How we design questions

These are just a small sample from our library of 10,000+ questions. The actual questions on this Nginx Online Test will be non-googleable.

🧐 Question
Medium Configuration for SSL SSL Configuration Performance Tuning Server Blocks	Try practice test
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. 1. 2. 3. 4. 5.
Easy Overlapping Location Blocks Server Configuration Request Handling	Try practice test
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	Try practice test
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.

What topics are covered in the Nginx Online Test?

Nginx configuration
Nginx configuration refers to setting up and managing the various parameters and directives of the Nginx web server. This skill is essential to ensure optimal performance, security, and reliability of the server, as well as to customize the server to meet specific requirements.
Load balancing
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.
Logging and monitoring
Logging and monitoring involve keeping track of server logs, system metrics, and application performance to identify issues, troubleshoot errors, and proactively manage the server infrastructure. This skill is essential for maintaining server health, diagnosing performance bottlenecks, and detecting security breaches.
HTTP server
The HTTP server component of Nginx handles incoming HTTP requests, processes them, and returns the appropriate HTTP responses. This skill is necessary for serving web content, handling different HTTP methods, managing URL routing, and implementing various HTTP-related features.
HTTPS server
HTTPS server refers to the configuration and management of Nginx to handle secure HTTPS (HTTP over SSL/TLS) connections. This skill involves setting up SSL certificates, enforcing secure communication, and configuring HTTPS-related features like HSTS (HTTP Strict Transport Security) and secure ciphers.

Nginx Hiring Test FAQs

Can I combine multiple skills into one custom assessment?

Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify. Here's a quick guide on how you can request a custom test.

Do you have any anti-cheating or proctoring features in place?

We have the following anti-cheating features in place:

Non-googleable questions
IP proctoring
Screen proctoring
Web proctoring
Webcam proctoring
Plagiarism detection
Secure browser
Copy paste protection

Read more about the proctoring features.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

Does every candidate get the same questions?

Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.
