The correct answer is to use CloudFront geographic restriction, which allows you to whitelist or blacklist countries directly within the distribution settings. This built-in feature works by checking the requester’s IP address against a country-level database, enabling straightforward content control without additional services. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your ability to distinguish between native CloudFront capabilities and more complex alternatives like Lambda@Edge or WAF geo-match conditions. A common trap is assuming S3 bucket policies can handle geographic restrictions—they cannot, as S3 lacks IP-based country awareness. Another pitfall is overcomplicating the solution with Lambda@Edge when the built-in geo-restriction is simpler and sufficient for most use cases. Remember the memory tip: “Geo-block at the edge, not the bucket,” meaning always prefer CloudFront’s native restriction over S3 policies or custom code for country-level access control.
SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. 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 uses Amazon CloudFront to distribute content globally. The company wants to restrict access to content based on geographic location. Which TWO actions can the company take?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use CloudFront geo-restriction to allow or block countries.
Option A is correct because CloudFront geo-restriction allows whitelisting or blacklisting countries. Option D is correct because the geographic restriction feature is built-in. Option B is incorrect because S3 bucket policies do not support geographic restrictions. Option C is incorrect because Lambda@Edge can be used but is more complex. Option E is incorrect because WAF can block based on country using geo match conditions.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Configure an S3 bucket policy to deny access from specific IP ranges.
Why it's wrong here
S3 bucket policies do not have geographic condition keys.
✓
Use CloudFront geo-restriction to allow or block countries.
Why this is correct
Directly restricts access by country.
Related concept
Standard ACLs match source addresses.
✓
Associate an AWS WAF web ACL with the CloudFront distribution and use a geo match condition.
Why this is correct
WAF geo match condition can be used with CloudFront to block countries.
Related concept
Standard ACLs match source addresses.
✓
Use CloudFront geographic restriction.
Why this is correct
Same as A, but rephrased; correct.
Related concept
Standard ACLs match source addresses.
✗
Use Lambda@Edge to check the request's country and return a 403.
Why it's wrong here
Possible but not a built-in feature.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
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.
KKey Concepts to Remember
Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.
TExam Day Tips
→Check inbound versus outbound direction.
→Read the ACL from top to bottom.
→Look for a broader permit or deny above the intended line.
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
How this comes up in practice
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
Got this wrong? Here's your next step.
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.
