PCA (Prometheus Certified Associate) sample exam question with answer 236

Question:
In the scrape configs for a pushgateway, what is the purpose of the honor_labels: true

scrape_configs:
  - job_name: pushgateway
    honor_labels: true
    static_configs:
      - targets: ["192.168.1.168:9091"]

1. Allows metrics to specify the instance and job labels instead of pulling it from scrape_configs
2. Prometheus will drop all labels without this config
3. Tells prometheus this is a pushgateway
4. Used to save disk space when a lot of labels are used

Answer:
A - correct answer
