The network administrator wishes to forward data over an Eth-trunk, however associated member interfaces operate at different rates. In terms of the resulting behavior, which of the following is true?
A.
The two switches will not be able to communicate.
B.
The higher rate member interfaces may incur packet loss.
C.
The Eth-Trunk will work normally.
D.
The lower rate member interfaces may incur packet loss.
Yeah a bit confusing, R&S v2.5 intermediate book states that "when member interfaces have different rates, the interface with lower rates may become congested and packet loss may occur." But all public support pages say that you can't bundle interfaces with different rates. Maybe this means that you can bundle 2x Gigabit Ethernets to Eth-trunk and squeeze one of them to speed 100 and this causes the congestion. If this is the case, then D is correct. Especially when interfaces have already associated to eth-trunk.
A correct answer is A.

"In versions earlier than V200R011C10, only interfaces with the same rate can join an Eth-Trunk. For example, GE electrical interfaces and GE optical interfaces can be added to the same Eth-Trunk. In V200R011C10 and later versions, after the mixed-rate link enable command is run, interfaces with different rates can be added to the same Eth-Trunk."
