VMware Advanced VMware Cloud Foundation 9.0 Storage Sample Questions:

1. An administrator is managing a stretched vSAN ESA cluster where each site has three hosts.
The following parameters apply to the storage policy being configured at the datastore level:
* The policy is configured at the datastore level
* Site disaster tolerance = Site mirroring - stretched cluster
* Failures to tolerate = 1 failure - RAID-1 (mirroring)
* Number of disk stripes = 1
When inspecting some of the Virtual Machines (VMs), why do objects have 3 disk stripes?

A) Site mirroring has been configured.
B) There is a policy configured at the Virtual Machine level.
C) Each Virtual Machine has 3 objects.
D) ESA in RAID-1 always uses 3 stripes.

2. 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.)

A) Configure the Datastore Cluster to use Fully Automated Storage DRS.
B) Create a new Datastore Cluster using all four available Datastores.
C) Configure the Datastore Cluster to use Manual Storage DRS.
D) Configure the Datastore Cluster to set the Storage DRS storage space threshold to 50%.
E) Ensure all three NFS Datastores are available to each ESX host server.
F) Configure the Datastore Cluster to set the Storage DRS storage space utilization difference to 50%.
G) Create a new Datastore Cluster using all three NFS Datastores allocated to host Virtual Machines workloads.

3. An administrator is tasked with designing a highly available vSAN ESA two-node cluster for a remote VMware Cloud Foundation (VCF) workload domain. The solution should be able to survive the failure of any disk group in addition to a host failure without data loss.
What is the minimum total number of nested fault domains required for the design?

A) 6
B) 4
C) 7
D) 2

4. An administrator is managing a local vSAN 3-node cluster running the Express Storage Architecture (ESA) as part of a VMware Cloud Foundation (VCF) Workload Domain.
The following parameters apply at the cluster level:
* HA is enabled
* Reserved Failover Capacity = 25% for both CPU and Memory
The administrator is tasked with configuring the VSAN storage policy so it will tolerate the maximum number of failures.
What two protection levels can the administrator configure? (Choose two.)

A) RAID-I (Mirroring) 2 Failures.
B) RAID-5 (Erasure Coding) 1 Failure.
C) RAID-I (Mirroring) 3 Failures.
D) RAID-1 (Mirroring) 1 Failure.
E) RAID-6 (Erasure Coding) 2 Failures.
F) No data redundancy.

5. An enterprise is planning to deploy a new vSAN ESA enabled cluster to their existing VMware Cloud Foundation (VCF) Private Cloud Workload Domain. The following requirements have been given:
* 2 x 4 TB NVMe disks per host
* FTT=1/RAID-5 for all deployed Virtual Machines
* Expected dedupe/compression ratio = 1.5 (50%)
* Reserve enough capacity to rebuild a host completely in case of a failure (Host Rebuild Reservation)
* Operational Reserve of 10%
* Expected overhead for filesystem, object, etc. of 25%
How many hosts are required to meet a minimum usable capacity of 12 TB?

A) 3 hosts
B) 5 hosts
C) 6 hosts
D) 4 hosts
