Question 2

A customer is planning to deploy a vSAN cluster to host their in-house distributed ERP system. The hardware specifications for their server nodes include:

* 2 x Intel Xeon CPU E5-2697 v3 @ 2.60GHz

* 1TB memory

Which boot device is supported for the vSAN ESXi nodes for this customer?

AA 16GB single-level cell (SLC) SATADOM device must be used.

BA 4GB USB or SD device must be used.

CA 16GB multiple-level cell (MLC) SATADOM device must be used.

DESXi Hosts must boot from a PMEM device.

Answer : A

If the memory of the ESXi host has 512 GB of memory or less, you can boot the host from a USB, SD, or SATADOM device. If the memory of the ESXi host has more than 512 GB, consider the following guidelines. * You can boot the host from a SATADOM or disk device with a size of at least 16 GB. When you use a SATADOM device, use a single-level cell (SLC) device. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-planning.doc/GUID-B09CE19D-A3F6-408C-AE69-35F65CBE66E1.html

Question 3

Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to at least double the usable capacity in their all-flash vSAN cluster.

The vSAN cluster is deployed into a co-located datacenter that is owned by a third-party hosting company. The hosting company charges a fixed monthly cost for rack space and power consumption. The service owner has been given a limited budget for additional hardware purchases, but not for on-going co-location costs.

The current vSAN cluster has the following configuration:

* 10 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM

* 1 Disk Group per vSAN node

- 1 x 400 GB

- 4 x 1.8 TB

* De-duplication and Compression is enabled.

* vSAN Capacity is currently:

- Total: 72 TB

- Usable: ~40 TB (FTT1/RAID1) and ~60 TB (FTT1/RAID5).

As a result of any action taken, the service owner would like to ensure that overall availability of the vSAN cluster is increased.

Which two recommendations meet the requirement to increase capacity while maintaining service availability? (Choose two.)

AInstall an additional 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.

BUpdate the existing Disk Group, and claim the newly installed drives for each node.

CCreate a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.

DInstall an additional 3 x 1.8 TB SSDs per vSAN node.

EReplace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.

Answer : A, C

Option A meets the requirement by adding additional SSDs to each vSAN node, which will increase the total capacity of the vSAN cluster. By installing the same type of SSDs that are currently being used, this option will also maintain the same level of service availability.

Option C meets the requirement by creating a new disk group and adding the newly installed SSDs to it. By creating a new disk group, it will allow you to use the new SSDs as a separate cache and capacity tier, which will improve the cluster's performance and increase the usable capacity.

Question 4

In a vSAN stretched cluster, which value must be set in the vSAN policy if there is no requirement for data mirroring across sites?

ASFTT = 0

BSFTT = 1

CPFTT = 1

DPFTT = 0

Answer : D

PFTT can be seen as ''site failures'', and you can always only tolerate 1 at most. SFTT can be seen as host failures, and you can define this between 0 and 3 https://www.yellow-bricks.com/2018/03/19/vsan-stretched-cluster-pftt-and-sftt-what-happens-when-a-full-site-fails-and-multiple-hosts-fail/

Question 5

Which statement accurately describes the result when proper VM Storage Policy Affinity Rules on a stretched vSAN cluster are set?

AWhen a site is disconnected, the VM will lose access to its VMDK.

BWhen a site is disconnected, the VM will continue to have access to its VMDK.

CBandwidth is unnecessarily sent across the inter-site link.

DProper policies result in higher inter-site bandwidth utilization.

Answer : B

Setting proper VM/Host Group Rules and VM Storage Policy Affinity Rules are beneficial for several reasons Bandwidth is not unnecessarily sent across the inter-site link Lower inter-site bandwidth utilization In the situation where the alternate site is disconnected, the VM will continue to have access to its vmdk. from https://core.vmware.com/resource/vsan-stretched-cluster-guide#sec7341-sub5

Question 6

A customer has upgraded to vSAN 7, but there is still an existing legacy host which must be removed from the vSAN cluster.

Which three steps must an administrator take to successfully remove this host from the vSAN cluster? (Choose three.)

APlace the host in maintenance mode with Ensure Accessibility

BDisconnect from vCenter Server

CPlace the host in maintenance mode with Full Data migration

DPlace the host in maintenance mode with no data migration

ERemove from vSAN cluster

FDelete the disk group(s) on the legacy host

Answer : C, E, F

Question 7

A cache disk failure marked a vSAN disk group as failed, and the data is being rebuilt on other disk groups.

Which action should the vSAN administrator take to reduce the negative impact on the VMs?

AEnabling Resync Throttling

BEnabling Maintenance mode with no data evacuation

CEnabling automatic rebalance

DSetting the vSAN policy's IOPS limit for object value to 0 (unlimited)
