Which statements are true? (Select three.)

A.
In OAM F4 Flow cells, the VCI defines if segment or end-to-end.

B.
In OAM F5 Flow cells, the VCI defines if segment or end-to-end.

C.
VCI = 3 is used for segment OAM F4 and VCI = 4 is used for end-to-end OAM F4.

D.
VCI = 4 is used for segment OAM F4 and VCI = 3 is used for end-to-end OAM F4.

E.
The OAM Type is included in the ATM Cell payload.

Explanation:
When you create a PVP, the router creates two PVCs for end-to-end loopback and segment loopback operations, administration and maintenance (OAM) cells. OAM cells at the VP level use the same VPI value as the user cells of the PVP and use defined or “well-known” VCI values. These VCI values are 3 for segment OAM F4 flow and 4 for end-to-end OAM F4 flow.
