True or false: A CloudWatch namespace must be preceded with AWS.
True or false: Metrics come in two types: Normal and Detailed.

A new compliance requirement has been introduced in your company that dictates that all EC2 system slogs need to be redirected to a central data store where they can be accessed and then stored durably in an archive. How could you achieve this?
Your application is divided into three functional environments: Test, Staging, and Production, each composed of EC2 autoscaling clusters, RDS databases, and ElastiCache cluster. A requirement to maintain alerts of CPU usage on all instances only on the Production environment is set out by a governance policy. How can you implement your CloudWatch Alarms to achieve this in the most efficient manner?
What would a number in a CloudWatch Dashboard represent?
You are asked by your developers to create an alarm when 10% of the SNS messages to a particular topic are not delivered. How could this be done?
You are running an e-commerce application that starts performing slowly when the number of concurrent connections to your frontend is above 100,000. This kind of volume is unusual and only happens during seasonal sales (3–4 times per year). During the last sale, you analyzed the metrics and discovered that your ELB and your EC2 instances are responding correctly and the latency issue is being caused by the RDS backend being hit by a high number of requests. Due to the fact that you need to keep costs as low as possible, increasing the size of your instance permanently isn't an option. You know the thresholds at which the application starts to perform slowly. Come up with a solution that will temporarily increase the performance of the database during these few events
