Geographic restrictions (geo-blocking) in CloudFront
CloudFront supports geo-restriction natively. You can create a whitelist or blacklist of allowed countries using the CloudFront console or API. This directly meets the requirement.
- B
Origin Access Identity (OAI)
Why wrong: OAI is used to restrict access to an Amazon S3 origin so that only CloudFront can fetch objects. It does not apply geographic restrictions to the content delivered.
- C
Signed URLs
Why wrong: Signed URLs or signed cookies control access on a per-user basis by requiring a signature. They do not restrict by geographic location; they are used to verify that the viewer is authorized.
- D
AWS WAF web ACL associated with the CloudFront distribution
Why wrong: AWS WAF can filter requests based on geography using geo match conditions. However, this is not a native CloudFront feature; it requires an additional service. The question asks for a CloudFront feature, and geographic restrictions in CloudFront are simpler and more direct.
Quick Answer
The answer is CloudFront geographic restrictions, also known as geo-blocking. This feature works by examining the geographic location of the viewer’s IP address and then either allowing or denying access to content based on the country or region you specify, making it the simplest and most direct method for restricting content by location without modifying the ALB origin or adding authentication. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your ability to differentiate between CloudFront’s native access controls—like geo-restriction—and other features such as signed URLs or WAF rules, which are more complex or serve different purposes. A common trap is confusing geo-restriction with origin access control; remember that geo-blocking is applied at the CloudFront edge, not at the origin. Memory tip: think “geo = geography, block = location” to instantly recall that this feature uses the viewer’s IP to enforce country-level restrictions.
SOA-C02 Networking and Content Delivery Practice Question
This SOA-C02 practice question tests your understanding of networking and content delivery. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 deliver content from an Application Load Balancer (ALB) origin. The SysOps administrator needs to restrict access to the content so that only users from a specific geographic location can view it. Which CloudFront feature should be used?

Correct answer & explanation
Geographic restrictions (geo-blocking) in CloudFront
CloudFront's geographic restrictions (geo-blocking) feature allows you to restrict access to content based on the geographic location of the viewer's IP address. This is the simplest and most direct method to ensure only users from a specific country or region can access the content delivered through CloudFront, without requiring any changes to the origin or additional authentication mechanisms.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS WAF's geo-match rules with CloudFront's built-in geographic restrictions, but the question asks for a CloudFront feature, and the native geo-blocking feature is the correct, simpler answer without requiring an additional service.
Detailed technical explanation
How to think about this question
CloudFront's geo-restriction feature works by using a third-party GeoIP database to map the viewer's IP address to a country, then either allowing or blocking requests based on the configured allow list or block list. This feature operates at the CloudFront edge location, meaning requests are rejected before they reach the origin, reducing origin load and latency for blocked users. Note that geo-restriction is based on the viewer's IP address, which can be inaccurate if the user is behind a VPN or proxy, and it cannot restrict based on sub-country regions like states or cities.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
