Correct Answer: A
AWS Cloudformation is an application management tool which provides application modelling, deployment, configuration, management and related activities. It supports a wide variety of AWS services, such as EC2,
EBS, AS, ELB, RDS, VPC, etc. It also provides application bootstrapping scripts which enable the user to install software packages or create folders. It is free of the cost and only charges the user for the services created with it. The only challenge is that it does not follow any model, such as DevOps; instead customers can define templates and use them to provision and manage the AWS resources in an orderly way.Question #78

- D. Auto Scaling sends data every minute only and does not charge the user
Correct Answer: B
CloudWatch is used to monitor AWS as well as the custom services. It provides either basic or detailed monitoring for the supported AWS products. In basic monitoring, a service sends data points to CloudWatch every five minutes, while in detailed monitoring a service sends data points to CloudWatch every minute. Auto
Scaling includes 7 metrics and 1 dimension, and sends data to CloudWatch every 5 minutes by default. The user can enable detailed monitoring for Auto Scaling, which sends data to CloudWatch every minute.
However, this will have some extra-costs.
