Study These Flashcards
A

encapsulation

16
Q

True or false? The right-most part of an IP address is used to identify the network that a device belongs to.

16
Q

True or false? Frames exchanged between devices in different IP networks must be forwarded to a default gateway.

17
What is the order of the two addresses in the data link frame?
destination MAC, source MAC
17
What is used to determine the network portion of an IPv4 address?
subnet mask
17
Which of the following statements are true regarding network layer and data link layer addresses? (Choose three.)
- Network layer addresses are logical and data link addresses are expressed as 12 hexadecimal digits. - Data link layer addresses are physical and network layer addresses are logical. - Network layer addresses are either 32 or 128 bits in length.
18
True or False? Data Link addresses are physical so they never change in the data link frame from source to destination.
False
18
What process is used to receive transmitted data and convert it into a readable message?
decoding
19
What is done to an IP packet before it is transmitted over the physical medium?
It is encapsulated in a Layer 2 frame.
20
What process is used to place one message inside another message for transfer from the source to the destination?
encapsulation
20
A web client is sending a request for a webpage to a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to prepare the request for transmission?
HTTP, TCP, IP, Ethernet
21
What are two benefits of using a layered network model? (Choose two.)
- It assists in protocol design. - It prevents technology in one layer from affecting other layers.
22
What is the purpose of protocols in data communications?
providing the rules required for a specific type of communication to occur
23
What is the general term that is used to describe a piece of data at any layer of a networking model?
protocol data unit
23
Which logical address is used for delivery of data to a remote network?
destination IP address
24
Which layer of the OSI model defines services to segment and reassemble data for individual communications between end devices?
transport

Which type of communication will send a message to a group of host destinations simultaneously?
multicast
27
Which three acronyms/initialisms represent standards organizations? (Choose three.)
- IANA - IEEE - IETF
28
What type of communication will send a message to all devices on a local area network?
broadcast
29
In computer communication, what is the purpose of message encoding?
to convert information to the appropriate form for transmission
29
What three requirements are defined by the protocols used in network communcations to allow message transmission across a network? (Choose three.)
- message encoding - message size - delivery options
30
What layer of the TCP/IP protocol model determines the best path through the network?
internet

broadcast
32
What type of delivery uses data link layer addresses?
local delivery
