Dynatrace Pro Certification Practice Exam

How can you ensure a synthetic monitor can reach your application?

1. By using a VPN

2. Whitelist IPs of the monitor location in the firewall

3. Only allowing internal access

4. Installing Dynatrace on the server

The correct answer is: Whitelist IPs of the monitor location in the firewall

To ensure that a synthetic monitor can reach your application, whitelisting the IPs of the monitor location in the firewall is effective because it allows the synthetic monitoring tool to send requests to your application without being blocked by firewall rules. Firewalls are designed to control the flow of traffic to and from a network, and if the IP addresses of the synthetic monitor are not recognized as safe or allowed, the requests from the monitor will be denied. This approach effectively facilitates continuous monitoring because it allows the monitor to directly access the application from its designated location. By pre-approving the IP addresses used by the synthetic monitor, you eliminate potential barriers that could hinder the monitoring process, ensuring that your application's performance and availability are accurately assessed. Using a VPN may provide a secure connection to access internal applications, but it doesn't directly address the specific access requirements of synthetic monitoring tools unless configured accordingly. Allowing only internal access would generally restrict any external monitoring attempts, and while installing Dynatrace on the server could provide insights into application performance, it does not ensure that synthetic monitors can reach the application over the network.
