C and E "which two data sources with peak and average utilization data are required for sizing" Only CPU and IOPS provide peak and average values. You could get them using for example vRealize Operations Manager.

For me is C and E becouse the question is "data source to peak and average" And CPU and IOPS they give you that.

Selected Answer: CE

C & E are the only metrics that are useful for sizing. %Ready, Disk latency, and Ballooning are contention metrics and depend on the previous hardware.

C and E , as that provides peak and average utilisation and is used for sizing purposes and ESXi density calculations

B and E is correct. A,C,D is about CPU/Memory, but since vCPU/Memory configuration data is already provided, you won't need it unless the environment is severely overprovisioned. IOPS, Disk write latency is important if you have multiple datastores with different specs such as Ahttps://www.examtopics.com/exams/vmware/3v0-2121/view/5/#ll-flash/HDD based storage.

The question states "An inventory of the existing infrastructure, including configured vCPU, RAM and storage sizes has been provided." but does not say utilization data has been provided.

I agree, you already has the amount of CPU and memory you will need, and how much you increase it but you need to know how storage behaves, most if it will be vSAN and what policies you'll use for the storage

Provided is the vCPU configuration not the utilization. Therefore, need to consider CPU utilization for sizing. So the answer is C & E

I am changing my answer to C and E, Because in the Vmware Vsphere document wrote: For each system, capture peak and average utilization for the following items: • CPU • RAM •IOPS • Network utilization https://sysarticles.com/vmware-vsphere-analyzing-the-current-state/
