Networking 3
HTTP, TCP, IP, Ethernet
15. 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?
IP at the internet layer
A device receives a data link frame with data and processes and removes the Ethernet information. What information would be the next to be processed by the receiving device?
Routing
BGP and OSPF are examples of which type of protocol?
to convert information
In computer communication, what is the purpose of message encoding?
TCP
This protocol is responsible for guaranteeing the reliable delivery of information.
IETF
This standards organization is concerned with the Request for Comments (RFC) documents that specify new protocols and update existing ones.
IANA
This standards organization is responsible for IP address allocation and domain name management.
False
True or False? Data Link addresses are physical so they never change in the data link frame from source to destination.
True
True or false. Standards organizations are usually vendor-neutral.
True
True or false? Frames exchanged between devices in different IP networks must be forwarded to a default gateway.
False
True or false? The right-most part of an IP address is used to identify the network that a device belongs to.
It is encapsulated
What is done to an IP packet before it is transmitted over the physical medium?
Segment
What is the PDU associated with the transport layer?
Providing the rules
What is the purpose of protocols in data communications?
To uniquely label
What is the purpose of the sequencing function in network communication?
Subnet mask
What is used to determine the network portion of an IPv4 address?
encapsulation
What process is used to place one message inside another message for transfer from the source to the destination?
decoding
What process is used to receive transmitted data and convert it into a readable message?
broadcast
What type of communication will send a message to all devices on a local area network?
Multicast
Which delivery method is used to transmit information to one or more end devices, but not all devices on the network?
transport
Which layer of the OSI model defines services to segment and reassemble data for individual communications between end devices?
destination IP address
Which logical address is used for delivery of data to a remote network?
broadcast
Which message delivery option is used when all devices need to receive the same message simultaneously?
ICMPv4 and ICMPv6
Which of the following are protocols that provide feedback from the destination host to the source host regarding errors in packet delivery? (Choose two.)
Ethernet
Which protocol operates at the network access layer of the TCP/IP model?
Data link
Which protocol stack layer encapsulates data into frames?
RIM
Which services are provided by the internet layer of the TCP/IP protocol suite? (Choose three.)
DNS and DHCP
Which two protocols are service discovery protocols? (Choose two.)
ICMP and IP
Which two protocols function at the internet layer? (Choose two.)
multicast
Which type of communication will send a message to a group of host destinations simultaneously?
Formatting
Which step of the communication process is concerned with properly identifying the address of the sender and receiver?
FAR
Which three are components of message timing? (Choose three.)
protocol data unit
What is the general term that is used to describe a piece of data at any layer of a networking model?
Encapsulation
What is the name of the process of adding protocol information to data as it moves down the protocol stack?
destination MAC and source MAC
What is the order of the two addresses in the data link frame?
Transport
UDP and TCP belong to which layer of the TCP/IP protocol?
Encoding
What is the process of converting information into the proper form for transmission?
Segmentation
What is the process of dividing a large data stream into smaller pieces prior to transmission?
Electric wiring and connectors
What types of standards are developed by the Electronics Industries Alliance (EIA)?
IANA, IEEE, IETF
Which three acronyms/initialisms represent standards organizations?
