Which of the following is NOT an option for agentless injection?

Agentless injection methods allow for the incorporation of monitoring capabilities without the need for a dedicated agent on the application environment. The options listed highlight different methodologies for implementing this type of injection, with only one incorrect choice regarding agentless processes.

The correct answer indicates that supported technology injection through OneAgent does not fall under agentless injection options. OneAgent is a dedicated agent that runs on hosts to capture detailed application performance metrics. It embeds monitoring directly into the application code, typically for environments where deeper insights are needed. In contrast, agentless options typically involve approaches that do not require this kind of direct integration, making this method distinctly reliant on installation and presence of an agent.

The other options represent various ways to achieve agentless monitoring. Loading JavaScript files from Dynatrace's CDN allows for monitoring without needing to install an agent as it pulls monitoring code directly from a web-accessible source. Inline code addition involves manually inserting the monitoring code within the application’s HTML, which is again a method that does not rely on an agent. Lastly, writing the JavaScript script to a file on the server also bypasses the need for an agent by directly modifying the existing application environment to include monitoring scripts.

Therefore, the choice that refers to OneAgent clearly indicates
