Answer: Create new Direct Connect connections while requesting MACsec ports., Create a MACsec Connectivity Association Key Name (CKN) and Connectivity Association Key (CAK) pair. Associate the pair with each new connection., Update the on-premises routers to use MACsec and the shared Connectivity Association Key Name (CKN) and Connectivity Association Key (CAK) pair.

To ensure all network communications are encrypted in transit when migrating internet VPN connections to dedicated AWS Direct Connect connections, the company needs to implement MACsec (Media Access Control Security) for encryption. MACsec provides point-to-point encryption on the physical link between the customer's network and AWS. The correct steps to achieve this are: A. Create new Direct Connect connections while requesting MACsec ports, which ensures the physical connection supports MACsec encryption. B. Create a MACsec Connectivity Association Key Name (CKN) and Connectivity Association Key (CAK) pair and associate the pair with each new connection, which is necessary for the MACsec encryption process. C. Update the on-premises routers to use MACsec and the shared Connectivity Association Key Name (CKN) and Connectivity Association Key (CAK) pair, ensuring that the encryption is applied on the customer's side as well. Options D, E, and F involve IPsec, which is not required for Direct Connect connections when MACsec is used for encryption.
