Adaface Sample Nginx Questions

An organization wants to configure an Nginx server to serve both HTTP and HTTPS traffic efficiently. The requirements are as follows: redirect all HTTP traffic to HTTPS, utilize the SSL protocol for secure communication, and ensure optimal performance by enabling gzip compression for text files. Given the configuration snippets below, select the correct combination that meets these requirements.

An Nginx server is configured with multiple `location` blocks that overlap in their path specifications, leading to potential ambiguity in request handling. Given the following configuration snippets, identify which `location` block will handle a request to the URL `/images/thumbnails/large/photo.jpg`:
            
            1. `location = /images/thumbnails/large/photo.jpg { ... }`
            2. `location ^~ /images/thumbnails/ { ... }`
            3. `location ~* \.(jpg|png)$ { ... }`
            4. `location /images/ { ... }`

A: Location block 1 will handle the request because it exactly matches the request URI.
            B: Location block 2 will handle the request because it matches the prefix and disables regex checking.
            C: Location block 3 will handle the request because it matches the case-insensitive regex for file extensions.
            D: Location block 4 will handle the request because it has the longest matching prefix.
            E: All of the above location blocks will handle the request in the order they are defined.

You are tasked with enhancing the security of an Nginx server by implementing rate limiting to protect against brute-force attacks. The requirement is to limit requests to the login page (/login) to no more than 10 requests per minute for each IP address, while ensuring legitimate users are not adversely affected by false positives. Which configuration snippet correctly sets up rate limiting for this purpose?

A: Configuring the limit_rate directive to 10 requests per minute directly inside the /login location block.
            B: Setting the limit_conn directive to 10 inside the /login location block to restrict concurrent connections.
            C: Using the limit_req directive inside the http block without defining a limit_req_zone.
            D: Applying a deny all directive inside the /login location block for requests exceeding 10 per minute.
            E: Defining a limit_req_zone directive outside the server block with a rate of 10r/m and applying it to the /login location using the limit_req directive.
