Question 41 of 75 | ← Chapter 2

Q191. A company uses a Grafana data visualization solution that runs on a single Amazon EC2 instance to monitor the health of the company's AWS workloads. The company has invested time and effort to create dashboards that the company wants to preserve. The dashboards need to be highly available and cannot be down for longer than 10 minutes. The company needs to minimize ongoing maintenance. Which solution will meet these requirements with the LEAST operational overhead?

• A. Migrate to Amazon CloudWatch dashboards. Recreate the dashboards to match the existing Grafana dashboards. Use automatic dashboards where possible
• B. Create an Amazon Managed Grafana workspace. Configure a new Amazon CloudWatch data source. Export dashboards from the existing Grafana instance. Import the dashboards into the new workspace ✓
• C. Create an AMI that has Grafana pre-installed. Store the existing dashboards in Amazon Elastic File System (Amazon EFS). Create an Auto Scaling group that uses the new AMI. Set the Auto Scaling group's minimum, desired, and maximum number of instances to one Create an Application Load Balancer that serves at least two Availability Zones
• D. Configure AWS Backup to back up the EC2 instance that runs Grafana once each hour. Restore the EC2 instance from the most recent snapshot in an alternate Availability Zone when required

Correct Answer: B. Create an Amazon Managed Grafana workspace. Configure a new Amazon CloudWatch data source. Export dashboards from the existing Grafana instance. Import the dashboards into the new workspace

Explanation

Option A requires recreating the dashboards from scratch in Amazon CloudWatch, which can be time- consuming and may not preserve all of the desired functionality from the existing Grafana instance. Option C involves creating a custom AMI with Grafana pre-installed, which can require ongoing maintenance to ensure that it stays up to date. It also assumes that the Grafana instance will always run on a single EC2 instance, which does not provide high availability. Option D only provides backup and restore capabilities, but does not address the need for high availability or minimizing ongoing maintenance. Option B involves creating an Amazon Managed Grafana workspace, which reduces operational overhead by having AWS manage the Grafana infrastructure. The existing dashboards can be exported from the current instance and imported into the new workspace, preserving the investment made in creating them. Adding a new Amazon CloudWatch data source enables the company to continue monitoring AWS workloads while maintaining high availability.
