Cut-through frame forwarding ensures that invalid frames are always dropped.

Frame forwarding decisions are based on MAC address and port mappings in the CAM table.

SW1 floods the frame on all ports on the switch, excluding the interconnected port to switch SW2 and the port through which the frame entered the switch.

SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.

SW1 drops the frame because it does not know the destination MAC address.

15. An administrator is trying to remove configurations from a switch. After using the command erase startup-config and reloading the switch, the administrator finds that VLANs 10 and 100 still exist on the switch. Why were these VLANs not removed?

These VLANs cannot be deleted unless the switch is in VTP client mode.

These VLANs are default VLANs that cannot be removed.

These VLANs can only be removed from the switch by using the no vlan 10 and no vlan 100 commands.

Because these VLANs are stored in a file that is called vlan.dat that is located in flash memory, this file must be manually deleted.

89. A network engineer is troubleshooting a newly deployed wireless network that is using the latest 802.11 standards. When users access high bandwidth services such as streaming video, the wireless network performance is poor. To improve performance the network engineer decides to configure a 5 Ghz frequency band SSID and train users to use that SSID for streaming media services. Why might this solution improve the wireless network performance for that type of service?

Requiring the users to switch to the 5 GHz band for streaming media is inconvenient and will result in fewer users accessing these services.

The 5 GHz band has more channels and is less crowded than the 2.4 GHz band, which makes it more suited to streaming multimedia.

The 5 GHz band has a greater range and is therefore likely to be interference-free.

The only users that can switch to the 5 GHz band will be those with the latest wireless NICs, which will reduce usage.

The 5 GHz band has more channels and is less crowded than the 2.4 GHz band, which makes it more suited to streaming multimedia.

92. After a host has generated an IPv6 address by using the DHCPv6 or SLAAC process, how does the host verify that the address is unique and therefore usable?

The host sends an ICMPv6 neighbor solicitation message to the DHCP or SLAAC-learned address and if no neighbor advertisement is returned, the address is considered unique.

The host checks the local neighbor cache for the learned address and if the address is not cached, it it considered unique.

The host sends an ARP broadcast to the local link and if no hosts send a reply, the address is considered unique.
