   An administrator configured limit_rate 256k; in a location block. After testing, the administrator observes that downloads consistently transfer at 1 MB/s, which is higher than the configured limit. Which step should the administrator take first to diagnose why the limit is not being enforced?

   • AIncrease the limit_rate value to 1m.
   • BCheck the NGINX error log for messages about bandwidth limiting.
   • CVerify that the limit_rate directive is inside the correct location block that matches the requested URI.
   • DRestart the NGINX service instead of reloading it.

   • Blimit_rate 256k;
   • Climit_rate 256k; limit_rate_after 1m;
   • Dlimit_rate_after 256k; limit_rate 1m;

   An NGINX server hosts an API that returns large JSON payloads. During a traffic spike, the server's network interface becomes saturated, and the API becomes unresponsive. The operations team wants to protect the server by limiting the amount of data each client can receive per second, while still allowing unlimited requests per second. Which directive should be added to the server block?

   • Aclient_body_timeout 512k;
   • Blimit_rate 512k;
   • Climit_conn_zone $binary_remote_addr zone=api:10m;
   • Dlimit_req zone=api burst=10;

   A video streaming service uses NGINX to serve content. The administrator wants to give users on a fast network a higher bandwidth limit than users on a slow network. The administrator has a map that sets $network_speed to 'fast' or 'slow' based on the client's IP address. Which configuration applies a different bandwidth limit based on $network_speed?

   • Aset $limit_rate $network_speed;
   • Blimit_rate $network_speed;
   • Climit_rate_after $network_speed;
   • Dlimit_rate $limit_rate;
