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

Answer : B, C, D

The three data protection options included with VxRail are:

vSphere Replication: Provides simple and cost-effective replication of virtual machines for data protection and disaster recovery. It allows users to replicate VMs between different vSphere environments.

vSAN Stretched Cluster: Offers high availability and disaster recovery by stretching a single vSAN cluster across two geographically separated sites. It ensures data redundancy and site-level failure protection.

RecoverPoint for VMs: Provides continuous data protection and disaster recovery for VMware virtual machines. It enables point-in-time recovery and ensures minimal data loss in the event of a failure.

Answer : B

When adding VxRail nodes based on a different chipset (e.g., AMD vs. Intel) to an existing cluster, it is necessary to enable VMware Enhanced vMotion Compatibility (EVC) mode. EVC ensures CPU compatibility for vMotion by masking certain CPU features, making it possible to add nodes with different processors to the same cluster without causing compatibility issues.

Steps:

Enable VMware EVC mode on the existing cluster.

Ensure all cluster nodes meet the EVC requirements.

Add the new AMD-based nodes to the existing cluster.

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.

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

When scaling a VxRail cluster, it is important to consider that mixing VxRail nodes with different base network speeds is not permitted. This restriction ensures network consistency and performance across the cluster, avoiding potential issues with data flow and latency caused by differing network speeds.

Answer : B

A significant benefit when using VCF (VMware Cloud Foundation) on VxRail architectures is the automation of full stack lifecycle management. VCF on VxRail integrates VMware Cloud Foundation with Dell EMC VxRail, providing an automated and turnkey hybrid cloud solution. This integration automates the deployment, configuration, and ongoing management of the entire stack, including hardware, virtualization, and cloud management, thereby reducing complexity and administrative overhead.

Answer : C

For a VxRail cluster deployed with four VxRail E560 nodes using four integrated NIC ports and the default network profile, the VxRail management traffic is carried by vmnic0 and vmnic1 in an active/standby configuration with no link aggregation. This setup ensures redundancy and failover capabilities for the management network, enhancing the cluster's reliability and resilience.
