Which approach balances cost and performance for a workload that has predictable baseline traffic with occasional spikes?

Provision resources for peak capacity

Use a fixed number of instances regardless of load

Use auto scaling to match capacity to demand

Always use the largest instance type

A company has a large amount of data stored in Amazon S3 that is frequently accessed by EC2 instances in the same VPC. The company is seeing high data transfer charges for traffic between the EC2 instances and S3. Which solution would reduce these data transfer costs?

Enable S3 Transfer Acceleration on the bucket.

Use a NAT gateway to route traffic to S3.

Create a gateway VPC endpoint for S3 and route traffic through it.

Move the EC2 instances to a different Availability Zone.

Which AWS feature allows an EC2 instance to maintain a consistent public IP address even if the instance is stopped and started?

Elastic Network Interface (ENI)
