AWS Certified Solutions Architect – Associate (SAA-C03) — Question 981

A company has five organizational units (OUs) as part of its organization in AWS Organizations. Each OU correlates to the five businesses that the company owns. The company's research and development (R&D) business is separating from the company and will need its own organization. A solutions architect creates a separate new management account for this purpose.

What should the solutions architect do next in the new management account?

Answer options

• A. Have the R&D AWS account be part of both organizations during the transition.
• B. Invite the R&D AWS account to be part of the new organization after the R&D AWS account has left the prior organization.
• C. Create a new R&D AWS account in the new organization. Migrate resources from the prior R&D AWS account to the new R&D AWS account.
• D. Have the R&D AWS account join the new organization. Make the new management account a member of the prior organization.

Correct answer: B

Explanation

An AWS account can only be a member of a single AWS Organization at any given time. Therefore, the R&D account must first leave its current organization before it can accept an invitation to join the newly created organization. Option B is correct because it describes this exact migration workflow, whereas Option A is impossible, Option C introduces unnecessary migration overhead, and Option D is architecturally incorrect.
