DELL D-VXR-OE-23 Practice Test - Questions Answers

Before the VxRail Market can be accessed via the VxRail Plugin, an active Dell Technologies support account must be linked to VxRail Manager. This linkage is necessary to verify entitlements and ensure that the user has access to the latest updates, support resources, and additional software available through the VxRail Market.

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.

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: [email protected].

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.

To enable the system LED on vcluster730-esx03.edu.local for identification in the physical rack, follow these steps:

Log in to vSphere Client:

Open the vSphere Client.

Enter the username: [email protected].

Enter the password: VMw@r3!123.

Click Login.

Navigate to the Host:

In the vSphere Client interface, navigate to the Hosts and Clusters view.

Expand the VxRail-DC and then the VxRail-Cluster.

Select the host named vcluster730-esx03.edu.local.

Access Host Actions:

Right-click on vcluster730-esx03.edu.local.

From the context menu, select Actions.

Enable System LED:

In the Actions menu, locate and select Enable LED or Turn On Locator LED (the exact wording might vary).

Confirm the action if prompted.

Verify LED Activation:

Check the physical rack to ensure that the system LED on vcluster730-esx03.edu.local is enabled and the node is easily identifiable.

=========================

Note: The exact steps to enable the LED might vary slightly based on the version of vSphere Client you are using, but the general process involves selecting the host and using the Actions menu to enable the system LED.

The deployment architecture used for these clusters, where there is only one vSphere Distributed Switch object for both clusters in vCenter, is 'External vCenter Server with external DNS.' This setup allows for centralized management of multiple clusters and network resources using a single vSphere Distributed Switch, facilitated by an external vCenter Server and DNS configuration.

By default, the vSAN Skyline Health check runs every 60 minutes. This regular interval ensures that the health status of the vSAN environment is frequently assessed, allowing administrators to promptly address any issues that may arise.

When the VxRail cluster is deployed, the vSAN storage policy settings applied to the VxRail Manager VM are as follows:

Failures to Tolerate: 1 failure - RAID 1 (Mirroring)

Object space reservation: Thin provisioning

These settings ensure that the VxRail Manager VM has redundancy to tolerate a single failure and uses thin provisioning to optimize storage usage.

If the validation process for shutting down a VxRail cluster fails, the necessary action to correct the issue is to shut down all client VMs. Ensuring that all virtual machines are powered off is crucial for a clean shutdown of the cluster, preventing any data loss or corruption and allowing the shutdown process to complete successfully.

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.
