Which two characteristics describe vSphere HA? (Choose two.)

vSphere High Availability (HA) is designed to provide a failover mechanism for virtual machines (VMs) in a VMware environment, particularly in the event of host failures. One of its primary characteristics is the ability to restart VMs on unaffected hosts if a failure occurs. This resilience mechanism ensures that if one host goes down, the VMs running on it can be automatically restarted on other operational hosts within the cluster, maintaining uptime and availability of services.

Another important characteristic of vSphere HA is its sensitivity to datastore accessibility failures. Should a datastore become inaccessible, vSphere HA is capable of effectively restarting VMs that are still attached to unaffected datastores on other hosts in the cluster. This ability to manage VM restarts in reaction to datastore issues demonstrates the robustness of vSphere HA in maintaining operational continuity.

The other options suggest functionalities that are not inherent to vSphere HA. For instance, keeping a secondary VM running at all times is related more to VM replication or mirroring solutions rather than HA. Load balancing across hosts is more aligned with Distributed Resource Scheduler (DRS), while archiving inactive VMs pertains to maintenance strategies rather than the core focus of HA. Thus, the accurate representation of vSphere HA is its capability to restart VMs
