Which of the following operations does SW1

perform after receiving a data frame from PC1 when PC1 is connected to GE1/0/2 of SW1?

SW1 saves the mapping between the MAC address of PC1 and GE1/0/1, and also keeps the mapping between the MAC address of PC1 and GE1/0/2.

SW1 saves the mapping between the MAC address of PC1 and GE1/0/2 and deletes the mapping between the MAC address of PC1 and GE1/0/1.

The data frame processed inside SW1 does not carry any VLAN tag.

SW1 removes the VLAN 10 tag from the data frame before forwarding it from GE1/0/2 to PC2.

10. On a switched network where STP is enabled on all devices, when a downstream device detects a topology change, it continuously sends configuration BPDUs to the upstream device until the root bridge is informed of the topology change.
