Correct Answer: A

A key pair is a set of public & private keys which are security credentials used to connect to Amazon EC2 instances. Following are the ways to create key pair for connecting to an Amazon EC2 instance,

1. Create a Key Pair using Amazon EC2 instance: Key pairs can be created using console, AWS CLI or PowerShell. Public Key is stored in Amazon EC2 instance. Customers need to download & save private keys securely which will be used to connect to Amazon EC2 instances.
2. Create a Key Pair using third-party tools: Key pairs can be generated using third-party tools. Private keys generated by this tool need to be stored securely, while public keys need to be imported in Amazon EC2 instances using console, AWS CLI or PowerShell.

• Option B is incorrect as there is no need to import private keys into Amazon EC2 instances. Amazon EC2 instance stores Public key. Private Key needs to be securely stored by the customer.
• Option C is incorrect as when a key is generated using an Amazon EC2 instance, no need to import the public key into the Amazon EC2 instance. 
• Option D is incorrect as  there is no need to import private keys into Amazon EC2 instances. Amazon EC2 instance stores only Public key. Private Key needs to be securely stored by the customer.
