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.In vCenter verify the external VMFS datastore connectivity, paths and multipath health.
• B.Execute storage.monitor.getStatus via VCF SDK to receive a consolidated health summary of all VMFS, vSAN and NFS datastores.
• C.Use esxcli fc adapter list followed by vmkfstools --inspectpaths to validate health for the VMFS LUN.
• D.Run esxcli vsan storage list on each host to view VMFS datastore path status.

An administrator has been tasked with modifying an existing vSAN File Services deployment which uses Active Directory for Kerberos authentication.
Select three settings which can be modified after initially configuring the vSAN File Services. (Choose three.)

• A.Active Directory Username
• B.Primary IP addresses
• C.Active Directory domain
• D.Organizational Unit
• E.Static IP addresses
• F.DNS names

An administrator needs to monitor an external NFS datastore attached to a VMware Cloud Foundation (VCF) cluster to confirm that it meets latency and throughput targets.
Drag and drop the three correct options to monitor NFS performance from the Options list on the left and place them into the Valid Actions on the right in any order. (Choose three.)

正解：

Explanation:
Run the esxcli storage nfs list command.
Use vCenter Datastore Performance view to monitor NFS datastore latency, IOPS and throughput.
Create a vCenter performance alarm for "Datastore Latency (NFS)" to trigger when thresholds are exceeded.
The correct monitoring workflow is to verify NFS datastore presentation at the host layer, then use vCenter performance views and alarms for operational monitoring. The esxcli storage nfs list command confirms that the NFS datastore is mounted and visible to the ESX host, which is the first validation point before any performance assessment. vCenter Datastore Performance views provide the correct datastore-level telemetry for latency, IOPS, and throughput, including NFS-backed datastores.
Creating a vCenter performance alarm for NFS datastore latency allows proactive alerting when the datastore exceeds the required latency threshold. The esxcli storage core device list command is intended for block storage devices and paths, not NFS datastores. The --verbose NFS option listed here is not the required method for collecting detailed performance metrics in this scenario. VCF Operations Logs is log-focused, not the correct graph source for NFS throughput validation. vSAN Performance Service applies to vSAN performance, not external NFS datastore monitoring. Reference topics: NFS Datastore Monitoring, vCenter Datastore Performance, NFS Host Validation, vCenter Performance Alarms.

An administrator has been presented with the following requirements from an application owner:
* The application is distributed across multiple data centers.
* The application currently uses NFSv4.1 for mounting data volumes.
* The application requires Kerberos encryption.
Drag and drop the three correct options from the Options list on the left and place them into the Required Options on the right to properly configure the storage solution to meet the requirements in any order. (Choose three.)

正解：

Explanation:
The user account used by the application.
The Active Directory used by the application.
The password used by the application.
NFSv4.1 with Kerberos requires identity integration through Active Directory and a valid Kerberos- capable user credential. In vSphere, Kerberos authentication for NFS 4.1 uses Active Directory credentials so ESX can authenticate securely when mounting Kerberos-protected NFS datastores. The required inputs are the Active Directory domain, the user account, and the password associated with that account. The storage guide also states that when several ESX hosts access the same NFS 4.1 datastore, all hosts must use the same Active Directory credentials to ensure consistent access. The Organizational Unit is not the required credential element for datastore mounting. The DNS name of a Kerberos server may be resolved through Active Directory and DNS infrastructure, but it is not one of the required configuration values selected here. A "Kerberos Key Management Server" is not part of the vSphere NFSv4.1 Kerberos datastore configuration model. Therefore, the required options are the application's user account, its Active Directory, and the account password. Reference topics: NFSv4.1 Datastores, Kerberos Authentication, Active Directory Credentials, Kerberos Security for NFS.

An architect is designing a vSAN Original Storage Architecture (OSA) cluster for a VMware Cloud Foundation (VCF) Management Domain. The following details were made available:
* 12 hosts, each host with: 3 x 800 GB NVMe (cache) and 12 x 3.84 TB SAS SSD (capacity).
* Planned configuration: 3 disk groups per host (1 NVMe + 4 SSD each).
* Storage policy: FTT = 2 (RAID-1), Checksum. Deduplication and Compression are Enabled.
* Network: 25 GbE dedicated vSAN network fabric, properly configured for jumbo frames.
After deployment and loading test data to 70% capacity, the operations team reported extended resync times when two hosts are placed into maintenance mode with "Ensure Accessibility" selected and no hardware or network bottlenecks were detected.
How can the administrator explain the observed behavior?

• A.Deduplication and compression cause cache-tier contention during resync.
• B.With 3 disk groups per host, vSAN introduces additional metadata and resync operations under FTT = 2.
• C.NVMe devices in the cache tier limit backend de-staging throughput during resync.
• D."Ensure Accessibility" triggers a full component migration when FTT = 2, regardless of available quorum.
