What is a benefit of using backup components in a fault-tolerant server?

• A. Increases cost of operations
• B. Reduces the chance of server failures
• C. Requires more physical space
• D. Limits server capabilities

Answer: (B)

Utilizing backup components in a fault-tolerant server significantly reduces the chance of server failures. This is achieved by incorporating redundant systems or components that can take over if the primary ones fail. For example, having multiple power supplies, hard drives, or network connections ensures that if one component encounters a failure, others can maintain the operations without interruption. This redundancy is crucial for critical systems that require high availability, as it minimizes downtime and enhances overall reliability. Therefore, the implementation of such backup systems directly contributes to the operational continuity of the server, making it a vital aspect of fault tolerance in server management.
