To connect to a router or switch console port, you would use an RJ45 UTP rolled cable.

The application layer is responsible for finding the network resources broadcast from a server and adding flow control and error control (if the application developer chooses)

Answer : A

Explanation:

Remember,  most network is still build on IPv4 structure and IPv4 is not going away in a hurry… one of the many techniques used to migrate to IPv6 is Tunneling.

Tunneling is a method that a network built on IPv4 structure can be configured to traffic IPv6 packet simultaneously.

Answer and Explanation:

Because the destination address is on a different subnet from the switch, the packet will be forwarded to its default gateway. To verify the default gateway of this switch, use the show running-config command

From the output above, we can see that its default-gateway is 192.168.1.254. Which can be said to be a layer 3 device (router); in this case, the VLAN-R1 router. You can use the show cdp neighbor detail command verify further.

From the output above, you can confirm that the switch's default gateway is VLAN-R1 router (with the IP address of 192.168.1.254).The interface FastEthernet0/3 shows that the switch is directly connected to VLAN-R1 router through the switchport Fa0/3. To verify the MAC address associated this interface is interface, you use the show mac-address-table command:

Looking closely at the table above, you will discorver that the corresponding MAC address is 000a.b7e9.8360. Although there are some entries on port Fa0/3 with different Vlans ,but they have the same MAC address.

RIPv1 and RIPv2 only use the lowest hop count to determine the best path to a remote network.

Static routes have an administrative distance of 1 by default. Unless you change this, a static route will always be used over any other dynamically learned route. EIGRP has an administrative distance of 90, and RIP has an administrative distance of 120, by default

EIGRPv6's multicast address stayed very near the same. In IPv4 it was 224.0.0.10; now it is FF02::A (A = 10 in decimal notation)

Clocking on a serial interface is always provided by the CSU/DSU (DCE device). However, if you do not have a CSU/DSU in your non-production test environment, then you need to supply clocking with the clock rate command on the serial interface of the router with the DCE cable attached.
