CCNA1 - Chapter 2

since sebelum ni ramai gak yg tanya pada saya, nape saya masukkan entri CCNA Exploration ni dalam blog saya.. ekceli, saya malas nak create another blog khas utk CCNA nih.. since skarang ni saya tgh amik CCNA as a part of my studies, so saya nak share2 la.. apa soalan n jawapan yg saya dapat masa saya amik chapter test tu.. even i'm still not completing my test.. tp as long as dapat share.. i think it worth.. ;)

corruption of a frame during transmission
data reassembled at the destination
retransmitted packets due to lost communication
a layer specific encapsulation

A, C, D
B, E, G, H
C, D, G, H, I, J
D, E, F, H, I, J
E, F, H, I, J

8. What can be identified by examining the network layer header?

the destination device on the local media
the destination host address
the bits that will be transferred over the media
the source application or process creating the data

9. What is the proper order of the layers of the OSI model from the highest layer to the lowest layer?

physical, network, application, data link, presentation, session, transport
application, physical, session, transport, network, data link, presentation
application, presentation, physical, session, data link, transport, network
application, presentation, session, transport, network, data link, physical
presentation, data link, session, transport, network, physical, application

10. What is the primary purpose of Layer 4 port assignment?

to identify devices on the local media
to identify the hops between source and destination
to identify to the intermediary devices the best path through the network
to identify the source and destination end devices that are communicating
to identify the processes or services that are communicating within the end devices

11. Select the statements that are correct concerning network protocols. (Choose three.)

define the structure of layer specific PDU's
dictate how to accomplish layer functions
outline the functions necessary for communications between layers
limit the need for hardware compatibility
require layer dependent encapsulations
eliminate standardization among vendors

12. Which two layers of the OSI model have the same functions as the TCP/IP model Network Access Layer? (Choose two.)
Network
Transport
Physical
Data Link
Session

13.
Refer to the exhibit. "Cell A" at IP address 10.0.0.34 has established an IP session with "IP Phone 1" at IP address 172.16.1.103. Based upon the graphic, which device type best describes the function of wireless device "Cell A?"

the destination device
an end device
an intermediate device
a media device

14.

Refer to the exhibit. What type of network is shown?

WAN
MAN
LAN
WLAN

15. What is the purpose of the TCP/IP Network Access layer?

path determination and packet switching
data presentation
reliability, flow control, and error detection
network media control
the division of segments into packets

16. What is a primary function of the trailer information added by the data link layer encapsulation?

supports error detection
ensures ordered arrival of data
provides delivery to correct destination
identifies the devices on the local network
assists intermediary devices with processing and path selection

17. Which statements correctly identify the role of intermediary devices in the network? (Choose three.)

determine pathways for data
initiate data communications
retime and retransmit data signals
originate the flow of data
manage data flows
final termination point for data flow

18. Which three statements best describe a Local Area Network (LAN)? (Choose three.)

A LAN is usually in a single geographical area.
The network is administered by a single organization.
The connection between segments in the LAN is usually through a leased connection.
The security and access control of the network are controlled by a service provider.
A LAN provides network services and access to applications for users within a common organization.
Each end of the network is generally connected to a Telecommunication Service Provider (TSP).

19. During the encapsulation process, what occurs at the data link layer?

No address is added.
The logical address is added.
The physical address is added.
The process port number is added.

20. What device is considered an intermediary device?

file server
IP phone
laptop
printer
switch

21. What are two functions of encapsulation? (Choose two.)

tracks delay between end devices
enables consistent network paths for communication
allows modification of the original data before transmission
identifies pieces of data as part of the same communication
ensures that data pieces can be directed to the correct receiving end device
