A company runs a stateful application on-premises with a single active node and a passive standby node. The application uses a shared storage array. The company wants to automate failover to the standby node if the active node fails. The failover must be completed within 5 minutes. Which approach should they use?

Use a manual failover runbook that an operator follows to promote the standby node.

Use a load balancer that is configured to send traffic to the standby node if the active node fails.

Use a DNS record with a short TTL and update it to point to the standby node's IP address during a failure.

Use a cluster manager that monitors the active node and automatically promotes the standby node to active, using a virtual IP (VIP) for client access.

To protect against a regional failure (e.g., a natural disaster affecting an entire region), where should an application be deployed?

Across multiple availability zones in one region

What is the primary purpose of an automated failover mechanism?

To monitor application performance

To switch to a standby resource without manual intervention

To increase the capacity of the primary resource

In an eventually consistent data store, what does 'eventual' mean?

Updates are only applied during off-peak hours

Updates will propagate to all replicas over time

Updates are never guaranteed to be applied

Updates are applied instantly to all replicas
