Answer: Create a pool of ENIs. Request license files from the vendor for the pool, and store the license files in Amazon S3 Create a bootstrap automation script to download a license file and attach the corresponding ENI to an Amazon EC2 instance, Edit the bootstrap automation script to read the database server IP address from the AWS Systems Manager Parameter Store, and inject the value into the local configuration files
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.

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)
A
Create a pool of ENIs. Request license files from the vendor for the pool, and store the license files in Amazon S3 Create a bootstrap automation script to download a license file and attach the corresponding ENI to an Amazon EC2 instance
B
Create a pool of ENIs Request license files from the vendor for the pool, store the license files on an Amazon EC2instance Create an AMI from the instance and use this AMI for all future EC2 instances
C
Create a bootstrap automation script to request a new license file from the vendor When the response is received, apply the license fie to an Amazon EC2 instance
D
Edit the bootstrap automation script to read the database server IP address from the AWS Systems Manager Parameter Store, and inject the value into the local configuration files
E
Edit an Amazon EC2 instance to include the database server IP address in the configuration files and re-create the AMI to use for all futureEC2 instances
