The SWA and SWB are connected by two physical Ethernet links.
The SWA has the following interface configurations:
[SWA]interface GigabitEthernet 1/0/1
[SWA-GigabitEthernet 1/0/1] port link-type trunk
[SWA-GigabitEthernet 1/0/1] port trunk allow-pass vlan 1 0 100
[SWA]interface GigabitEthernet 1/0/2
131 / 144 The safer , easier way to help you pass any IT exams.
[SWA-GigabitEthernet 1/0/2] port link-type trunk
[SWA-GigabitEthernet 1/0/2] port trunk allow-pass vlan 1 10
These two links are aggregated
Assume that the configuration on the SMB is correct.
Which of the following statements are correct in view of this information? (Multiple Choice)

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