   A company runs a web application where certain API endpoints should not be cached, while static assets should be cached for a long time. They are using NGINX as a reverse proxy. How can they achieve this with NGINX configuration?

   • ASet 'proxy_cache_valid' to a long duration for all responses.
   • BConfigure 'proxy_cache_key' to include the request body for API requests.
   • CUse the 'expires' directive in the server block to set cache headers for all responses.
   • DUse 'proxy_cache_bypass' and 'proxy_no_cache' directives in location blocks for the API endpoints.

   A company runs a web application that serves both dynamic content and static assets. They want to use NGINX as a reverse proxy to cache static assets to reduce backend load. However, they need to ensure that cached content is invalidated when the underlying files change. What should they configure?

   • AUse the 'expires' directive to set a long cache lifetime for static assets.
   • BSet 'proxy_cache_bypass' to always bypass the cache for static assets.
   • CUse the 'proxy_cache_valid' directive to set a short cache duration for all content.
   • DConfigure 'proxy_cache_key' to include the file modification time.

   Which architectural characteristic of NGINX allows it to handle a large number of simultaneous connections with relatively low memory and CPU usage?

   • AIt creates a dedicated thread for each request and schedules them on multiple CPUs.
   • BIt relies on a single-threaded, blocking I/O model for all client requests.
   • CIt spawns a new operating system process for each client connection.
   • DIt uses an asynchronous, event-driven model where a small number of worker processes handle many connections.
