D-VXR-DS-00 Sample Questions Answers

In the VxRail Sizing Tool, when enabling compression on VxRail vSAN, the default Compression Filter ratio is set to 2:1. This means that the tool assumes a 2:1 data reduction ratio due to compression, effectively halving the storage requirements for the specified workload. This default setting helps in estimating the storage capacity needed for the deployment, though actual compression ratios may vary based on the specific data characteristics.

Validating the environment before deployment ensures readiness and reduces deployment issues.

Sharing configurations between project members facilitates collaboration and consistency.

Validating the configuration settings helps confirm correct setup prior to deployment.

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.

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.

Assigning resource-intensive networks like vSAN to the higher speed uplinks ensures that critical traffic benefits from the best available network performance, optimizing throughput and maintaining security by separating traffic types appropriately.

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.

Both Layer 2 (L2) and Layer 3 (L3) site-to-site connectivity are supported for VxRail stretched clusters.

Configurations with two nodes plus a witness and four nodes plus a witness are supported cluster sizes for stretched clusters, providing fault tolerance across sites.

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

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.
