PCA (Prometheus Certified Associate) sample exam question with answer 422

Question:
How does Prometheus determine the path on which to scrape targets?

1. Via the globally configured metrics_path attribute in the Prometheus configuration file
2. Via the per-job metrics_path attribute in the Prometheus configuration file
3. Via the globally configured --metrics-path command line flag
4. Via the per-job --metrics-path-<job> command line flag

Answer:
B - correct answer. More at scrape_config
A - is incorrect as this attribute is actually set per-scrape, not globally
C, D - is incorrect as there is no such command line flag
