2V0-71.23 Exam Dumps : VMware Tanzu for Kubernetes Operations Professional

Antrea is the default CNI for new Tanzu Kubernetes Grid workload clusters8. Antrea is an open-source Kubernetes networking solution that implements the Container Network Interface (CNI) specification and uses Open vSwitch (OVS) as the data plane9. Antrea supports various features such as network policies, service load balancing, NodePortLocal, IPsec encryption, IPv6 dual-stack, and more10.

The other options are incorrect because:

• Multus CNI is an open-source container network interface plugin for Kubernetes that enables attaching multiple network interfaces to pods11. It is not the default CNI for Tanzu Kubernetes Grid workload clusters.
• Flannel is an open-source simple and easy-to-use overlay network that satisfies the Kubernetes requirements12. It is not the default CNI for Tanzu Kubernetes Grid workload clusters.
• Calico is an open-source network and network security solution for containers, virtual machines, and native host-based workloads13. It is not the default CNI for Tanzu Kubernetes Grid workload clusters.

The command that can be used to upgrade a VMware Tanzu Kubernetes Cluster that is managed by VMware Tanzu Mission Control is tmc cluster upgrade [version] . This command allows you to upgrade a managed cluster to a newer version of Kubernetes that is supported by Tanzu Mission Control5. The version flag is optional and specifies the target version of Kubernetes. If not specified, the command upgrades the cluster to the latest available version5. The clustername argument is required and specifies the name of the cluster to upgrade5.

Cluster API is a Kubernetes project that provides declarative APIs for cluster creation, configuration, and management. Cluster API uses a set of custom resource definitions (CRDs) to represent clusters, machines, and other objects. Cluster API also relies on providers to implement the logic for interacting with different infrastructure platforms. VMware Tanzu Kubernetes Grid uses Cluster API to deploy and manage Kubernetes clusters on various platforms. The three Cluster API providers being used in VMware Tanzu Kubernetes Grid are:

• CAPZ: Cluster API Provider for Azure. This provider enables Cluster API to create Kubernetes clusters on Microsoft Azure4.
• CAPV: Cluster API Provider for vSphere. This provider enables Cluster API to create Kubernetes clusters on vSphere 6.7 or later5.
• CAPA: Cluster API Provider for AWS. This provider enables Cluster API to create Kubernetes clusters on Amazon Web Services5.
