What happens to the member ports of a VLAN when the VLAN is deleted?
Perrine. J
1.
They become inactive.
2.
They default back to the management VLAN.
3.
They automatically become a part of VLAN1.
4.
They must be assigned to another VLAN before the original VLAN can
be deleted.
5.
They remain a part of that VLAN until the switch is rebooted. They then
become members of the management VLAN.

How does a bridge handle the frames that it receives? (Choose three.)
Perrine. J
1.
If the source is unknown, the source port is shutdown.
2.

gateway.
5.

ports in the broadcast domain, except for the source port.
6.
If the destination of the frame is on the same segment as the source, a
bridge will not forward the frame.
