Exam 2V0-21.19D topic 1 question 19 discussion

"Which two features should an administrator use to protect a VMware vCenter Server Appliance from host and hardware failures? " "should" and "VMware vCenter Server Appliance", it means the VM is sensitive VM, zero-downtime required B&C is a zero downtime solution.

B & C VCHA already provide same capability with FT without the CPU limit. It doesn't require downtime/restart and swap immediately when the active node fail.

Answer is B & C. Check this link https://kb.vmware.com/s/article/1024051

Its asking which vSphere platform features can be leveraged as part of HA. vCenter was just an example but would apply to all critical systems in the environment which you would choose to protect regardless of compute supportability. Answer would be C and D, https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.avail.doc/GUID-63F459B7-8884-4818-8872-C9753B2E0215.html

could be B C and D. But Fault Tolerance is only supported up to 4 vCPUs and the other two features are available for every vCSA size and configuration. since this question is about the vCSA (and not a regular VM) I would take B and C. https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.avail.doc/GUID-CB46CEC4-87CD-4704-A9AC-058281CFD8F8.html https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.avail.doc/GUID-CB46CEC4-87CD-4704-A9AC-058281CFD8F8.html https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.avail.doc/GUID-226A925F-BF20-4A58-BF15-4A76B4CEDC84.html

B and C from vCenter 6.5 FT has a CPU limitation and for vcenter is pointless

B and D are correct - https://kb.vmware.com/s/article/1024051 SMP-FT was introduced in 6.0. Because FT supports up to 4cpu, small and tiny vCenter appliances can be protected with FT

B and C
