質問 # 54
A developer is trying to deploy a Kubernetes Application into a namespace within a Supervisor Cluster The deployment must utilize the latest assets that have been pushed into the Registry Service.
What should the developer add to the YAML file to ensure that the deployment is successful?
- A. image: <image registry url>/<namespace name>/<image name>:latest
- B. template: <image registry url>/<namespace name>/<image name> : latest
- C. template: /<namespace name>/<image name>:latest
- D. image: /<namespace>/<image name>:latest
正解：A
解説：
* Create an example pod spec with the details about the private registry.
* apiVersion: v1
* kind: Pod
* metadata:
* name: <workload-name>
* namespace: <kubernetes-namespace>
* spec:
* containers:
* - name: private-reg-container
* image: <Registry-IP-Address>/<vsphere-namespace>/<image-name>:<version>
* imagePullSecrets:
* - name: <registry-secret-name>
* Replace <workload-name> with the name of the pod workload.
* Replace <kubernetes-namespace> with the Kubernetes namespace in the cluster where the pod will be created. This must be the same Kubernetes namespace where the Registry Service image pull secret is stored in the Tanzu Kubernetes cluster (such as the default namespace).
* Replace <Registry-IP-Address> with the IP address for the embedded Harbor Registry instance running on the Supervisor Cluster.
* Replace <vsphere-namespace> with the vSphere Namespace where the target Tanzu Kubernetes is provisioned.
* Replace <image-name> with an image name of your choice.
* Replace <version> with an appropriate version of the image, such as "latest".
* Replace <registry-secret-name> with the name of the Registry Service image pull secret that you created previously.
質問 # 55
Which kubectl command should be used to change the active vSphere namespace to namespace-01?
- A. kubectl get ns namespace-01
- B. kubectl config change-context namespace-01
- C. kubectl describe ns namespace-01
- D. kubectl config use-context namespace-01
正解：D
解説：
A context element in a kubeconfig file is used to group access parameters under a convenient name. Each context has three parameters: cluster, namespace, and user. By default, the kubectl command-line tool uses parameters from the current context to communicate with the cluster.
To choose the current context:
kubectl config use-context ctx001
質問 # 56

正解：D
質問 # 57
What is the proper way to delete a Persistent Volume Claim?
- A. By unmounting the volume from the VM and deleting it from the vSphere datastore
- B. By using the kubectl delete persistentvolumeclaim command
- C. By using the kubectl remove pvc command
- D. Through the SPBM policy engine using the vSphere Client
正解：B
質問 # 58
Which command will show the Tanzu Kubernetes cluster versions available in the vSphere content library?
- A. kubect1 get rc,services
- B. kubect1 get contentlibrary
- C. kubect1 get tanzukubernetesreleases
- D. kubect1 get tanzuimages
正解：C
解説：
Explanation
* kubectl get tanzukubernetesreleases
List available Tanzu Kubernetes releases.
* kubectl get tkr
Short form version of the preceding command.
* kubectl get tkr v1.17.8---vmware.1-tkg.1.5417466 -o yaml
Provides details on the named Tanzu Kubernetes release.
VMware Tanzu distributes Kubernetes software versions as Tanzu Kubernetes releases. To consume these releases, you configure a vSphere Content Library and synchronize the available releases. You can do so using a subscription-based model, or on-demand. If you want to provision Tanzu Kubernetes in an internet restricted environment, you can create a local library and manually import the releases.

質問 # 63
Which three elements should be configured by a vSphere administrator after creating vSphere Namespace? (Choose three.)
- A. Namespace name
- B. NSX Segment
- C. License
- D. Storage Policy
- E. Capacity and Usage limits
- F. Permissions
正解：D、E、F
解説：
Creating a Namespace
A vSphere administrator configures permissions and storage before a namespace can be used:
* Assign edit or view permissions to users. Users must be present in a configured single sign-on (SSO) identity source.
* Must assign a VM storage policy to the namespace.
* Can define resource limits (optional).
* Must add a content library to enable the Tanzu Kubernetes Grid Service.
質問 # 64
Where is a storage policy applied to enable Persistent Volumes?
- A. Cluster
- B. Datastore
- C. Virtual Machine
- D. Namespace
正解：D
解説：
Explanation
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.
Developers can list the available storage classes in their namespace by running the kubectl describe ns
<namespace-name> command.

質問 # 71
On which network are TKG clusters deployed in vSphere with Tanzu when using the vSphere networking stack?
- A. Edge
- B. Backend
- C. Frontend
- D. Workload
正解：D
解説：
Explanation
The Workload Network, such as TKGS-VLAN1000, is where the Tanzu Kubernetes clusters run.
A workload network is a network construct that is used by supervisor control plane VMs and vSphere namespaces:
* The workload network is supported by a vSphere Distributed Switch port group.
* An IP range is defined to allocate an IP address for VMs attached to the workload network.
* A primary workload network must be selected.
* The supervisor control plane VMs attach to the primary workload networks port group.
A workload network can be used by multiple namespaces. A namespace can be assigned only one workload network.
