A. It does not contain the appropriate Data Link layer information required by routers.
B. It uses advanced Transport layer services to move across the Internet and avoids the
routing overhead required by the more primitive networking protocols.
C. It defines Physical layer network addresses for internal routing.
D. It does not specify the Network layer addresses required by routers.
D - Non-routable protocols do not contain Network layer information, which means
that routers cannot interpret their addresses. Routers are not concerned with Data Link layer
information. Transport layer protocols require the services of a routing protocol to move data
across an internetwork. Addresses are not definable at the Physical layer because data is in the
form of a raw bit stream.
Protocols can be categorized as follows:
> Connection Oriented Protocol - A protocol that relies on establishment of a connection
between two computers. Connection oriented protocols are considered to be reliable
protocols since there is an integrity check to be sure the transmitted data was received.
> Connectionless Protocol - Do not rely on a connection, therefore Considered to be an
> Routable Protocol - The protocol can be sent through a network router.
> Non-routable Protocol - Cannot be sent through a network router.

4. What is the binary network ID of the loopback IP address?
D - The Loopback address is a special IP address (127.0.0.1) that is designated for
the software loopback interface of a machine. The loopback interface has no hardware
associated with it, and it is not physically connected to a network. The 127.0.0.1 IP address is
otherwise known as 'localhost'. At the command prompt type C:\>
localhost OR C:\>
127.0.0.1 . You will come up with exactly the same results! 127 represents the Network ID and
is expressed as 1111111 in binary code.

5. You are the LAN administrator for your company. You have couple Windows 2000 Professional
clients that dial in via PPP to the company network?s RAS server. You want the remote clients
to be assigned dynamic IP addresses. You reserve a pool of class B addresses for these clients.
Upon connecting, you find that the Windows 2000 computers are using a subnet mask of all
255s. What should you do?
A. Run ipconfig with the /release and /renew switch on the client
B. Run ipconfig with the /renew_all switch on the client
C. Run winipcfg on the client
D. Increase the lease time for this address pool
E. Reconfigure the DHCP scope options
F. Do nothing. This is normal
G. None of the choices.
