SWA and 5WB are connected through two physical Ethernet links. SWA has the following interface configurations:

The two links are aggregated. Assume that the configuration on SWB is correct. Given this information, which of the following statements are true?

• A.GigabitEthernet1/0/1 and GigabitEthernet/0/2 can be added to the same LAG only after the configuration of GigabitEthernet/0/2 is changed to be the same as that of GigabitEthernet1/0/1.
• B.After link aggregation is configured on SWA and SWB, if MSTP is enabled on them, GigabitEthernet1/0/1 and GigabitEthernet1/0/2 enter the Forwarding state in MSTP.
• C.GigabitEthernet1/0/1 and GigabitEthernet1/0/2 can be added to the same LAG without changing the current configurations.
• D.GigabitEthernet1/0/1 and GigabitEthernet/0/2 cannot be added to the same LAG because the allowed VLANs are different.
