What is the purpose of the `listen` directive inside a stream server block?

To specify the backend server's IP address

To define the load balancing method

To enable SSL termination for the stream

To set the port on which NGINX accepts incoming layer 4 traffic

What is a passive health check in NGINX layer 4 load balancing?

NGINX uses an external script to check the health of backend servers.

NGINX monitors backend responses to actual client connections and marks a server down after a certain number of failures.

NGINX checks the backend's CPU and memory usage to decide if it is healthy.

NGINX periodically sends a TCP connection to the backend to verify it is healthy.

What is the purpose of the `auth_request` directive in NGINX?

To redirect unauthenticated users to a login page

To encrypt API requests with TLS

To validate API keys by making a subrequest to an authentication service

To limit the number of API requests per client

A healthcare company is deploying an API gateway with NGINX. The gateway must route requests to different backend services based on the URI path. Additionally, requests to the /admin path must require JWT authentication, while other paths are public. The administrator also needs to apply a rate limit of 5 requests per second to the /admin path only. Which configuration approach should be used?

Use a location block for /admin with the auth_jwt directive and limit_req directive, and separate location blocks for other paths without these directives

Configure the auth_jwt and limit_req directives in the server block and use the satisfy directive to control access

Use a single location block for all paths with the auth_jwt directive and limit_req directive

Use the map module to set a variable based on the URI and apply auth_jwt and limit_req conditionally with if statements
