AWS, JavaScript, React - Deploy Web Apps on the Cloud - SSH Key Pair Authentication on MacOS

This tutorial demonstrates how to generate an SSH key pair on a Mac or Linux system and connect to a remote instance using Terminal. It covers launching Terminal, generating a secure SSH key pair, verifying the keys, copying the public key to a server, and establishing a secure connection using SSH key authentication.

What is the first step to start generating an SSH key pair on a Mac or Linux system?

• Access System Preferences

• Open Safari

• Launch Terminal

• Open Finder

Which command is used to generate an SSH key pair with a high degree of security?

• ssh-keygen -b 2048

• ssh-keygen -t rsa

• ssh-keygen -b 4096

• ssh-keygen -t dsa

What is the purpose of setting a passphrase for the SSH key pair?

• To speed up the key generation process

• To increase the key size

• To add an extra layer of security

• To change the default key names

How can you confirm that the SSH key pair has been successfully generated?

• By restarting the computer

• By listing the contents of the SSH directory

• By checking the system logs

• By opening the key files in a text editor

Which command is used to copy the public key to a remote instance?

• rsync

• ssh-copy-id

• scp

• ftp

What should you do if prompted to confirm the connection to the server during the installation process?

• Close the Terminal

• Type 'yes' and press Enter

• Type 'no' and press Enter

• Restart the Terminal

What indicates that SSH keypair authentication is working correctly when reconnecting to the instance?
