Question1: During yesterday's business hours, a cache drive failed on one of the vSAN OSA nodes. The administrator reached out to the manufacturer and received a replacement drive the following day. When the drive failed, vSAN started a resync to ensure the health of the data, and all objects are showing a healthy and compliant state. The vSAN administrator needs to replace the failed cache drive.
Which set of steps should the vSAN administrator take?

Question2: Which vSAN maintenance mode option should be used to avoid storage policy non-compliance?

Question3: An existing vSAN OSA cluster has this specification:
Four ESXi hosts with all flash configuration
Each with two disk groups
Each disk group with one cache device and four capacity devices
There are five more device slots available per host
The CTO would like to provision new applications, and these will need more capacity and performance.
Which two methods should be used by the vSAN administrator to meet this goal with the least amount of impact? (Choose two.)

Question4: An 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.)

Question5: The Resyncing Objects view in the vCenter UI reports that some objects are currently resyncing.
Which two actions would cause this situation? (Choose two.)

Question6: An administrator has 24 physical servers that need to be configured with vSAN. The administrator needs to ensure that a single rack failure is not going to affect the data availability. The number of racks used should be minimized.
What has to be done and configured to achieve this goal?

Question7: A site administrator wishes to implement HCI mesh between two clusters on vSAN that are located in geographically separate sites and which are administered within a single datacenter.
Which two requirements should the vSAN administrator consider to accomplish this goal? (Choose two.)

Question8: A vSAN administrator notices that the VMware Skyline Health: Network Latency Check reports indicate that three hosts are noncompliant.
Which action should the vSAN administrator take?

Question9: The DevOps team of an organization wants to deploy 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.)

Question10: An architect is designing a vSAN stretched cluster and needs to ensure that data remains on a given site in case of a network partition between the sites.
Which configuration would do this?

Question11: A vSAN administrator has a vSAN cluster that is using vSphere Lifecycle Manager (vLCM) to manage hypervisor, server drivers, and firmware. All hosts in the cluster are compliant according to the vLCM image.
A 10GB NIC on the servers is experiencing issues, and the vSAN administrator determines a new network driver will resolve the problem. Unfortunately, the required NIC driver is a newer version compared to the driver provided by the most recent Vendor Add-on.
Which action should the vSAN administrator take to ensure the latest network driver is installed on the NIC before remediation?

Question12: A vSAN administrator has a cluster configured with a Storage Pool that was moved to a new physical DC.
Upon checking on the vSAN cluster health status, one of the ESXi hosts has two storage devices in a degraded state and must be replaced.
What must the vSAN administrator do to restore the health of the vSAN cluster with minimum risk?

Question13: A vSAN administrator encounters a non-compliant virtual machine and the compliance status of some of its objects is noncompliant. vSAN is able to locate a full replica of 55% of the votes for the noncompliant objects.
What will vSAN do with the virtual machine?

Question14: A vSAN administrator needs to enable vSAN ESA.
Which two requirements need to be met? (Choose two.)

Question15: An administrator is tasked to create a Kerberos secured NFS v4.1 file share.
Which information is minimally required during the configuration of the File Service?

Question16: A vSAN administrator has an existing cluster where each ESXi host has the following:
Disk group #1 with one cache device and three capacity devices.
Disk group #2 with one cache device and two capacity devices.
What must the vSAN administrator do to expand disk group #2 to have three capacity devices?

Question17: 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?

Question18: Which VMware solution requires vSAN usage?

Question19: An organization plans to implement a new vSAN 8.0 cluster to take advantage of the new features around improved I/O flow, better resiliency, and more efficient disk usage. The vSAN ReadyNodes available for the cluster consist of eight NVMe disks.
How should the organization configure the disk layout?

Question20: An administrator has been tasked with upgrading existing vSAN OSA cluster hosts with a SSD cache device per host to a NVMe device (hot plug).
Which fact should guide the administrator's action?

Question21: Refer to the exhibit.
An administrator uses SSH to log into a vSAN ESA host and runs theesxcli vsan debug object overview command.

The administrator notices the Healthy Components column, the last column, is reporting some components are not in a fully healthy state.
What could cause this behavior?

Question22: Which two considerations should an architect assess when designing a HCI Mesh solution with VMware vSAN and VMware vSphere High Availability (HA)? (Choose two.)

Question23: How often does the Skyline Health interval validate online if there are new Health Checks available for vSAN?

Question24: What are two characteristics of the vSAN Data-At-Rest Encryption (DARE)? (Choose two.)

Question25: A vSAN administrator needs to build a vSAN ESA cluster with RAID-5/FTT 1 adaptive storage policy.
What is the absolute minimum number of hosts that need to be part of that vSAN ESA cluster?

Question26: A vSAN administrator is noticing that the objects resynchronizing in the cluster are taking longer than expected and wants to view the resynchronizing metrics.
Which performance category should the vSAN administrator open?

Question27: An application refactor requires significant storage that is being added for logs stored on a VM vDISK. The application VMs run on a dedicated vSAN enabled vSphere Cluster with custom CPUs and RAM, and therefore, cannot vMotion to another vSAN enabled cluster.
The administrator needs a vSAN feature that can be used to allocate additional storage from another vSAN enabled vSphere cluster to this vSAN enabled Cluster.
Which vSAN feature should be used for this purpose?

Question28: After a planned power outage, an administrator decided to restart the vSAN cluster manually.
What is the correct sequence of steps for the administrator to follow after powering on the ESXi hosts?

Question29: A customer has deployed a new vSAN cluster with the following configuration:
5 x vSAN ReadyNodes
All Flash
12 TB Raw Storage
vSAN 8 is deployed with ESA.
New VMs are configured with a RAID-5 VM policy.
Which statement is accurate?

Question30: In which type of environment is vSAN storage used as a mandatory, primary storage?

What is the fastest approach?

Question32: A customer wishes to host a new range of applications with high-performance needs, specifically, low latency.
