D-VXR-DY-23 Sample Questions

  1. Question 1

    Advanced

    Introduction to VxRail · VxRail architecture, models, and use cases

    A solutions architect is designing a VxRail cluster for a financial institution that requires strict physical separation of storage traffic due to regulatory compliance. The proposed solution involves a 4-node E-Series cluster. Which network configuration strategy best satisfies this requirement while adhering to VxRail deployment best practices?

    Answer and explanation

    Correct answer: D

    To achieve strict physical separation (air-gapping) of traffic types as often required by high-security regulations, dedicating specific physical NICs (pNICs) to specific traffic types is the optimal solution. While VLANs provide logical separation and NIOC provides bandwidth guarantees, only dedicated physical uplinks provide physical isolation. VxRail allows mapping specific traffic types to specific physical uplinks during the deployment configuration.

  2. Question 2

    Intermediate

    VxRail Deployment Planning · Network planning and configuration

    During the planning phase for a VxRail deployment, a consultant is verifying the Top-of-Rack (ToR) switch configuration. The environment will use a standard VxRail cluster with vSAN. Which multicast configuration on the physical switches is required for the cluster discovery and vSAN traffic?

    Answer and explanation

    Correct answer: B

    VxRail node discovery relies on IPv4 Multicast (specifically mDNS/Bonjour) on the Management VLAN to locate nodes before initialization. However, vSAN traffic in modern VxRail versions (vSAN 6.6+) uses Unicast, removing the requirement for multicast on the vSAN VLAN.

  3. Question 3

    Intermediate

    Using VxRail Configuration Tools · VxRail Configuration Portal usage

    A deployment engineer is preparing the JSON configuration file using the VxRail Configuration Portal. The customer requires the VxRail cluster to use an existing External vCenter Server. Which of the following IDs or names is strictly required to be accurate in the configuration file to ensure successful validation against the customer's environment?

    Answer and explanation

    Correct answer: B

    When deploying with an External vCenter, the VxRail Manager attempts to place the new cluster into a specific Datacenter object. If the Datacenter Name provided in the JSON configuration does not match the existing vCenter object exactly (case-sensitive), the deployment validation or initialization will fail.

  4. Question 4

    Beginner

    VxRail Hardware Installation and Initialization · Racking and cabling procedures

    You are physically installing a 4-node VxRail E660 series cluster. The site has dual Power Distribution Units (PDUs) in the rack: PDU A and PDU B. To ensure maximum power redundancy according to Dell best practices, how should the power supply units (PSUs) be cabled?

    Answer and explanation

    Correct answer: D

    Best practice for high availability is to distribute power sources. By connecting PSU 1 from every node to PDU A and PSU 2 from every node to PDU B, the cluster can survive the complete failure of either PDU A or PDU B without any node losing power completely.

  5. Question 5

    Intermediate

    VxRail Network Environment Requirements and Initialization · Network validation procedures

    A deployment engineer attempts to initialize a new VxRail cluster but fails immediately during the network validation phase. The error log indicates 'Host name resolution failed'. Upon checking the Network Validation Tool (NVT) report, the forward records are correct. What is the most likely cause of this error?

    Answer and explanation

    Correct answer: D

    VxRail initialization is extremely strict regarding DNS. Not only must the FQDN resolve to the IP (Forward/A Record), but the IP must also resolve back to the FQDN (Reverse/PTR Record). Missing PTR records are a common cause of initialization failure during validation.

  6. Question 6

    Advanced

    Deploying the VxRail Cluster · VxRail initialization with an external vCenter Server

    You are deploying a VxRail cluster using the 'External vCenter' option. The customer provides a vCenter Server Appliance (VCSA) that manages three other clusters. Which specific permission requirement must be met for the VxRail management user account in this scenario?

    Answer and explanation

    Correct answer: A

    For security in shared vCenter environments, the best practice (and requirement) is to grant the VxRail management user the 'Administrator' role specifically on the Datacenter object (and propagated to children) where the cluster will live. Global Root Administrator access is not strictly required if scoped correctly, but the user MUST have full administrative rights over the target Datacenter object to create cluster and host objects.

  7. Question 7

    Intermediate

    VxRail Post-Deployment Procedures · Explain the vSAN configuration settings and configure required vSAN setting post-deployment

    After successfully deploying a VxRail cluster, you need to configure the vSAN Storage Policy to ensure data is protected against a double disk failure. The cluster consists of 6 nodes. Which RAID configuration should you apply in the storage policy?

    Answer and explanation

    Correct answer: D

    To protect against a double failure (FTT=2), you need RAID-6 or RAID-1 (Mirroring) with FTT=2. RAID-6 is the capacity-efficient Erasure Coding method for FTT=2. It requires a minimum of 6 nodes (4 data + 2 parity), which matches the cluster size in the scenario.

  8. Question 8

    Advanced

    VxRail Cluster Upgrade and Expansion · Describe VxRail upgrade requirements and activities

    A customer wants to expand an existing 4-node VxRail P-Series cluster running version 7.0.400. They have purchased a new P-Series node that shipped with version 8.0.000 factory installed. What is the correct procedure to add this node to the cluster?

    Answer and explanation

    Correct answer: B

    VxRail clusters require added nodes to be at the same version or a compatible lower version that can be upgraded during addition. You cannot add a higher-version node to a lower-version cluster without re-imaging. The most efficient and non-destructive path (assuming the customer wants the new features) is to upgrade the cluster to match the new node (or higher). Alternatively, the new node must be RASR re-imaged to the lower version, but upgrading the cluster is generally the preferred forward path.
