| Question ID 16019 | What does a Layer 2 switch use to decide where to forward a received frame?
|
| Option A | source MAC address
|
| Option B | source IP address
|
| Option C | source switch port
|
| Option D | destination IP address
|
| Option E | destination port address
|
| Option F | destination MAC address
|
| Correct Answer | F |
Explanation Explanation: When a frame is received, the switch looks at the destination hardware address and finds the interface if it is in its MAC address table. If the address is unknown, the frame is broadcast on all interfaces except the one it was received on.
| Question ID 16020 | Refer to the exhibit.
Which two statements are true of the interfaces on Switch1? (Choose two.)
|
| Option A | Multiple devices are connected directly to FastEthernet0/1.
|
| Option B | A hub is connected directly to FastEthernet0/5.
|
| Option C | FastEthernet0/1 is connected to a host with multiple network interface cards.
|
| Option D | FastEthernet0/5 has statically assigned MAC addresses.
|
| Option E | FastEthernet0/1 is configured as a trunk link.
|
| Option F | Interface FastEthernet0/2 has been disabled.
|
| Correct Answer | B,E |
Explanation Explanation: Carefully observe the information given after command show. Fa0/1 is connected to Switch2, seven MAC addresses correspond to Fa0/1, and these MAC are in different VLAN. From this we know that Fa0/1 is the trunk interface. From the information given by show cdp neighbors we find that there is no Fa0/5 in CDP neighbor. However, F0/5 corresponds to two MAC addresses in the same VLAN. Thus we know that Fa0/5 is connected to a Hub. Based on the output shown, there are multiple MAC addresses from different VLANs attached to the FastEthernet 0/1 interface. Only trunks are able to pass information from devices in multiple VLANs.
