A web application runs on Amazon EC2 instances behind an ELB Application Load Balancer. The instances run in an EC2 Auto Scaling group across multiple Availability Zones. Amazon Route 53 is used for DNS and points to the load balancer. A SysOps Administrator has launched a new Auto Scaling group with a new version of the application, and wants to gradually shift traffic to the new version.
How can this be accomplished?

• A.Create an Auto Scaling target tracking scaling policy to gradually move traffic from the old version to the new one
• B.Change the Application Load Balancer to a Network Load Balancer, then add both Auto Scaling groups as targets
• C.Use an Amazon Route 53 weighted routing policy to gradually move traffic from the old version to the new one
• D.Deploy Amazon Redshift to gradually move traffic from the old version to the new one using a set of predefined values

What are the MOST likely reasons for this situation? (Select TWO.)

• A.The Administrator must configure the VPC Flow Logs to have them sent to AWS CloudTrail.
• B.The Administrator has waited less than ten minutes for the log group to be created in CloudWatch.

A sysops administrator is managing a VPC network consisting of public and private subnets. Instances in the private subnets access the Internet through a NAT gateway. A recent AWS bill shows that the NAT gateway charges have doubled. The administrator wants to identify which instances are creating the most network traffic.
How should this be accomplished?

• A.Enable flow logs on the NAT gateway elastic network interface and use Amazon CloudWatch insights to filter data based on the source IP addresses.
• B.Run an AWS Cost and Usage report and group the findings by instance ID.
• C.Use the VPC traffic mirroring feature to send traffic to Amazon QuickSight.
• D.Use Amazon CloudWatch metrics generated by the NAT gateway for each individual instance.
