Ultimate access to all questions.
A company utilizes Amazon Route 53 to manage a public hosted zone for example.com. A network engineer recently decreased the TTL on multiple records to 60 seconds. The engineer needs to evaluate if this adjustment has caused the query volume to Route 53 to exceed the anticipated levels established prior to the change. The engineer must retrieve the total number of queries made to the example.com public hosted zone.
Which solution will deliver this information?
A
Create a new trail in AWS CloudTrail to include Route 53 data events. Send logs to Amazon CloudWatch Logs. Set up a CloudWatch metric filter to count the number of queries and create graphs.
B
Use Amazon CloudWatch to access the AWS/Route 53 namespace and to check the DNSQueries metric for the public hosted zone.
C
Use Amazon CloudWatch to access the AWS/Route 53 Resolver namespace and to check the InboundQueryVolume metric for a specific endpoint.
D
Configure logging to Amazon CloudWatch for the public hosted zone. Set up a CloudWatch metric filter to count the number of queries and create graphs.
