A customer has an application that is used by enterprise customers outside of AWS. Some of these customers use legacy firewalls that cannot whitelist by DNS name, but whitelist based only on IP address. The application is currently deployed in two Availability Zones, with one EC2 instance in each that has Elastic IP addresses. The customer wants to whitelist only two IP addresses, but the two existing EC2 instances cannot sustain the amount of traffic. What can a Solutions Architect do to support the customer and allow for more capacity

Switch the two existing EC2 instances for an auto scaling group and registered them with the network load balancer

Create a network load balancer with an interface in each subnet, and assign a static IP address to each subnet.
