Which two frames can be configured on an Ethernet flow point? (Choose two.)
A. of a specific VLAN
B. with different type of service values
C. with identical type of service value
D. with different class of service values
E. with no tags
Which two frames can be configured on an Ethernet flow point?
When it comes to CoS. It has to be “Frames with identical Class of Service (CoS) values”
EFPs can be configured on any Layer 2 traffic port; however, they are usually configured on UNI ports. The following parameters (matching criteria) can be configured on the EFP:
Frames of a specific VLAN, a VLAN range, or a list of VLANs (100-150 or 100,103,110)
Frames with no tags (untagged)
Frames with identical double-tags (VLAN tags) as specified

In that case A,E are OK

Identifying Frames of an EFP
The EFP identifies frames belonging to a particular flow on a given port, independent of their Ethernet encapsulation. An EFP can flexibly map frames into a flow or EFP based on the fields in the frame header.
The frames can be matched to an EFP using:
• VLAN tag or tags
• MAC address (source address, destination address, or both)
• 802.1p CoS bits
• Logical conjunction of two or more of the above: VLAN, MAC, and CoS
• Default match (that is, any other traffic that has not matched a more specific EFP)
• Protocol ethertype
