Question
A company uses Amazon Route 53 to host a public hosted zone for example.com. A network engineer recently reduced the TTL on several records to 60 seconds. The network engineer wants to assess whether the change has increased the number of queries to Route 53 beyond the expected levels that the company identified before the change. The network engineer must obtain the number of queries that have been made to the example.com public hosted zone.
Which solution will provide 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.
Answer
B. Use Amazon CloudWatch to access the AWS/Route 53 namespace and to check the DNSQueries metric for the public hosted zone.
Explanation
The solution that provides the required information on the number of queries made to the example.com public hosted zone is Option B. Using Amazon CloudWatch to access the AWS/Route 53 namespace and checking the DNSQueries metric for the public hosted zone will give the query count.
CloudWatch offers metrics specific to Route 53 services. By accessing the DNSQueries metric within the AWS/Route 53 namespace, the network engineer can monitor and assess the number of queries made to the example.com public hosted zone.
This solution directly fetches the required metric without the need for additional setup or complex configurations, providing a straightforward way to evaluate the query volumes accurately.
