Full question →hardmultiple choiceObjective-mapped
A company's security policy requires that all Amazon S3 buckets must be non-publicly accessible. The SysOps administrator needs to automatically detect any bucket that becomes publicly accessible and automatically remediate it by applying a bucket policy that blocks public access. The solution should use AWS managed services with minimal custom code. Which combination of services 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
Distractor review
AWS IAM Access Analyzer with Amazon EventBridge
Detects public access but does not provide automatic remediation.
B
Best answer
AWS Config with managed rule and automatic remediation via SSM Automation
Evaluates compliance and automatically applies remediation using managed automation.
C
Distractor review
AWS CloudTrail and AWS Lambda
Requires custom Lambda code to detect and remediate.
D
Distractor review
AWS Trusted Advisor and Amazon SNS
Provides recommendations only, no automatic remediation.
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: AWS Config with managed rule and automatic remediation via SSM Automation — AWS Config with a managed rule like s3-bucket-public-read-prohibited evaluates buckets for public access. Automatic remediation can be enabled using an AWS Systems Manager Automation document that applies a bucket policy to block public access. This approach requires minimal custom code. AWS IAM Access Analyzer detects public access but does not automatically remediate. CloudTrail with Lambda would require custom code. Trusted Advisor only provides recommendations.
