Dell EMC D-VXR-OE-23 Dell VxRail Operate 2023 Exam Practice Test
Question 1
Which vSphere integrated component must be installed on the VxRail cluster that is used to run containers?
Answer : A
The vSphere integrated component that must be installed on the VxRail cluster to run containers is VMware Tanzu. VMware Tanzu enables Kubernetes container orchestration within a VMware environment, integrating with vSphere to provide a platform for managing containers alongside virtual machines. This allows administrators to deploy and manage containerized applications using the same tools and processes they use for VMs.
Question 2
What is the maximum number of remote vSAN data stores a client cluster can mount using vSAN HCI Mesh?
Answer : D
The maximum number of remote vSAN data stores a client cluster can mount using vSAN HCI Mesh is 6. VMware vSAN HCI Mesh allows for the mounting of remote vSAN datastores to provide flexible storage solutions and scalability. This feature enables multiple clusters to share storage resources efficiently.

Question 3
Which VxRail networks support link aggregation1?
Answer : C
In VxRail networks, the vSAN and vMotion networks support link aggregation. Link aggregation (also known as NIC teaming) allows multiple network interfaces to be combined into a single logical interface, providing redundancy and increased throughput. This is particularly beneficial for vSAN traffic, which requires high bandwidth and low latency, and vMotion traffic, which benefits from increased network performance during virtual machine migrations.

Question 4
SIMULATION
A VxRail administrator is concerned about security and wants to protect the vSAN storage against unauthorized access (for both data on disk and in flight.)
Use the simulator to enable the relevant services. A vSphere Native Key Provider has already been configured.
Answer : A
To protect the vSAN storage against unauthorized access for both data on disk and in-flight, enable vSAN data-at-rest encryption and data-in-transit encryption. Follow these steps:
Log in to vSphere Client:
Open the vSphere Client.
Enter the username: administrator@vsphere.local.
Enter the password: VMw@r3!123.
Click Login.
Navigate to vSAN Cluster Settings:
In the left-hand navigation pane, expand VxRail-DC and select VxRail-Cluster.
Click on the Configure tab.
Enable vSAN Data-at-Rest Encryption:
Under the vSAN section, select Services.
Click on Data-at-Rest Encryption.
Click Edit to configure encryption settings.
Ensure that the Enable Data-at-Rest Encryption checkbox is selected.
Choose the vSphere Native Key Provider that has already been configured.
Click Apply to enable data-at-rest encryption.
Enable vSAN Data-in-Transit Encryption:
Under the same vSAN section, select Services.
Click on Data-in-Transit Encryption.
Click Edit to configure encryption settings.
Ensure that the Enable Data-in-Transit Encryption checkbox is selected.
Click Apply to enable data-in-transit encryption.
Verify Configuration:
Return to the vSAN > Services section.
Ensure that both Data-at-Rest Encryption and Data-in-Transit Encryption are enabled and show as active.
Verify that there are no error messages indicating configuration issues.
Steps using the Simulator:
Login to vSphere Client:
Open the simulator and navigate to the vSphere Client interface.
Log in using the credentials:
Username: administrator@vsphere.local.
Password: VMw@r3!123.
Navigate to vSAN Settings:
In the vSphere Client interface, expand VxRail-DC and select VxRail-Cluster.
Click on the Configure tab on the right.
Enable Data-at-Rest Encryption:
Under vSAN, click Services.
Find Data-at-Rest Encryption and click Edit.
Check the box for Enable Data-at-Rest Encryption.
Select the vSphere Native Key Provider.
Click Apply.
Enable Data-in-Transit Encryption:
Still under vSAN > Services, find Data-in-Transit Encryption and click Edit.
Check the box for Enable Data-in-Transit Encryption.
Click Apply.
Verification:
Check the status of both encryption services under vSAN > Services to ensure they are enabled and operational.
VMware vSAN Security Guide: vSAN Security
=========================
By enabling both data-at-rest and data-in-transit encryption, you can protect the vSAN storage from unauthorized access and ensure data security both on disk and during transit.
Question 5
What is the vSAN automatic rebalancing threshold recommended by VMware?
Answer : D
The recommended vSAN automatic rebalancing threshold by VMware is 20%. This threshold ensures that vSAN automatically initiates rebalancing operations when the storage utilization across the disks in the vSAN datastore becomes uneven beyond this threshold, maintaining optimal performance and storage efficiency.
Question 6
If the vCenter Server is unavailable, which vSAN troubleshooting option should an administrator use?
Answer : D
If the vCenter Server is unavailable, an administrator should use VxRail Manager for vSAN troubleshooting. VxRail Manager provides comprehensive management and monitoring capabilities for the VxRail cluster, including vSAN. It enables administrators to perform health checks, diagnostics, and maintenance tasks even when the vCenter Server is down, ensuring continuity of operations and effective troubleshooting.

Question 7
SIMULATION
An existing 4-node VxRail standard cluster has to be scaled out with 2 additional nodes and
configured as a stretched cluster. An administrator must prepare a vSAN storage policy that should
have the following:
- vSAN Policy Name: vSAN
Stretched Cluster
- Data protection across the sites
- Local protection: RAID-1 with
FTT=1
- Thick Provisioning
An administrator should be able to provision a VM even if the currently available cluster
resources cannot satisfy the current policy.
Use the simulator to create the required vSAN storage policy.
Answer : A
To create the required vSAN storage policy in the vSphere Client for a VxRail stretched cluster, follow these steps:
Log in to vSphere Client:
Open the vSphere Client.
Enter the username: administrator@vsphere.local.
Enter the password: VMw@r3!123.
Click Login.
Navigate to Storage Policies:
From the home screen, go to Policies and Profiles in the left-hand navigation pane.
Click on VM Storage Policies.
Create a New Storage Policy:
Click Create VM Storage Policy.
Enter the name as vSAN Stretched Cluster.
Click Next.
Configure Policy Rules:
In the Policy Structure section, choose Enable tag-based placement rules if needed.
Click Next.
Add vSAN Rules:
In the Storage Compatibility section, click Add rule and select vSAN.
Configure the following:
Primary level of failures to tolerate (PFTT): 1 failure - RAID 1 (Mirroring)
Secondary level of failures to tolerate (SFTT): 1 failure - RAID 1 (Mirroring)
Failures to Tolerate: 1
Provisioning type: Thick Provisioning
Ensure 'Force Provisioning' is enabled. This allows the VM to be provisioned even if the current resources do not satisfy the policy.
Set Data Services:
Skip the Data Services section if not applicable.
Click Next.
Review and Finish:
Review the policy settings.
Click Finish to create the storage policy.
Apply the Storage Policy to VMs:
Navigate to the VMs section.
Select the VMs that need the new storage policy.
Right-click and select VM Policies > Edit VM Storage Policies.
Choose the vSAN Stretched Cluster policy for the applicable disks.

=========================
Note: The exact steps may vary slightly based on the version of vSphere Client being used. Make sure to adjust any specific configurations based on the latest guidelines and available features in the interface.
