An administrator just built a new workload domain including a vSAN ESA cluster. The architecture design included the use of memory tiering and a specific smaller NVMe device has been installed in each ESX host for this purpose.
When looking in the vSphere UI, the administrator notices that the device intended to be used for memory tiering has been claimed by vSAN.
What action should be taken on each host to achieve the desired configuration?

• A.  Remove the device from vSAN performing a full data migration and configure that device for memory tiering.
• B.  Boot the host one time with the tiering device removed, then shut down again. Reconnect the tiering device and boot the host.
• C.  Change vSAN disk claiming from automatic to manual and sequentially reboot each ESX host of the cluster after putting them in maintenance mode using the "Ensure Accessibility" option.
• D.  After turning on the LED on the memory tiering device, hot remove it from the ESX host; vSAN will rebuild the required objects.

The security team has notified the VMware Cloud Foundation (VCF) Storage Administrator of a new security vulnerability that must be patched immediately. The vSAN Cluster uses vSphere Lifecycle Manager images.
After updating the image with the patch, what method should the administrator use to apply this patch with the least amount of disruption to the cluster?

• A.  Disable the Quick Boot feature in the host remediation settings for the images.
• B.  Disable HA admission control in the host remediation settings for the baselines.
• C.  Enable the suspend to memory feature in the host remediation settings for the baselines.
• D.  Enable the Quick Boot setting in the host remediation settings for the images.

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.)

Correct Answer:

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 agency is designing its secure private cloud on VMware Cloud Foundation with the following requirements:
* Strict data segregation between the management and workload domains.
* Company policy prevents using vSAN as a storage solution.
* Data encryption at rest is mandatory for both the management and workload domains.
* Data encryption in transit is mandatory for the workload domains.
* Data-at-rest encryption must be performed by the storage array and not rely on VMware native or vSAN- specific mechanisms.
* Allow for automated VM placement, operational integrity with VCF Operations, and assurance that file- based workloads scale efficiently.
Which storage architecture fulfills these technical and regulatory requirements?

• A.  Configure dedicated VMFS datastores on separate Fibre Channel arrays for management and workloads, with array-based encryption enabled and SPBM storage policies assigned. Use NFS v4.1 shares with Kerberos-based encryption for in-transit data for file workloads in the workload domain, restricting cross-domain datastore access.
• B.  Create a unified NAS platform offering both NFS and SMB exports shared across management and workload domains, then enable application-level encryption for sensitive workloads and restrict access via firewall rules.
• C.  Deploy metro clusters backed by Self-Encrypting Disk (SED) using iSCSI for both domains and configure encrypted VLANs for data-in-transit between VCF Operations and hosts.
• D.  Enable VMware VM-level encryption using vSphere Native Key Provider (NKP) on local VMFS disks for all environments, implementing manual file workload allocation through generic SMB shares.

A cache drive failed on one of the vSAN OSA nodes in the cluster.
When the drive failed, vSAN started a resync to ensure the health of the data, and all objects are showing a healthy and compliant state.
The vSAN administrator needs to replace the failed cache drive.
Which set of steps should the vSAN administrator take?

• A.  Physically replace the failed cache device, and vSAN will automatically allocate the storage.
• B.  Remove the existing vSAN disk group, and physically replace the device. Then, check to verify that the ESX host automatically detects the new device. Afterwards, manually recreate the Disk Group.
• C.  Place the disk group into maintenance mode, and select Full Data Migration. Then, physically replace the failed cache device. Afterwards, vSAN will rebuild the disk group automatically.
• D.  Physically replace the failed cache device, and vSAN will automatically create a new disk group. Then, remove the disk group with the failed device.
