This SAP-C02 practice question tests your understanding of design solutions for organizational complexity. 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 company wants to implement a data perimeter to ensure that only authorized accounts can access their S3 buckets. Which TWO steps should they take?
Use SCPs to deny access from external accounts.
Prevents access from accounts outside organization.
Use VPC endpoints with bucket policies.
Why wrong: Controls network access, not account.
Use S3 bucket policy with aws:SourceAccount condition.
Restricts access to specific accounts.
Enable CloudTrail to log access.
Why wrong: Logging, not enforcing.
Use AWS Network Firewall.
Why wrong: Network-level, not account-level.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use SCPs to deny access from external accounts.
Option B is correct because bucket policy with aws:SourceAccount condition ensures only specific accounts. Option D is correct because SCPs can deny access from outside the organization. Option A is wrong because it's for CloudTrail. Option C is wrong because it's for VPC endpoints. Option E is wrong because it's for network perimeter, not account-level.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Use SCPs to deny access from external accounts.
Why this is correct
Prevents access from accounts outside organization.
Related concept
Standard ACLs match source addresses.
Use VPC endpoints with bucket policies.
Why it's wrong here
Controls network access, not account.
Use S3 bucket policy with aws:SourceAccount condition.
Why this is correct
Restricts access to specific accounts.
Related concept
Standard ACLs match source addresses.
Enable CloudTrail to log access.
Why it's wrong here
Logging, not enforcing.
Use AWS Network Firewall.
Why it's wrong here
Network-level, not account-level.
Common exam traps
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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.
What to study next
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related SAP-C02 ACL questions on filtering logic and placement.
