In an NGINX mirroring configuration, what is the effect of the `mirror` directive?

It sends a copy of the request to the specified location while continuing to process the original request.

It redirects the client to a different URL.

It blocks requests that match the specified pattern.

It changes the upstream server for the current request.

An administrator wants to restrict access to a load-balanced application to only a specific set of IP addresses. They also want to allow all other traffic to be rejected with a 403 response. Which configuration is correct?

Use `deny` directives for the allowed IPs and an `allow all;` directive in the `location` block.

Use `return 403;` for all requests and then use `proxy_pass` to forward allowed IPs.

Use `limit_req` to restrict access to the allowed IPs.

Use `allow` directives for the allowed IPs and a `deny all;` directive in the `location` block.

What is the primary purpose of tuning the size of a shared memory zone used for session persistence in NGINX?

To control the maximum number of concurrent connections per client.

To reduce the latency of SSL/TLS handshakes.

To increase the number of worker processes.

To ensure the zone can store enough session state entries for the expected number of clients.

An administrator is tuning NGINX for a load-balanced application that uses both rate limiting and session persistence. They notice that the shared memory zones are consuming too much memory. What is the best way to reduce memory usage while maintaining functionality?

Use a single shared memory zone for both rate limiting and session persistence.

Increase the `worker_processes` value to distribute memory usage.

Reduce the size of the `limit_req_zone` and use a smaller `zone` size for session persistence.

Disable session persistence and rely on round-robin load balancing.
