Correct Answer:

Explanation:
LUN Masking = A security process performed on the storage array by which specific storage components are hidden to prevent unauthorized access to data; Datastore Cluster = A collection of shared resources with a shared management interface that enables resource allocation policies; SAN Fabric = A dedicated high-performance network infrastructure for storage devices; Datastore = A manageable storage entity used as a repository for Virtual Machine files including log files, scripts, configuration files and virtual disks; Host Bus Adapter (HBA) = Added to an ESX host server to allow the host access to the dedicated storage area network; Zoning = A security process completed on the Storage Area Network to ensure only certain devices can communicate with each other.
These definitions describe the core components of a Fibre Channel SAN design in a VCF Workload Domain. LUN masking is performed on the storage array and controls which hosts can see specific LUNs, preventing unauthorized access to storage. A datastore cluster is a collection of datastores managed as a shared resource pool, allowing placement and balancing policies through Storage DRS. A SAN fabric is the dedicated high-performance network that interconnects ESX hosts, Fibre Channel switches, and storage arrays. A datastore is the vSphere logical storage container where VM configuration files, virtual disks, logs, and related files reside. A Host Bus Adapter is the physical or virtual adapter in the ESX host that connects the host to the Fibre Channel storage area network.
Zoning is performed on the Fibre Channel fabric and controls which initiators and targets can communicate. Together, zoning and LUN masking provide layered access control, while datastores and datastore clusters provide the vSphere consumption model.

Correct Answer:

Explanation:
Full Clone from Volume Snapshot
4kn Support
Online Volume Expansion
Offline Volume Expansion
Static Persistent Volume
VMware Kubernetes Service persistent volumes use vSphere storage integrations such as CNS and pvCSI to provide Kubernetes storage services backed by vSphere datastores and storage policies. The supported persistent volume capabilities include Static Persistent Volume, which allows pre-existing storage to be consumed by Kubernetes workloads; Offline Volume Expansion and Online Volume Expansion, which allow persistent volumes to be resized depending on workload and filesystem state; Full Clone from Volume Snapshot, which enables a new volume to be created from an existing snapshot; and 4kn Support, which supports modern 4K native storage devices where the underlying stack supports them. Storage vMotion with attached Persistent Volumes is not supported because moving an attached Kubernetes persistent volume while it is in active use can break attachment and consistency assumptions. Storage DRS is also not a supported persistent volume capability in this VKS context. Flash Read Cache is not part of the supported VKS persistent-volume capability set.

Correct Answer:

Explanation:
ESA evaluates available capacity and fault domains to satisfy policy compliance.
vSAN detects the failure and marks affected objects as non-compliant.
Resync completes and objects transition to Compliant status.
New components are instantiated on eligible capacity devices, and resync begins.
A failed NVMe device in a vSAN ESA cluster is handled as a storage pool device failure. vSAN first detects the failure and marks affected objects as non-compliant when their assigned storage policy requirements are no longer satisfied. ESA then evaluates available capacity and fault domains to determine whether replacement components can be placed in a way that restores compliance. If sufficient placement resources exist, vSAN creates new components on eligible capacity devices and begins resynchronization. After the resync completes, the affected objects transition back to Compliant status. The Repair Delay Timer is primarily associated with absent components, such as a host or device that may return, and is not the required step for a permanent NVMe failure. The administrator does not have to manually trigger Repair Objects Immediately for the normal automatic repair process. A full cluster rebalance is separate from repair and is not performed before rebuilding missing or degraded components.
