VMware Advanced VMware Cloud Foundation 9.0 Storage 認定 3V0-23.25 試験問題:
1. An architect is presented with the following requirements for the storage solution in a VMware Cloud Foundation (VCF) Workload Domain.
The solution must:
* Allow for rapid recovery in case of an availability zone failure.
* Provide an extremely high amount of IOPS to all applications.
* Allow for additional storage to be added as application needs grow.
* Provide the lowest latency possible for configured applications.
* Provide recovery in case of datastore failure.
* Encrypt data in transit and at rest.
What two vSAN advanced technologies must be deployed to meet these requirements? (Choose two.)
A) vSAN Stretched Clusters
B) vSAN Data Protection Service
C) vSAN Storage Cluster
D) vSAN iSCSI Target Service
E) vSAN File Service
2. An administrator is tasked designing a vSAN storage solution while respecting the following requirements:
* Must use vSAN ESA
* Must be stretched between two data centers
* Must configure Failures to tolerate = 1
* Must configure Erasure Coding
How many components per Virtual Machine (VM) will be created?
A) 4
B) 1
C) 2
D) 3
3. A customer attaches an external Fibre Channel (FC) VMFS datastore to a VMware Cloud Foundation (VCF) workload domain for backup staging. The administrator must confirm that the datastore is visible to all hosts, and that path and device health alarms will trigger should a fabric link or path fail.
Which action should the administrator take to verify this?
A) Use esxcli fc adapter list followed by vmkfstools --inspectpaths to validate health for the VMFS LUN.
B) Execute storage.monitor.getStatus via VCF SDK to receive a consolidated health summary of all VMFS, vSAN and NFS datastores.
C) In vCenter verify the external VMFS datastore connectivity, paths and multipath health.
D) Run esxcli vsan storage list on each host to view VMFS datastore path status.
4. An administrator is troubleshooting a vSAN performance issue. In the vSAN cluster performance charts there is a high latency on the vSAN cluster.
What is a possible cause of the performance issue?
A) Jumbo frames are enabled on the VMkernel adapters.
B) There is congestion in one or more disk groups.
C) Erasure Coding is disabled in the storage policy.
D) The Virtual Machines are using PVSCSI controllers.
5. An administrator is working on a VMware Cloud Foundation (VCF) Workload Domain that was configured to use vSAN for principal storage. The administrator wishes to create and configure a datastore cluster to host tenant VMs using that vSAN backed storage across multiple clusters, mixed OSA and ESA, in the domain.
What should the administrator consider?
A) When using vSAN as the underlying datastore, an administrator must create the datastore cluster via vCenter APIs, include the vSAN datastore(s) in it, enable Storage DRS, and ensure the VM Storage Policies reference the appropriate vSAN-capable datastore.
B) When using vSAN datastores, Datastore Clusters are not supported. Each VM must be placed manually on the vSAN datastore.
C) vSAN OSA and ESA based datastores must be added to a datastore cluster tag and then selected as part of a single storage policy.
D) A datastore cluster can combine different storage types, such as vSAN, FC, and NFS datastores, as long as they are in the same vCenter; Storage DRS will treat them uniformly.
