Question 1 of 200

A CloudOps engineer is examining the following AWS CloudFormation template:

Exam AWS Certified CloudOps Engineer - Associate SOA-C03: Question 1 - Image 1

Why will the stack creation fail?

Answer choices
Show answer

Correct answer: C

PrivateDnsName is not a configurable property of an AWS::EC2::Instance resource in CloudFormation. AWS assigns an EC2 instance’s private DNS name automatically based on the instance’s private IP address and the VPC DNS settings. Including an unsupported property causes CloudFormation template validation or stack creation to fail. The subnet determines the VPC context, so a separate VPC property is not required for the instance.

Question 2 of 200

A company applies user-defined tags to resources that are associated with the company's AWS workloads. Twenty days after applying the tags, the company notices that it cannot use the tags to filter views in the AWS Cost Explorer console.

What is the reason for this issue?

Answer choices
Show answer

Correct answer: B

User-defined tags must be activated as cost allocation tags in the AWS Billing and Cost Management console before they can be used in Cost Explorer. Applying a tag to resources alone does not make its cost data available for filtering or reporting. After activation, AWS begins processing the tag for cost allocation, which can take up to 24 hours for new data to appear. A Cost and Usage Report or a budget is not required to filter Cost Explorer by activated tags.

Question 3 of 200

An environment consists of 100 Amazon EC2 Windows instances. The Amazon CloudWatch agent is deployed and running on all EC2 instances with a baseline configuration file to capture log files. There is a new requirement to capture the DHCP log files that exist on 50 of the instances.

What is the MOST operationally efficient way to meet this new requirement?

Answer choices
Show answer

Correct answer: A

An additional CloudWatch agent configuration can be appended to the existing baseline configuration, preserving current log collection while adding DHCP logs only where needed. AWS Systems Manager Run Command performs this change remotely across the selected 50 instances, avoiding individual administrative logins. The append-config option lets the agent merge the new log collection settings without replacing the baseline configuration.

Question 4 of 200

A company is storing backups in an Amazon S3 bucket. The backups must not be deleted for at least 3 months after the backups are created.

What should a CloudOps engineer do to meet this requirement?

Answer choices
Show answer

Correct answer: B

S3 Object Lock in compliance mode enforces a write-once-read-many retention period, preventing any user, including the root user, from deleting or overwriting protected backups before the 3-month period expires. Object Lock must be enabled when a bucket is created, so the backups need to be stored in a new bucket. Governance mode can be bypassed by authorized users with special permissions, while compliance mode cannot be bypassed during retention.

Question 5 of 200

A company's CloudOps engineer is troubleshooting communication between the components of an application. The company configured VPC flow logs to be published to Amazon CloudWatch Logs However, there are no logs in CloudWatch Logs.

What could be blocking the VPC flow logs from being published to CloudWatch Logs?

Answer choices
Show answer

Correct answer: A

The flow log delivery role needs permission to create the CloudWatch Logs log group when it does not already exist. Without logs:CreateLogGroup, VPC Flow Logs cannot create the required destination and log publishing can fail. The role also requires permissions such as logs:CreateLogStream and logs:PutLogEvents to deliver records. Export tasks, IPv6 configuration, and VPC peering do not prevent flow logs from being sent to CloudWatch Logs.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla

The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.
