NEW QUESTION 10
A Storage Administrator is performing a post-deployment validation on a VCF 9.0 Workload Domain.
The design utilized the vSAN Sizer tool to forecast capacity for a 6-node Stretched Cluster (3 nodes per site).
The Sizer output predicted a specific “Free Capacity” based on an FTT=1 (RAID-1) Local + Dual Site Mirroring policy.
The administrator queries the cluster object distribution using the Ruby vSphere Console (RVC) to verify if the actual component layout matches the Sizer’s assumptions.
“`
[RVC Output: vsan.obj_status_report ~cluster]
Object Type: Virtual Disk (hard disk 1)
Policy: PFTT=1 (Mirror), SFTT=1 (RAID-1)
Component Layout:
Site A:
– Component 1: 50 GB (Active)
– Component 2: 50 GB (Active)
– Witness: 4 KB (Active)
Site B:
– Component 3: 50 GB (Active)
– Component 4: 50 GB (Active)
– Witness: 4 KB (Active)
Witness Site:
– Witness: 4 KB (Active)
“`
Why does this RVC output validate that the Sizer tool correctly estimated a 4.0x capacity overhead for this object, and how does this affect cluster expansion planning? (Select all that apply.)

NEW QUESTION 16
An Operations Engineer is diagnosing a failure in the VCF “Add Host” workflow for an HCI Workload Domain. The workflow successfully added the ESXi host to the vSphere cluster but failed during the storage claiming phase.
The engineer queries the vSAN disk configuration status on the target host via RVC:
“`
[RVC Output: vsan.host_info ~host]
Host: esx-10.corp.local

NEW QUESTION 17
An administrator has been tasked with adding supplemental storage to an existing VMware Cloud Foundation (VCF) Workload Domain. The supplemental storage will add capacity for backup data and ISO images without impacting the principal storage used for live production workloads.
What should the administrator recommend meeting the requirement?

NEW QUESTION 18
An administrator has been tasked with making changes to a VMware Cloud Foundation (VCF) Workload Domain cluster that is configured with NFS for both Principal storage and Supplemental storage.
The cluster has the following configuration:
* There are 3 x ESX host servers.
* There are 3 x NFS Datastores allocated to host Virtual Machines workloads.
* There is a single NFS Datastore allocated for hosting ISO files.
The administrator has the following concerns with the existing configuration:
* Every time a new Virtual Machine is deployed to the Workload Domain, the administrator must choose which datastore should be used.
* When reviewing the Datastores in VCF Operations:
* One of the datastores has no Virtual Machines running in it.
* The other two datastores have an imbalance of Virtual Machines and this is causing resource contention. The administrator has the following requirements: * Virtual Machines must be placed automatically on the most appropriate datastore based on utilization. * Migration recommendations on Virtual Machine placement should be made when one datastore reaches 50% utilization. * Virtual Machines must only be migrated to another datastore after being approved by an administrator. What four actions must the administrator take to meet all of the requirements? (Choose four.)

NEW QUESTION 19
An administrator is presented with the following scenario:
* 20 TB of additional storage is being requested by a VM application owner.

* The existing vSAN cluster only has 10 TB of unused capacity.
* The hosts in the cluster have no additional NVMe slots left.
* The administrator does not have permission to purchase additional hosts or re-assign hosts from other vSAN clusters.
* Other vSAN clusters exist in the environment that can satisfy the requirement.
Which vSAN feature should be used to fulfill this scenario?
