NEW QUESTION 31
An administrator has changed the Virtual Machine Storage Policy from RAID-5 to RAID-6.
How many failures can be tolerated when this change is made?

NEW QUESTION 32
An administrator wants to check the performance metrics for the workloads and their virtual disks that are running on a vSAN cluster, but no statistical charts are displayed in the vSphere client.
Why is this behavior being seen?

vSAN network diagnostic mode is not enabled.

vSAN proactive tests haven’t been run yet.

vSAN performance service is turned off.

vSAN performance verbose mode is not enabled.

Some tools allow for measuring latency peaks. This unfortunately isn’t ideal, as it can unfairly represent statistical outliers, which may very well occur when there is little to no I/O activity. The best way to understand the actual behavior of VM and application latencies is to observe in time based performance graphs. Depending on the level of detail, you may need to measure at the individual VMDK level. Become familiar with these graphs to determine what is normal, and what is not for that given application. This is where you can use built-in functionality of vCenter and the vSAN performance service metrics to gather this information.

NEW QUESTION 33
In a vSAN stretched cluster, which value must be set in the vSAN policy if there is no requirement for data mirroring across sites?

SFTT = 0

SFTT = 1

PFTT = 1

PFTT = 0

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/

NEW QUESTION 34
An architect is working with vSAN and setting the fault domains to support FTT=1.
How many fault domains will be needed?

NEW QUESTION 35
In a vSAN stretched cluster, which value must be set in the vSAN policy if there is no requirement for data mirroring across sites?

SFTT = 0

SFTT = 1

PFTT = 1

PFTT = 0

Primary level of failures to tolerate (PFTT). For stretched clusters, PFTT defines the number of site failures that a virtual machine object can tolerate. For a stretched cluster, only a value of 0 or
1 is supported.
Secondary level of failures to tolerate (SFTT). For stretched clusters, SFTT defines the number of additional host failures that the object can tolerate after the number of site failures defined by PFTT is reached. If PFTT = 1 and SFTT = 2, and one site is unavailable, then the cluster can tolerate two additional host failures.
The default value is 0, and the maximum value is 3.
So data mirroring across sites = PFTT

NEW QUESTION 36
Which statement accurately describes the result when proper VM Storage Policy Affinity Rules on a stretched vSAN cluster are set?

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

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

Bandwidth is unnecessarily sent across the inter-site link.

Proper policies result in higher inter-site bandwidth utilization.

NEW QUESTION 37
An architect is designing for a production vSAN cluster, and the customer introduced these requirements related to File Services:
– A minimum of 12 files shares.
– 30TB NFS capacity to mount workload VMs.
What should be the architect’s recommendations?

Point out the risks regarding putting the hosts in maintenance mode in terms of FSVM.

Confirm on all of the requirements and move forward with the physical design.

Raise concerns regarding support when running VMs on an NFS share as risk.

Highlight the required number of nodes required for the vSAN cluster as a constraint.

NEW QUESTION 38
An administrator has been tasked with enabling encryption for existing virtual machines on a vSAN cluster.
Which three prerequisites must be satisfied before completing the task? (Choose three.)

Create an encryption storage policy

Enable Data-In-Transit encryption first

Enable that the virtual machines are powered on

Verify if a role with privilege “Cryptographic operations.Encrypt new” is assigned

Verify if a role with privilege “Cryptographic operations.Migrate” is assigned

Establish a trusted connection with the KMS

Because Before you can create encrypted virtual machines, you must create an encryption storage policy. You create the storage policy once, and assign it each time you encrypt a virtual machine or virtual disk.
