Which three statements are true about the operation of a full-duplex Ethernet network?
There are no collisions in full-duplex mode.
A dedicated switch port is required for each full-duplex node.
Ethernet hub ports are preconfigured for full-duplex mode.
In a full-duplex environment, the host network card must check for the availability of the network media before transmitting.
The host network card and the switch port must be capable of operating in full-duplex mode.
Options
A. 1, 2, and 5
B. 2 and 4
C. 2, 3 and 4
D. 5 only
Correct Answer
1, 2, and 5
Explanation
Full-duplex means you are using both wire pairs simultaneously to send and receive data. You must have a dedicated switch port for each node, which means you will not have collisions. Both the host network card and the switch port must be capable and set to work in full-duplex mode.

1. How many collision domains are created when you segment a network with a 12-port switch?
You need 5 subnets, each with at least 16 hosts. The mask 255.255.255.240 provides 16 subnets with 14 hosts-this will not work. The mask 255.255.255.224 provides 8 subnets, each with 30 hosts. This is the best answer.
5. Which command is required for connectivity in a Frame Relay network if Inverse ARP is not operational?
If you have a router in your Frame Relay network that does not support IARP, you must create Frame Relay maps on your router, which provide known DLCI-to-IP address mappings.
6. What VTP mode allows you to change VLAN information on the switch?
A CIDR address of /19 is 255.255.224.0. This is a Class B address, so that is only 3 subnet bits, but it provides 13 host bits, or 8 subnets, each with 8,190 hosts.
8. Which command will allow you to see real-time translations on your router?
Any secondary route to a remote network is considered a feasible successor, and those routes are only found in the topology table and used as backup routes in case of primary route failure. You can see the topology table with the
show ip eigrp topology command.
