Which two statements about the C-bit and PW type are true? (Choose two.)
A.
The C-bit is 1 byte and the PW type is 15 bytes.
B.
The PW type indicates the type of pseudowire.
C.
The C-bit is 3 bits and the PW type is 10 bits.
D.
The C-bit set to 1 indicates a control word is present.
E.
The PW type indicates the encryption type.
The control word carries generic and Layer 2 payload-specific information. If the C-bit is set to 1,
the advertising PE expects the control word to be present in every pseudowire packet on the
pseudowire that is being signaled. If the C-bit is set to 0, no control word is expected to be
present.
Pseudowire Type—PW Type is a 15-bit field that represents the type of pseudowire.
