   A company runs a web application on three backend servers. They want NGINX to distribute incoming traffic across these servers and automatically stop sending requests to a backend that becomes unresponsive. Which set of NGINX features should they use?

   • AConfigure `upstream` with `server` directives and set `proxy_pass` to the upstream group.
   • BUse `alias` and `try_files` to serve static copies of the application from NGINX.
   • CEnable `ssi` and `sub_filter` to modify responses from a single backend.
   • DSet `listen` to the backend server IP addresses and use `root` to serve the application.

   A company runs a high-traffic e-commerce site. They currently use a thread-based web server and are experiencing high CPU usage and memory exhaustion during peak hours. They are evaluating NGINX as a reverse proxy and static content server. The team is concerned about the learning curve and operational changes. Which factor is most important in deciding whether NGINX will solve their resource issues?

   • ANGINX's configuration syntax is similar to Apache, so the team can migrate with minimal training.
   • BNGINX's event-driven architecture will reduce memory and CPU usage by handling many connections with fewer processes.
   • CNGINX provides a graphical management interface that simplifies monitoring.
   • DNGINX can be installed as a drop-in replacement without changing any application code.

   What is a primary reason NGINX is highly efficient at serving static content?

   • AIt uses an event-driven model and optimized file I/O like sendfile to minimize overhead.
   • BIt stores all static content in a database for quick retrieval.
   • CIt requires a separate caching server to achieve efficiency.
   • DIt compiles static files into binary format for faster access.

   What design feature allows NGINX to handle high concurrency with a low memory footprint?

   • AIt stores all connection state in a shared database.
   • BIt uses a separate process for every request to ensure isolation.
   • CA small number of worker processes handle many connections using an event loop.
   • DEach connection is handled by a dedicated thread with a large stack.
