When the Data Link layer performs encapsulation, it adds control information to the payload in the form of header flelds. Which of the following are header fields added by the Data Link layer during encapsulation? (Select three.) TTL (Time to Live) Destination hardware address Window size Encryption type Sequence number Checksum for basic error checking Source hardware address

The Data Link layer adds the following header fields during encapsulation:<br /><br />1. Destination hardware address<br />2. Source hardware address<br />3. Checksum for basic error checking<br /><br />TTL (Time to Live) is a field added by the Network layer, not the Data Link layer. Window size and encryption type are fields added by the Transport layer. Sequence number is also a field added by the Transport layer.
