What is a likely consequence of setting the cache size (max_size) too small?

Frequent cache evictions, leading to a lower cache hit ratio.

Automatic purging of all cached content.

Increased cache hit ratio because the cache is more focused.

What is the effect of setting a short cache expiration time (e.g., 1 minute) on cached content?

Cached content is automatically purged using a PURGE request.

Cached content becomes stale and is revalidated or fetched from the backend more frequently.

Cached content is served to all clients regardless of the request.

Cached content is permanently deleted from the cache.

An NGINX caching proxy serves an API. The API returns responses that should be cached for 5 minutes. However, when a client sends a request with the header 'Cache-Control: no-cache', the response should not be served from cache. Which configuration achieves this?

proxy_cache_bypass $http_cache_control;

proxy_cache_key $http_cache_control;
