EMC Dell VxRail Design D-VXR-DS-00 Exam Dumps: Updated Questions & Answers (December 2025)

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.

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.

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

VD-4510 with 3 NVMe SSDs and 25 GbE networking is a valid ESA node configuration optimized for performance with NVMe storage and higher bandwidth.

E660N with 3 NVMe SSDs and 10 GbE networking also qualifies as a valid ESA node configuration balancing NVMe storage with 10 GbE network connectivity.

For proper network resolution in a VxRail deployment using external DNS, valid lookup records are required for vCenter Server, ESXi hosts, and discovery addresses to ensure all critical components can be located and communicate correctly.

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.

Selecting 1 failure tolerance with RAID 5 (Erasure Coding) causes each front-end write to generate 4 backend I/Os due to the parity calculations and data striping involved, impacting storage performance accordingly.

Automatic node discovery requires the internal management VLAN to be properly configured on the switches for node communication, and the switches must allow IPv4 multicast traffic to enable discovery protocols to function correctly.

For VxRail, vSAN requires a minimum of 10 GbE bandwidth for Older Software Architectures (OSA) and 25 GbE for Enhanced Software Architectures (ESA) to meet performance and reliability standards.

The PowerStore 5200T connected via NVMe/TCP supports integration with a VxRail-managed vCenter on the local cluster, enabling optimized storage performance and management within the VxRail ecosystem.
