Pick the 4 valid ATM Cell Header fields:

A.
GFC-4 bits of generic flow control

B.
Forward-explicit congestion notification(FECN)

C.
VCI-16 bits of virtual channel identifier

D.
CLP-1 bit of congestion loss

E.
HEC-8 bit of header error control

F.
ATM Discard Eligibility(DE) bit

Explanation:
The ATM cell header consists of the following fields: generic flow control (GFC), virtual path

identifier (VPI), virtual channel identifier (VCI), payload type (PT), cell loss priority (CLP) and
header error control (HEC).
