https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-A7756D67-0B95-447D-A645-E2A384BF8135.html 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
Explanation
Tanzu Kubernetes Grid Service CNI
Tanzu Kubernetes Grid Service supports Antrea and Calico as container network interfaces (CNI).
The default CNI in vSphere 7 Update 1 is Antrea.
Antrea is a VMware-supported, open source, Kubernetes-native project that implements the container network interface (CNI) and Kubernetes network policy, providing network connectivity and security for pod workloads. Antrea extends the benefit of programmable networks from Open vSwitch (OVS) to Kubernetes.
For more information about Antrea, see https://antrea.io/
質問 # 44

正解：C
質問 # 45
Which functionality does the Cloud Native Storage (CNS) component take advantage of to support the creation of container volumes?
- A. First Class Disk
- B. VMware Disk Encryption
- C. Storage Based Policy Management
- D. Virtual Disk
正解：A
解説：
The Cloud Native Storage server resides in vCenter Server:
* Provisions and manages life cycle operations for container volumes
* Creates First Class Disks (FCDs) to support the container volumes
* First Class Disks exist as .vmdk and -flat.vmdk files on a vSphere datastore * Integrates with storage policy based management (SPBM) for the placement of disks A First Class Disk (FCD) is also called an improved virtual disk. It is a named virtual disk that is unassociated with a VM. These disks reside on a VMFS, NFS, or vSAN datastore and support container volumes.
Storage policy based management (SPBM) is a vCenter Server service that supports provisioning of persistent volumes according to specified storage requirements. After provisioning, the service monitors compliance of the volume with the required policy characteristics.
質問 # 46
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?
- A. Create a storage policy containing the tagged datastores. and apply it to the vSphere Namespace.
- B. Create a storage class containing the tagged datastores. and apply it to the Supervisor Cluster
- C. Create a persistent volume claim containing the tagged datastores, and apply it to the vSphere Namespace.
- D. Create a storage Policy containing the tagged datastores. and apply it to the Supervisor Cluster.
正解：A
解説：
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.

質問 # 52
How does Kubernetes implement the vSphere storage policy in vSphere with Tanzu?
- A. Static Persistent Volume
- B. Storage class
- C. Paravirtual CSl
- D. Persistent Volume
正解：B
解説：
When vSphere with Tanzu converts storage policies that you assign to namespaces into Kubernetes storage classes, it changes all upper case letters into lower case and replaces spaces with dashes (-). To avoid confusion, use lower case and no spaces in the VM storage policy names.
Storage Policy Based Management is a vCenter Server service that supports provisioning of persistent volumes and their backing virtual disks according to storage requirements described in a storage policy.

- A. NSX-T
- B. WeaveNet
- C. Antrea
- D. Cillium
正解：A、C
解説：
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.
質問 # 56
Which statement describes a characteristic of Supervisor Cluster control plane VMs?
- A. Manage the lifecycle of ESXi hosts
- B. Run system and infrastructure pods
- C. Are manually created by a vSphere administrator
- D. Host developer workloads
正解：B
解説：
Explanation
The Supervisor Cluster provides the management layer on which Tanzu Kubernetes clusters are built. The Tanzu Kubernetes Grid Service is a custom controller manager with a set of controllers that is part of the Supervisor Cluster. The purpose of the Tanzu Kubernetes Grid Service is to provision Tanzu Kubernetes clusters.
While there is a one-to-one relationship between the Supervisor Cluster and the vSphere cluster, there is a one-to-many relationship between the Supervisor Cluster and Tanzu Kubernetes clusters. You can provision multiple Tanzu Kubernetes clusters within a single Supervisor Cluster. The workload management functionality provided by the Supervisor Cluster gives you control over the cluster configuration and lifecycle, while allowing you to maintain concurrency with upstream Kubernetes.
