How does the round robin algorithm distribute requests among servers in a pool?

It selects servers sequentially in a circular order, one after another.

It uses a hash of the client IP to determine the server.

It randomly selects a server for each request.

It sends each request to the server with the fewest active connections.

When is the least_conn algorithm most beneficial compared to round robin?

When backend servers have identical hardware specifications

When all requests take the same amount of time to process

When client IP addresses need to be consistently mapped to the same server

When requests have varying processing times and some servers may be idle while others are busy

What happens to requests when a server in an upstream pool goes down?

NGINX reroutes them to the next available server in the pool

NGINX returns a 502 Bad Gateway error immediately

NGINX sends the requests to the client's browser to retry

NGINX queues the requests until the server comes back

Which configuration snippet correctly enables generic hash load balancing based on the request URI?

upstream backend { hash $remote_addr; server 10.0.0.1; server 10.0.0.2; }

upstream backend { hash $request_uri; server 10.0.0.1; server 10.0.0.2; }

upstream backend { ip_hash; server 10.0.0.1; server 10.0.0.2; }

upstream backend { least_conn; server 10.0.0.1; server 10.0.0.2; }
