Exam 2V0-21.23 topic 1 question 102 discussion

Actual exam question from VMware's 2V0-21.23
Question #: 102
Topic #: 1
[All 2V0-21.23 Questions]

Refer to the exhibit.



An administrator is tasked with adding new capacity to an existing software-defined data center (SDDC).

• The SDDC currently hosts two vSphere clusters (ClusterA and ClusterB) with different CPU compatibilities.
• vSphere vMotion and vSphere Distributed Resource Scheduler (DRS) are currently in use in the SDDC.
• The new capacity will be implemented by provisioning four ESXi hosts running a new generation of Intel Skylake CPUs.
• All workload virtual machines (VMs) must support live migration to any cluster in the SDDC.

The administrator noticed the running critical "evc1" virtual machine (VM) shown in the exhibit is not migrating using vSphere vMotion to the original Clusters A or B.

Which three steps must the administrator take to support this functionality? (Choose three.)

  • A. Disable the Enhanced vMotion Compatibility (EVC) on the VM.
  • B. Reboot the VM.
  • C. Configure the Enhanced vMotion Compatibility (EVC) on the VM to Intel Skylake.
  • D. Power on the VM.
  • E. Configure the Enhanced vMotion Compatibility (EVC) on vSphere Cluster A and B to sup-port Intel Skylake.
  • F. Power off the VM.

EVC1 is the new cluster with EVC configured. So you need to configure A and B clusters (E). If the VM was created with a different CPU feature set and has CPU-specific features enabled that don't match the cluster’s EVC setting, applying EVC at the VM level could ensure compatibility. (C) If the VM needs to migrate across clusters with different EVC baselines (e.g., moving from an older cluster to a Skylake cluster), adjusting the VM EVC setting can help enforce compatibility across clusters. (B) Remember that evc1 is running, so only reboot is possible.

Take care, EVC1 isn't a virtual machine: The EVC levels are named to match CPU families and generations, such as Intel “Skylake” or AMD “EPYC.” Setting an EVC mode, like EVC1, simplifies VM migration, as all VMs use only the CPU features available at that compatibility level, making it possible to maintain performance without the risk of hardware-based disruptions. So the only possible choice are C,D, F

I'm sorry. I changed idea. C, E, B. EVC1 is the new cluster with EVC configured. So you need to configure A and B clusters (E). Answer C is mandatory, why? If the VM was created with a different CPU feature set and has CPU-specific features enabled that don't match the cluster’s EVC setting, applying EVC at the VM level could ensure compatibility. If the VM needs to migrate across clusters with different EVC baselines (e.g., moving from an older cluster to a Skylake cluster), adjusting the VM EVC setting can help enforce compatibility across clusters. Then a reboot (B)

I don't understand why E is correct, the question didn't mention that the ECS is enabled on the cluster ?!!

Thats why you need to enable it otherwise the cluster feature wont be active

I agree, this question is confusing. Still not sure what to choose. After reading https://blogs.vmware.com/PowerCLI/2018/05/configuring-per-vm-evc.html I believe the EVC needs to be configured at the VM level so that the EVC configuration migrates with the VM to the other clusters, however, the screenshot is saying it's already enabled, and powered off, not on.

I want to add that this is a weird question. The vm is powered off in the screenshot but the tekst says it is on.

Powered off shows machine state so its enabled on VM - have to disable (a) Cluster has different cpus before. Has to be configured for new Skylakes(e) And of course - power on VM after that (d)

Looking exhibit the VM is already Powered Off so B and F are not correct also EVC are already Enabled so C are not correct so probably correct answers are A D E
