Question 1

A company is developing a web application that runs on Amazon EC2 Linux instances. The application requires monitoring of custom performance metrics. The company must collect metrics for API response times and database query latency across multiple instances. Which solution will generate the custom metrics with the LEAST operational overhead?

A : Install the Amazon CloudWatch agent on the instances. Configure the agent to collect the custom metrics. Instrument the application to send the metrics to the agent.

B : Use Amazon Managed Service for Prometheus to scrape the custom metrics from the application. Use the Amazon CloudWatch agent to forward the metrics to CloudWatch.

C : Create a custom AWS Lambda function that polls the application endpoints and database at regular intervals. Program the Lambda function to calculate the custom metrics and to send the metrics to Amazon CloudWatch by using PutMetricData API calls.

D : Implement custom logging in the application code to record the custom metrics. Use Amazon CloudWatch Logs Insights to extract and analyze the metrics.

Answer: A

Question 2

A : Create an Amazon CloudWatch log group. Create an AWS CloudTrail trail that writes to the CloudWatch log group.

B : Create a new Amazon S3 bucket. Configure default audit logging on the Redshift cluster. Configure the S3 bucket as the target.

C : Configure the Redshift cluster database audit logging to include user activity logs. Configure Amazon CloudWatch as the target.

D : Create an Amazon CloudWatch dashboard that has a log widget. Configure the widget to display user details from the Redshift logs.

E : Create an AWS Lambda function that uses Amazon Athena to query the Redshift logs. Create an Amazon CloudWatch dashboard that has a custom widget type that uses the Lambda function.

Answer: B,D

Question 3

A DevOps engineer is creating a CI/CD pipeline to build container images. The engineer needs to store container images in Amazon Elastic Container Registry (Amazon ECR) and scan the images for common vulnerabilities. The CI/CD pipeline must be resilient to outages in upstream source container image repositories. Which solution will meet these requirements?

A : Create an ECR private repository in the private registry to store the container images and scan images when images are pushed to the repository. Configure a replication rule in the private registry to replicate images from upstream repositories.

B : Create an ECR public repository in the public registry to cache images from upstream source repositories. Create an ECR private repository to store images. Configure the private repository to scan images when images are pushed to the repository.

C : Create an ECR public repository in the public registry. Configure a pull through cache rule for the repository. Create an ECR private repository to store images. Configure the ECR private registry to perform basic scanning.

D : Create an ECR private repository in the private registry to store the container images. Enable basic scanning for the private registry, and create a pull through cache rule.

Answer: C

Question 4

A company runs an Amazon EKS cluster and must implement comprehensive logging for the control plane and nodes. The company must analyze API requests and monitor container performance. Which solution will meet these requirements with the LEAST operational overhead?

A : Enable AWS CloudTrail for control plane logging and deploy Logstash on nodes.

B : Enable control plane logging to CloudWatch and use CloudWatch Container Insights for node and pod metrics.

C : Enable API server logging to S3 and deploy Kubernetes Event Exporter to nodes.

D : Use AWS Distro for OpenTelemetry and stream logs to Amazon Redshift.

Answer: B

Question 5
