True/False Each Layer of the OSI 7-Layer Model interacts with any of the other layer.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Each layer of the OSI 7-Layer Model interacts only with the adjacent layers. This means that a layer can only communicate with the layer directly above it and the layer directly below it. The purpose of this design is to ensure that each layer performs a specific set of functions and does not have to be concerned with the operations of other layers. This allows for modularity and flexibility in the design of network protocols. Therefore, the given answer "False" is correct.Rate this question:

- A.
To transport data between networks
- B.
To define a network by the MAC Addresses of the devices it is connected to
- C.
To confirm delivery of data and request additional data packets
Correct Answer
A. To transport data between networksExplanation
A router's primary purpose is to transport data between networks. Routers are networking devices that receive data packets from one network and then determine the best path for the data to reach its destination on another network. They use routing tables and protocols to make these decisions and ensure efficient and reliable data transmission between networks.Rate this question:

True/False An IP Address specifies what device will be found at a network location.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
An IP address does not specify what device will be found at a network location. It is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves as an identifier for the device and helps in routing data packets across the network, but it does not provide information about the specific device itself.Rate this question:

Multiple Choice: What type of device creates a list of MAC Addresses to be shares across a network?
- A.
A Switch
- B.
A Router
- C.
A Core
Correct Answer
A. A SwitchExplanation
A switch is a type of device that creates a list of MAC addresses to be shared across a network. Switches operate at the data link layer of the OSI model and use MAC addresses to forward data packets to the correct destination device. By maintaining a table of MAC addresses, switches can efficiently direct traffic within a network by sending data only to the appropriate device. This allows for faster and more efficient communication within a network. In contrast, routers operate at the network layer and use IP addresses to make routing decisions between different networks. A core is a high-performance switch that serves as the backbone of a network.Rate this question:

Multiple Choice: Which of the following statements about communication protocols is true?
- A.
Q-LAN sends control data using TCP and audio using UDP.
- B.
Q-LAN sends audio using TCP because it is faster than UDP.
- C.
Q-LAN sends all its proprietary control data using QDP.
Correct Answer
A. Q-LAN sends control data using TCP and audio using UDP.Explanation
Q-LAN sends control data using TCP and audio using UDP because TCP provides reliable and ordered delivery of data, which is important for control data to ensure that it is received correctly and in the correct order. On the other hand, UDP is used for audio because it provides faster transmission with lower latency, which is crucial for real-time audio streaming where minor delays can cause disruptions in the audio playback.Rate this question:
