Answer options

• A. Encapsulating security payload
• B. Authentication host mode
• C. Security tag
• D. Authentication header
• E. Message authentication code

Correct answer: C, E

Explanation

The correct answers are C and E because MACsec adds a Security tag and a Message authentication code to the Ethernet frame for enhanced security. Options A, B, and D are not applicable as they do not represent additional fields in the context of MACsec.
