Therefore, "topology" is the appropriate term to fill in the blank.Rate this question:
- 9.
All of the network devices connect directly to each other in a linear fashion.
Explanation
The correct answer is Bus because in a bus network topology, all network devices are connected to a common communication medium, forming a linear structure. This means that each device is connected directly to the medium, allowing for easy communication between devices.Rate this question:
- 10.
Al of the network devices are directly connected to one central point, with no other connections between them
Explanation
The correct answer is "Star" because in a star network topology, all network devices are directly connected to a central point called a hub or switch. There are no direct connections between the devices themselves. This central point acts as a central communication hub, allowing devices to communicate with each other through the hub. This type of network topology is commonly used in home networks and small business networks due to its simplicity and ease of setup.Rate this question:
- 11.
All of the devices on a network are connected in the form of a circle
Explanation
In a ring network, all devices are connected in a circular manner, forming a closed loop. Each device is connected to its adjacent devices, creating a continuous pathway for data transmission. This type of network topology allows for efficient and reliable communication as data can flow in both directions. It also provides redundancy, as if one device fails, the data can still travel in the opposite direction. Therefore, the correct answer for this question is "Ring."Rate this question:
- 12.

When the switch determines that the destination MAC address of the frame resides on the same network segment as the source, it does not forward the frame, this is called?
Explanation
When the switch determines that the destination MAC address of the frame resides on the same network segment as the source, it does not forward the frame. This is known as "filtering." Switches use this technique to optimize network performance by only sending frames to the appropriate network segment, reducing unnecessary traffic and improving overall efficiency.Rate this question:
- 19.
Encapulates the network layer packet in a frame
Explanation
The data link layer is responsible for encapsulating the network layer packet in a frame. This layer takes the packets received from the network layer and adds necessary headers and trailers to create a frame. The frame includes information such as source and destination MAC addresses. This process allows for the transmission of data over the physical network.Rate this question:
- 20.
When the switch does not have an entry for the destination address, it transmits the frame out of all ports except for the port on which it received the frame.
Explanation
When a switch does not have an entry for the destination address, it means that the switch does not know which port to forward the frame to. In this case, the switch will use a technique called flooding. Flooding involves transmitting the frame out of all ports except for the port on which it received the frame. This ensures that the frame reaches its destination, even though the switch does not have specific information about the destination port. Flooding is a common method used in Ethernet networks to handle unknown or multicast destinations.Rate this question:
- 21.
The network sends and receives data frames one at a time, but not simultaneously
-
Half Duplex
-
Full Duplex
Correct Answer
A. Half DuplexExplanation
The network operates in half duplex mode, meaning that it can either send or receive data frames at a time, but not both simultaneously. In this mode, the network device must wait for the transmission to complete before it can receive data. This is in contrast to full duplex mode, where the network can send and receive data simultaneously, allowing for faster and more efficient communication.Rate this question:

Each device has a connection to all other devices
Correct Answer
MeshExplanation
In a mesh network, each device is directly connected to every other device in the network. This means that there are multiple paths for data to travel between devices, providing redundancy and ensuring that the network remains connected even if one or more devices fail. This type of network topology is commonly used in large-scale networks where reliability and fault tolerance are important.Rate this question:
- 25.
At least one device maintains multiple connections to other devices
Correct Answer
Partial MeshExplanation
A partial mesh network is a type of network where at least one device maintains multiple connections to other devices. In this network topology, not all devices are directly connected to each other, but there are some devices that have multiple connections. This allows for redundancy and improved fault tolerance in the network, as there are alternative paths for data transmission if one connection fails. The partial mesh topology strikes a balance between the fully connected mesh network and the less connected star or bus networks.Rate this question:
