations team to the topic.

Answer(s): C
