You want to launch an EC2 Instance with your own key pair in AWS. After you generate the key pair through OpenSSL, how would you configure the key pair in EC2?

Answer options:

A.In AWS Console, use "Create key pair" to import the public key to the EC2 service.
B.In AWS Console, use "Import key pair" to import the private key to the EC2 service.
C.In AWS Console, use "Import key pair" to import the public key to the EC2 service.
D.Use AWS CLI create-key-pair to import the public key to the EC2 service.

Answer – C
You could use a third-party tool such as OpenSSL to generate a key pair and then import the public key to Amazon EC2. 
Option A is incorrect because with "Create key pair", you cannot create your own key pair using OpenSSL.
Option B is incorrect because you should import the public key with "Import key pair".
Option C is CORRECT because "Import key pair" allows you to import your own public key to EC2.
Option D is incorrect because the correct AWS CLI should be import-key-pair instead of create-key-pair.
