You need to launch a Linux EC2 instance in AWS. Which of the following steps can be used to ensure secure authentication to the EC2 instance from a windows machine? (Select TWO.)

Answer options:

A.Ensure to create a strong password for logging into the EC2 Instance.
B.Create a key pair using PuTTYgen.
C.Use the private key to log into the instance.
D.Ensure the password is passed securely using SSL.

Answer – B and C
The AWS Documentation mentions the following.
You can use Amazon EC2 to create your key pair. Alternatively, you could use a third-party tool and then import the public key to Amazon EC2. Each key pair requires a name. Be sure to choose a name that is easy to remember. Amazon EC2 associates the public key with the name that you specify as the key name.
Amazon EC2 stores the public key only, and you store the private key. Anyone who possesses your private key can decrypt your login information. So it`s important that you store your private keys in a secure place.
Options A and D are incorrect since you should use key pairs for secure access to EC2 Instances.
