What does the 'Failover' capability in VMware refer to?

The 'Failover' capability in VMware refers to the automatic switching to a standby system or resource when the primary system fails. This process ensures high availability and continuity of services, minimizing downtime and disruption in the event of a failure. Failover is typically implemented in environments that require reliability, enabling critical applications to remain operational by redirecting workloads to a backup system seamlessly.

The focus on automatic switching is crucial in disaster recovery scenarios, where the system must promptly and effectively respond to hardware or software failures without user intervention. This capability is vital for maintaining business operations and providing resilience against unexpected outages.

In contrast, options that imply manual intervention, such as restoring a VM or altering VM configurations, do not align with the concept of failover, which is inherently designed to function automatically. Additionally, improving network traffic doesn't directly relate to the failover process, which is more focused on system resilience and uptime rather than performance enhancement. Therefore, the option that defines failover as an automatic transition to a standby system is the one that accurately captures its essence within VMware's functionality.
