1. Using the header and trailer format, what is the order of PDU encapsulation? 3.3.1.3
Frame header, network header, transport header, data, frame tailor.
2. What is the purpose of using the keystrokes (Ctrl-Shift-6 key) after issuing the ping command? 2.1.4
Ony for Cli use and it helps you end the ping.
3. Why is a converged network of importance?1.3.1
Converged networks are capable of delivering voice, video streams, text, and graphics between many different types of devices over the same communication.
4. In the network below, which area would most likely be an extranet, and which would be an Intranet? 1.2.3 a- Exatrnet; b-Extranet; c- Intrranet; and d- Intranet
5. What is the function of the physical layer of the OSI model? 4.1.2
It lets the user send transport the data across the network.
6. Why do they twist wire pairs together in copper cables? 4.2.1
The twisting of wires helps protect against signal interference from other wires
7. When the destination MAC address of a received frame is not in the MAC table, what will a Layer 2 switch do? 5.3.1 The switch send the frame to all the ports except the one it recived it from.
8. What is tested using the Loopback command ping 127.0.0.1? 2.3.3
It determines if the network on the local host is functioning on the right network.
9. What is the auto-MDIX feature on a switch used for? 5.3.1
It is used to enable crosove conectivity between the switch and other devices.
10. In an IPv4 packet header, which field will usually stay the same during its transmission? 6.1.3
Version is always set to 0100.
11. What is the default order a router will search for startup configuration info? 6.3.2
NVRAM, TFTP and setup mode.
12. How does the router choose the path to the destination network when there are multiple routes available? 6.2.2
It uses the address of the gateway devices to forward the information to the destination.
13. List the 3 functions or
