A company is launching an application on AWS. The application uses an Application Load Balancer (ALB) to direct traffic to at least two Amazon EC2 instances in a single target group. The instances are in an Auto Scaling group for each environment. The company requires a development environment and a production environment. The production environment will have periods of high traffic.
Which solution will configure the development environment MOST cost-effectively?

  1. Reconfigure the target group in the development environment to have only one EC2 instance as a target.
  2. Change the ALB balancing algorithm to least outstanding requests.
  3. Reduce the size of the EC2 instances in both environments.
  4. Reduce the maximum number of EC2 instances in the development environment’s Auto Scaling group.

Answer(s): D



A company runs a web application on Amazon EC2 instances in multiple Availability Zones. The EC2 instances are in private subnets. A solutions architect implements an internet-facing Application Load Balancer (ALB) and specifies the EC2 instances as the target group. However, the internet traffic is not reaching the EC2 instances.
How should the solutions architect reconfigure the architecture to resolve this issue?

  1. Replace the ALB with a Network Load Balancer. Configure a NAT gateway in a public subnet to allow internet traffic.
  2. Move the EC2 instances to public subnets. Add a rule to the EC2 instances’ security groups to allow outbound traffic to 0.0.0.0/0.
  3. Update the route tables for the EC2 instances’ subnets to send 0.0.0.0/0 traffic through the internet gateway route. Add a rule to the EC2 instances’ security groups to allow outbound traffic to 0.0.0.0/0.
  4. Create public subnets in each Availability Zone. Associate the public subnets with the ALB. Update the route tables for the public subnets with a route to the private subnets.

Answer(s): D



A company has deployed a database in Amazon RDS for MySQL. Due to increased transactions, the database support team is reporting slow reads against the DB instance and recommends adding a read replica.
Which combination of actions should a solutions architect take before implementing this change? (Choose two.)

  1. Enable binlog replication on the RDS primary node.
  2. Choose a failover priority for the source DB instance.
  3. Allow long-running transactions to complete on the source DB instance.
  4. Create a global table and specify the AWS Regions where the table will be available.
  5. Enable automatic backups on the source instance by setting the backup retention period to a value other than 0.

Answer(s): C,E



A company runs analytics software on Amazon EC2 instances. The software accepts job requests from users to process data that has been uploaded to Amazon S3. Users report that some submitted data is not being processed Amazon CloudWatch reveals that the EC2 instances have a consistent CPU utilization at or near 100%. The company wants to improve system performance and scale the system based on user load.
What should a solutions architect do to meet these requirements?

  1. Create a copy of the instance. Place all instances behind an Application Load Balancer.
  2. Create an S3 VPC endpoint for Amazon S3. Update the software to reference the endpoint.
  3. Stop the EC2 instances. Modify the instance type to one with a more powerful CPU and more memory. Restart the instances.
  4. Route incoming requests to Amazon Simple Queue Service (Amazon SQS). Configure an EC2 Auto Scaling group based on queue size. Update the software to read from the queue.

Answer(s): D
