質問 1：
A vSAN ESA cluster experienced a host NVMe failure, causing several objects to become non-compliant.
Select the steps vSAN ESA follows to detect, evaluate and repair the non-compliant objects.
Drag and drop the four correct options from the Options list on the left and place them into the Required Options on the right in any order. (Choose four.)
正解：
Explanation:
ESA evaluates available capacity and fault domains to satisfy policy compliance.
vSAN detects the failure and marks affected objects as non-compliant.
Resync completes and objects transition to Compliant status.
New components are instantiated on eligible capacity devices, and resync begins.
A failed NVMe device in a vSAN ESA cluster is handled as a storage pool device failure. vSAN first detects the failure and marks affected objects as non-compliant when their assigned storage policy requirements are no longer satisfied. ESA then evaluates available capacity and fault domains to determine whether replacement components can be placed in a way that restores compliance. If sufficient placement resources exist, vSAN creates new components on eligible capacity devices and begins resynchronization. After the resync completes, the affected objects transition back to Compliant status. The Repair Delay Timer is primarily associated with absent components, such as a host or device that may return, and is not the required step for a permanent NVMe failure. The administrator does not have to manually trigger Repair Objects Immediately for the normal automatic repair process. A full cluster rebalance is separate from repair and is not performed before rebuilding missing or degraded components.

質問 3：
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. There is congestion in one or more disk groups.
B. The Virtual Machines are using PVSCSI controllers.
C. Jumbo frames are enabled on the VMkernel adapters.
D. Erasure Coding is disabled in the storage policy.

質問 4：
An administrator is tasked with deploying a vSAN ESA Stretched Cluster for a VMware Cloud Foundation (VCF) workload domain. The stretched cluster must meet the following requirements:
* Ensure the cluster supports a storage policy with a secondary level of resilience of FTT=2 using RAID-6 erasure coding.
* Allow vSAN to regain its prescribed level of resilience in the event of a sustained host outage.
What is the minimum number of hosts required in each availability zone?
A. 14
B. 6
C. 12
D. 7

質問 5：
After a planned power outage, an administrator decided to restart the vSAN cluster manually.
Drag and drop the three correct options from the Options list on the left and place them into the Required Options on the right in any order. (Choose three.)
正解：
Explanation:
Run the Python reboot helper script only on one ESXi host to recover the cluster.
Enable cluster member updates from vCenter Server on all ESXi hosts.
Exit all hosts from maintenance mode.
During a manual vSAN cluster restart after a planned outage, the hosts must first be brought back and exited from maintenance mode so the cluster can begin recovery. The vSAN reboot helper recovery script must then be run on only one ESXi host. Running the script on multiple hosts can create race conditions and unexpected cluster state. After the recovery script completes, cluster member updates from vCenter Server must be enabled on all ESXi hosts so that normal membership updates resume across the cluster. Enabling updates on only one host is incomplete because all hosts must return to normal cluster-member update behavior. Running the Python reboot helper script on all ESXi hosts is explicitly incorrect because the recovery operation must be initiated from a single host only. Disabling cluster member updates is a shutdown-side activity, not the required restart-side recovery action in this question. Reference topics: Manual vSAN Cluster Restart, Reboot Helper Script, Maintenance Mode Exit, Cluster Member Updates.
質問 6：
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.)
A. Fibre Channel should be the principal storage solution for the VCF Workload Domain.
B. VMware vSAN should be the principal storage solution for the VCF Workload Domain.
C. iSCSI should be the principal storage solution for the VCF Management Domain.
D. VMware vSAN should be the principal storage solution for the VCF Management Domain.
E. iSCSI should be the supplemental storage solution for the VCF Workload Domain.
