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


Configuration for SSL
SSL Configuration
Performance Tuning
Server Blocks
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.



Overlapping Location Blocks
Server Configuration
Request Handling
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.


Securing Nginx with Rate Limiting
Rate Limiting
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.
