Question 5

Which two considerations needs to be made when deciding on a virtual machine class type during the process of creating a Tanzu Kubernetes cluster? (Choose two )

Answer Options
Correct Answer: A, C
Explanation

A virtual machine class is a request for resource reservations for processing power on the virtual machine (VM), including CPU and memory (RAM). For example, the VM class type named 'guaranteed-large' reserves 4 CPU and 16 GB RAM. SeeDefault Virtual Machine Classesfor a list of default VM classes and their corresponding CPU and RAM reservations.

The VM disk size is set by the OVA template, not the VM class definition. For Tanzu Kubernetes releases, the disk size is 16GB. SeeAbout Tanzu Kubernetes release Distributions.

There are two reservation types for VM classes: guaranteed and best effort. The guaranteed class fully reserves its configured resources. This means that for a given cluster thespec.policies.resources.requestsmatches thespec.hardwaresettings. The best effort class allows resources to be overcommitted. For production workloads it is recommended that you use the guaranteed VM class type.
