Network+ Ring Physical Topology

1. In how many directions is data transmitted on a ring network?

One

Two

It depends on the number of nodes on the network.

It depends on the location of the nodes on the network.

Data is transmitted in only one direction on a ring network. In a ring network, each node is connected to its adjacent nodes forming a closed loop. Data travels from one node to the next in a sequential manner, following the direction of the ring. This ensures that data flows in a single direction, allowing for efficient and orderly transmission throughout the network.

Data is transmitted in only one direction on a ring network. In a ring network, each node is connected to its adjacent nodes forming a closed loop. Data travels from one node to the next in a sequential manner, following the direction of the ring. This ensures that data flows in a single direction, allowing for efficient and orderly transmission throughout the network.

2. At any given time, how many tokens circulate on a simple ring network?

One

Five

Ten

There are no limits on the number of tokens that may circulate.

In a simple ring network, only one token circulates at any given time. This means that there is only a single token moving around the network, passing through each node in a sequential manner. The presence of multiple tokens would create confusion and potential conflicts in the network's operation. Therefore, the correct answer is one.

3. What would happen to the entire network if one of the nodes in a simple ring network failed?

Performance over the entire network would suffer slightly.

The failed node would be affected, but other nodes would be fine.

Data would no longer be transmitted to or from any nodes.

Errors would be broadcast to every node.

If one of the nodes in a simple ring network failed, data would no longer be transmitted to or from any nodes. This means that the failed node would no longer be able to send or receive data, and the other nodes in the network would also be unable to communicate with each other. This would result in a complete disruption of data transmission within the entire network.

4. What ring element must a node posses before it is able to transmit over a ring network?

Sender code

Transcender

Token

A node on a ring network can transmit at any time without restriction.

In a ring network, a token is a special control message that circulates around the network. In order for a node to transmit data, it must possess the token. When a node receives the token, it gains the permission to transmit data over the network. This ensures that only one node can transmit at a time, preventing collisions and ensuring orderly communication. Therefore, the correct answer is "token."

5. What is the function of a token on a token-passing ring network?

It signals to the rest of the network to listen for traffic.

It signals to the rest of the network that the MAU is receiving an excessive number of errors.

It enables multiple nodes on the network to transmit data simultaneously.

It enables one node on the network to transmit data at any one time.

A token on a token-passing ring network is used to control access to the network. It enables one node on the network to transmit data at any one time. The token circulates around the network, and only the node in possession of the token is allowed to transmit data. This ensures that there is no collision or interference between multiple nodes trying to transmit simultaneously, thus improving the efficiency and reliability of the network.

6. A modern day Token Ring network actually uses which of the following hybrid topologies?

Star-bus

Ring-bus

Ring-tree

Star-ring

A modern day Token Ring network actually uses a hybrid topology called star-ring. In this topology, each device is connected to a central hub or switch in a star configuration, and then the hubs or switches are connected in a ring configuration. This allows for easy expansion and flexibility, as devices can be added or removed from the network without disrupting the entire system. Additionally, the ring configuration ensures that data travels in a specific direction, preventing collisions and improving network efficiency.

7. In which two of the following topologies will the addition of more nodes detrimentally affect the network's performance?

Bus

Star

Ring

Mesh

In a bus topology, all nodes are connected to a single cable, and in a ring topology, each node is connected to two neighboring nodes, forming a closed loop. In both these topologies, the addition of more nodes can lead to increased collisions and congestion, resulting in a decrease in network performance. In a bus topology, when more nodes are added, the available bandwidth gets divided among them, leading to slower communication. Similarly, in a ring topology, each node has to pass the data through all the other nodes, causing delays and reducing efficiency as more nodes are added.
