Elections officials propose keeping a two-vCPU ballot-reporting virtual machine continuously mirrored so a host failure does not interrupt the guest. Which vSphere feature provides that live secondary?
Select an answer to reveal the explanation.
Short Explanation
Fault Tolerance is a shadow copy of the ballot VM running in lockstep so a host loss does not drop the session. HA would reboot the guest after the crash. DFW only decides who may talk to whom.
Full Explanation
vSphere Fault Tolerance keeps a live secondary virtual machine synchronized with the primary so host failure does not interrupt execution, within supported vCPU limits. That is a vSphere availability feature, not micro-segmentation. vSphere HA restarts a VM after failure and accepts an outage window. NSX Edge ECMP is a north-south routing design and does not create a lockstep secondary guest.
