A solutions architect needs to migrate an on-premises legacy application to AWS. The application runs on two servers behind a load balancer. The application requires a license file that is associated with the MAC address of the server's network adapter. It takes the software vendor 12hours to send new license files. The application also uses configuration files with a static IP address to access a database server. host names are not supported. Given these requirements, which combination of steps should be taken to enable highly available architecture for the application servers in AWS? (Select TWO)

Explanation:
ENI to resolve the Mac address restrictions. Having the license files on an Amazon S3 bucket reduces the management overhead for the EC2 instances, as you can easily add/remove more license keys if needed. Having the database IP addresses on Parameter Store ensures that all the EC2 instances will have a central location to retrieve the IP addresses. This also reduces the need to constantly update any script from inside the EC2 instance even if you add/remove more databases in the future.
