   A web application allows users to upload profile photos. The application team has noticed that some users are uploading very large images (50 MB), which is consuming significant bandwidth and slowing down the upload endpoint for everyone. The team wants to limit the size of uploads without restricting how many upload requests a user can make. Which NGINX configuration should be used?

   • ASet the client_max_body_size directive to 10 MB.
   • BSet a rate limit of 5 requests per minute per user.
   • CApply a bandwidth throttle of 1 MB/s per user.
   • DSet the client_body_timeout to 10 seconds.

   A financial services company exposes a public API for balance inquiries. Recently, an attacker has been using a botnet to send thousands of requests per second from many different IP addresses, attempting to guess account numbers. The API responses are small JSON payloads, so the total bandwidth consumed is negligible. The company wants to mitigate the brute-force attack while keeping the API responsive for legitimate users. Which NGINX configuration should the administrator implement?

   • ASet a rate limit of 5 requests per second per IP address.
   • BIncrease the keepalive_timeout to 75 seconds.
   • CSet a bandwidth throttle of 100 KB/s per IP address.
   • DSet the client_max_body_size to 1 MB.

   • BNeither the number of requests nor the transfer speed
   • CThe transfer speed, not the number of requests
   • DThe number of requests, not the transfer speed
