The tutorial emphasizes best practices, such as closing connections and ensuring network access. It also provides a brief introduction to Node.js and its use with MongoDB.

What is the primary purpose of using drivers when connecting to MongoDB?

• To enhance the speed of data retrieval

• To simplify the connection process between code and MongoDB

• To enable offline data access

• To provide additional security layers

Which command is used to install the MongoDB driver for Node.js?

• npm install mongo-driver

• npm install mongodb-driver

• npm install mongodb

• npm install node-mongo

Why is an async function used when connecting to MongoDB?

• To allow for synchronous data processing

• To improve the performance of the application

• To ensure the connection process is completed before proceeding

• To handle multiple connections simultaneously

What is the role of the URI in connecting to MongoDB?

• It specifies the database to connect to

• It contains the connection string for the MongoDB cluster

• It defines the user permissions

• It sets the timeout for the connection

What is the purpose of the try-catch block in the connection script?

• To optimize the connection speed

• To handle errors during the connection process

• To manage user authentication

• To log successful connections

What does the 'finally' block ensure in the connection script?

• The connection is retried if it fails

• The connection is kept open for future use

• The connection is closed after the operation

• The connection is logged for auditing

What should you check if you encounter an exception during the connection?

• Update the MongoDB driver to the latest version

• Ensure the MongoDB server is running

• Verify user access permissions and network settings

• Check the syntax of the connection script
