Which metric can the Administrator use to monitor the elevated error rates in CloudFront?

Explanations:

The TotalErrorRate metric in CloudFront tracks the number of HTTP 4XX and 5XX response codes generated by CloudFront, making it ideal for monitoring elevated error rates related to customer connection issues.

The RejectedConnectionCount metric monitors the number of connections that CloudFront rejects due to SSL/TLS handshake errors or connection limits, not HTTP error responses.

The NetworkTransmitThroughput metric measures the amount of data transmitted by CloudFront over the network, not related to HTTP error codes or error rates.

The HealthyHostCount metric tracks the number of healthy origins in CloudFront, but it does not directly monitor HTTP error rates. It’s more focused on the health of backend resources.
