Which high-availability pattern involves running multiple Prometheus servers that scrape the same targets and using a load balancer to serve queries?

Running multiple Prometheus servers with identical scrape configs and a load balancer in front

Using federation to replicate data between servers

Running Prometheus servers in HA pairs with shared storage

Using the Pushgateway to aggregate metrics from all servers

What is the purpose of Prometheus federation?

To combine multiple Prometheus servers into a single cluster with shared storage

To replicate data between Prometheus servers for high availability

To send alerts from one Prometheus server to another

To allow one Prometheus server to scrape selected time series from another Prometheus server

In Prometheus alerting rules, what does the `expr` field contain?

The labels to attach to the alert

The duration for which the condition must hold

The PromQL expression that defines the alert condition
