AWS Certified SysOps Administrator – Associate — Question 262

A company is managing multiple AWS accounts in AWS Organizations. The company is reviewing internal security of its AWS environment. The company’s security administrator has their own AWS account and wants to review the VPC configuration of developer AWS accounts.

Which solution will meet these requirements in the MOST secure manner?

Answer options

• A. Create an IAM policy in each developer account that has read-only access related to VPC resources. Assign the policy to an IAM user. Share the user credentials with the security administrator.
• B. Create an IAM policy in each developer account that has administrator access to all Amazon EC2 actions, including VPC actions. Assign the policy to an IAM user. Share the user credentials with the security administrator.
• C. Create an IAM policy in each developer account that has administrator access related to VPC resources. Assign the policy to a cross-account IAM role. Ask the security administrator to assume the role from their account.
• D. Create an IAM policy in each developer account that has read-only access related to VPC resources. Assign the policy to a cross-account IAM role. Ask the security administrator to assume the role from their account.

Correct answer: D

Explanation

Option D is the most secure method as it uses a cross-account IAM role, allowing the security administrator to assume the role without sharing credentials. Option A and B involve sharing user credentials, which poses a security risk. Option C grants excessive permissions by providing administrator access, which is not necessary for merely reviewing VPC configurations.
