Quick Answer
The answer is the `aws:PrincipalOrgID` condition key. This key is the correct choice because it allows you to restrict S3 bucket access to a specific AWS organization by evaluating the organization ID of the principal’s account, ensuring that only accounts within that organization can perform the action, regardless of which individual account or role makes the request. On the AWS Certified Security Specialty SCS-C02 exam, this concept tests your understanding of how to enforce cross-account boundaries using organization-level policies rather than account-level conditions; a common trap is confusing it with `aws:SourceOrgID` (used for resource-based policies on services like SQS or SNS) or with `aws:PrincipalOrgPaths`, which is more granular for organizational units. To remember it, think of the key as checking the “Org ID” of the principal—like a membership badge that proves the account belongs to your organization’s team.
This SCS-C02 practice question tests your understanding of identity and access management. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security engineer must ensure that cross-account access to an S3 bucket is restricted to only accounts that are part of a specific AWS organization. Which IAM policy condition key should be used in the bucket policy?
aws:SourceIp
Why wrong: Checks source IP address, not organization.
aws:MultiFactorAuthPresent
Why wrong: Checks for MFA, not organization membership.
aws:PrincipalOrgID
Checks that the principal's account is in the specified AWS organization.
aws:SourceVpce
Why wrong: Checks VPC endpoint, not organization.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
aws:PrincipalOrgID
Option D is correct because 'aws:PrincipalOrgID' condition key checks that the principal's account belongs to a specific AWS organization. Option A is for MFA. Option B is for source IP. Option C is for VPC endpoint.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
