NEW QUESTION # 25
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 )
- A. The storage classes which need to be made available to the cluster
- B. The amount of CPU. memory, and storage the virtual machine should have
- C. Connectivity between the Tanzu Kubernetes cluster and the Subscribed Content Library
- D. Whether the resources provided by the virtual machine class type should be reserved on the host
- E. The configuration parameters which need to be edited in the cluster
Answer: B,D
Explanation:
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. See Default Virtual Machine Classes for 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. See About 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 the spec.policies.resources.requests matches the spec.hardware settings. The best effort class allows resources to be overcommitted. For production workloads it is recommended that you use the guaranteed VM class type.

VMware Harbor Registry
VMware Harbor Registry is an enterprise-class registry server that stores and distributes container images.
Harbor allows you to store and manage images for use with VMware Tanzu Kubernetes Grid Integrated Edition (TKGI).

The creation of which object by an administrator in the vSphere client automatically results in the creation of a new segment within NSX -T?
- A. Service
- B. Pod
- C. Network policy
- D. Namespace
Answer: D
Explanation:
NSX Container Plugin (NCP) runs as a pod on the control plane VMs. It listens for requests for network objects to the API server and interfaces with the NSX Manager to create, update, or delete those objects:
* A request to create a namespace results in a new NSX segment.
* A request to deploy a pod results in a segment port request and IP assignment.
* A request to create a service results in a new virtual server.
* A request to create a network policy results in a new distributed firewall rule.
