The `GetSessionToken` API call is needed to perform MFA before accessing a resource, as it generates temporary security credentials for an IAM user after MFA validation. This ensures secure access to AWS resources. The WGU Cloud Deployment and Operations Study Guide (Section 6.2, IAM and MFA) states, 'The `GetSessionToken` API is used with MFA to obtain temporary credentials, requiring a valid MFA code to authenticate the user before resource access is granted.' GetCallerIdentity, GetFederationToken, and DecodeAuthorizationMessage serve different purposes and do not handle MFA authentication.

Amazon RDS Performance Insights supports retention periods of 7 days and 1 year for storing performance data, depending on the configuration and edition. The default retention is 7 days for standard monitoring, while enabling enhanced monitoring or the Performance Insights extended retention feature allows data to be retained for up to 1 year. The WGU Cloud Deployment and Operations Study Guide (Section 7.2, Performance Insights) states, 'Performance Insights offers a 7-day retention period by default, with an option to extend to 1 year for detailed historical analysis, supporting cost and performance optimization.' Options A (1 day) and D (2 years) are not supported retention periods.

When Amazon Route 53 determines an endpoint is unhealthy based on a failure threshold (e.g., via health checks), it terminates the connection attempt to that endpoint and routes traffic to a healthy alternative, if available. This behavior ensures high availability using routing policies like failover or latency-based routing. The WGU Cloud Deployment and Operations Study Guide (Section 3.1, Route 53 Health Checks) states, 'Route 53 stops routing traffic to an unhealthy endpoint by terminating connection attempts once the health check failure threshold is exceeded, redirecting to a healthy resource.' Options A, C, and D are not direct actions taken by Route 53 in this scenario.

Patch Manager in AWS Systems Manager sends compliance reports to an Amazon S3 bucket, where they are stored for auditing and analysis. This allows administrators to track patch compliance status across EC2 instances and on-premises servers. The WGU Cloud Deployment and Operations Study Guide (Section 5.2, Patch Manager) states, 'Patch Manager compliance reports are delivered to an S3 bucket configured as a target, providing a centralized location for reviewing patch status and compliance data.' OpsWorks, EBS, and Route 53 are not used for storing these reports.

Comprehensive and Detailed Explanation From Exact Extract:

To make the EC2 instance accessible via a public DNS hostname like ec2-public-54.18.127.233.us-west-2.compute.amazonaws.com, the administrator must set the VPC attribute enableDnsHostnames to true. This enables the automatic assignment of public DNS hostnames to instances with public IP addresses in the VPC. The WGU Cloud Deployment and Operations Study Guide (Section 3.2, VPC Configuration) states, 'Setting enableDnsHostnames to true in the VPC configuration ensures that EC2 instances with public IPs receive a public DNS hostname (e.g., ec2-public-<ip>.<region>.compute.amazonaws.com), facilitating internet accessibility.' Resource tags, disabling DNS support, and resource-based names do not enable this functionality.</region></ip>
