What is a significant disadvantage of unidirectional traffic in a ring topology?
Understand the Problem
The question is asking for a significant disadvantage of unidirectional traffic when using a ring topology. It presents multiple choice options, and we need to identify which one correctly represents the disadvantage.
Answer
Failure of a single node can disrupt the entire network.
The significant disadvantage of unidirectional traffic in a ring topology is that if one node fails to relay data, the entire network suffers.
Answer for screen readers
The significant disadvantage of unidirectional traffic in a ring topology is that if one node fails to relay data, the entire network suffers.
More Information
In a unidirectional ring topology, data has only one path to travel. This means that if one node goes down, data cannot be relayed to its destination, leading to the failure of the network communication.
Tips
A common mistake is assuming that ring topology is fault-tolerant because it forms a loop; however, the unidirectional nature limits fault tolerance.
