NEW QUESTION 33
In a stretched vSAN cluster, how is Read Locality established after fail over to the secondary site?
- A. 100% of the reads comes from vSAN hosts on the local site
- B. 100% of the reads comes from vSAN hosts on the remote site
- C. 50% of the reads comes from vSAN hosts on the local site
- D. 50% of the reads comes from vSAN hosts on the remote site
Answer: B
Explanation:
In the event of a failure or maintenance event, the virtual machine is restarted on the remote site. The 100% rule continues in the event of a failure. This means that the virtual machine will now read from the replica on the site to which it has failed over. One consideration is that there is no cached data on this site, so cache will need to warm for the virtual machine to achieve its previous levels of performance.
NEW QUESTION 34
A company has deployed a 12-node (6-6-1) vSAN 7.0 stretched cluster for all production workloads.
The customer currently uses four different vSAN storage policies for running the workloads depending on the applications requirements:

* Policy 2 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring
* 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.
Which two activities should the administrator complete to ensure that there is no impact to production services during the maintenance window in the Preferred Site? (Choose two.)
- A. Update vSphere DRS site affinity rules so that Preferred Site workloads should not run on hosts in DC1.
- B. Change the FTT setting in Policy 3 to be "Erasure Coding".
- C. Change the Site Disaster Tolerance setting in Policy 4 to be "None - Keep Data on Preferred".
- D. Update vSphere DRS site affinity rules so that Preferred Site workloads must run on hosts in DC2.
- E. Change the Site Disaster Tolerance setting in Policy 3 to be "Dual Site Mirroring".

NEW QUESTION 37
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. Enable Data-In-Transit encryption first
- C. Create an encryption storage policy
- D. Verify if a role with privilege "Cryptographic operations.Migrate" is assigned
- E. Verify if a role with privilege "Cryptographic operations.Encrypt new" is assigned
- F. Enable that the virtual machines are powered on
Answer: A,C,E
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

* vSAN 7.x Cluster
* vSAN node count: 8
* De-Duplication and Compression: Enabled.
* Encryption: Disabled

- B. Replace the failed disk with a storage device that is identical in class and capacity.
- C. Remove the affected Disk from the Disk Group, and choose Full Data Migration.
- D. Replace the failed disk with a storage device that is identical in class but smaller in capacity.
- E. Remove the affected Disk Group from the vSAN Cluster, and choose Full Data Migration.
- F. Remove the affected Disk Group from the vSAN Cluster, and choose No Data Migration.
Answer: A,B,C
Explanation:
If you upgrade the capacity device, verify the following requirements:
- Verify that the cluster contains enough space to migrate the data from the capacity device.
- Place the host in maintenance mode. See Place a Member of Virtual SAN Cluster in Maintenance Mode.
"Select the flash capacity device or magnetic disk, and click Remove selected disk(s) from disk group."

NEW QUESTION 40
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
