An admin needs to restart NGINX to apply a new binary that was installed. They want to minimize the impact on users. What is the best approach?

Run `nginx -t` to apply the new binary.

Run `nginx -s reload` to apply the new binary.

Run `nginx -s stop` and then start NGINX.

Run `nginx -s quit` and then start NGINX.

During a reload, what happens to a long-lived WebSocket connection that is currently active?

It is paused until the reload completes, then resumes.

It is immediately terminated to make way for the new worker processes.

It is migrated to a new worker process seamlessly.

It continues on the old worker process until the connection closes.

An admin changes the `keepalive_timeout` and `gzip` settings in nginx.conf. They want to apply the changes with minimal disruption to a live e-commerce site. Which command should they use?

`kill -9 $(cat /var/run/nginx.pid)`

`nginx -s stop` followed by `nginx`

During a graceful reload, what happens to the old worker processes?

They are converted into new workers with the updated configuration.

They are immediately terminated as soon as the reload signal is received.

They are shut down gracefully after finishing their current connections.

They continue running indefinitely alongside the new workers.

An admin needs to apply a new `server` block that listens on a different port. The current NGINX is serving production traffic. What is the best approach?

Run `nginx -t` to validate and apply the config.

Run `nginx -s quit`, edit the config, then start NGINX.

Edit the config and run `nginx -s reload`.

Run `nginx -s stop`, edit the config, then start NGINX.
