A vSAN administrator has recently upgraded a vSAN cluster to 7.0 U1 and has enabled Capacity Reserve features to reduce the amount of capacity reserved for transient and rebuild operations.
Which scenario would prevent this feature from operating properly?
A vSAN administrator is investigating vSAN performance related problems but cannot find any vSAN performance statistics on the cluster summary page.
Why is this situation occurring?
vSAN performance statistics are not available on the cluster summary page if the vSAN Performance service is not enabled. This service is responsible for collecting and displaying performance data for vSAN components such as disk groups, virtual machines and virtual disks. Without this service enabled, vSAN performance statistics will not be available on the vSphere Web Client, and the administrator will not be able to monitor the performance of the vSAN cluster.
To enable vSAN Performance service, the vSAN administrator can go to the vSphere Web Client, navigate to the vSAN cluster, click on the Configure tab, and then click on Services. Locate the vSAN Performance service, and click on the Start button.
This is explained in VMware vSAN documentation in the section "Monitoring vSAN Performance" Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-vsan-70-admin-guide/GUID-7E8F6C98-7C0B-4D21-8F1A-F3A3A9F4F4A4.html
A vSAN administrator wants to install a patch on an existing vSAN cluster. The environment runs vSphere 7.0, and the patch contains ESXi 7.0 Update 1c. The vSAN administrator will use vSphere Lifecycle Manager images to add the patch to the proper image and apply it to the vSAN cluster.
Which action should be performed before patching the ESXi hosts in the vSAN cluster?
When viewing the VMware Skyline Health: vSAN Object Health report, the vSAN administrator observes that the link “Repair Objects Immediately” is enabled.
What is the meaning of this message?
A large financial company has an existing vSAN 7.0 U1 cluster containing production virtual machines and the vCenter Server. The cluster needs to be physically moved to another location within the datacenter to allow new racks to be installed, so the platform needs to be powered down.
Which action should the vSAN administrator take to perform this procedure safely?
This option will ensure that the virtual machines remain accessible while the cluster is powered down, while also maintaining data integrity. This option will also ensure that no data is migrated during the power down procedure. Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.virtualsan.doc/GUID-3B072C2A-FBC7-475E-9E4A-2B4D4B8A4F0D.html
A group of virtual machines have the vSAN Default Storage Policy assigned to them. This policy has not been modified from its default settings to date. The vSAN administrator would like to reduce the amount of storage capacity consumed by these virtual machines.
Which action will produce this result?
Object space reservation is a vSAN storage policy attribute that allows the administrator to set a percentage of the provisioned space to be reserved for the virtual machine disk objects. This attribute can be used to reduce the amount of storage capacity consumed by virtual machines. Setting the "Object space reservation" to "50%" will reserve 50% of the total provisioned space for the virtual machines, and free up the remaining 50% for other objects.
It's worth noting that changing object space reservation can result in a component resync, which could cause a performance impact.
This is explained in VMware vSAN documentation in the section "vSAN Storage Policy" Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-vsan-70-admin-guide/GUID-7E8F6C98-7C0B-4D21-8F1A-F3A3A9F4F4A4.html
Which two requirements should the vSAN administrator consider in order to accomplish this goal? (Choose two.)
An administrator is tasked with configuring vSAN Cloud Native Storage.
Which two requirements must be met for a successful configuration? (Choose two.)
A vSAN administrator wants to upgrade a 4-node vSAN Cluster from version 7.0 to the latest version available. The vSAN administrator would like to complete the upgrade as a single task, including firmware and drivers for its hardware.
Which action must the administrator take in order to be able to perform the upgrade?
According to the VMware official documentation, Lifecycle Manager (vLCM) provides an automated and consistent approach to deploying and updating vSAN clusters, including firmware and driver updates. vLCM enables administrators to upgrade a 4-node vSAN cluster from version 7.0 to the latest version available as a single task, using vLCM images within Lifecycle Manager in vCenter. This ensures that the process is done quickly and reliably, without manual intervention or additional steps.
VMware vSphere with Tanzu Release Notes
A large enterprise has a main campus with two 8-Node vSAN 7.0 U1 clusters and 50 remote sites, each containing one 2-Node cluster. An administrator configures a vLCM desired image for lifecycle management, and vLCM had determined that all the clusters are in need of remediation.
How would vLCM enhance the remediation operation in this situation?
vLCM enhances the remediation operation in this situation by allowing the administrator to remediate all remote sites and the main campus concurrently. This allows for faster remediation and reduces the amount of time and effort required by the administrator. The other choices are incorrect, as vLCM can remediate all clusters concurrently, vSphere Update Manager (VUM) cannot be used to remediate the main campus, and vLCM cannot remediate the clusters one-by-one in a parallel manner.
What does enabling vSAN operations reserve help ensure?
Reserves space in case of single host failure. Enabling vSAN operations reserve helps ensure that there is enough capacity available in the vSAN datastore to handle a single host failure. This provides a safeguard against data loss in the event of a host failure, as the vSAN datastore will have the capacity to continue to operate, even if a single host fails. Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.virtualsan.doc/GUID-8D0F3845-6B7C-4477-B8D1-2C1B3C9D0E0C.html
An administrator is responsible for managing an All-Flash vSAN Cluster. The vSAN cluster is configured with two identical vSAN Disk Groups. Neither deduplication nor compression is enabled. The workloads on the vSAN Cluster have consumed 40% of the usable capacity.
Which statement describes the impact to the vSAN cluster if a single cache disk fails within one of the vSAN hosts?
The Cache Disk will be marked as failed, and the Ensure Accessibility option will be required before any components are rebuilt. When a single cache disk fails within one of the vSAN hosts, the Disk Group will be marked as failed and the Ensure Accessibility option will be required before any components are rebuilt. The Ensure Accessibility option will rebuild the components on other cache disks, as long as sufficient capacity is available.
Which two storage policy types are used with the vSAN Data Persistence platform? (Choose two.)
According to VMware's official guide, the vSAN Data Persistence platform uses two storage policy types: Shared Nothing Architecture and vSAN Direct Configuration. Shared Nothing Architecture is a policy type that enables virtual machines to share a common storage pool and enables applications to scale out across multiple nodes. vSAN Direct Configuration is a policy type that allows applications to be deployed directly on the vSAN datastore and enables them to use the underlying vSAN storage features.
About the vSAN Default Storage Policy
VMware vSAN Design Guide | VMware
The DevOps team of an organization wants to deploy their new cloud native application with persistent storage on a dedicated vSAN cluster. The storage administrator is tasked to configure the vSAN cluster and leverage the vSAN Direct feature.
Which two requirements must the administrator meet to complete this task? (Choose two.)
A vSAN cluster has the following configuration:
• 4 hosts with 1 disk group per host
• Each disk group contains 1 cache device and 7 capacity devices
What are two ways to increase the vSAN datastore storage capacity? (Choose two.)
According to the VMware Official Guide, “Adding capacity drives increases the storage capacity of the disk group and the vSAN datastore. Adding a disk group to each host increases the storage capacity of the vSAN datastore.”
A vSAN administrator has been asked to encrypt all traffic for data and metadata across all hosts in a vSAN cluster.
Which action is necessary to achieve this level of encryption?
A vSAN administrator wishes to implement HCI mesh between two clusters that are located in geographically separate data centers.
Which recommendation should the vSAN administrator make for this configuration?
HCI Mesh allows you to connect two or more vSAN clusters together in a stretched cluster configuration, which enables you to share storage resources across the clusters. In order to implement HCI mesh between two clusters that are located in geographically separate data centers, the vSAN administrator should ensure that both Layer 2 and Layer 3 communications are supported between the two data centers. This will allow the vSAN clusters to communicate with each other over both the data and management networks.
This is explained in VMware vSAN documentation in the section "HCI Mesh" Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-vsan-70-admin-guide/GUID-7E8F6C98-7C0B-4D21-8F1A-F3A3A9F4F4A4.html
What is the purpose of host rebuild reserve in vSAN?
A vSAN administrator was presented with 30 additional vSAN ReadyNodes to add to an existing vSAN cluster. There is only one administrator to complete this task.
What is the fastest approach?
