* Policy 3 - Site Disaster Tolerance=None - Keep Data on Preferred, FTT=Mirroring
* Policy 4 - Site Disaster Tolerance=None - Keep Data on Non-Preferred, FTT=Mirroring During the setup of the vSAN stretched cluster, the following VM/Host Rules were created:
* Preferred Site - Preferred Site workloads should run on DC1 hosts.
* Secondary Site - Secondary Site workloads should run on DC2 hosts.

A customer is planning to migrate their physical Microsoft SQL Server clustered workloads to vSAN enabled vSphere clusters.
The following requirements must be met:
* Each MSSQL cluster is made up of 3 nodes
* Highest possible availability against node failures
* Some of the vSAN clusters will only consume storage

NEW QUESTION 43
An administrator is tasked to create a custom storage policy for workloads and is including additional disk stripes while defining the storage policy.
What is the main purpose of this practice?
- A. To reconstruct corrupted data
- B. To set a failure tolerance
- C. To increase available storage space
- D. To improve performance
Answer: D
Explanation:
https://blogs.vmware.com/virtualblocks/2016/09/19/vsan-stripes/ Striping may help performance if certain virtual machines are I/O intensive and others are not.
The "number of disk stripes per object" storage policy rule attempts to improve performance by distributing data contained in a single object (such as a VMDK) across more capacity devices. https://blogs.vmware.com/virtualblocks/2021/01/21/stripe-width-improvements-in-vsan-7-u1/
NEW QUESTION 44
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.)
- A. Establish a trusted connection with the KMS
- B. Verify if a role with privilege "Cryptographic operations.Encrypt new" is assigned
- C. Verify if a role with privilege "Cryptographic operations.Migrate" is assigned
- D. Enable Data-In-Transit encryption first
- E. Enable that the virtual machines are powered on
- F. Create an encryption storage policy
Answer: A,B,F
Explanation:
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. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.security.doc/GUID-7DE1ED8F-880B-421E-B27B-5AAA58454AFA.html

- A. SFTT = 1
- B. PFTT = 0
- C. PFTT = 1
- D. SFTT = 0
Answer: B
Explanation:
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/
