A DevOps engineer is attempting to deploy a new Tanzu Kubernetes Cluster (TKC) into a vSphere Namespace. The deployment fails with an error message indicating 'no suitable VM class found'. The engineer has confirmed that multiple VM classes are defined in the Supervisor Cluster. What is the most likely cause of this issue?
A platform operator needs to provide developers with different T-shirt sizes for Tanzu Kubernetes Cluster nodes (e.g., small, medium, large). Which two components must be configured to achieve this? (Select TWO)
True or False: When using vSphere with Tanzu with the vSphere Distributed Switch (VDS) for networking, a third-party IPAM provider is required for managing IP addresses for vSphere Pods.
**Company Background:** A financial technology company, FinCorp, is modernizing its monolithic trading application by breaking it down into containerized microservices. They have chosen vSphere with Tanzu to leverage their existing VMware expertise and infrastructure. The environment is configured with NSX-T for advanced networking and security. **Current Situation:** The security team has mandated strict network isolation between the different microservices. Specifically, the 'order-processing' service should only be able to communicate with the 'trade-execution' service on TCP port 8080, and the 'trade-execution' service should only be able to initiate communication with the 'market-data' service on TCP port 9000. All other pod-to-pod communication within the namespace must be denied by default. **Requirement:** As the vSphere administrator, you must implement a solution using native Kubernetes objects that enforces this traffic flow policy within the 'trading-app' vSphere Namespace. Which approach satisfies the security requirement?
A vSphere administrator is enabling Workload Management and must choose a networking stack. The existing environment uses a vSphere Distributed Switch (VDS) and the primary requirement is to get the Supervisor Cluster operational with minimal changes to the existing network infrastructure. Which component provides load balancing for Kubernetes services in this configuration?
The command `kubectl vsphere login --server= --tanzu-kubernetes-cluster-name --vsphere-username ` is used to authenticate to a Tanzu Kubernetes Cluster. Where does the resulting authentication context get stored?
A developer needs to deploy a stateful application that requires 50 GiB of high-performance storage. The vSphere administrator has created a storage policy named 'fast-ssd' which is backed by an all-flash vSAN datastore. How can the developer request storage that adheres to this policy for their application?
What is the primary role of the Spherelet component running on each ESXi host in a Supervisor Cluster?
An administrator needs to update the Kubernetes version of a running Tanzu Kubernetes Cluster (TKC). Which is the correct procedure to perform this upgrade in a supported manner?
A vSphere administrator has enabled the Harbor Image Registry service on a Supervisor Cluster. A developer reports that they are unable to push container images to the registry, receiving an 'authentication required' error. The developer is a member of a group that has 'Edit' permissions on the vSphere Namespace. What is the most likely reason for this failure?
