Answer : C

AWS Fargate should be used to optimize the cost of a containerized application by eliminating the need for manual instance management, as it provides serverless container orchestration that automatically scales and charges only for resource usage. The WGU Cloud Deployment and Operations Study Guide (Section 7.5, Fargate) states, 'Fargate optimizes costs for containerized applications by removing the overhead of managing EC2 instances, scaling automatically, and billing based on vCPU and memory usage, reducing manual deployment expenses.' Aurora, RDS, and EFS are database or storage solutions not designed for container cost optimization.

Answer : C

Comprehensive and Detailed Explanation From Exact Extract:

The Mappings section in a CloudFormation template should be used to set values based on region-specific AMI IDs. Mappings allow the template to define a lookup table that associates regions with corresponding AMI IDs, enabling dynamic selection during stack creation across multiple regions. The WGU Cloud Deployment and Operations Study Guide (Section 5.3, CloudFormation Mappings) states, 'The Mappings section enables region-specific configurations, such as mapping AMI IDs to regions (e.g., 'us-east-1': 'ami-123456'), ensuring the correct AMI is used based on the deployment region.' Outputs, WaitCondition, and Resources do not provide this mapping functionality.

Answer : B

Amazon Route 53 is the AWS solution that sends DNS queries to separate AWS compute instances by leveraging routing policies to distribute traffic across multiple resources. It acts as a scalable Domain Name System (DNS) service, directing queries to healthy instances based on configurations like latency or weighted routing. The WGU Cloud Deployment and Operations Study Guide (Section 3.1, Route 53) states, 'Route 53 uses DNS to route end-user requests to multiple AWS compute instances, supporting features like health checks and traffic distribution.' Elastic Beanstalk, CloudWatch, and EC2 Auto Scaling do not perform DNS query routing.

Answer : A

The Enterprise support plan provides a technical account manager (TAM) and full use of Trusted Advisor, offering proactive guidance and comprehensive access to all checks. This plan is designed for large-scale, mission-critical workloads. The WGU Cloud Deployment and Operations Study Guide (Section 6.4, AWS Support Plans) states, 'The Enterprise support plan includes a dedicated Technical Account Manager and full Trusted Advisor access, providing 24/7 support and proactive optimization recommendations.' Developer, Standard, and Business plans offer limited or no TAM support and partial Trusted Advisor access.

Answer : C

In AWS Systems Manager, the error threshold for automation documents is configured using rate control. Rate control allows administrators to define the maximum number of errors or concurrent executions that can occur before an automation task is throttled or stopped, ensuring system stability. The WGU Cloud Deployment and Operations Study Guide (Section 5.1, Systems Manager Automation) explicitly states, 'Rate control settings in Automation documents can be used to specify the maximum number of errors allowed during execution, helping to manage error thresholds effectively.' Resource groups, session preferences, and maintenance windows do not directly address error thresholds.
