ISC2 CISSP Practice Question

The correct answer is implementing a consensus mechanism. Distributed systems face the challenge of maintaining data consistency across multiple nodes that may be geographically dispersed. Consensus mechanisms are specifically designed to ensure that distributed systems can reach agreement on data values and state even when nodes fail or network partitions occur.

While end-to-end encryption is important for protecting data in transit, it doesn't address the fundamental consistency challenges in distributed systems. Similarly, load balancing helps with performance and availability but doesn't ensure data consistency. Network segmentation is useful for security isolation but doesn't solve the distributed consensus problem that affects data integrity across nodes.
