NEW QUESTION 28
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. Trigger vSAN object repair from ESXCLI.
- B. The one failed node must be restored.
- C. No action is needed since vSAN automatically rebuilds the objects.
- D. Change the RAID-5 FTT from 2 to 1.
Answer: D
Explanation:
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.

NEW QUESTION 36
The administrator has successfully deployed a vSAN Stretched Cluster and needs to ensure that any virtual machines that are created are placed in the appropriate site.
Which two steps are needed to complete this task? (Choose two.)
- A. Create a single VM/Host group across both sites.
- B. Create a storage policy that includes site affinity rules and apply to VMs.
- C. Put the VMs in the correct VM group.
- D. Create VM/Host groups for the two sites.
- E. Put the VMs in a vSphere DRS group.
Answer: B,D
Explanation:
When deploying a vSAN Stretched Cluster, site affinity rules can be used to ensure that virtual machines are placed in the appropriate site. To do this, the following steps are required:
Create a storage policy that includes site affinity rules: This can be done by creating a new storage policy and configuring the "site placement" rules for each site. For example, you can configure a rule that all virtual machines must reside in site A.
Apply the storage policy to VMs: Once the storage policy is created, it needs to be applied to the virtual machines that need to be placed in the appropriate site.
Additionally, to ensure that virtual machines are placed in the correct site, it is also necessary to create VM/Host groups for the two sites. These groups can be used to separate the virtual machines and hosts in the different sites, and the storage policy can be applied to the appropriate group.

A vSAN administrator is deploying a four node vSAN cluster to a new work location. To help with configuration and consistency, the vSAN administrator plans to use Ouickstart Which two prerequisites must be met prior to taking this action? (Choose two.)
- A. Hosts are running 6.0 U2 or later.
- B. DRS and HA have been enabled.
- C. Hosts do not have existing vSAN or network configurations.
- D. vDS must be created tor vSAN and management traffic.
- E. vCenter is running on one of the four nodes.
Answer: A,C
Explanation:
Quickstart is a configuration tool that guides vSAN administrators through the process of creating a vSAN cluster from scratch. It is available in vCenter Server 6.0 U2 and later versions. Therefore, before using Quickstart, it is important to ensure that all hosts are running 6.0 U2 or later. The hosts should not have any existing vSAN or network configurations, to avoid any conflicts with the new vSAN cluster being deployed. This is explained in VMware vSAN 6.7 documentation in the section "Creating a vSAN Cluster using the Quickstart Configuration" Reference: https://docs.vmware.com/en/VMware-vSphere/6.7/vsphere-vsan-67-admin-guide/GUID-7A6C9F9C-1F74-4E44-8848-B1A2FBC6F2F6.html

What happens to a disk group during cache disk removal?
- A. It changes the on-disk format.
- B. It uses one of the capacity devices as cache.
- C. It goes offline.
- D. It uses the spare cache disk.
Answer: C
Explanation:
When a cache disk is removed from a disk group in a vSAN cluster, the disk group goes offline. This means that the disk group is not available for use and the data stored on it is not accessible. This is done to prevent data corruption and to ensure the integrity of the data stored on the vSAN.
