A vSAN administrator needs to find the metrics for objects containing data served up by the vSAN iSCSI service.
On which level should the vSAN administrator look?
- A. Cluster
- B. Virtual Machine
- C. vSAN iSCSI Object
- D. vCenter Server
Answer: A
Explanation:
The vSAN administrator should look at the cluster level to find the metrics for objects containing data served up by the vSAN iSCSI service [1]. According to VMware's Official Guide, "vSAN performance service provides storage-centric visibility to a cluster-wide set of performance metrics and statistics that are collected on a regular basis". This means that the vSAN administrator should look at the cluster level to view the metrics and statistics for the vSAN iSCSI service [1].

NEW QUESTION # 29
An administrator is preparing maintenance on a host in a vSAN cluster, and the maintenance is expected to take less than one hour. The administrator is considering using the "Full Data Migration" but understands that this can be time consuming and also has additional capacity and performance considerations.
Which action would alleviate these concerns?
- A. Take an outage window when users are less likely to be working.
- B. Use maintenance mode with "No Data Migration".
- C. Use maintenance mode with "Ensure Accessibility".
- D. Use maintenance mode with "Ensure Accessibly", and increase the vSAN object repair timer to more than one hour.
Answer: B
Explanation:
According to VMware's documentation, the "No Data Migration" option for maintenance mode should be used when the expected maintenance time is less than one hour. This option will allow the administrator to complete their maintenance without having to wait for a full data migration, which can be time consuming and also has additional capacity and performance considerations. It is important to note that this option will not guarantee the same level of availability as the other options, so it should only be used when the expected maintenance time is less than one hour.

NEW QUESTION # 32
vSAN requires that the virtual machines deployed on the vSAN datastores are assigned at least one storage policy, but the administrator did not explicitly assign a storage policy when provisioning the new VM.
What is the result of this situation?
- A. The vSphere Web Client will choose the last vSAN Storage Policy used.
- B. No data protection will be applied to the VM objects.
- C. The VM provisioning will fail.
- D. The VM objects will be protected based on the vSAN Default Storage Policy configurations.
Answer: D
Explanation:
When a virtual machine is deployed on a vSAN datastore, it must be assigned at least one storage policy. If the administrator did not explicitly assign a storage policy when provisioning the new VM, vSAN will apply the vSAN Default Storage Policy to the virtual machine. The vSAN Default Storage Policy is a pre-configured storage policy that is automatically applied to virtual machines when no other storage policy is assigned.
According to VMware's official guide, "If a storage policy is not explicitly assigned to a virtual machine when it is provisioned, the virtual machine objects will be protected based on the vSAN Default Storage Policy configurations." This means that the vSAN Default Storage Policy will apply to the VM objects even if the administrator did not explicitly assign a storage policy when provisioning the new VM.
NEW QUESTION # 33
A vSAN administrator has been provided hardware to create the vSAN infrastructure. AH six SSD devices per host are on the VMware HCL. The administrator wants to use the disk group configuration that would maximize the amount of vSAN cache available and help provide better storage performance for the new development workloads.
Which disk group configuration should be used?
- A. A single disk group with 6 disks in the configuration
- B. 2 disk groups with 3 disks in each disk group configuration
- C. 6 disk groups with 1 disk in each disk group configuration
- D. 3 disk groups with 2 disks in each disk group configuration
Answer: D
Explanation:
According to the VMware official documentation, this is the recommended disk group configuration for maximizing the amount of vSAN cache available and providing better storage performance for development workloads. This configuration allows for more capacity and flash devices to be used, increasing the amount of available cache and providing more storage options. Additionally, this configuration allows for more flexibility in the sizing of the capacity tier, allowing the administrator to adjust the size of the capacity tier to best suit the needs of the workloads.
NEW QUESTION # 34
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. Put the VMs in the correct VM group.
- B. Create VM/Host groups for the two sites.
- C. Create a storage policy that includes site affinity rules and apply to VMs.
- D. Put the VMs in a vSphere DRS group.
- E. Create a single VM/Host group across both sites.
Answer: B,C
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.
NEW QUESTION # 35
Which state is NOT a compliance status of a VM Storage Policy?
- A. Not Applicable
- B. Compliant
- C. Stale
- D. Noncompliant
Answer: C
NEW QUESTION # 36
A vSAN storage policy with the 'Failures lo Tolerate" rule set to "2 failures - RA1D-1 {Mirroring)" is assigned to multiple virtual machines.
The vSAN administrator is considering assigning a new vSAN storage policy with the "Failures to Tolerate' rule set lo '2 failures - RAID-6* (Erasure Coding)" to the virtual machines.
How will the capacity of the vSAN datastore be affected if this action is taken?
- A. Additional capacity is permanently consumed by the erasure coded components.
- B. Free capacity is permanently reduced after the Object Repair Timer expires.
- C. Additional free capacity will be available for immediate use.
- D. Used capacity will increase temporarily while the erasure coded components are built.
Answer: D
Explanation:
Used capacity will increase temporarily while the erasure coded components are built. When a vSAN storage policy with 'Failures to Tolerate' set to '2 failures - RAID-6 (Erasure Coding)' is assigned to multiple virtual machines, the components of the objects stored on the vSAN datastore will be rebuilt in an erasure coding format, which requires additional capacity. This additional capacity will be used temporarily while the erasure coded components are built, and will be reclaimed once the process is complete.

NEW QUESTION # 37
A vSAN administrator observes that the VMware Skyline Health: Disk Format Version reports a format version that is lower than the expected version.
What does this status mean?
- A. A vSAN on-disk format upgrade is recommended.
- B. Deduplication and compression must be disabled for the vSAN datastore.
- C. The vSAN administrator must enable encryption for the vSAN datastore.
- D. The vSAN administrator must perform an immediate upgrade of the on-disk format.
Answer: D
Explanation:
The vSAN administrator must perform an immediate upgrade of the on-disk format. This status indicates that the vSAN on-disk format version is lower than the expected version. This could be caused by an incompatible version of the vSAN software or may be due to a failed upgrade attempt. In order to address this issue, the vSAN administrator must perform an immediate upgrade of the on-disk format.

NEW QUESTION # 40
An administrator has deployed a new vSAN cluster that contains eight hosts and needs to configure a storage policy for the currently deployed database virtual machines. The requirements state that if two hosts in the vSAN cluster fail, all virtual machines are unaffected.
Which RAID configuration must the administrator use in this storage policy to achieve the best performance for the database virtual machines?
- A. RAID-1
- B. RAID-6
- C. RAID-0
- D. RAID-5
Answer: B
Explanation:
The RAID configuration that the administrator must use in this storage policy to achieve the best performance for the database virtual machines is RAID-6.
RAID-6 is an effective configuration for a vSAN cluster with eight hosts as it allows for two hosts to fail and still maintain protection of the data. RAID-6 is a data striping configuration with two parity bits stored across multiple disks, which improves read performance while also providing fault tolerance.
For more information, see the official VMware guide on vSAN Storage Policies: https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.vsan.doc/GUID-DAC07A3E-A077-4A93-A9D0-9CBB2F4F4B4D.html
NEW QUESTION # 41
A vSAN administrator has reported a security vulnerability to the security officer of the organization. Currently, the vSAN cluster runs on vSAN 7.0. The administrator suggests patching the vSAN cluster and gets approval from the security officer to apply the latest patch for vSAN.
The administrator uses vSphere Lifecycle Manager to apply the patch to the current image. The organization requirements state that patches should be installed as fast as possible on the hosts.
Which configuration should the administrator apply to complete this installation?
- A. Enable the quick boot feature in the host remediation settings for the baselines.
- B. Disable HA admission control in the host remediation settings for the baselines.
- C. Disable the hardware compatibility check in the host remediation settings for the images.
- D. Enable the quick boot setting in the host remediation settings for the images.
Answer: D
Explanation:
The correct configuration that the administrator should apply to complete this installation is C. According to the VMware vSphere Lifecycle Manager Administration Guide [1], the quick boot setting in the host remediation settings for the images should be enabled in order to quickly apply the patch to the hosts. Quick boot is a feature that allows the host to restart with minimal downtime, and it allows the patch to be applied faster than if the host had to be restarted from the beginning. Disabling the hardware compatibility check and disabling HA admission control are not necessary and will not speed up the patching process.
