Multiple Choice:
In the OSI 7-Layer Model, what does “OSI” stand for?
Correct Answer
A. Open Systems Interconnection
Explanation
The correct answer is "Open Systems Interconnection." The OSI 7-Layer Model is a conceptual framework that standardizes the functions of a communication system into seven different layers. These layers help in understanding and designing network protocols and interactions. The term "Open Systems Interconnection" refers to the model's goal of providing a standardized framework for communication between different computer systems, regardless of their underlying hardware or software.
3.
True/False
Each Layer of the OSI 7-Layer Model interacts with any of the other layer.
Correct Answer
B. False
Explanation
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.
4.
Multiple Choice:
Which Layer deal with assigning Port numbers to data?
Correct Answer
A. Layer 4 – Transport
Explanation
Layer 4, which is the Transport layer, is responsible for assigning port numbers to data. This layer ensures that the data is correctly delivered from the source to the destination by establishing a reliable connection, managing flow control, and handling error recovery. Port numbers are used to identify specific applications or services running on devices, allowing the Transport layer to correctly deliver the data to the intended recipient.

Multiple Choice:
What does an IP Address represent?
Correct Answer
A. A device’s virtual location on a network
Explanation
An IP address represents a device's virtual location on a network. It is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. The IP address allows devices to communicate and send data to each other within the network. It does not represent a device's physical location or serve as a permanent and unique identification number.
6.
Multiple Choice:
Which of the following might represent an IP address?
Correct Answer
A. 112.59.212.148
Explanation
The correct answer is 112.59.212.148. This is because an IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It consists of four sets of numbers separated by periods, with each set ranging from 0 to 255. The given answer, 112.59.212.148, follows this format and is a valid representation of an IP address.
7.
Multiple Choice:
What is a Router’s primary purpose?
Correct Answer
A. To transport data between networks
Explanation
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.
8.
True/False
An IP Address specifies what device will be found at a network location.
Correct Answer
B. False
Explanation
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.
9.
Multiple Choice:
What type of device creates a list of MAC Addresses to be shares across a network?
Correct Answer
A. A Switch
Explanation
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.
10.
Multiple Choice:
Which of the following statements about communication protocols is true?
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.
11.
Multiple Choice:
Which of the following networks is acceptable to run Q-Sys?
Correct Answer
A. A Gigabit Network
Explanation
A Gigabit Network is acceptable to run Q-Sys because Q-Sys is a high-performance audio, video, and control system that requires a fast and reliable network connection. A Gigabit Network provides a data transfer rate of 1 gigabit per second, which is significantly faster than a 100 MB Network or a 56k Modem. This ensures that Q-Sys can efficiently handle the transmission of large amounts of audio and video data without experiencing lag or latency issues.
12.
Multiple Choice:
Approximately how long does it take a segment of data to enter and exit a switch?
Correct Answer
A. 22 microseconds
Explanation
A segment of data takes approximately 22 microseconds to enter and exit a switch. This indicates the time it takes for the data to be processed and forwarded through the switch, ensuring efficient communication between devices.

Choose all that apply:
Which of the following are requirements of your Switch? (Choose all that apply)
Correct Answer(s)
A. Wire-speed non-blocking delivery
B. 40 kb/port dedicated buffering
C. Total switch fabric > port quantity
Explanation
The requirements of a switch include wire-speed non-blocking delivery, which means that the switch should be able to forward packets at the maximum speed of the network without any congestion or blocking. Additionally, the switch should have 40 kb of dedicated buffering per port, which ensures that packets can be temporarily stored and queued during high traffic periods. Lastly, the total switch fabric, which represents the internal capacity of the switch, should be greater than the number of ports to ensure efficient data transmission.
14.
If you want to know how many remaining network channels are available in your design you need to:
Correct Answer
A. Select “Check Design” in the File Menu or Press Shift+F6
Explanation
To determine the number of remaining network channels available in the design, the correct approach is to select "Check Design" in the File Menu or press Shift+F6. This action will likely trigger a process that analyzes the design and provides information on the available network channels. The other options mentioned, such as counting inputs on the back panel of the Core or checking the properties panel, may not necessarily provide the desired information about the remaining network channels.
