   A web application serves both static files and dynamic content from a backend. The administrator wants to cache static files in the browser and also cache backend responses in NGINX to reduce load. Which set of directives achieves both goals?

   • AUse expires for static files and proxy_cache_path with proxy_cache for backend responses
   • BUse try_files for static files and proxy_redirect for backend responses
   • CUse add_header Cache-Control for static files and proxy_pass for backend responses
   • DUse gzip for static files and proxy_buffering for backend responses

   A web application has two server blocks: one for www.example.com and one for api.example.com. Both listen on port 443 with different SSL certificates. A client sends a request to https://api.example.com/status. How does NGINX determine which server block handles this request?

   • AIt uses the Host header from the request to match the server_name directive
   • BIt uses the first server block defined in the configuration file
   • CIt uses the source IP address of the client to select the server block
   • DIt uses the URI path to select the server block

   • BThe upstream block with the least_conn directive and passive health checks

   A junior administrator is reviewing an NGINX configuration and sees the following structure: a main block, an events block, and an http block. Inside the http block, there are multiple server blocks, each containing location blocks. What is the correct description of this hierarchy?

   • AThe main context defines worker processes, events defines virtual hosts, http defines upstreams, and location defines SSL settings
   • BThe main context holds global settings, events configures the connection-processing model, http contains server blocks, and location blocks define URI-specific behavior
   • CThe http block can contain multiple events blocks, and each server block must have at least one location block
   • DThe events block is optional and can be omitted, while the http block is only needed for reverse proxying
