Dell EMC D-VXR-OE-23 Dell VxRail Operate 2023 Exam Practice Test

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.

Answer : C

In a VxRail deployment, the VMkernel interface used for vSAN traffic is typically vmk1. This interface is designated specifically for vSAN communication, ensuring that the storage traffic is segregated from other types of network traffic for performance and security reasons.

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.

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.

Answer : C

To set up vSAN HCI Mesh, a latency of 10 milliseconds and a bandwidth of 10 Gbps are required. vSAN HCI Mesh allows vSAN clusters to share storage resources over a network. Ensuring low latency and high bandwidth is crucial for maintaining performance and reliability in a hyper-converged infrastructure (HCI) environment, which vSAN HCI Mesh facilitates.

Answer : C

When adding a node to an existing VxRail Cluster and the node is not discovered in the vSphere Client, the 'loudmouth' log should be analyzed. The loudmouth log is crucial for node discovery as it records the communication and discovery processes between nodes in the VxRail cluster. Analyzing this log can help diagnose issues related to node visibility and network communication.

Answer : B, D

When deploying a VxRail Cluster with an existing customer-supplied vCenter Server, two key considerations are:

Supports Enhanced Link Mode with other VxRail-managed vCenter Servers: This allows the existing vCenter Server to link with other VxRail-managed vCenter Servers, providing a unified management interface across multiple vCenter instances, enabling seamless operations and better scalability.

Uses customer-defined procedures for vCenter LCM (Lifecycle Management): Since the vCenter Server is customer-supplied, the procedures for upgrading and maintaining it are defined and managed by the customer, rather than being automatically handled by VxRail's built-in lifecycle management tools.
