How does the DR vault monitor the status of the Primary Vault?

The correct approach for how the Disaster Recovery (DR) vault monitors the status of the Primary Vault involves using ICMP (Internet Control Message Protocol) ping requests. This is a fundamental networking tool that allows the DR vault to check the availability and responsiveness of the Primary Vault. By sending these ping requests, the DR vault can determine if the Primary Vault is operational and able to communicate effectively over the network.

ICMP ping requests provide a straightforward method to assess connectivity and latency without delving into the more complex aspects of data transfer or system performance metrics. This technique allows for quick status updates and helps ensure that the DR vault can react promptly in case the Primary Vault becomes unreachable, thus supporting a critical aspect of business continuity and disaster recovery planning.
