Referring to the exhibit, a customer noticed that the 802.1Q-tunneled packets received on SwitchB
are being dropped.
What is causing this problem?
A.
There is an ether-type mismatch on SwitchA and SwitchB.
B.
Customer VLANs are not configured on SwitchB.
C.
The SwitchB interface connecting to SwitchA is not a trunk port.
D.
Customer VLANs are mismatched on both switches.
On switch B why there is not any ports in vlan 4001?
Its ge-0/0/10 port is in trunk mode?
How can it work, because the switch A ge-0/0/10 port is int access mode?
this is confusing
anyway, i think juniper default ethertype is 0x8100 or 0x88A8 for QinQ
search for 802.1ad and read about ethertypes
Vlan 4001 here is being used as carrier’s transport VLAN, inside of it customer VLANs are being tunneled. Answer seems to be correct as Juniper’s default ethertype is 0x8100.
By the way, part of that new 80Q JN0-647 dumps for your reference:
