A vSAN architect is using the vSAN Sizer to build an All-Flash vSAN cluster for an accounting company. The architect is trying to determine why 12 TBs are set aside for system overhead and is reviewing the items that are include in the overhead capacity.

Which two items are included? (Choose two.)
A . VM swap overhead
B. Encryption overhead
C. Disk Format overhead
D. Host upgrade overhead
E. File System overhead

View Answer

Answer: C,D

Explanation:

According to the VMware vSAN Sizer guide [1], system overhead includes disk format overhead and host upgrade overhead. Disk format overhead is needed to accommodate the additional metadata associated with the vSAN disk format, and host upgrade overhead is needed to support any future host upgrades.

Which VM file type resides in the VM home namespace object on a vSAN datastore?
A . vmem
B vmx
B. vswp
C. vmsn

View Answer

Answer: B

Explanation:

Virtual machines deployed on Virtual SAN are made up of a set of objects. For example, a VMDK is an object, a snapshot is an object, VM swap space is an object, and the VM home namespace (where the .vmx file, log files, etc. are stored) is also an object. Each of these objects is comprised of a set of components, determined by capabilities placed in the VM Storage Policy.

Which two storage policy changes result in a component resync? (Choose two.)
A . Changing object space reservation to 100
B. Changing the failure tolerance method
C. Disabling object checksum (from checksum enabled)
D. Adding an IOPS Limit rule to a storage policy
E. Enabling object checksum (from checksum disabled)

View Answer

Answer: B,E

Explanation:

he correct answers are B and E. Changing the failure tolerance method and enabling object checksum (from checksum disabled) both result in a component resync. When the failure tolerance method is changed, the components of the objects stored on the vSAN datastore need to be rebuilt in the new format, which requires a component resync. Similarly, when object checksum is enabled, the components of the objects stored on the vSAN datastore need to be rebuilt in order to enable checksum.

What should be used to verify object resynchronization progress and impact after a global policy change?
A . HCI Bench
B. vCenter HTML5 client
C. vRealize Log Insight
D. vRealize Network Insight

View Answer

Answer: C

Explanation:

To verify object resynchronization progress and impact after a global policy change, you can use vRealize Log Insight (C). According to the VMware Official Guide, “The vRealize Log Insight dashboard can be used to verify object resynchronization progress and impact after a global policy change.”

A VMware vSAN administrator is configuring advanced monitoring with VMware vRealize Operations Manager and has the following requirement:

• Ability to receive analytical information from the hard drive to determine a possible future failure of the hard drive.

What should be enabled for data collection when configuring the vSAN Adapter Instance?
A . IOPS (Input/Output Operations Per Second)
B. DST (Disk Self-Test)
C. SMART (Self-Monitoring, Analysis and Reporting Technology)
D. SSP (Storage Service Provider)

View Answer

Answer: C

Explanation:

Self-Monitoring, Analysis and Reporting Technology (SMART) is an industry-standard technology that allows hard drives to report on their own health, including the ability to predict possible future failures. When configuring the vSAN Adapter Instance in vRealize Operations Manager, the administrator should enable SMART data collection to be able to receive analytical information from the hard drives and monitor their health.

By enabling SMART data collection, the administrator can use the data to identify potential issues with hard drives, monitor their health status, and take appropriate actions to prevent data loss.

This is explained in VMware vSAN documentation in the section "Monitoring vSAN Disk Health with vRealize Operations Manager"

An organization is facing vSAN storage capacity challenges on one of their vSAN enabled clusters, while other vSAN enabled clusters are underutilized. The current vSAN version is 7.0 U1.

Which vSAN feature should be used to resolve this challenge in the quickest way?
A . vSANHCIMesh
B. vSAN Replication
C. vSAN Stretched Clusters
D. vSAN Datastore(s)

Answer: A

Explanation:

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 the hardware compatibility check in the host remediation settings for the images.
C. Enable the quick boot setting in the host remediation settings for the images.
D. Disable HA admission control in the host remediation settings for the baselines.

View Answer

Answer: C

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.

An administrator needs to design a new vSAN cluster to host production mission critical workloads.

Which three topics would impact this design? (Choose three.)

A. The amount of ESXi host memory

B. Effective vSAN datastore capacity

C. The amount of virtual Disks per VM

D. The size of the cache tier according to workload characteristics

E. The supported CPU type of the ESXi host

F. Usage of vSphere DRS

View Answer

Answer: A,D,E

Explanation:

The three topics that would impact the design of a new vSAN cluster to host production mission critical workloads are A. The amount of ESXi host memory, D. The size of the cache tier according to workload characteristics, and E. The supported CPU type of the ESXi host.

The amount of ESXi host memory is important because it determines the amount of memory available to virtual machines, which can impact the performance of the applications running on them.

The size of the cache tier according to workload characteristics is also important as it determines how much write buffer memory is available to the vSAN cluster. This is essential as write buffer memory helps to ensure high performance and low latency. Finally, the supported CPU type of the ESXi host is important as this will impact the performance of the cluster, as well as compatibility with certain applications.
