An environment has 12 individual CloudWatch metric alarms covering CPU, memory, disk, and network. When one instance degrades, all 12 alarms fire simultaneously and send 12 separate notifications to the on-call engineer. The team wants a single notification per incident regardless of how many individual alarms trigger. What CloudWatch feature addresses this?

A company needs to retain API call logs for 7 years for compliance. Which AWS service should be used to store these logs?

Refer to the exhibit. The command returns no datapoints for CPUUtilization for the specified instance. What is the most likely reason?

Refer to the exhibit. The alarm has been in INSUFFICIENT_DATA state for several hours. What is the most likely cause?

A company is using AWS Lambda functions to process incoming messages from Amazon SQS. The Lambda function sometimes fails due to a transient error, and the message is not processed. The team wants to automatically retry failed messages and send them to a dead-letter queue (DLQ) after three failed attempts. Which configuration meets these requirements?

An application running on EC2 instances behind an Application Load Balancer (ALB) sends custom metrics to CloudWatch. The team wants to set an alarm that triggers when the error rate exceeds 5% over a 5-minute period. The alarm must evaluate the metric every minute. Which configuration is required?

An application writes logs to a file on an EC2 instance. The SysOps team needs to send these logs to Amazon CloudWatch Logs in real time. The logs must be encrypted at rest in CloudWatch Logs using a customer-managed KMS key. Which steps are required?

A SysOps administrator needs to monitor the CPU utilization of an Amazon RDS for PostgreSQL instance and receive an alert if the usage exceeds 80% for 5 consecutive minutes. The database is in a production environment. What is the MOST efficient way to achieve this?

Refer to the exhibit. A SysOps administrator runs this CloudWatch Logs Insights query against an application log group. The query returns no results, even though the administrator knows that errors occurred in the last hour. What is the most likely cause?

A company uses CloudWatch Logs to collect application logs from EC2 instances. The logs are critical for troubleshooting. The operations team notices that some log entries are missing during peak hours. The CloudWatch Logs agent is configured with a batch size of 1 MB and a batch timeout of 10 seconds. Which TWO actions should the administrator take to reduce the chance of missing log events?

A SysOps administrator manages a fleet of EC2 instances that run a batch processing job. The job runs every hour and takes about 45 minutes to complete. The administrator wants to be notified if any job takes longer than 1 hour. Currently, the administrator uses CloudWatch Logs to capture job start and end times from application logs. The job writes a log message at start with 'JOB_START' and at end with 'JOB_END'. The administrator wants to create a metric filter that counts jobs that exceed 1 hour. However, the administrator is unsure how to achieve this with CloudWatch Logs. What should the administrator do?

A company runs a critical web application on a fleet of EC2 instances behind an Application Load Balancer (ALB). The instances are in an Auto Scaling group. The operations team uses CloudWatch alarms to monitor the application's health. Recently, they noticed that the application's error rate has increased sporadically, but the CPU utilization and memory usage remain normal. The team suspects that the issue is related to a specific HTTP endpoint returning 5xx errors. They want to set up monitoring that will alert them when the error rate exceeds 5% of total requests over a 5-minute period. The application logs are already sent to CloudWatch Logs. Which combination of steps should the SysOps administrator take to meet this requirement?
