   A startup is building a public API for its new service. The team expects rapid growth and wants to add new endpoints frequently without changing the client-facing URL structure. They also want to enforce rate limits and collect metrics. Which NGINX deployment is most appropriate?

   • AUse NGINX as a TCP load balancer for database connections.
   • BDeploy NGINX as an API gateway with dynamic upstream configuration and built-in rate limiting and logging.
   • CDeploy NGINX as a mail proxy for internal communication.
   • DUse NGINX as a static file server to serve API documentation.

   A media company runs a legacy monolithic application that is being gradually decomposed. During the transition, some clients still call the monolith's old /api/v1 endpoints, while new mobile clients use /api/v2 backed by three new microservices. The company needs a single entry point that can route based on URL prefix, apply a shared API key check, and gradually shift traffic from the monolith to the new services without changing client code. Which approach best fits this scenario?

   • AReplace the monolith with a service mesh sidecar on every pod to handle routing and authentication.
   • BConfigure each microservice to independently validate API keys and expose its own public endpoint.
   • CDeploy NGINX as an API gateway with location-based routing for /api/v1 to the monolith and /api/v2 to the microservices, plus a shared auth check.
   • DUse a cloud load balancer that distributes traffic evenly across the monolith and all microservices.

   A company exposes an API that returns sensitive data. The security team requires that all API traffic be encrypted in transit and that the backend servers do not handle TLS termination. Which NGINX configuration should be used?

   • AConfigure NGINX to terminate TLS with SSL certificates and proxy requests to the backend over HTTP.
   • BUse NGINX as a load balancer without any TLS configuration.
   • CConfigure NGINX to pass through TLS without termination, forwarding encrypted traffic to the backend.
   • DDisable TLS and rely on the private network for security.
