A solutions architect is importing a VM from an on-premises environment by using the Amazon EC2 VM Import feature of AWS Import/Export. The solutions architect has created an AMI and has provisioned an Amazon EC2 instance that is based on that AMI. The EC2 instance runs inside a public subnet in a VPC and has a public IP address assigned.
The EC2 instance does not appear as a managed instance in the AWS Systems Manager console.
Which combination of steps should the solutions architect take to troubleshoot this issue? (Choose two.)

A. Verify that Systems Manager Agent is installed on the instance and is running
B. Verify that the instance is assigned an appropriate IAM role for Systems Manager.
C. Verify the existence of a VPC endpoint on the VPC.
D. Verify that the AWS Application Discovery Agent is configured.
E. Verify the correct configuration of service-linked roles for Systems Manager.
