At ValidExamDumps, we consistently monitor updates to the Dell EMC D-VXR-OE-23 exam questions by Dell EMC. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Dell EMC Dell VxRail Operate 2023 exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Dell EMC in their Dell EMC D-VXR-OE-23 exam. These outdated questions lead to customers failing their Dell EMC Dell VxRail Operate 2023 exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Dell EMC D-VXR-OE-23 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
An environment has two VxRail clusters In vCenter there is only one vSphere Distributed Switch object for both clusters Which deployment architecture was used for these clusters?
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.

What are two failure states of vSAN components? (Select 2)
The two failure states of vSAN components are 'Degraded' and 'Absent.'
Degraded: A vSAN component is considered degraded when it is still accessible but has experienced a loss of redundancy or other performance issues. This state indicates that the data is still available but may be at risk if further failures occur.
Absent: A vSAN component is in an absent state when it is temporarily unavailable, often due to transient issues like network disconnections or host reboots. The system expects the component to return shortly.
Which level of data protection can be configured across sites in a VxRail Stretched Cluster1?
In a VxRail Stretched Cluster, RAID 1 can be configured across sites to provide data protection. RAID 1 (mirroring) ensures that data is replicated across two sites, providing high availability and data redundancy in case one site fails. This configuration helps maintain continuous operations and data integrity in a multi-site deployment.
A VxRail administrator is adding a node to an existing VxRail Cluster The node has been racked, cabled and powered on However, the node is not discovered in the vSphere Client
Which log file should be analyzed to diagnose the issue?
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.

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.
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.
