What is an availability challenge that vSphere can address?

The correct answer is A. Virtual machines can be proactively migrated when a server failure is imminent. Option A describes vSphere Proactive HA, which integrates with hardware health monitoring to detect degraded or failing components (such as a failing power supply or memory DIMM) and proactively evacuates virtual machines off that host before a full failure occurs.

Explanation

Option A describes vSphere Proactive HA, which integrates with hardware health monitoring to detect degraded or failing components (such as a failing power supply or memory DIMM) and proactively evacuates virtual machines off that host before a full failure occurs. This directly addresses the availability challenge of unplanned downtime. The other options are incorrect framings: B (hardware maintenance without impact) describes vMotion-enabled maintenance mode, which is an agility benefit, not an availability challenge response. C (deploying more servers) is a generic infrastructure decision, not a vSphere-specific availability feature. D (simplified DR) is a broader benefit category, not a specific availability challenge that vSphere uniquely solves.
