A Platform Engineer is managing a stateful application running on a TKG cluster. The application's data volume (db-data) is running out of space. The underlying vSphere Storage Policy supports expansion.
Review the PVC definition:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: db-data
namespace: app-prod
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 10Gi
storageClassName: gold-policy
Which steps are required to resize this volume to 20Gi without downtime? (Choose 2.)

• A.Run kubectl patch pvc db-data -n app-prod -p '{"spec": {"resources": {"requests": {"storage":
  "20Gi"}}}}'.
• B.Edit the gold-policy in vCenter Server to increase the capacity.
• C.The pod using the volume must be manually deleted and recreated to trigger the resize.
• D.The vSphere CSI driver will automatically detect the spec change, resize the virtual disk (VMDK) on the backend vSphere storage, and then resize the filesystem inside the pod (if online resizing is supported by the guest OS/filesystem).
• E.Delete the PVC and recreate it with storage: 20Gi, then restore data from backup.

A Platform Engineer is optimizing the IP address consumption of the NSX Advanced Load Balancer (Avi) used by a Supervisor Cluster. The current "Essentials" edition deployment consumes a new Service Engine (SE) IP and a VIP for every LoadBalancer service, leading to IP exhaustion.
The engineer wants to switch to a design where multiple Kubernetes Services share the same Service Engine group and potentially consolidate VIPs where possible (using L7 Ingress), but the immediate concern is the backend SE scaling.
Review the current setting: Service Engine Group: Default-Group Max VS per SE: 10 What configuration change on the Avi Controller would optimize resource usage for this VKS deployment? (Select all that apply.)

• A.Configure the IPAM Profile to use a larger subnet.
• B.Use AKO (Avi Kubernetes Operator) features to implement L7 Ingress (sharing a single VIP/VS for multiple apps) instead of creating a type: LoadBalancer (L4) for every app.
• C.Switch the Supervisor configuration to use HAProxy, which is more efficient.
• D.Increase the Max Virtual Services per Service Engine limit in the Service Engine Group settings (e.g., to 50 or 100), allowing more services to be packed onto existing SEs before spawning new ones.
• E.Enable NSX-T Cloud mode in Avi instead of vCenter Cloud mode.

A Platform Engineer needs to provide a custom Virtual Machine Class to the Data Science team.
They require a VM with exactly 16 vCPUs and 64 GB of RAM for a specific model training workload. The default classes do not match these specifications.
Which sequence of steps allows the engineer to make this specific configuration available to the team's namespace? (Choose 2.)

• A.Assign the newly created Custom VM Class to the Data Science team's vSphere Namespace.
• B.Edit the TKG cluster YAML to override the default node sizing manually.
• C.Create a new "VM Class" object in the vSphere Client under "Workload Management" > "Services" >
  "VM Service", defining the specific CPU and Memory reservations.
• D.Create a vSphere Resource Pool with the limits set to 16 vCPU / 64 GB RAM and assign it to the namespace.
• E.Modify the existing guaranteed-large class to match the new requirements.

A Platform Engineer needs to enable the Cluster Autoscaler for an existing TKG cluster named web- cluster to handle bursty traffic. The cluster currently has a static worker node count.
Review the TanzuKubernetesCluster YAML snippet:
spec:
topology:
workers:
replicas: 3
vmClass: best-effort-medium
storageClass: default-storage
Which modification to the YAML manifest correctly enables autoscaling for the worker node pool?

• A.Change the replicas field to auto.
• B.Create a HorizontalPodAutoscaler resource targeting the MachineSet.
• C.Install the cluster-autoscaler Helm chart from the VMware marketplace into the cluster.
• D.Add the annotations cluster.k8s.io/cluster-api-autoscaler-node-group-min-size and cluster.k8s.io/cluster-api-autoscaler-node-group-max-size to the workers section (or the corresponding MachineDeployment).
