What method can be used to eliminate single points of failure in a system?

• A. Hardware Redundancy
• B. Network Isolation
• C. Software Optimization
• D. Database Partitioning

Answer: (A)

Using hardware redundancy is an effective method for eliminating single points of failure in a system. Hardware redundancy involves having multiple components of the same type, such as servers, power supplies, or network devices, so that if one component fails, another can take its place without impacting the overall system performance. This setup ensures high availability and reliability of the system, as it minimizes the risk of a complete system failure due to a single hardware malfunction. In contrast, while network isolation can enhance security by segmenting networks, it does not specifically address single points of failure. Software optimization focuses on improving application performance but does not inherently provide redundancy. Database partitioning can help with performance and scalability, but it also does not directly prevent failures of individual components. Therefore, hardware redundancy stands out as the most direct method for addressing the issue of single points of failure.
