What is the role of shared networked storage in host auto-failover?

• A. It stores the backup data only
• B. It hosts the primary database interface
• C. It provides access to all database volumes for standby hosts
• D. It is used for monitoring system health

Answer: (C)

The role of shared networked storage in host auto-failover is to provide access to all database volumes for standby hosts. In a high-availability setup, multiple hosts may be configured to work together, where one host acts as the primary and others as standby. Should the primary host fail, the standby hosts need immediate access to the same data to take over without data loss or interruption. Shared networked storage allows the standby hosts to access the database volumes that store essential data, logs, and configurations. This seamless sharing ensures that when a failover event occurs, the standby host can quickly mount the necessary volumes and become operational with minimal downtime. The architecture is designed to enhance the overall reliability and availability of the database services. Understanding this function highlights the importance of shared networked storage in maintaining business continuity, as it directly supports the failover mechanism that ensures system resilience.
