Overlapping Location Blocks
Server Configuration
Request Handling
Solve
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.

Medium

Securing Nginx with Rate Limiting
Security
Rate Limiting
Solve
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.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Nginx Online Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

    Load balancing involves distributing incoming network traffic across multiple servers to ensure efficient utilization of resources and improve the overall performance and availability of the application or website. This skill is crucial for handling high traffic loads and preventing server overload or downtime.

  • Reverse proxy

    A reverse proxy acts as an intermediary between client devices and web servers, forwarding client requests to the appropriate backend servers. This skill is important for increasing security, managing multiple web servers, and improving performance through caching and SSL termination.

  • Caching

    Caching involves storing frequently accessed data or web content in a temporary storage location, such as RAM or disk, to reduce the response time and server load. This skill is vital for improving the overall performance and scalability of web applications and reducing bandwidth usage.

  • Security

    Ensuring the security of the web server and the applications it hosts is crucial to protect sensitive data and prevent unauthorized access or attacks. This skill involves implementing security measures, such as firewall rules, access control, secure communication protocols, and regular security audits, to mitigate potential vulnerabilities and risks.

  • SSL/TLS

    SSL/TLS (Secure Sockets Layer/Transport Layer Security) is the standard encryption protocol used to establish secure connections between client devices and web servers. This skill is important for securing data transmission, preventing eavesdropping, and establishing trust between users and the server.

  • Performance optimization

    Performance optimization involves identifying and implementing strategies to improve the speed, efficiency, and responsiveness of web applications and websites. This skill includes techniques such as code optimization, server configuration tuning, caching mechanisms, and load testing to ensure optimal performance even under heavy loads.
