Webhooks are cool, but not how Prometheus works.

Wait, it doesn't use a database for metrics? That's surprising!

Prometheus uses HTTP to get metrics in JSON format.

I’m a bit confused; I thought Prometheus used SNMP too, but I guess that might be for other monitoring tools.

I practiced a question similar to this, and I think it was about how Prometheus collects data from applications. I feel like it might be option C.

I remember something about it querying a database, but that doesn't sound right for Prometheus. It feels like it uses a different method.

I think Prometheus gathers metrics using HTTP, but I'm not completely sure if it's JSON encoded or something else.

I'm pretty confident that Prometheus uses a webhook approach where the monitored applications submit various metrics, so I'll select option B.

I'm not entirely sure about the details of how Prometheus gathers information, but I think the HTTP JSON option sounds the most plausible, so I'll go with C.

Ah, I remember learning about this in class. Prometheus implements the ICMP and SNMP protocols to ping and query remote services, so I'll choose option A.

Haha, I can just imagine Prometheus trying to 'ping and query' services using ICMP and SNMP. That's definitely not how it works. C is the winner!

Option E sounds interesting, but I don't think running scripts on the Prometheus server is the way it gathers information. C is definitely the right answer here.
