An organization is planning to implement a solution to ease the administrative effort of managing access permissions of AWS accounts and applications. Because of this initiative, the organization plans to manage the access to AWS accounts and applications centrally. Which of the below would you suggest?

Answer options:

A.AWS SSO
B.AWS Identity and Access Management (IAM)
C.AWS Account Manager
D.AWS Resource Access Manager (RAM)

Answer: A
Option A is correct. AWS Single Sign-On (SSO) simplifies access management and manages access to multiple AWS accounts and business applications centrally.
Option B is incorrect. AWS Identity and Access Management (IAM) deals with access management, providing the ability to manage access to AWS services and resources securely. Using IAM, AWS users and groups could be created and managed. You can also add permissions to allow or deny access to AWS resources.
Option C is incorrect. AWS Account Manager is not a valid offering from AWS.
Option D is incorrect. AWS Resource Access Manager (RAM) is a service that enables users to share AWS resources easily and securely. The resources could be shared with any AWS account or within your AWS Organization.
