Sample SOA-C03 questions

A CloudOps engineer is examining the following AWS CloudFormation template: Why will the stack creation fail?
  1. The Outputs section of the CloudFormation template was omitted.
  2. The Parameters section of the CloudFormation template was omitted.
  3. The PrivateDnsName cannot be sot from a CloudFormation template.
  4. The VPC was not specified in the CloudFormation template.
Show answerC — The PrivateDnsName cannot be sot from a CloudFormation template.
The PrivateDnsName of an EC2 instance is assigned automatically by AWS from the VPC and subnet IP addressing and cannot be set directly as a property in a CloudFormation template. Trying to set it causes stack creation to fail validation. The Outputs and Parameters sections are both optional in CloudFormation, so omitting them never causes a failure. The VPC does not need to be specified either; if omitted, the instance launches into the default VPC and default subnet.
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?
  1. It takes at least 30 days to be able to use tags to filter views in Cost Explorer.
  2. The company has not activated the user-defined tags for cost allocation.
  3. The company has not created an AWS Cost and Usage Report.
  4. The company has not created a usage budget in AWS Budgets.
Show answerB — The company has not activated the user-defined tags for cost allocation.
User-defined tags do not appear in Cost Explorer until they are activated as cost allocation tags in the Billing and Cost Management console. Applying tags to resources alone is not enough. Activation typically takes up to 24 hours, not 30 days, so the 30-day waiting option is wrong. A Cost and Usage Report and AWS Budgets are separate billing tools and are not prerequisites for filtering Cost Explorer views by tags. The fix is to activate the tags on the cost allocation tags page.
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?
  1. Create an additional CloudWatch agent configuration filo to capture the DHCP logs. Use the AWS Systems Manager Run Command to restart the CloudWatch agent on each EC2 instance with the append- config option to apply the additional configuration file.
  2. Log in to each EC2 instance with administrator rights. Create a PowerShell script to push the needed baseline log files and DHCP log files to CloudWatch.
  3. Run the CloudWatch agent configuration file wizard on each EC2 instance. Verify that the baseline log files are included and add the DHCP log files during the wizard creation process.
  4. Run the CloudWatch agent configuration file wizard on each EC2 instance and select the advanced detail level. This will capture the operating system log files.
Show answerA — Create an additional CloudWatch agent configuration filo to capture the DHCP logs. Use the AWS Systems Manager Run Command to restart the CloudWatch agent on each EC2 instance with the append- config option to apply the additional configuration file.
The CloudWatch agent supports multiple configuration files, and the append-config option on the fetch-config action lets you layer an additional configuration onto the running agent without losing the baseline. Using Systems Manager Run Command to restart the agent with the extra config file on the 50 targeted instances is the most operationally efficient path. Logging in manually to each instance or rerunning the wizard on each instance does not scale and is error prone, and the wizard's advanced detail level does not specifically capture DHCP logs.
