To optimize performance, an administrator wants to enable persistent connections (keep-alives) between NGINX and a pool of upstream HTTP/1.1 application servers. Which THREE configurations are required to achieve this? (Select THREE)
Company Alpha is running a file hosting service. They are experiencing issues where malicious users open hundreds of slow connections to tie up server resources, but each connection only downloads data at a very slow rate. The architect wants to limit the number of concurrent connections per IP address to 5. Which directive correctly establishes the shared memory zone required for this connection limiting?
True or False: The NGINX `keepalive_timeout` directive sets the maximum time a keep-alive client connection will stay open on the server side, and its default value is 0 (which disables keep-alives).
An administrator needs to enforce a dynamic bandwidth limit. Clients authenticating as 'premium' users should have no bandwidth limit (0), while 'standard' users should be limited to 100k per second. The user type is extracted to a variable named `$user_bandwidth_limit`. Which directive correctly applies this dynamic limit in a location block?
What is the primary difference between rate limiting (`limit_req`) and bandwidth throttling (`limit_rate`) in NGINX?
