Referring to the exhibit, a customer notices that MSTP is not converging on MSTI 2. To
troubleshoot the problem, the customer captured traffic on the link (xe-0/0/0) of SwitchA
connecting to SwitchB.
Which two situations would cause the problem? (Choose two.)

A.
MSTI 1 and MSTI 2 are part of the same MSTP region.

B.
The bridge priority value of the MSTI 2 is the same on SwitchA and SwitchB.

C.
VLAN 30 and VLAN 40 are not configured on SwitchA.

D.
VLAN 30 and VLAN 40 are not members of trunk link xe-0/0/0 on SwitchA.
