Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To specify the IP address of the target server.
Why it's wrong here
Target IPs are specified in the Prometheus scrape configuration, not the exporter module.
- ✗
To manage the authentication credentials for the exporter process.
Why it's wrong here
Authentication is handled via the scrape configuration or exporter flags, not the module definition.
- ✓
To define the protocol-specific behavior and parameters for the probe.
Why this is correct
Modules encapsulate configuration settings like timeouts and HTTP matchers for specific probes.
- ✗
To automatically register the exporter with the Prometheus server.
Why it's wrong here
Exporter registration occurs through target configuration, not exporter internal modules.
