EMC D-VXR-DS-00 Dell VxRail Design Exam Practice Test

VxRail Manager is always present on a VxRail cluster as the core management component that handles cluster lifecycle, updates, and monitoring.

VxRail Dynamic Nodes enable the use of vSAN storage from an existing VxRail cluster.

They support integration with existing supported external storage arrays.

They allow use of external storage alongside local vSAN for tiering and optimized storage management.

Site disaster tolerance set to Site Mirroring (stretched cluster) combined with RAID 1 mirroring provides fault tolerance against site failure with the ability to tolerate 2 failures or 1 failure respectively, ensuring data availability during a single data center outage.

The witness appliance is the same for both vSAN ESA and OSA architectures, providing consistency across deployments.

The witness can be managed by a separate vCenter server than the one managing the VxRail cluster, allowing flexible management options.

For erasure coding with a Failure to Tolerate (FTT) of 2 in a vSAN ESA cluster, a minimum of 5 nodes is required to provide the necessary redundancy and data protection.

After selecting the project and solution type in the VxRail Sizing Tool, the next step is to enter the workload requirements to tailor the sizing and configuration recommendations accurately.

To maintain compatibility in a vSAN OSA cluster, node types that match the existing architecture, such as E660N and E660, can be added, ensuring consistent hardware and software support.

Live Optics collects and provides detailed virtualization, storage, and network workload metrics that can be imported into the VxRail Sizing Tool to inform accurate sizing and planning.

LLDP (Link Layer Discovery Protocol) must be configured on the ToR switch to enable automated discovery of VxRail nodes during deployment.

The cluster is replacing an existing infrastructure, which aligns with a Technology Refresh purpose, and supporting Hadoop and Tableau workloads fits the Big Data use case in the VxRail Sizing Tool.

Sprinkler systems require adequate ceiling clearance for proper fire suppression coverage.

Airflow management needs sufficient clearance above the rack to maintain cooling efficiency and prevent overheating.

VxRail Dynamic Nodes are specified when a customer wants to refresh their server environment but already has a PowerStore 5200T storage array, allowing integration of external storage with VxRail compute nodes.
