A financial institution has the following security requirements:

Cloud-based users must be contained in a separate authentication domain.

Cloud-based users cannot access on-premises systems.

As part of standing up a cloud environment, the financial institution is creating a number of Amazon managed databases and Amazon EC2 instances. An Active Directory service exists on-premises that has all the administrator accounts, and these must be able to access the databases and instances.

Answers
E.
Establish a two-way trust between the new and existing Active Directory services.
Suggested answer: A, D

Explanation:

Deploy a new forest/domain on AWS with one-way trust. If you are planning on leveraging credentials from an on-premises AD on AWS member servers, you must establish at least a one-way trust to the Active Directory running on AWS. In this model, the AWS domain becomes the resource domain where computer objects are located and on-premises domain becomes the account domain.
