A company's application is running on Amazon EC2 instances within an Auto Scaling group behind an Elastic Load Balancer. Based on the application's history the company anticipates a spike in traffic during a holiday each year. A solutions architect must design a strategy to ensure that the Auto Scaling group proactively increases capacity to minimize any performance impact on application users.
Which solution will meet these requirements?

• A.Increase the minimum and maximum number of EC2 instances in the Auto Scaling group during the peak demand period.
• B.Configure an Amazon Simple Notification Service (Amazon SNS) notification to send alerts when there are autoscaling EC2_INSTANCE_LAUNCH events.
• C.Create an Amazon CloudWatch alarm to scale up the EC2 instances when CPU utilization exceeds 90%.
• D.Create a recurring scheduled action to scale up the Auto Scaling group before the expected period of peak demand.

A company has two VPCs that are located in the us-west-2 Region within the same AWS account. The company needs to allow network traffic between these VPCs. Approximately 500 GB of data transfer will occur between the VPCs each month.
What is the MOST cost-effective solution to connect these VPCs'?'

• A.Set up a 1 GB AWS Direct Connect connection between the VPCs. Update the route tables of each VPC to use the Direct Connect connection for inter-VPC communication.
• B.Set up a VPC peering connection between the VPCs. Update the route tables of each VPC to use the VPC peering connection for inter-VPC communication.
• C.Implement AWS Transit Gateway to connect the VPCs Update the route tables of each VPC to use the transit gateway for inter-VPC communication
• D.Implement an AWS Site-to-Stte VPN tunnel between the VPCs. Update the route tables of each VPC to use the VPN tunnel for inter-VPC communication
