A) physical layer
B) data link layer
C) presentation layer
D) transport layer
E) session layer

A) physical layer
B) data link layer
C) presentation layer
D) transport layer
E) session layer
F)application layer

Accepted Answer

The session layer (Layer 5) in the OSI model is responsible for establishing, managing, and terminating connections between applications. This includes setting up communication sessions, ensuring they remain open for the duration of the exchange, and closing them once the communication is complete.

Question 8

Data communication is as dependent upon the rules defined by the OSI model as it is upon the circuits used to connect the devices.

Accepted Answer

The OSI model provides a framework for understanding the rules and protocols for data communication, while the physical circuits enable the actual connection between devices. Both are essential for effective data communication.

Question 9

The purpose of data networking protocols is to:
A) define the rules, methods, and standards used by the network
B) ensure that the information traveling on the network reaches its destination
C) determine what path the information should follow, the type of vehicle it should ride in, the number of stops it needs to make, the alternate routes available, and the time allowed for the trip
D) all of the above

Accepted Answer

Data networking protocols serve multiple purposes: they establish the rules, methods, and standards for how data is transmitted across a network (A); they ensure data reaches its intended destination correctly (B); and they manage the path, transportation method, stops, alternate routes, and timing for data packets traveling across the network (C). Thus, all the options collectively describe the functions of networking protocols.

Question 10

The protocols defining the pin outs of the connector, the gauge of cable, the number of twists per foot, the distance the signal travels, the voltage levels, and the frequency range, among other things, are the:
A) network layer protocols
B) data link layer protocols
C) physical layer protocols
D) all of the above

Accepted Answer

The answer of The protocols defining the pin outs of...

Question 11

The protocols that are responsible for routing frames through the network, error checking data, and working with the higher level protocols to ensure correct transmission of data are the:
A) network layer protocols
B) data link layer protocols
C) physical layer protocols
D) all of the above

Accepted Answer

Network layer protocols are responsible for routing frames through the network and working with higher-level protocols to ensure correct data transmission.

Question 12

The data link layer that is the closest to the physical layer is the ________ layer.

Accepted Answer

The answer of The data link layer that is the...

Question 13

Numerous layer 2 transmission protocols:
A) are used to route data information from device to device
B) frame or format the information per standards
C) are usually defined as being either connection-oriented or connectionless
D) all of the above

Accepted Answer

All of the above are true about layer 2 transmission protocols. They are used to route data information from device to device, frame or format the information per standards, and are usually defined as being either connection-oriented or connectionless.

Question 14

The lower layer protocols, such as the MAC and the physical layer, do not have to build specific interfaces to the higher layer protocols, such as layer 3, in order to communicate.

Accepted Answer

Lower layer protocols like MAC (Medium Access Control) and the physical layer are designed to provide services to the higher layers (like layer 3, the network layer) through a standardized interface, without needing to build specific interfaces for each higher layer protocol. This abstraction allows for interoperability and modularity in the network architecture.

Question 15

The protocol that establishes a session end-to-end using a network address, such as a domain name like spidercom.com in an Internet connection is:
A) ATM
B) PPP
C) SDLC
D) HDLC

Accepted Answer

PPP (Point-to-Point Protocol) is used to establish a direct connection between two nodes over a serial link, such as an Internet connection, and can use network addresses like domain names for connection setup.

Question 16

Networking professionals use the 7 layer OSI stack to troubleshoot, design and plan communications networks.

Accepted Answer

The 7 layer OSI (Open Systems Interconnection) model is a conceptual framework used by networking professionals to understand, troubleshoot, design, and plan communications networks by dividing the process into seven distinct layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
