Exam 3V0-21.21 topic 1 question 90 discussion

Actual exam question from VMware's 3V0-21.21
Question #: 90
Topic #: 1
[All 3V0-21.21 Questions]

An architect is considering placement of virtual machines within an existing VMware software-defined data center (SDDC).
During the discovery phase, the following information is documented:

Cluster One -

Six ESXi hosts -

✑ vSphere HA with host failures cluster tolerates = 1
✑ Proactive HA is enabled and set to automated
✑ Fully Automated vSphere DRS
✑ Transparent Page Sharing (TPS) is enabled

Cluster Two -
✑ Eight ESXi hosts
✑ vSphere HA with host failures cluster tolerates = 1
✑ Proactive HA is disabled
✑ Partially Automated vSphere DRS
✑ Transparent Page Sharing (TPS) is disabled

Cluster Three -
✑ Three ESXi hosts
✑ vSphere HA with admission control is disabled
✑ Proactive HA is not supported
✑ Transparent Page Sharing (TPS) is disabled
Virtual Machine Resource Profile 1
✑ Memory sharing techniques should not be used
✑ Virtual machines should be automatically restarted in the event of host failure if resources are available
✑ Automated initial virtual machine placement
Virtual Machine Resource Profile 2
✑ Memory sharing techniques should not be used
✑ Virtual machines should be protected from any host hardware failures
✑ Automated initial virtual machine placement
Which two recommendations should the architect make for placement of the virtual machines to meet resource profile requirements? (Choose two.)

  • A. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster One.
  • B. All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster One.
  • C. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Two.
  • D. All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster Two.
  • E. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Three.

A and D A >> VM Profile2 >> Cluster1. Memory sharing technic (TPS) enabled, HA and Fully Automated DRS (should be protected from any host hardware failures and automate VM placement) D >> VM Profile1 >>> Cluster2. Memory sharing technic (TPS) disabled, HA and DRS Partially (initial virtual machine placement) enabled https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.resmgmt.doc/GUID-FEAC3A43-C57E-49A2-8303-B06DBC9054C5.html

Cannot be A because TPS is forbidden for both VM Profiles 1 & 2.

A should be excluded first, A: TPS enabled, but both profiles have "Memory sharing techniques should not be used" Why still select A ? this one same as Q4, but different from Q80

C. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Two. D. All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster Two. Cluster three does not say anything about DRS, and the default value for this configuration is disabled. Profile 1 and Profile 2, require that TPS should be not used and Automated initial virtual machine placement. Only cluster two accomplish these requirements.

Correct is D and E. Becouse we dont use memory sharind - that mean TPS is disabled. So Cluster one is unusable and we can use onlz cluster two and three.

I am confused by this question. Virtual Machine Resource Profile 1 and Profile 2 clearly mentioned "Memory sharing techniques should not be used". Therefore, I agree with D wher profile 1 placed on cluster 2. But I don't understand option A why profile 2 should be placed on cluster 1 since it has TPS sharing enabled. Isn't the TPS a mem sharing technique? https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.resmgmt.doc/GUID-FEAC3A43-C57E-49A2-8303-B06DBC9054C5.html

Absolutely. I seem to be alone here choosing C & D, both profiles to cluster 2. Both profiles clearly say "Memory sharing techniques should NOT be used" - which rules out cluster one for both profiles.

I believe Profile 2 on question #4 has "Virtual machines should be automatically restarted in the event of host failure regardless of available resources". With HA Admission control disabled on Cluster 3, it would power on the machine regardless of resources. This question doesn't say "regardless of available resources".
