Which two fields are characteristics of IEEE 802.1AE frame? (Choose two.)
A. destination MAC address
B. source MAC address
C. 802.1AE header in EtherType
D. security group tag in EtherType
E. integrity check value
F. CRC/FCS
Which two fields are characteristics of IEEE 802.1AE frame?
CE is the right answer.
The new SecTAG field, which is 16 octets long is itself shown as “802.1AE Header” in the (MacSec Header) frame.
“While MACsec is based on the standard Ethernet frame format, an additional 16-byte MACsec Security Tag or
SecTAG was included, as well as a 16-byte Integrity Check Value (ICV) at the end of the frame. ”
D and E
Can anyone confirm C and E ?

Explanation: MACsec frame format, which is similar to the Ethernet frame, but includes additional
fields: Security Tag, which is an extension of the EtherType. Message authentication code (ICV)
802.1AE = MacSec
