How can you specify conditional exports in a Node.js package?

Add a `condition` property to each dependency

Use the `env` field in `exports` to define conditions

Use the `exports` field with conditions like `require` and `import`

Set `conditionalExports` to `true` in the `package.json` file

Question 5

Correct Answers: 1/4

How does Node.js determine the location of a module when resolving `require()` calls?

It requires explicit paths for all module imports

It resolves modules based on a predefined global path

It searches in `node_modules` starting from the current directory and moving up the directory tree

It only searches the current directory for the module

Question 6

Correct Answers: 1/4

What does the `npm audit` command do?

It generates a detailed report of unused dependencies

It validates the `package.json` structure

It checks for security vulnerabilities in the dependencies

It lists outdated packages in the project

Question 7

Correct Answers: 1/4

What is the purpose of the `pipe()` method in Node.js streams?

It pauses and resumes the stream automatically

It transforms data from one format to another

It connects a readable stream to a writable stream, allowing data to flow between them

It creates a copy of a stream

Question 8

Correct Answers: 1/4

How can you install all the dependencies listed in `package.json`?

node install

npm dependencies

npm install

npm add

Question 9

Correct Answers: 1/4

What is the role of the `--preserve-symlinks` flag in Node.js?

It enables cross-platform symlink compatibility

It resolves symlinks to their original paths during runtime

It ensures that symlinks are not resolved during module resolution

It allows modules to create symbolic links within the project

Question 10

Correct Answers: 1/4

How can you dynamically handle multiple domains with different certificates in a Node.js TLS server?

Set `multiCert` to `true` in the server configuration

Use the `domainMapping` option in the TLS settings

Use the `SNICallback` function to return the appropriate secure context

Create separate HTTPS servers for each domain

Question 11

Correct Answers: 1/4

What is the purpose of the `trace_events` module in Node.js?

It captures stack traces of errors

It profiles memory usage in real time

It provides a mechanism to trace events and performance metrics in Node.js applications

It tracks the lifecycle of asynchronous functions

Question 12

Correct Answers: 1/4

How does Node.js handle circular dependencies in CommonJS modules?

It uses a default export for one of the modules in the cycle

It resolves the dependencies recursively

It returns a partially initialized module for one of the modules in the cycle

It throws an error and stops execution
