Introduce a Layer 3 device or a switch with Layer 3 capability in the topology
• Apply IP addresses that are in the same subnet to the interfaces used to connect SW1 and SW2.
• A new RSA key pair is created.
• The switch defaults to allowing Telnet connections only
• The switch is no longer able to make SSH connections as an SSH client

• forward the frame out Interface3
• discard the frame
• forward the frame out all interfaces

• It eliminates Layer 2 loops in network topologies.
• It eliminates the need for redundant physical paths in network topologies
• It can only be used in networks in which Layer 2 switching is in use.
• It can only be used in networks where both routers and switches are used together
• It can only be used in networks where routers are installed.

• SW1 drops the traffic because it is untagged.
• SW1 leaves the traffic untagged and forwards it over the trunk.
• SW1 tags the traffic with the lowest VLAN ID value and forwards it over the trunk link.
• SW1 encapsulates the traffic with 802.1Q encapsulation and forwards it over the trunk link.
• A new VLAN can be added to Switch1 and that information will be added only to Switch2
• A new VLAN can be added to Switch1 and that information will be added to Switch2 and Switch4.
• An existing VLAN can be deleted from Switch4 and that VLAN will be deleted from Switch1 and Switch2.
• An existing VLAN can be deleted from Switch2 and that VLAN will be deleted from Switch1 and Switch4.
• A new VLAN can be added to Switch4 and that information will be added to Switch1, Switch2, and Switch3.
• A new VLAN can be added to Switch3 and that information will be added to Switch1, Switch2, and Switch4.

• VLAN 10 and VLAN 20
• VLAN 1, VLAN 10, and VLAN 20
• VLAN 1, VLAN 1002 through 1005
• VLAN 1, VLAN 10, VLAN 20, VLAN 1002 through 1005
• The switch will not allow any other device to connect to port Fa0/15.
• Traffic destined for MAC address 0000.c123.5432 will be forwarded to Fa0/15.
• This entry will be removed and refreshed every 300 seconds to keep it in the table.
• The switch learned this MAC address from the source address in a frame received on Fa0/15.
• When processing a frame, the switch does not have to perform a lookup to determine the final destination port.
• requires the use of subinterfaces on the router
• requires an access link between the router and Layer 2 switch
• more cost-efficient and scalable than using multiple physical interfaces
• requires each subinterface to be configured with the no shutdown command
• can impact performance if many VLANs compete for bandwidth on a single router interface
• makes troubleshooting the inter-VLAN routing configuration much less complex than when using multiple physical interfaces
• The router will forward the packet out interface FastEthernet 0/1.1.
• The router will forward the packet out interface FastEthernet 0/1.2.
• The router will forward the packet out interface FastEthernet 0/1.3.
• The router will forward the packet out interface FastEthernet 0/1.2 and interface FastEthernet 0/1.3.
• The router will ignore the packet because the source and destination are on the same broadcast domain.
• The router will drop the packet since no network that includes the source address is attached to the router.
