Topic 2, Performance Based Questions
You must use the VxRail Simulator to correctly answer questions in Part 2. The simulator allows you to use the VxRail interface and configure many items. You are scored on your ability to perform tasks, configure items, and gather information within the simulated environment.
Question 4
SIMULATION
Task
An administrator is working with the VxRail Dell Support team and as part of the troubleshooting, the admin has been instructed to temporarily remove the node with a serial number of "V0730040000000" from the cluster.
User credentials are Username of
"administrator@vsphere.local"
Password "VMw@r3!123".
Using the simulator, identify the correct node and remove it from the cluster.
Answer : A
To temporarily remove a node with a specific serial number from the VxRail 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.
Identify the Node with Serial Number 'V0730040000000':
In the vSphere Client interface, navigate to the Hosts and Clusters view.
Expand the VxRail-DC and then the VxRail-Cluster.
Locate the Node:
Click on each host (e.g., vcluster730-esx01, vcluster730-esx02, vcluster730-esx03, vcluster730-esx04) and check the Summary tab to identify the node with the serial number V0730040000000.
The Summary tab provides details about the hardware, including the serial number.
Put the Node in Maintenance Mode:
Right-click on the identified node.
Select Maintenance Mode > Enter Maintenance Mode.
Select Ensure Accessibility and click OK.
Remove the Node from the Cluster:
Once the node is in maintenance mode, right-click the node again.
Select Remove from Inventory.
Confirm the action by clicking Yes or OK when prompted.
Verify the Node Removal:
Ensure that the node is no longer listed under the VxRail-Cluster.
Check the overall health and status of the cluster to confirm that it is functioning properly without the removed node.

=========================
Note: Be cautious when removing nodes from a VxRail cluster, as this can impact the cluster's capacity and redundancy. Always follow proper procedures and consult with Dell Support as needed.
Question 5
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.
