Exam 2V0-21.19 topic 1 question 19 discussion

B & C . Vpshere HA provide alternative host in cluster . Vsphere Vcenter HA provide passive host should active host failed

i believe this is B and E as the questions says which SHOULD be used to protect, so that means you need 2 options that work together so VCHA then DRS to seperate the VM's. If the question said COULD be used then that would mean you may select 2 seperate solutions to protect such as VCHA and FT. Correct Answer B and E

i am confused which is the correct answer..

According to the link which as been shared before... https://kb.vmware.com/s/article/1024051 Out of the given options, there are three possible answers (BCD) even though the question only asks for two.

BC is ok • What is vCenter High Availability? vCenter High Availability (vCenter HA) protects vCenter Server Appliance against host and hardware failures. The active-passive architecture of the solution can also help you reduce downtime significantly when you patch vCenter Server Appliance. • VMware vSphere High Availability • High Availability allows you to: ... Restart virtual machines on other vSphere hosts in the cluster without manual intervention when a server outage is detected. Reduce application downtime by automatically restarting virtual machines upon detection of an operating system failure. BC is ok

vSphere High Availability (HA) vSphere Symmetric Multiprocessor Fault Tolerance (vSphere FT) https://kb.vmware.com/s/article/1024051

B&C is deffo the right answer. Several other people already shared the right links, like this one https://kb.vmware.com/s/article/2148003. I am a VMware employee and I've discussed this internally. The reasoning of FT being available only for small environments and the recommendation to not use FT with VCHA (see link) makes the answer here quite straight forward.

As per vCenter HA requirement: 1. A minimum of three ESXi hosts is strongly recommended. Each vCenter HA node can then run on a different host for better protection. 2. Using VMware DRS to protect the set of hosts is recommended. In that case, a minimum of three ESXi hosts is required. So the answer may be B and E

Seems this KB confirms B and C to be correct. Key word being failover. https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.avail.doc/GUID-226A925F-BF20-4A58-BF15-4A76B4CEDC84.html

I think BCD are correct since you can use all three - vCenter HA - vSphere HA - FT https://kb.vmware.com/s/article/1024051

B&D for sure. DRS not mentioned even. https://kb.vmware.com/s/article/1024051

So FT is definitelly not supported: https://kb.vmware.com/s/article/2148003 "Are snapshots, cloning, and Fault Tolerance supported on VCHA nodes? No. It is currently not supported to use these operations on any of the VCHA nodes."

BC FT only support tiny & small VCSA ( max 4vCPU)

B & D are correct. https://kb.vmware.com/s/article/1024051 VMware vSphere Fault Tolerance (FT) can be utilized to provide continuous availability for vCenter Server by having identical vCenter Server virtual machines running on separate hosts.

B &D are correct. https://kb.vmware.com/s/article/1024051 VMware vSphere Fault Tolerance (FT) can be utilized to provide continuous availability for vCenter Server by having identical vCenter Server virtual machines running on separate hosts.

B & D B because it will give you the vCenter HA which means you will have 2 vCenter nodes in redundancy. D because FT gives you a real time switch over if something goes wrong with VM. C can't be because vSphere HA will reboot the vCenter Appliance and power on to another Host incase HA triggers which will give us downtime

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