In an NGINX reverse proxy configuration, what does NGINX do when a health check indicates that an upstream server is unavailable?

It restarts the upstream server automatically

It removes the server from the configuration permanently

It continues to send traffic to the server but logs a warning

It immediately stops all traffic to that server and sends requests to other available servers

Which of the following is true about active health checks in open source NGINX?

They are available in open source NGINX when compiled with the `--with-healthcheck` flag

They are enabled by default in open source NGINX for all upstream groups

They can be configured using the `proxy_next_upstream` directive

They are a feature of NGINX Plus and are not available in open source NGINX

What is the primary purpose of health checks in NGINX when configured as a reverse proxy?

To cache responses from upstream servers to improve performance

To balance the load evenly among all upstream servers regardless of their state

To encrypt traffic between NGINX and upstream servers

To monitor the availability of upstream servers and avoid sending requests to servers that are down

A company is considering moving from open source NGINX to NGINX Plus to get active health checks. They want to understand the key difference. Which statement correctly describes active health checks in NGINX Plus?

NGINX Plus sends periodic synthetic requests to upstream servers, independent of client traffic.

NGINX Plus uses the same passive health check mechanism as open source, but with more configurable parameters.

Active health checks only work with HTTP upstreams, not TCP or UDP.

Active health checks require a separate module that must be compiled from source.
