Namespaces
etcd instance
Worker node count
ReplicaSets

Answer(s): C

QUESTION: 7

Which two container network interfaces (CNIs) are supported with Tanzu Kubernetes clusters created by the Tanzu Kubernetes Grid Service? (Choose two)

NSX-T
Weave Net
Flannel
Antrea
Calico

Answer(s): D,E

Explanation:

A Tanzu Kubernetes cluster provisioned by the Tanzu Kubernetes Grid Service supports two CNI options: Antrea (default) and Calico. Both are open-source software that provide networking for cluster pods, services, and ingress.
Tanzu Kubernetes clusters provisioned by the Tanzu Kubernetes Grid Service support the following Container Network Interface (CNI) options: Antrea Calico

QUESTION: 8

Where are the virtual machine images stored that are used to deploy Tanzu Kubernetes clusters?

Content Library
Supervisor Cluster
Harbor Image Registry
Namespace

Answer(s): C

Explanation:

You can use the embedded Harbor Registry to serve as the private container registry for images that you deploy to Tanzu Kubernetes clusters provisioned by the Tanzu Kubernetes Grid Service.
vSphere with Tanzu embeds a Harbor Registry instance that you can enable on the Supervisor Cluster and use to deploy container-based workloads to Tanzu Kubernetes clusters.

Once the embedded Harbor Registry is enabled on the Supervisor Cluster, the Tanzu Kubernetes Grid Service will install onto the Tanzu Kubernetes cluster nodes the root CA certificate for the registry instance. This certificate is installed on both new clusters and on existing clusters (by way of a reconciliation loop). From there you can run images on the cluster by specifying the private registry in the workload YAML.
