A storage architect has been called into a meeting with the accounting team who is trying to determine why
20% of their raw capacity is not available for consumption. Their vSAN cluster was created with the following characteristics:
* 2 x 2 TB NVMe disks in 6 hosts in their vSAN cluster.
* FTT=1, RAID-1 for the default policy.
* Host Rebuild Reserve not activated for this cluster.
Which two items should the Architect say accounts for most of the unusable capacity? (Choose two.)

During maintenance on hosts in a four-node vSAN cluster, a host is placed in maintenance mode with the
"Ensure Accessibility" option.
All VMs are running with the Default Storage Policy (RAID-1, FTT=1) which has not been modified from the default settings.
While one of the hosts in the cluster is down for firmware upgrade, a second host in the cluster loses network connectivity.
How will the cluster be affected?

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.)
* The application is distributed across multiple data centers.
* The application currently uses NFSv4.1 for mounting data volumes.
* The application requires Kerberos encryption.

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.

A clustered legacy application is scheduled for decommissioning at the end of the month. While in use, it stored application and quorum data on a pair of vSAN iSCSI Target LUNs.
After the vSAN iSCSI Target Service is disabled, what will happen to the existing targets and LUNs?

An administrator has been tasked with suggesting storage models for a new VMware Cloud Foundation (VCF) Private Cloud. The following information has been provided:
* All existing implementations of VMware vSphere use the existing third-party block-based storage solution.
* The block-based storage solution only has sufficient scale, capacity and IOPS to cater for the new workload storage requirements.
* There is a dedicated and highly resilient storage area network connecting hosts to the provided block-based storage.
* There are 5 existing hosts with enough CPU and RAM resources and resilient Host Bus Adapters (HBAs) to cater for the new workload resource requirements only.
* There is sufficient budget to purchase some hardware, however the solution must re-use the existing hardware where possible.
The administrator suggests the following high-level solution:
* Single VCF Instance with a single Workload Domain.
* Deploy 4 new servers to create a Management Domain.
* Repurpose the 5 existing servers to create a single cluster in the Workload Domain.
Which two storage models should the administrator recommend? (Choose two.)
