Exam 3V0-624 topic 1 question 33 discussion

Correct Answer: AC https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.avail.doc/GUID-83FE5A45-8260-436B-A603-B8CBD2A1A611.html

I just finished the exam and passed with 458/500 (10/01/2020) Question appeared with select three instead of select two. So correct are DRS, vMotion and vSphere HA.

Correct answer AC based on the FT requirements: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-83FE5A45-8260-436B-A603-B8CBD2A1A611.html "Cluster Requirements for Fault Tolerance You must meet the following cluster requirements before you use Fault Tolerance. Fault Tolerance logging and VMotion networking configured. See Configure Networking for Host Machines. vSphere HA cluster created and enabled. See Creating a vSphere HA Cluster. vSphere HA must be enabled before you can power on fault tolerant virtual machines or add a host to a cluster that already supports fault tolerant virtual machines."

A & E I think it's E because when you setup DRS you can activate proactive HA which imply the use of vMotion (C). Also without proactive HA, the vMotion will be utilized in fully automated mode. TL;DR if you choose E. DRS, answer C is automatically included.

I think A и С https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.avail.doc/GUID-57929CF0-DA9B-407A-BF2E-E7B72708D825.html

AE https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.avail.doc/GUID-F5264795-11DA-4242-B774-8C3450997033.html

Correct answer: AE "Virtual volume datastore" -> Not Supported with Fault Tolerance "Storage-based policy management" -> Not Supported with Fault Tolerance "Snapshots" -> Not Supported with Fault Tolerance (with specific note for VADP) "loss of connectivity to a virtual machine" is vague; a VM can lose network connectivity from different reasons and vMotion cannot help in any way: - if a physical switch is down, - if the host where the VM reside is down, - if the host lost the connection to his datastore where the VM reside DRS can be taken into consideration if "Predictive DRS" is set in combination with vRealize Operation Manager, see below an extras from VMware vSphere - Design Workshop: "Historically, vSphere DRS has been reactive. It reacts to any changes in VM workloads and migrates the VMs to distribute load across different hosts. In vSphere 6.5, with vCenter Server working together with vRealize Operations Manager, DRS can act upon predicted future changes in workloads. In addition to that, with vCenter 6.5 DRS is Network-Aware https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/drs-vsphere65-perf.pdf

When power failure, vmotion will not use know

DRS only support with EVC. without EVC DRS is disabled for an FT enabled VM https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.avail.doc/GUID-59EA59EB-C60F-4815-AE2E-7A38506C516C.html

yes AC is correct
