Answer-first summary for fast verification
Answer: Employing data replication across multiple nodes to ensure data is always available, even in the event of a node failure., Implementing single-thread processing to simplify the system architecture and reduce overhead.
**Correct Options: C. Data replication and A. Single-thread processing** **Explanation:** Data replication is a cornerstone strategy for achieving fault tolerance in distributed systems, ensuring data availability and integrity by maintaining copies across multiple nodes. Single-thread processing, while not directly related to fault tolerance, can simplify system architecture but does not inherently provide fault tolerance. The combination of these strategies is not typically recommended as single-thread processing lacks the redundancy needed for fault tolerance. **Why other options are incorrect:** - **B. Gradient boosting:** This is a machine learning technique for improving model accuracy, not a fault tolerance strategy. - **D. Model regularization:** This technique is used to prevent overfitting in machine learning models and is unrelated to fault tolerance in distributed systems. - **E. Both C and A:** While data replication is effective for fault tolerance, single-thread processing does not contribute to fault tolerance and thus this option is incorrect.
