   What is the role of Amazon SNS in CloudWatch alarm notifications?

   • AIt stores alarm history for auditing
   • BIt provides a dashboard for viewing alarms
   • CIt is the target that receives alarm notifications and fans them out to subscribers
   • DIt evaluates metrics to determine alarm state

   A company runs a Kubernetes cluster on Amazon EKS and uses Prometheus for monitoring. They want to store Prometheus metrics in a fully managed service and use CloudWatch alarms to alert on high CPU usage. What should they do?

   • AInstall the CloudWatch agent as a DaemonSet in the EKS cluster and configure it to collect CPU metrics and send them to CloudWatch. Then create CloudWatch alarms on those metrics.
   • BConfigure the EKS control plane to send metrics directly to CloudWatch and create alarms on the 'CPUUtilization' metric in the AWS/EKS namespace.
   • CUse the Kubernetes Metrics Server to collect CPU metrics and store them in Amazon Managed Service for Prometheus. Then create CloudWatch alarms on the metrics in the managed service.
   • DSet up Amazon Managed Service for Prometheus and configure the Prometheus server to remote-write metrics to it. Then create CloudWatch alarms on the metrics in the managed service.

   A company monitors a critical application that runs on an EC2 instance. They have two CloudWatch alarms: one for high CPU utilization and one for high memory utilization. They want to be notified only when BOTH conditions are true, to reduce false alarms. What should they do?

   • AModify each alarm to have a longer evaluation period so they are less likely to trigger individually.
   • BCreate a single alarm on a combined metric that is the product of CPU and memory utilization.
   • CUse an EventBridge rule that triggers when either alarm changes to ALARM, and then check the other alarm's state in a Lambda function.
   • DCreate a composite alarm that includes both alarms and set it to trigger when both are in ALARM state.

   How is the CloudWatch agent typically deployed in an Amazon EKS cluster to collect metrics from all nodes?

   • AAs an AWS Lambda function
   • BAs a Kubernetes Job
   • CAs a Kubernetes DaemonSet
   • DAs a single pod in the default namespace
