What is an availability challenge that vSphere can address?

Question

Options

• AVirtual machines can be proactively migrated when a server failure is imminent
• BHardware maintenance can be performed at any time without application impact
• CMore servers can be deployed to provide higher availability
• DDisaster recovery is greatly simplified

• B

• C

Explanation

vSphere addresses the availability challenge of hardware maintenance by allowing live migration of virtual machines off a host before maintenance begins. Using vMotion, an administrator can evacuate all running VMs from a physical host to other hosts in the cluster with zero downtime, perform the maintenance, then return the VMs - all without any application impact. Option A is incorrect because vSphere reacts to failures rather than predicting imminent hardware failure for proactive migration (that requires additional tools). Option C (deploying more servers) is an infrastructure decision, not a vSphere availability feature. Option D (simplified DR) is a benefit, but it is not specific to the 'availability' challenge described.
