   • BAccess logging using the access_log directive.
   • CContent caching using the proxy_cache_path and proxy_cache directives.

   An administrator has configured NGINX as a reverse proxy with an upstream block containing two backend servers. They notice that one backend server is receiving significantly more traffic than the other, even though they expected even distribution. They have not configured any load-balancing method. What is the most likely reason for this imbalance?

   • AThe default round-robin method is being used, but the servers have different weights configured.
   • BThe server with more traffic has a higher max_fails setting, causing it to be selected more often.
   • CThe ip_hash method is being used, which routes clients to the same server based on IP.
   • DThe least_conn method is being used, which sends more traffic to the server with fewer connections.

   A company has two different web applications: one for customer-facing traffic (www.example.com) and one for internal admin traffic (admin.example.com). They want to use a single NGINX server to route requests to the correct backend based on the hostname. What is the most appropriate configuration?

   • AUse the map directive to assign a backend based on the client IP address.
   • BCreate a single server block and use the rewrite directive to change the URI based on the hostname.
   • CCreate two separate server blocks, each with a server_name directive matching the respective hostname and a proxy_pass directive to the correct backend.
   • DConfigure two upstream blocks and use the proxy_pass directive with a variable in a single server block.
