How does the functionality of AOS enhance data availability?

By parallel processing on multiple nodes
Through replication of data across different storage devices
Using a single point of failure system

The correct answer is: Through replication of data across different storage devices

The functionality of AOS (Acropolis Operating System) enhances data availability primarily through the replication of data across different storage devices. This process ensures that multiple copies of data are stored in various locations within the cluster, providing resilience against hardware failures. If one storage device experiences an issue, the data remains accessible from another location that has a replica. This approach not only increases the reliability of data storage but also facilitates disaster recovery and data integrity, as the system can quickly recover and continue to serve data without significant downtime. By having multiple replicas, AOS effectively mitigates risks associated with data loss and ensures that even in the event of hardware malfunctions, users can still access their data efficiently. This design promotes a highly available environment, which is essential for business operations that require constant access to data without interruption.
