Question
Which of the following is an essential consideration when evaluating fault tolerance in distributed algorithms?a.Recovery time and impactb.Number of nodes or participantsc.Consistency of the systemd.Throughput scalability
Solution
When evaluating fault tolerance in distributed algorithms, all of the options mentioned are essential considerations. Here's why:
a. Recovery time and impact: This is crucial because it determines how quickly the system can recover from a fault and how much the fault impacts the system's overall performance.
b. Number of nodes or participants: The more nodes or participants in a system, the higher the chances of a fault occurring. Therefore, a good fault-tolerant system should be able to handle a large number of nodes or participants.
c. Consistency of the system: In a distributed system, maintaining consistency is a challenge. If a fault occurs, it could lead to inconsistencies in the system. Therefore, a fault-tolerant system should ensure consistency even in the event of faults.
d. Throughput scalability: As the system scales and handles more transactions or operations, the likelihood of faults may increase. Therefore, a fault-tolerant system should be able to maintain its throughput as it scales.
So, all of these are essential considerations when evaluating fault tolerance in distributed algorithms.
