Selected Answer: A
The TotalErrorRate metric in CloudFront provides information about the percentage of requests that resulted in an error. It includes both 4XX (client-side) errors and 5XX (server-side) errors. By monitoring the TotalErrorRate metric, the Administrator can identify periods of increased error rates and investigate the underlying causes. This metric helps in understanding the overall health and performance of the CloudFront distribution, allowing the Administrator to take appropriate actions to address the errors and improve the customer experience.
