A media company hosts large video files for authenticated customers. Support tickets indicate that a few users are saturating the uplink, causing slow downloads for everyone else. The company wants to cap each download at 2 MB/s without affecting the rate at which new requests are accepted. Which configuration should an NGINX administrator apply inside the location block that serves the video files?

limit_req zone=downloads burst=20 nodelay;

An administrator configured limit_rate 1m; in a location block that serves large files. After reloading NGINX, the administrator wants to verify that the limit is actually being enforced. Which method provides the most direct evidence that the bandwidth limit is working?

Run nginx -t and check for syntax errors in the configuration.

Use the limit_req_status directive to see the HTTP status code returned.

Check the NGINX error log for messages about rate limiting.

Download a large file from the location and observe the transfer speed in a browser or download manager.

An NGINX server hosts a web application that experiences intermittent spikes in traffic. The application is CPU-bound, and the server becomes overloaded when too many requests arrive simultaneously. The administrator wants to protect the server by limiting the number of requests per second, not the download speed. Which directive should be used?

limit_req zone=app burst=20 nodelay;

limit_conn_zone $binary_remote_addr zone=app:10m;
