Dynatrace Pro Certification Practice Exam

Under what condition will automatic injection of RUM JavaScript tags occur?

1. Process is blacklisted

2. Host is running in cloud infra mode

3. Process is not a Windows protected process

4. Host has insufficient permissions

The correct answer is: Process is not a Windows protected process

Automatic injection of Real User Monitoring (RUM) JavaScript tags occurs when the process is not a Windows protected process. In general, the automatic injection of tags is designed to enable seamless monitoring of web applications without the need for manual implementation. Windows protected processes are typically system-critical and have restrictions that prevent external modifications or injection of code, which is why RUM tags cannot be automatically injected into these processes. When a process is not protected, it allows Dynatrace to inject the necessary JavaScript tags directly into the pages served by that process, facilitating the capture of real-user metrics, such as load times, interactions, and errors. This capability is essential for capturing comprehensive performance data, aiding in analyzing user experience effectively. The other conditions relate to scenarios where the automatic injection would be prevented but do not directly support the process of tag injection. For example, if a host is blacklisted or running in a mode that limits its functionality, or if it has insufficient permissions, it would hinder the process, thus making it unable to utilize the automatic injection of RUM tags.
