You are a network administrator for a medium$-$sized company. One morning, you receive multiple reports that users are unable to access the company's main customer relationship management $($CRM$)$ system. You suspect an availability issue and decide to investigate.

Which of the following steps should you take first to determine if the CRM system is experiencing unscheduled downtime?

answer

Use a site like isitdownrightnow.com to see if the issue is with the CRM provider.

Immediately start throttling client connections to reduce load on the server.

Send a probe to the CRM service to check for a non$-$error response, such as a $200$ status code.

Check the CRM system's digital certificates for expiry dates.
