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?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
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
Distractor review
Origin Access Identity (OAI)
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
Distractor review
Signed URLs
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
Distractor review
AWS WAF web ACL associated with the CloudFront distribution
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.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 1
A company uses Amazon CloudFront to deliver content to a global audience. The origin is an Application Load Balancer in us-east-1. The SysOps administrator wants to reduce costs by minimizing the number of requests that reach the origin server. Which action should the administrator take?
Question 2
A company runs a batch processing application on Amazon EC2 that runs for 2 hours every night. The workload can tolerate interruptions. Which EC2 purchasing option provides the lowest cost for this use case?
Question 3
A SysOps administrator needs to monitor the CPU utilization of an Amazon RDS DB instance and receive an alarm when CPU utilization exceeds 80% for 5 consecutive minutes. Which AWS service should be used to create this alarm?
Question 4
A company runs a critical web application on Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). The application uses session stickiness (sticky sessions) to maintain user sessions. The SysOps administrator notices that when instances are replaced during a scale-in or failure event, users lose their session data. The administrator needs to preserve session data across instance failures without losing stickiness benefits. What should the administrator do?
Question 5
A company runs a production web application on a single Amazon EC2 instance. The application experiences a predictable and steady workload 24/7. The SysOps administrator wants to minimize compute costs for this instance while ensuring it remains available during the expected workload. Which EC2 purchasing option should the administrator use?
Question 6
A company has a VPC with public and private subnets. The private subnets host application servers that need to make outbound HTTPS connections to the internet. The SysOps administrator must implement a solution that provides outbound internet connectivity while preventing inbound connections from the internet. Additionally, the solution must allow the company to control which domains the application servers can access. Which solution should the administrator implement?
FAQ
Questions learners often ask
What does this SOA-C02 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Geographic restrictions (geo-blocking) in CloudFront — CloudFront Geographic Restrictions (also known as geo-blocking) allows you to whitelist or blacklist countries from accessing your content. This is the simplest way to restrict access based on geography. Origin Access Identity (OAI) is used to restrict access to S3 origins, not ALB. Signed URLs or signed cookies control access per user, not per geography. AWS WAF can also be used for geo-matching, but it requires additional configuration and integrates with CloudFront via web ACLs. The question asks for a CloudFront feature; geographic restrictions are a native CloudFront capability.
