   Why is NGINX considered suitable for high-traffic environments?

   • AIt uses a thread pool that scales linearly with the number of connections.
   • BIt offloads all processing to a dedicated hardware appliance.
   • CIt requires a large amount of RAM to cache all responses.
   • DIt can handle many simultaneous connections without a proportional increase in memory usage.

   How does NGINX's flexible configuration system allow customization?

   • ABy requiring a separate configuration file for each module.
   • BBy compiling a new binary for every configuration change.
   • CBy using a graphical interface to generate configuration files.
   • DBy using a hierarchical structure of directives that can be set at different contexts (http, server, location).

   An administrator is monitoring an NGINX server and notices that memory usage is very low even with thousands of active connections. Which design aspect of NGINX explains this observation?

   • ANGINX uses a single process for all connections, so memory usage is constant regardless of connections.
   • BNGINX stores all connection data on disk, not in memory.
   • CNGINX uses a small, fixed number of worker processes, each handling many connections asynchronously.
   • DNGINX compresses all data in memory, reducing the amount of memory needed per connection.

   An NGINX server is experiencing intermittent high CPU usage. The administrator suspects a misconfigured module is causing worker processes to crash. They need to change a configuration directive and ensure the change is applied without dropping existing connections. Which approach leverages NGINX's master-worker design to achieve this?

   • AEdit the configuration file and wait for the master process to automatically detect and apply the change.
   • BManually kill each worker process and rely on the master to spawn new ones with the old configuration.
   • CRun `nginx -s reload` to have the master process gracefully restart workers with the new configuration.
   • DRun `nginx -s stop` and then start NGINX again to ensure the configuration is loaded from scratch.

   A website serves a large number of static assets (images, CSS, JavaScript). The administrator wants to reduce the load on the backend application server by having NGINX serve these files directly. Which NGINX configuration approach achieves this?

   • AEnable `gzip` on the application server to compress static assets before sending.
   • BConfigure a `location` block with `root` pointing to the static files directory and `try_files` to serve them.
   • CUse `rewrite` to redirect all static asset requests to a CDN.
   • DSet `proxy_pass` to the application server for all requests, including static assets.
