Exam AWS-SysOps topic 1 question 17 discussion

Exam question from Amazon's AWS-SysOps

Question #: 17
Topic #: 1

An application that you are managing has EC2 instances & Dynamo OB tables deployed to several AWS Regions in order to monitor the performance of the application globally, you would like to see two graphs:
1) Avg CPU Utilization across all EC2 instances
2) Number of Throttled Requests for all DynamoDB tables.
How can you accomplish this?

A. Tag your resources with the application name, and select the tag name as the dimension in the Cloudwatch Management console to view the respective graphs
B. Use the Cloud Watch CLI tools to pull the respective metrics from each regional endpoint Aggregate the data offline & store it for graphing in CloudWatch.
C. Add SNMP traps to each instance and DynamoDB table Leverage a central monitoring server to capture data from each instance and table Put the aggregate data into Cloud Watch for graphing.
D. Add a CloudWatch agent to each instance and attach one to each DynamoDB table. When configuring the agent set the appropriate application name & view the graphs in CloudWatch.

Correct Answer: A In 2019 AWS launched Cross account/cross region dashboards, which enable you to create high level operational dashboards, with the ability to visualize, aggregate, and summarize performance and operational data across accounts and Regions The ability to visualize, aggregate, and summarize performance and operational data across accounts and Regions helps reduce mean time to resolution. With cross-account cross-region dashboards, you get centralized visibility of CloudWatch metrics, logs, and alarms across a group of related accounts without the overhead of having to centralize data. Likewise, you can visualize the health and performance of applications running in several Regions. You can also use CloudWatch metric math to aggregate and transform metrics from multiple accounts and Regions. So, Cross-Region functionality is now built-in automatically. You do not need to take any extra steps to be able to display metrics from different Regions in a single account on the same graph or the same dashboard.

Selected Answer: A

A. Tagging resources is a fundamental best practice in AWS. CloudWatch's dimension filtering directly supports using tags, making it easy to aggregate metrics across regions based on application names. This method requires minimal setup and avoids complex data aggregation.

I voted for D. By adding a CloudWatch agent to each EC2 instance and attaching one to each DynamoDB table, you can collect the necessary metrics. The agent allows you to customize the configuration, including specifying the application name. This enables you to differentiate the metrics from multiple instances and tables when viewing the graphs in CloudWatch.
