質問 # 79
An administrator has deployed a dedicated VMware vSAN 7.0 U1 cluster that will be used to provide developers with access to an environment that is running VMware with Tanzu workloads only.
Which vSAN feature should be configured for vSAN Data Persistence platform (vDPp)?
- A. vSAN File Services
- B. vSAN Cloud Native Storage
- C. vSAN Direct
- D. vSAN with Shared Nothing Architecture (SNA)
正解：D
解説：
According to the VMware official documentation, vSAN with SNA is the recommended configuration for the vSAN Data Persistence platform (vDPp). This configuration provides support for high availability [1], scalability, and enterprise-grade security. With SNA, the entire vSAN cluster is connected over a single high-speed network, and each node has direct access to the shared storage. This ensures that workloads are balanced across the cluster, which in turn improves performance and reliability. Additionally, SNA ensures that storage is accessible to all nodes in the cluster, eliminating the need for any centralized storage controllers.

質問 # 84
A vSAN Administrator has a cluster of six vSAN nodes. The vSAN datastore was 55% utilized, and due to a power outage, one node was lost. The vSAN administrator needs to resolve the storage policy compliance for the virtual machines on RAID-5.
Which action, if any, needs to be taken to meet this goal?
- A. Change the RAID-5 FTT from 2 to 1.
- B. Trigger vSAN object repair from ESXCLI.
- C. The one failed node must be restored.
- D. No action is needed since vSAN automatically rebuilds the objects.
正解：A
解説：
When a node is lost in a vSAN cluster, the vSAN will automatically begin to rebuild objects in order to meet the storage policy compliance. However, if the storage policy includes RAID-5 with a "Failures to Tolerate" (FTT) value of 2, it won't be possible to rebuild the objects and meet the storage policy compliance with only 5 nodes. In this case, the vSAN administrator needs to change the RAID-5 FTT from 2 to 1, this will allow the vSAN to rebuild the objects and meet the storage policy compliance with only 5 nodes. With RAID-5, the FTT value of 1 is the minimum value supported by vSAN.
This is explained in VMware vSAN documentation in the section "RAID-5 and RAID-6 Erasure Coding" Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-vsan-70-config-guide/GUID-1A5F48D5-F8C9-4C7E-9D9B-F9D4B4E4A4F4.html Changing the RAID-5 FTT from 2 to 1 will ensure that the virtual machines on the vSAN datastore are in compliance with the storage policy. This is because, with a RAID-5 FTT of 2, the cluster needs at least 6 nodes to meet the redundancy requirements. With a single node lost, the cluster cannot meet this requirement and so the virtual machines on the datastore will be out of compliance. By changing the FTT from 2 to 1, the cluster will be able to meet the redundancy requirements with only the remaining 5 nodes, ensuring compliance with the storage policy.

- B. Roll back the vLCM configuration to the latest compliant image.
- C. Stage the upgrade images.
- D. Place all hosts in maintenance mode.
正解：B
解説：
Roll back the vLCM configuration to the latest compliant image. After saving the configuration, all hosts in the cluster are out of compliance, so the next step is to roll back the vLCM configuration to the latest compliant image. This can be done by selecting the "Roll Back" option from the vLCM image selection menu. Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.upgrade.doc/GUID-B2F7B3A3-BD7F-4A4F-A77C-90F4B7EAC54F.html
質問 # 88
A vSAN administrator has been asked to increase the usable storage capacity of an existing vSAN cluster to deploy some new virtual machines containing a large amount of dat a. The details are as follows:
* Each ESXi host in the vSAN cluster is configured with two disk groups.
* Each disk group contains three capacity devices and one cache device.
* Deduplication and compression are not enabled.
* Only the default VM storage policy is in use and had not been changed.
* Add capacity without re-creating disk groups.
