A Developer wants to debug an application by searching and filtering log data. The application logs are stored in Amazon CloudWatch Logs. The Developer creates a new metric filter to count exceptions in the application logs. However, no results are returned from the logs.
What is the reason that no filtered results are being returned?

• A.The log group for CloudWatch Logs should be first streamed to Amazon Elasticsearch Service before metric filtering returns the results
• B.A setup of the Amazon CloudWatch interface VPC endpoint is required for filtering the CloudWatch Logs in the VPC
• C.Metric data points for logs groups can be filtered only after they are exported to an Amazon S3 bucket
• D.CloudWatch Logs only publishes metric data for events that happen after the filter is created
