A developer is emitting a custom metric to CloudWatch that tracks the number of orders processed per region. The developer wants to be able to filter and aggregate the metric by region. What should the developer include in the metric data?

A timestamp with the region name

A namespace with the region name

A dimension with the region name

A developer needs to notify the operations team when a deployment completes successfully and when a service quota is about to be exceeded. The notifications should be sent to an email distribution list. What is the most efficient way to implement this?

Use Amazon SES to send emails directly from the application and from the deployment script.

Create a CloudWatch dashboard that shows deployment status and quota usage.

Use AWS Lambda to poll for deployment status and quota usage, then send emails via SES.

Publish messages to an SNS topic from the deployment pipeline and from a CloudWatch alarm on the quota metric.
