You need to analyze the response time of the product catalog page during peak times, from different
locations.
What should you do?

Configure endpoint monitoring.

B.
Add the Requests metric.

C.

Explanation:
Endpoint monitoring configures web tests from geo-distributed locations that test response time and
uptime of web URLs. The test performs an HTTP get operation on the web URL to determine the response
time and uptime from each location. Each configured location runs a test every five minutes.
After you configure endpoint monitoring, you can drill down into the individual endpoints to view details
response time and uptime status over the monitoring interval from each of the test location
