A company uses a large, growing, and high performance on-premises Microsoft SQL Server instance With an Always On availability group cluster size of 120 TIE. The company uses a third-party backup product that requires system-level access to the databases. The company will continue to use this third-party backup product in the future.

The company wants to move the DB cluster to AWS with the least possible downtime and data loss. The company needs a 2 Gbps connection to sustain Always On asynchronous data replication between the company's data center and AWS.

Answers
F.
Configure the third-party backup product to perform backups of the DB cluster on Amazon EC2.
Suggested answer: A, D, F

Explanation:

A. Establish an AWS Direct Connect hosted connection between the company's data center and AWS. This will provide a secure and high-bandwidth connection for the Always On data replication and minimize the network latency and data loss.

D. Deploy a new SQL Server Always On availability group DB cluster on Amazon EC2. Configure Always On distributed availability groups between the on-premises DB cluster and the AWS DB cluster. Fail over to the AWS DB cluster when it is time to migrate. This will allow the company to use the same SQL Server version and edition as on-premises, and leverage the distributed availability group feature to span two separate availability groups across different locations. The failover process will be fast and seamless, with minimal downtime and data loss.

F. Configure the third-party backup product to perform backups of the DB cluster on Amazon EC2. This will enable the company to continue using their existing backup solution, which requires system-level access to the databases. Amazon RDS for SQL Server does not support system-level access, so it is not a suitable option for this requirement.
