Version: 12.0
Question: 21

Which IP addresses are valid for hosts belonging to the subnet? (Choose three.)


Answer: A, C, D

All IP address in IP ranges between: and are valid as shown below
Address: 00001010.00000001.1010 0000.00000000
Netmask: = 20 11111111.11111111.1111 0000.00000000
Wildcard: 00000000.00000000.0000 1111.11111111
Which implies that:
Network: 00001010.00000001.1010 0000.00000000
HostMin: 00001010.00000001.1010 0000.00000001
HostMax: 00001010.00000001.1010 1111.11111110
Broadcast: 00001010.00000001.1010 1111.11111111

Question: 22

Given an IP address of, what is the subnet address?


Answer: C

248 mask uses 5 bits (1111 1000)
.42 IP in binary is (0010 1010)
The base subnet therefore is the lowest binary value that can be written without changing the output of an AND operation of the subnet mask and IP…
1111 1000 AND
0010 1010 equals
0010 1000 – which is .40
/24 is standard class C mask.
Adding the 5 bits from the .248 mask gives /29

Which OSI layer header contains the address of a destination host that is on another network?

A. application
B. session
C. transport
D. network
E. data link
F. physical

Answer: D

Only network address contains this information. To transmit the packets the sender uses network address and datalink address. But the layer 2 address represents just the address of the next hop device on the way to the sender. It is changed on each hop. Network address remains the same.

Question: 24

Which layer of the TCP/IP stack combines the OSI model physical and data link layers?

A. Internet layer
B. transport layer
C. application layer
D. network access layer

Answer: D

The Internet Protocol Suite, TCP/IP, is a suite of protocols used for communication over the internet. The TCP/ IP model was created after the OSI 7 layer model for two major reasons. First, the foundation of the Internet was built using the TCP/IP suite and through the spread of the World Wide Web and Internet, TCP/IP has been preferred. Second, a project researched by the Department of Defense (DOD) consisted of creating the TCP/IP protocols. The DOD’s goal was to bring international standards which could not be met by the OSI model.
Since the DOD was the largest software consumer and they preferred the TCP/IP suite, most vendors used this model rather than the OSI. Below is a side by side comparison of the TCP/IP and OSI models.

Question: 25

Which protocol uses a connection-oriented service to deliver files between end systems?


Answer: C

TCP is an example of a connection-oriented protocol. It requires a logical connection to be established between the two processes before data is exchanged. The connection must be maintained during the entire time that communication is taking place, then released afterwards. The process is much like a telephone call, where a virtual circuit is established–the caller must know the person’s telephone number and the phone must be answered–before the message can be delivered.
TCP/IP is also a connection-oriented transport with orderly release. With orderly release, any data remaining in the buffer is sent before the connection is terminated. The release is accomplished in a three-way handshake between client and server processes. The connection-oriented protocols in the OSI protocol suite, on the other hand, do not support orderly release. Applications perform any handshake necessary for ensuring orderly release.
Examples of services that use connection-oriented transport services are telnet, rlogin, and ftp.

Question: 26

Refer to the exhibit.

If the hubs in the graphic were replaced by switches, what would be virtually eliminated?

A. broadcast domains
B. repeater domains
C. Ethernet collisions
D. signal amplification
E. Ethernet broadcasts

Answer: C

Modern wired networks use a network switch to eliminate collisions. By connecting each device directly to a port on the switch, either each port on a switch becomes its own collision domain (in the case of half duplex links) or the possibility of collisions is eliminated entirely in the case of full duplex links.
