CCNA (V.31) Semester-1- Question - Answers- Paper 9


1 What steps must occur for devices to communicate between different physical network segments? (Choose two.)

learning the IP address of the source device
* obtaining the MAC address of the intermediate device
* transferring the data packets from one network segment to another to reach the destination host
obtaining the IP address of the local host



2 What should a system administrator consider when assigning an IP address to a network server? (Choose two.)

Servers should have addresses assigned dynamically through a DHCP.
* Servers with a dynamically assigned IP address would be difficult to locate on a network.
Servers with periodically changed IP addresses have little effect on a network.
* Servers should have IP addresses assigned statically by a network system administrator.

3 Several solutions have been developed to expand the number of IP addresses available for public use. Which technologies are solutions? (Choose three.)

DHCP
* classless interdomain routing
a new 64 bit addressing scheme
* Network Address Translation
* IPv6
IPv5

4 Which criteria identify a Class B address? (Choose two.)

decimal number in first octet between 127-191
decimal number in first octect between 128-192
* decimal number in first octect between 128-191
first bit of binary IP address is 0
* first two bits of binary IP address are 10
first three bits of IP binary address are 110

5 Which operations are performed by IP? (Choose three.)

* routing packets to remote hosts
providing a physical addressing scheme
defining frames
* defining packets
* transferring data between the internet layer and the network access layer
transferring data between the internet layer and the application layer

6 Name the protocols that operate at the transport layer of the TCP/IP model. (Choose two.)

* TCP
IP
* UDP
FTP
NDS
IPX

7 Which of the following are TCP services? (Choose three.)

address resolution
* end-to-end communication
* flow control
* reliability of data delivery
path determination
data representation

8 Which OSI layers relate to the network access layer of the TCP/IP model? (Choose two.)

transport
* physical
session
network
* data link
application

9 Which model would a networking professional use to better understand the data communication process?

* OSI model
IEEE model
ANSI model
Internetworking model

10 Which TCP/IP model layer supports both LAN and WAN technologies?

* network access layer
internet layer
transport layer
application layer

11 Which layer is considered to be the host-to-network layer of the TCP/IP model?

application
presentation
transport
* network access
data link
internet

12 Which of the following would be a function of ICMP?

* It provides control and messaging capabilities.
It provides address resolution services.
It supports e-mail functionality.
It enables file transfer between hosts.
It allows remote login to distant hosts.

13 Which TCP/IP layer provides services that support a logical connection between the sending and receiving hosts?

application
network
IP
* transport
presentation
session

14 In the network shown in the accompanying graphic, where would it be appropriate to use private addressing ?

only area a
only area b
only area c
areas a and b
* areas a and c
areas a and b and c

15 In what ways are the TCP/IP and OSI models the same? (Choose three.)

* Both have an application layer.
Both have a physical layer.
Both assume circuit-switched networks.
Both have network access and data-link layers.
* Both have similar transport and network layers.
* Both assume packet-switched networks.

16 What organization developed the TCP/IP reference model?

Internet Engineering Task Force (IETF)
National Intstitute of Standards and Technology (NIST)
Department of the Navy (DoN)
* Department of Defense (DoD)
Massachusetts Institute of Technology (MIT)
Stanford University

17 How would you explain to a client that IP is unreliable?

It offers a best chance attempt of routing data, but usually delivers data to remote hosts without a problem.
* It performs no error checking and correction services, relying on the upper layers for those services.
It simply broadcasts the data out on all available paths, thus ensuring delivery.
When applied in self-healing networks, it is mostly reliable.
It uses a best guess algorithm to route and deliver data, resulting in a robust network.

18 Which of the following are included in the TCP/IP application layer? (Choose three.)

UDP
* SNMP
Netware / IPX
* TFTP
* FTP
NOS

19 How many usable hosts are available given a Class C IP address with the default subnet mask?

* 254
255
256
510
511
512

20 Which subnet mask would be assigned to the network address of 192.168.32.0 to provide 254 useable host addresses per subnetwork?

255.255.0.0
* 255.255.255.0
255.255.254.0
255.255.248.0

21 What is the network broadcast address for a Class C address of 192.168.32.0 with the default subnet mask?

192.168.0.0
192.168.0.255
192.168.32.0
192.168.32.254
* 192.168.32.255

22 What subnet mask would a network administrator assign to a network address of 128.128.32.0 to create at least 1000 host addresses per network?

255.255.0.0
255.255.248.0
* 255.255.252.0
255.255.254.0
255.255.255.0
