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.
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 are default VLANs that cannot be removed. These VLANs cannot be deleted unless the switch is in VTP client mode. 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.

Compared with dynamic routes, what are two advantages of using static routes on a router? (Choose two.) They improve network security. They use fewer router resources. They improve the efficiency of discovering neighboring networks. They take less time to converge when the network topology changes. They automatically switch the path to the destination network when the topology changes.

It uses a single network address to send multiple static routes to one destination address. It identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route It is configured with a higher administrative distance than the original dynamic routing protocol has.
provides access to the rest of the network through switching, routing, and network access policies
What is a characteristic of the distribution layer in the three layer hierarchical model? acts as the backbone for the network, aggregating and distributing network traffic throughout the campus provides access to the rest of the network through switching, routing, and network access policies distributes access to end users represents the network edge
There is no end-to-end addressing.
What is a disadvantage of NAT? The internal hosts have to use a single public IPv4 address for external communication. There is no end-to-end addressing. The costs of readdressing hosts can be significant for a publicly addressed network. The router does not need to alter the checksum of the IPv4 packets.

Forward the frame out all ports except the port where the frame is received.
What will a Cisco LAN switch do if it receives an incoming frame and the destination MAC address is not listed in the MAC address table? Drop the frame. Send the frame to the default gateway address. Use ARP to resolve the port that is related to the frame. Forward the frame out all ports except the port where the frame is received.

What will be the result of adding the command ip dhcp excluded-address 172.16.4.1 172.16.4.5 to the configuration of a local router that has been configured as a DHCP server? Traffic that is destined for 172.16.4.1 and 172.16.4.5 will be dropped by the router. Traffic will not be routed from clients with addresses between 172.16.4.1 and 172.16.4.5. The DHCP server function of the router will not issue the addresses from 172.16.4.1 through 172.16.4.5 inclusive. The router will ignore all traffic that comes from the DHCP servers with addresses 172.16.4.1 and 172.16.4.5.

Frame forwarding decisions are based on MAC address and port mappings in the CAM table.
Which statement correctly describes how a LAN switch forwards frames that it receives? Only frames with a broadcast destination address are forwarded out all active switch ports. Unicast frames are always forwarded regardless of the destination MAC address. Frame forwarding decisions are based on MAC address and port mappings in the CAM table. Cut-through frame forwarding ensures that invalid frames are always dropped.
