Which of the following protocols are examples of TCP/IP data-link layer protocols? (Choose two answers.) Ethernet, HTTP, IP,UDP,SMTP,TCP,802.11
Ethernet
802.11
Which of the following protocols are examples of TCP/IP transport layer protocols? (Choose two answers.), A Ethernet, B HTTP, C IP, D UDP, E SMTP, F TCP
UDP TCP
IP functions at what layer of the OSI Reference Model?, A Transport, B Network, C Physical, D Session
Network
In the TCP/IP model, which layer defines the interface between software running on the computer and the network itself?
A) The transport layer is incorrect because it deals with data delivery and flow control.
In IT, what term refers to a small network that is used for business purposes, typically in the home of a business or employee? A) Organizational network B) Enterprise network C) IT network D) SOHO network E) Cloud network
D) When you start to work in a new industry, it is good to be familiar with some of the most popularly used terms. When referring to a small network that is used for business purposes and is typically located in the home of the business (home office) or employee, the term SOHO (Small Office, Home Office) is typically used.
Which layer of the TCP/IP Model defines end-to-end forwarding of packets? A The Network layer, B The Application layer, C The Transport layer, D The Link layer
Network Layer
Which of the following terms represents L3PDU in the OSI model, which includes the network layer header and its encapsulated data?, A Data, B Segment, C Packet, D Frame
Packet
Where does routing occur within the DoD TCP/IP reference model? A. application B. internet C. network D. Data Link
What is B. Internet TCP/IP not OSI
Which layer of the TCP/IP model defines the rules for data packet recovery?, A Transport,B Internet,C Application,D Data link
A) Transport is correct because the transport layer protocols deal with error recovery of data. The transport layer also handles the mechanism to guarantee delivery across the network. The other layers do not.
At which of the OSI model layers are rules defined that determine how a device can send data over a particular medium? A) Presentation B) Application C) Transport D) Network E) Data link
E) Of the seven OSI network model layers, the data link layer determines how a device can send data over a particular medium, such as Ethernet data link protocols.
The process of TCP on one computer marking a TCP segment as segment 1, and the receiving computer then acknowledging the receipt of TCP segment 1 is an example of what? A Data encapsulation, B Same-layer interaction, C Adjacent-layer interaction, D OSI model, E All of these answers are correct.
Same Layer Interaction
The process of HTTP asking TCP to send some data and making sure that it is received correctly is an example of what? A, Same-layer interaction, B Adjacent-layer interaction, C OSI model, D All of these answers are correct.
Adjacent-layer interaction
What are the two main services provided by the network layer of the TCP/IP model? A) Compression B) Addressing C) Routing D) Reliability E) Encryption
B) Addressing and routing are correct answers because addressing deals with placing the correct IP address in the packet, and routing deals with getting the packet to the correct destination.
Which protocol is an example of a TCP/IP application layer protocol?A) HTTP B) UDP C) IP E) Ethernet
A) HTTP is an example of a protocol that operates at the application layer of the TCP/IP model.
The process of a web server adding a TCP header to the contents of a web page, followed by adding an IP header and then adding a data-link header and trailer, is an example of what? A Data encapsulation B Same-layer interaction,C OSI model, D All of these answers are correct.
Data encapsulation
Which OSI encapsulation term can be used instead of the term frame?, A Layer 1 PDU, B Layer 2 PDU, C Layer 3 PDU, D Layer 5 PDU, E Layer 7 PDU
Layer 2 PDU
Which layer in the OSI reference model is responsible for determining the availability of the receiving program and checking to see if enough resources exist for that communication? A. transport B. network C. presentation D. session E. application
What is Application The Application layer is responsible for identifying and establishing the availability of the intended communication partner and determining whether sufficient resources for the intended communication exist.
The process of forwarding an IP packet from host to host is known as ________. A) Delivery B) Switching C) Routing D) Sending
C) Routing is the correct answer because routing deals with getting the packet to the correct destination. Switching deals with getting frames to their correct destinations. Routing works much like the postal service to deliver messages to the correct destination.
Which layer of the OSI model defines functions related to data delivery, error recovery, and flow control? A) Application layer B) Presentation layer C) Session layer D) Transport layer E) Network layer F) Data link layer G) Physical layer
D) The transport layer focuses on issues related to data delivery to another computer (for example, error recovery and flow control).

Which of the following terms is used specifically to identify the entity created when encapsulating data inside data-link layer headers and trailers? , A Data, B Chunk, C Segment, D Frame, E Packet
Frame
The term segment refers to which layer PDU?, A Application layer PDU, B Transport layer PDU, C Internetwork layer PDU, D Network Access PDU
Transport layer PDU
An administrator pings the default gateway at 10.10.10.1 and sees the output as shown. At which OSI layer is the problem? A. data link layer B. application layer C. access layer D. session layer E. network layer
What is E. Network Layer
What name is given to the process of enclosing data with headers and trailers as the data is moved down the TCP/IP model? A) Condensing B) Inclosing C) Encryption D) Encapsulation
D) Encapsulation is the correct answer because as the data moves down the TCP/IP model and each layer attaches its control data, this process is known as encapsulation.
Which of the following layers in the OSI model corresponds to the Internet layer in the original TCP/IP model? A) Application B) Transport C) Network D) Physical
C) The Network layer in OSI is equivalent to the Internet layer in the original TCP/IP and has been updated to be the Network layer in the new TCP/IP model.
