A company is planning to migrate a legacy application, comprising a single application server and a Microsoft SQL Server database server, from their on-premises data center to AWS. Each server is currently hosted on a VMware VM, which collectively uses 500 TB of data across multiple attached storage volumes. The company has already set up a 10 Gbps AWS Direct Connect link from their nearest AWS Region to their on-premises facility, which is not being utilized by other services at the moment. What are the optimal steps for a solutions architect to minimize downtime during this migration? (Select two options.)

Explanation:
The correct answers are options A and D. Given the large size of the data (500 TB), AWS Server Migration Service (AWS SMS) is the optimal tool for replicating VMs to AWS with minimal downtime. Option A specifies using AWS SMS for the database server, while option D refers to using AWS SMS for the application server. Using these tools together will ensure a seamless migration process. Option E, which involves AWS Database Migration Service (AWS DMS), is not ideal for this scenario due to the size limitations of Amazon RDS, and options B and C do not provide the most efficient or least disruptive method for this large-scale migration.
