What are the "Common Physical Components of a Network"
- A.
Switch
- B.
PC
- C.
Cable
- D.
MS Windows
- E.
Electric Power
Correct Answer(s)
A. Switch
B. PC
C. CableExplanation
The common physical components of a network include a switch, which is a device that connects multiple devices together and allows them to communicate with each other. A PC, or personal computer, is another component that is connected to the network and can send and receive data. Cables are used to physically connect the devices together and transmit the data. MS Windows, which is a computer operating system, is not a physical component of the network. Electric power is necessary for the network components to function, but it is not considered a physical component of the network itself.Rate this question:

Waht are the main Characteristics of a Network
- A.
Speed
- B.
Data flow
- C.
CSMA/CD
- D.
Security
- E.
Scalability
Correct Answer(s)
A. Speed
D. Security
E. ScalabilityExplanation
The main characteristics of a network are speed, security, and scalability. Speed refers to the rate at which data can be transmitted and received within the network. Security involves measures taken to protect the network from unauthorized access and ensure the confidentiality and integrity of data. Scalability refers to the ability of the network to accommodate increasing demands and expand its capacity without significant performance degradation. These characteristics are essential for a network to efficiently and effectively handle data flow and ensure smooth operations.Rate this question:

What is the Network Topology
- A.
Shapes and size of the network
- B.
Physical layout of the devices and cabling
- C.
Network Structural Design
- D.
Type of cabling used in the network
- E.
All of the Above
Correct Answer
B. Physical layout of the devices and cablingExplanation
The correct answer is "Physical layout of the devices and cabling." Network topology refers to the arrangement of devices and cables in a network. It describes how devices are connected and the physical layout of the network, such as whether it is a bus, star, ring, or mesh topology. The other options mentioned, such as shapes and size of the network, network structural design, and type of cabling used, are related to network topology but do not fully encompass its definition.Rate this question:

What are the 3 main type of the Topology ?
- A.
BUS
- B.
Mash
- C.
Full Mash
- D.
Star
- E.
RIng
Correct Answer(s)
A. BUS
D. Star
E. RIngExplanation
The 3 main types of topology are BUS, Star, and Ring. In a BUS topology, all devices are connected to a single cable, forming a linear network. In a Star topology, all devices are connected to a central hub or switch, creating a centralized network. In a Ring topology, devices are connected in a circular manner, where each device is connected to two other devices, forming a closed loop network.Rate this question:

What is the Bus Topology
- A.
Single Network
- B.
Multiple network with Single Cable
- C.
Linear BUS
- D.
Linear Network Topology with CSMA/CD
- E.
IEEE 802 network
Correct Answer
C. Linear BUSExplanation
The correct answer is "Linear BUS." The bus topology is a network configuration in which all devices are connected to a single cable called a bus. In this topology, data is transmitted in a linear manner from one device to another. Each device on the network receives all transmitted data, but only the intended recipient processes it. This topology is simple and cost-effective, but it can be prone to performance issues if there are too many devices or if the main cable fails.Rate this question:

What is logical bus topology
- A.
Ethernet hub.
- B.
CSMA/CD
- C.
Logical Cables
- D.
Linear Network
- E.
None Of the Above
Correct Answer
A. Ethernet hub.Explanation
The correct answer is "Ethernet hub." In a logical bus topology, all devices are connected to a central hub using a single cable. The hub acts as a central point for data transmission and allows multiple devices to communicate on the same network. This topology is commonly used in Ethernet networks, where the hub facilitates the communication between devices using the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol. It is important to note that logical bus topology refers to the way devices are connected and communicate, rather than the physical arrangement of cables.Rate this question:

What is Star and Extended-Star Topologies
- A.
Star network is expanded to include an additional network device
- B.
Extended to out side the office
- C.
Multiple Star netowork
- D.
Combination of BUS and Star topology
- E.
Each Cable is connected to a device
Correct Answer
A. Star network is expanded to include an additional network deviceExplanation
The correct answer is "star network is expanded to include an additional network device". This means that in a star topology, where all devices are connected to a central hub or switch, an extra network device is added to expand the network. This could be another hub or switch that connects to the existing central device, allowing for more devices to be connected to the network. This expansion helps to increase the capacity and reach of the network.Rate this question:

Extended-Star Topology are (choos 2 options)
- A.
A common deployment of an extended-star topology
- B.
Star hierarchical design of the network
- C.
Central connection point that is a device, such as a hub, switch, or router,
- D.
Implement than the physical bus topology
- E.
Each device is connected to the central device
Correct Answer(s)
A. A common deployment of an extended-star topology
B. Star hierarchical design of the networkExplanation
The correct answer options, "A common deployment of an extended-star topology" and "Star hierarchical design of the network," both describe characteristics of an extended-star topology. In an extended-star topology, multiple star topologies are interconnected, creating a hierarchical network design. This design allows for scalability and easier management of the network. Each star within the extended-star topology has its own central connection point, such as a hub, switch, or router, which connects to the central device of the overall network. This design is more efficient and easier to implement than a physical bus topology, where each device is connected to a single shared communication line.Rate this question:

What is the problem with the pure extended star Topology
- A.
If the central node point fails, large portions fail
- B.
If the central node point fails, some of portions still working
- C.
If the central node point fails, Nothing happened to other portions
- D.
If the central node point fails, CSMACD will block the other portions
- E.
If the central node point fails large portions still working
Correct Answer
A. If the central node point fails, large portions failExplanation
In a pure extended star topology, all nodes are connected to a central node. If the central node fails, it means that the entire network loses its connectivity. Since the central node is responsible for connecting all the other nodes, if it fails, it will result in a failure of a large portion of the network. Therefore, the correct answer is "if the central node point fails, large portions fail."Rate this question:

What most of extended-star topologies employ (Choos 1 options)
- A.
A redundant connection to a separate set of connection devcies
- B.
None redundant connection to a separate set of connection devcies
- C.
A redundant connection to a new set of connection devices
- D.
A redundant connection to a separate set of connection to connect Router
Correct Answer
A. A redundant connection to a separate set of connection devciesExplanation
Most extended-star topologies employ a redundant connection to a separate set of connection devices. This means that there is an additional connection available in case the primary connection fails, ensuring a backup and maintaining network reliability. By having a separate set of connection devices, the network can continue to function even if one set of devices experiences issues.Rate this question:
