An administrator working in a vSphere with Tanzu environment wants to ensure that all persistent volumes configured by developers within a namespace are placed on a defined subset of datastores The administrator has applied tags to the required datastores in the vSphere Client
Which action should the administrator take next to meet the requirement?
The vSphere administrator defines and assigns VM storage policies to a namespace:
* VM storage policies are translated into Kubernetes storage classes.
* Developers can access all assigned VM storage policies in the form of storage classes.
* Developers cannot manage storage classes.
Storage class names are created in the following way:
* Spaces in VM Storage Policy names are replaced with hyphens (-).
* Special characters are replaced with a digit. A VM Storage Policy called My Gold Policy $ is called my-gold-policy-0 as a storage class.
Which capability do persistent volumes provide to containerized applications?
Certain Kubernetes workloads require persistent storage to store data permanently. To provision persistent storage for Kubernetes workloads, vSphere with Tanzu integrates with Cloud Native Storage (CNS), a vCenter Server component that manages persistent volumes.
Persistent storage is used by vSphere Pods, Tanzu Kubernetes clusters, and VMs. The following example illustrates how persistent storage is used by a vSphere Pod.
vSphere Pods use different types of storage depending on the objects that are stored. The types of storage are ephemeral virtual machine disks (VMDKs), persistent volume VMDKs, and containers image VMDKs:
* Storage policies for container image and ephemeral disks are defined at the cluster level.
* Storage policies for persistent volumes are defined at the namespace level.
* Networking for vSphere Pods uses the topology provided by NSX.
An administrator is tasked with increasing the amount of CPU and memory in an existing Tanzu Kubernetes cluster.
Which change must the administrator complete to ensure the cluster scales successfully when updating the YAML definition?
Virtual Machine Class Types for Tanzu Kubernetes Clusters
A virtual machine class defines the resource sizing for Tanzu Kubernetes cluster VMs: * CPU * Memory *
Storage
Virtual machine class types range from extra small (xsmall) to extra large (xlarge). Class types are categorized as guaranteed or best effort:
* Guaranteed: Reserve all CPU and memory allocations. * Best effort: Allocate the same CPU and memory but do not reserve the resources.
The class type guaranteed-small allocates 2 CPU, 4 GB of memory, and 16 GB of storage and reserves CPU and memory allocations. Custom virtual machine class types cannot be defined.
What provides a declarative, Kubernetes-style API for cluster creation, configuration, and management?
Which command displays the storage limits that have been set together with the amount of resources consumed?
Create the ResourceQuota:
kubectl apply -f https://k8s.io/examples/admin/resource/quota-mem-cpu.yaml --namespace=quota-mem-cpu-example
View detailed information about the ResourceQuota:
kubectl get resourcequota mem-cpu-demo --namespace=quota-mem-cpu-example --output=yaml
