質問 # 17
Which is a valid version change for a Tanzu Kubernetes cluster running Kubernetes version 1.16.7?
- A. Upgrade two minor versions (e.g., 1.18.0)
- B. Upgrade one minor version (e.g.. 1.17.0)
- C. Downgrade one patch version (e.g.. 1.16.5)
- D. Upgrade one major version (e.g.. 2.0.1)
正解：B
解説：
Be aware of the following constraints when upgrading your cluster.
You can upgrade a cluster up to one minor version of Kubernetes from its current version. If necessary, you can perform subsequent upgrades to move the version forward.
Upgrading your version of Kubernetes is a one-way operation. You cannot subsequently downgrade the Kubernetes version, or undo an upgrade.
質問 # 18
Where are the virtual machine images stored that are used to deploy Tanzu Kubernetes clusters?
- A. Content Library
- B. Namespace
- C. Supervisor Cluster
- D. Harbor Image Registry
正解：A
解説：
The vSphere administrator configures a Subscribed Content Library on the Supervisor Cluster. The virtual machine image that is used for the Tanzu Kubernetes cluster nodes is pulled from this library. A Subscribed Content Library originates from a Published Content Library. After the subscription is created, the system synchronizes it with the published library. To create the Tanzu Kubernetes cluster nodes, VMware publishes a Photon OS OVA library to which you subscribe. After the subscriber is synchronized with the publisher, you associate the content library with the Supervisor Cluster.
質問 # 19

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

Explanation
VMware created Harbor in 2014. Harbor was shared with the community through an open-source license in 2016 and donated to the Cloud Native Computing Foundation (CNCF) in 2018.
Harbor is integrated into VMware products: vSphere Integrated Containers, Tanzu Kubernetes Grid Integrated Edition, and vSphere with Tanzu. The embedded Harbor for vSphere with Tanzu includes the following features: * Identity integration and role-based access control
* Graphical user interface
* Auditing of operations
* Management with labels
質問 # 33
What is the proper way to delete a Persistent Volume Claim?
- A. By using the kubectl delete persistentvolumeclaim command
- B. By unmounting the volume from the VM and deleting it from the vSphere datastore
- C. Through the SPBM policy engine using the vSphere Client
- D. By using the kubectl remove pvc command
正解：A
解説：
Also, kubectl delete pvc, which is much shorter.
DevOps engineers create persistent volume claims to request persistent storage resources. The request provisions a persistent volume object and a matching virtual disk. In the vSphere Client, the persistent volume claim manifests as an FCD virtual disk that can be monitored by vSphere administrators.
The claim is bound to the persistent volume. The workloads can use the claim to mount the persistent volumes and access storage.
When the DevOps engineers delete the claim, the corresponding persistent volume object and the provisioned virtual disk are also deleted.
質問 # 34
Which role should the vSphere administrator apply for the developer?
- A. Assign the developer user with the 'VSphere Kubernetes Manager" role at the cluster object.
- B. Assign the developer user with the 'VSphere Kubernetes Manager" role at the vSphere Namespace object.
- C. Assign the developer user with the "can edit" role at the vSphere Namespace object.
- D. Assign the developer user with the "can edit" role at the cluster object.
正解：C
解説：
Permissions for programmers should be assign at the Namespace level, typically using groups and roles.
You assign roles for the Namespace to Active Directory groups. You can later assign access to users by adding them to these groups. You assign access to separate Active Directory groups for the edit and view roles in the Namespace.
