Q87 Multiple choice

A company hosts an internal web application on a single Amazon EC2 instance in a private subnet. The company is running NAT software on an EC2 instance for outbound internet access from the application. To improve fault tolerance and help ensure high availability, the company needs a more resilient architecture for both the application and its outbound connectivity.

Which combination of actions will meet these requirements? (Select TWO.)

Select all that apply.

A
Launch a standby NAT instance in a different Availability Zone. Update the route tables if the primary instance becomes unavailable.
B
Attach a Network Load Balancer in front of the web application. Configure Amazon CloudWatch alarms to attempt to recover the instance.
C
Deploy EC2 instances in an Auto Scaling group across multiple Availability Zones. Place the EC2 instances behind an Application Load Balancer.
D
Replace the NAT instance with a single NAT gateway in one Availability Zone. Associate the NAT gateway with all private subnets across the VPC.
E
Provision a NAT gateway in each Availability Zone. Update the private subnet route tables to use the local NAT gateway.
