Routing

BGP and OSPF are examples of which type of protocol?

Encoding

What is the process of converting information into the proper form for transmission?

Ethernet

Which protocol operates at the network access layer of the TCP/IP model?

IEEE, IANA, IETF

Which three acronyms/initialisms represent standards organizations? (Choose three.)

to convert info to the appropriate form of transmission

In computer communication, what is the purpose of message encoding?

TCP

This protocol is responsible for guaranteeing the reliable delivery of information.

data link

Which protocol stack layer encapsulates data into frames?

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?

Ethernet, TCP, IP, HTTP

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?

Internet Engineering Task Force (IETF)

This standards organization is concerned with the Request for Comments (RFC) documents that specify new protocols and update existing ones.

Internet Assigned Numbers Authority (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.

Transport

UDP and TCP belong to which layer of the TCP/IP protocol?

It assists in protocol design, it prevents technology in one layer from affecting other layers.

What are two benefits of using a layered network model? (Choose two.)

It is Encapsulated in a layer 2 frame

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?

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, Source Mac

What is the order of the two addresses in the data link frame?

Segmentation

What is the process of dividing a large data stream into smaller pieces prior to transmission?

Providing the rules required for a specific type of communication to occur

What is the purpose of protocols in data communications?

To uniquely label transmitted segments of data for proper reassembly by the reciever.

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?

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?

Electric wiring and connectors

What types of standards are developed by the Electronics Industries Alliance (EIA)?

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?

ICMPv6, ICMPv4

Which of the following are protocols that provide feedback from the destination host to the source host regarding errors in packet delivery? (Choose two.)

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.

Which of the following statements are true regarding network layer and data link layer addresses? (Choose three.)

Internet Protocol, Routing Protocols, Messaging

Which services are provided by the internet layer of the TCP/IP protocol suite? (Choose three.)

Formatting

Which step of the communication process is concerned with properly identifying the address of the sender and receiver?

Flow control, Access method, Response timeout

Which three are components of message timing? (Choose three.)

DNS, DHCP

Which two protocols are service discovery protocols? (Choose two.)

DNS, DHCP

Which two protocols belong in the TCP/IP model application layer?

IP, ICMP

Which two protocols function at the internet layer? (Choose two.)
