   An organization is choosing between NGINX and a traditional hardware load balancer for a high-traffic web application. They have a limited budget and need to handle sudden spikes in traffic. Which factor most strongly favors NGINX?

   • ANGINX is easier to configure than hardware load balancers.
   • BNGINX provides built-in hardware acceleration for SSL/TLS termination.
   • CNGINX supports more load balancing algorithms than hardware load balancers.
   • DNGINX's event-driven architecture allows it to handle high concurrency with lower resource usage.

   Which characteristic of NGINX's event-driven architecture contributes to its effectiveness as a load balancer?

   • AIt uses a single-threaded event loop per worker to handle many connections concurrently with low overhead.
   • BIt relies on the operating system's kernel to schedule all network I/O operations.
   • CIt dedicates a separate CPU core to each upstream server to maximize throughput.
   • DIt spawns a new process for each incoming connection to isolate failures.

   What is the purpose of configuring SSL/TLS termination on an NGINX load balancer?

   • ATo authenticate upstream servers using client certificates.
   • BTo encrypt traffic between NGINX and the upstream servers.
   • CTo redirect all HTTP traffic to HTTPS automatically.
   • DTo decrypt incoming HTTPS traffic at NGINX and forward it to upstream servers over plain HTTP.
