SOA-C02 Practice Question: AWS Config rule with automatic SSM remediation…
This SOA-C02 practice question tests your understanding of aws config rule with automatic ssm remediation…. 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. A key principle to apply: aWS Config. 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.
The security team requires that no S3 bucket in the account ever has public read or write ACLs enabled. They want non-compliant buckets automatically remediated within 5 minutes of detection without any manual intervention. What is the correct implementation?
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
Create an AWS Config rule for s3-bucket-public-read-prohibited; configure auto-remediation using the AWS-DisableS3BucketPublicReadWrite SSM Automation document
Config evaluates the rule within seconds of a bucket ACL change. The auto-remediation action invokes the SSM document automatically when compliance status changes to NON_COMPLIANT. The SSM document calls PutBucketAcl to remove public grants. The entire cycle completes in 1-3 minutes under normal conditions.
B
Distractor review
Create an EventBridge rule that matches S3 PutBucketAcl API calls and triggers a Lambda function to re-apply a private ACL
EventBridge with a Lambda is a valid alternative that reacts to API events, but it duplicates capability that Config auto-remediation already provides natively. The Config approach is simpler to maintain (no Lambda code), produces a compliance audit trail, and is the AWS-recommended pattern for Config-based remediation.
C
Distractor review
Enable S3 Block Public Access at the account level to prevent public ACLs from being set in the first place
S3 Block Public Access is a preventive control that blocks future public ACL settings — it is the correct long-term solution and should also be implemented. However, it does not detect or remediate buckets that were already public before the setting was enabled, so the Config auto-remediation is still needed for non-compliant existing resources.
D
Distractor review
Schedule a daily Lambda function that lists all buckets, checks ACLs, and removes public grants if found
A daily schedule means a bucket can remain public for up to 24 hours before remediation. The requirement is 5 minutes. Config with auto-remediation triggers on configuration change, not on a schedule, making it far more responsive.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

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?
AWS Config
What is the correct answer to this question?
The correct answer is: Create an AWS Config rule for s3-bucket-public-read-prohibited; configure auto-remediation using the AWS-DisableS3BucketPublicReadWrite SSM Automation document — AWS Config evaluates resource configurations against rules continuously or on configuration change. When a bucket is found non-compliant, an auto-remediation action can trigger an SSM Automation document immediately. The AWS-managed SSM document AWS-DisableS3BucketPublicReadWrite removes public ACLs from the bucket. Auto-remediation can be configured to retry automatically. This produces a fully automated detect-and-remediate loop with no manual steps and typical end-to-end time well under 5 minutes.
