   • ADefine a cache key that includes the request URI.
   • BEnable proxy_cache_lock to serialize requests to the upstream.
   • CSet proxy_cache_valid to 200 10m; for all responses.
   • DConfigure proxy_cache_use_stale to serve stale responses during upstream failures.

   • AConfigure microcaching with a cache validity of 5 seconds for the product page location.
   • BDisable caching for the product page and rely on connection pooling to the backend.
   • CEnable proxy caching with a cache validity of 1 hour for the product page location.
   • DUse content caching with a cache key that includes the user session ID.

   A company uses NGINX to cache static content. They want to ensure that when a new version of a file is deployed, clients get the new version immediately, but they also want to leverage browser caching for performance. What is the best practice?

   • AUse versioned filenames (e.g., style.v2.css) and set a long Cache-Control max-age.
   • BUse a short Cache-Control max-age of 1 minute.
   • CSet Cache-Control: no-cache for all static files.
   • DSet Cache-Control: max-age=0 for all static files.
