Which two items must be provided before a vSphere with Tanzu Supervisor Namespace can be created? (Choose two.)
Explanation:
Prerequisites
Configure a cluster with vSphere with Tanzu.
Create users or groups for all DevOps engineers who will access the namespace.
Create storage policies for persistent storage. Storage policies can define different types and classes of storage, for example, gold, silver, and bronze.
Create VM classes and content libraries for stand-alone VMs.
Create a content library for Tanzu Kubernetes releases for use with Tanzu Kubernetes clusters.
See Creating and Managing Content Libraries for Tanzu Kubernetes releases.
Required privileges:
Namespaces.Modify cluster-wide configuration
Namespaces.Modify namespace configuration

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 )
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.
Question 63

What is true of a Tanzu Kubernetes Cluster?
Explanation:
Tanzu Kubernetes Cluster is a Kubernetes cluster deployed by developers using a YAML specification file. It uses resources from hosts across vSphere clusters to form a Kubernetes cluster on vSphere. It also enables vSphere High Availability and Distributed Resource Scheduler, which allows for load balancing and high availability of resources in the cluster. It does not remove the Kubernetes API for use by DevOps teams.
Question 64

Which container network interface (CNI) is supported with Tanzu Kubernetes clusters created by the Tanzu Kubernetes Grid Service? (Choose two )
Explanation:
The container network interfaces (CNIs) supported with Tanzu Kubernetes clusters created by the Tanzu Kubernetes Grid Service are NSX-T and Antrea. NSX-T is a multi-cloud networking and security platform from VMware that provides built-in container networking and security capabilities. Antrea is an open-source CNI project created by the GitHub team that provides network policy enforcement for Kubernetes clusters. Both of these CNIs provide support for multi-tenancy and advanced network policy enforcement.

An administrator needs to configure a Supervisor Cluster with the vSphere networking stack (vSphere Distributed Switch) and HAProxy appliance using default configuration. The administrator has already connected all hosts in the cluster to a vSphere Distributed Switch and created distributed portgroups.
Which designation must be mapped to a distributed portgroup?
