Final answer:

vSphere High Availability (HA) cannot protect against guest OS crashes. It can handle host hardware failures and network partitions but not complete power failures or internal OS issues.

Step-by-step explanation:

vSphere High Availability (HA) is a high availability solution that provides easy-to-use, automated recovery for applications in the event of a hardware or OS outage. While vSphere HA can protect against several types of failures, it is not designed to handle Guest OS crashes. When a physical host fails, HA can restart the virtual machines on other hosts in the cluster (Host hardware failure). In case of a network partition, HA can also ensure VMs continue running by isolating and then restarting them on available hosts. During a complete power failure, vSphere HA will not function as all hosts would be down, but it is typically paired with uninterruptible power supplies (UPS) and backup generators to handle such scenarios.
