You work in a large organization. Your team creates AWS resources such as Amazon EC2 dedicated hosts and reserved capacities that need to be shared by other AWS accounts. You need an AWS service to centrally manage these resources so that you can easily specify which accounts or Organizations can access the resources. Which AWS service would you choose to meet this requirement?

Answer options:

A.IAM
B.Resource Access Manager
C.Service Catalog
D.AWS Single Sign-On

Correct Answer – B
AWS Resource Access Manager (AWS RAM) helps users to share resources with other AWS accounts or Organizations. Refer to the reference in https://docs.aws.amazon.com/ram/latest/userguide/what-is.html.
Option A is incorrect: Because IAM cannot be used to manage and share these resources.
Option B is CORRECT: EC2 dedicated hosts and reserved capacities are shareable resources that are supported by Resource Access Manager. Check the reference in https://docs.aws.amazon.com/ram/latest/userguide/shareable.html.
Option C is incorrect: Because Service Catalog is used to manage catalogs and cannot share resources with others.
Option D is incorrect: Because AWS Single Sign-On is used for SSO access and does not share the mentioned resources.
