D-VXR-DY-02 Sample Questions

  1. Question 1

    Beginner

    Pre-deployment · Prepare VxRail nodes for discovery

    An implementation engineer is preparing a Top-of-Rack (ToR) switch for a new VxRail deployment. To ensure that the VxRail Manager can automatically discover the unconfigured nodes via the Loudmouth protocol, which specific networking feature must be enabled on the management VLAN?

    Answer and explanation

    Correct answer: A

    VxRail uses the Loudmouth protocol for node discovery, which relies on IPv6 multicast. Therefore, IPv6 multicast traffic must be allowed on the native VLAN (or the designated management VLAN) connecting the VxRail nodes. MLD snooping or an MLD querier is often configured to manage this traffic.

  2. Question 2

    Intermediate

    Pre-deployment · Prepare a customer-managed vCenter

    A customer requires their new VxRail cluster to be deployed using an existing, customer-managed vCenter Server. The implementation specialist is validating the prerequisites on the external vCenter.

    Which logical object must already exist in the customer-managed vCenter before initiating the VxRail first-run deployment?

    Answer and explanation

    Correct answer: A

    When deploying VxRail with a customer-managed (external) vCenter, a Datacenter object must exist prior to deployment. The VxRail deployment wizard will create the cluster object (or it can be pre-created, but the datacenter must exist) and the VDS during the installation process.

  3. Question 3

    Advanced

    Pre-deployment · Determine and verify install requirements

    A global enterprise is planning a Layer 3 (L3) VxRail deployment across multiple racks. The architect has mapped out the subnets for Management, vSAN, and vMotion.

    Reviewing the architecture, what is a mandatory requirement regarding the VxRail Manager and vCenter Server IP addressing in this topology?

    graph TD subgraph Rack 1 Node1[VxRail Node 1] Node2[VxRail Node 2] Node3[VxRail Node 3] end subgraph Rack 2 Node4[VxRail Node 4] Node5[VxRail Node 5] end Router[L3 Router] Node1 & Node2 & Node3 --> Router Node4 & Node5 --> Router
    Answer and explanation

    Correct answer: A

    Even in a Layer 3 VxRail cluster deployment where ESXi management, vMotion, and vSAN networks can be routed across racks, the VxRail Manager VM and the vCenter Server VM (if internal) must reside in the same subnet/VLAN to maintain proper management connectivity and function.

  4. Question 4

    Beginner

    Pre-deployment · Determine and verify install requirements

    True or False: When preparing DNS for a new VxRail deployment, both Forward (A) and Reverse (PTR) records are strictly required for the ESXi hosts, VxRail Manager, and vCenter Server.

    Answer and explanation

    Correct answer: A

    True. VxRail pre-installation validation strictly checks for the presence of both Forward (A) and Reverse (PTR) DNS records for all primary infrastructure components (ESXi hosts, vCenter, VxRail Manager). If any are missing, the validation will fail.

  5. Question 5

    IntermediateMultiple answers

    Pre-deployment · Gather needed information for deployment

    During the pre-deployment phase, an engineer is filling out the configuration parameters. Which TWO pieces of information must be provided specifically for the vSAN network? (Select TWO)

    Answer and explanation

    Correct answers: B, E

    The vSAN network requires a starting IP address (which will be incremented for each node) and a VLAN ID to segregate the storage traffic. Hostnames are not assigned to vSAN interfaces, and a Default Gateway is typically only required if routing vSAN traffic (L3), but starting IP and VLAN ID are always required.

  6. Question 6

    Intermediate

    Pre-deployment · Correct basic pre-install validation errors

    A deployment engineer runs the pre-install validation tool on a VxRail Manager before starting the build. The tool reports an error regarding MTU mismatch.

    What is the most common cause of this specific validation failure?

    Answer and explanation

    Correct answer: B

    An MTU mismatch during pre-install validation almost always occurs because the deployment configuration specifies Jumbo Frames (MTU 9000) for vSAN and/or vMotion, but the upstream Top-of-Rack (ToR) switch ports have not been configured to allow frames larger than the default 1500 bytes.
