Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

It allows any IAM user or role within any account belonging to the AWS Organization 'o-1234567890' to read objects.

The PrincipalOrgID condition key is a powerful tool for restricting resource access to identities within a specific AWS Organization. This allows for broad 'Allow' statements that are still safely scoped to internal users only. Mastering this condition helps in creating scalable resource-based policies that don't require listing individual account IDs, thus reducing complexity and manual errors.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • It allows any IAM user or role within any account belonging to the AWS Organization 'o-1234567890' to read objects.

    Why this is correct

    The 'aws:PrincipalOrgID' condition key filters the 'Principal: *' to only include identities that are part of the specified AWS Organization. This effectively restricts access to all members of the organization while granting them the 's3:GetObject' permission for the objects in the 'marketing-data' bucket.

  • It makes the bucket public to anyone on the internet as long as they are using an AWS account.

    Why it's wrong here

    The policy is not public. While 'Principal: *' usually indicates broad access, the 'Condition' block restricts this access to only those principals whose AWS account is a member of the specific organization ID provided. Users from accounts outside this organization will be denied access to the objects.

  • It allows access only if the S3 bucket itself is owned by the organization 'o-1234567890'.

    Why it's wrong here

    The 'aws:PrincipalOrgID' condition evaluates the organization of the principal (the user or role) making the request, not the organization of the resource owner. While the bucket likely belongs to the same organization, the policy specifically validates the identity of the caller attempting the 's3:GetObject' action.

  • It requires that the request must originate from a VPC endpoint that is tagged with the organization ID.

    Why it's wrong here

    This policy does not mention VPC endpoints or 'aws:SourceVpce'. It specifically uses the 'aws:PrincipalOrgID' key, which is used to verify the organizational membership of the IAM principal. Tagging of VPC endpoints is a separate mechanism and is not involved in the evaluation of this specific policy condition.
