Which two accounts are mandatory prerequisites for the successful deployment of a VMware Cloud on AWS solution? (Choose two.)

An administrator is planning to migrate a VMware vSphere environment to VMware Cloud on AWS.
A first analysis returns the following specifications:
* 37 virtual machines will be live migrated
* All virtual machines have been created using VMware vSphere 5.0 (Compatibility Version 8)
* All virtual machines are connected to Standard Switches
* The bandwidth between the local data center and VMware Cloud on AWS is 250 Mbps What are two valid approaches for live migrating these virtual machines? (Choose two.)

An administrator deploys a virtual machine to its software-defined data center (SDDC) and configures it to perform backups of the other virtual machines in the SDDC. The administrator also creates an AWS Simple Storage Service (S3) bucket in the linked Amazon Virtual Private Cloud (VPC) and is attempting to use the S3 bucket as a repository for their backups. The administrator confirms that the backup software is capable of using AWS S3 storage as a backup repository, and that the AWS S3 bucket is configured to use an endpoint in the linked VPC.
What else should the administrator do to ensure connectivity between SDDC virtual machines and the AWS S3 repository in the linked VPC through the Elastic Network Interface?

Where would a VMware Cloud on AWS administrator generate an API token?

Upon connecting a VMware Managed Transit Gateway (VTGW), the administrator discovers that there is an overlapping workload CIDR bleck.
How will the software-defined data center (SDDC) handle the overlapping IP space?
