Questions # 11:

Which protocol must be configured on the ToR switch to allow automated discovery of a VxRail node?

Options:

Loudmouth

VxLAN

IPv4 multicast

LLDP

IPv6 multicast

Answer

Explanation

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

Questions # 12:

A customer has an existing VxRail vSAN OSA cluster consisting of 5 x E660F nodes.

Which two node types can be added to that cluster? (Choose two.)

Options:

E665F

P670F

E660N

E660

Answer

Explanation

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.

Questions # 13:

What is a benefit of using the VxRail Sizing Tool to size a VDI environment for 1000 users with limited information?

Options:

Guarantees the recommended model performance to support the VDI solution.

Simplifies the deployment of the recommended model to install the VDI software.

Validates the recommended model accommodates the VDI solution.

Automatically configures therecommendedmodel for the VDI solution

Answer

Explanation

The VxRail Sizing Tool validates that the recommended model can accommodate the VDI workload, helping ensure the proposed configuration meets performance requirements even with limited initial information.

Questions # 14:

What are the minimum network bandwidths required for vSAN?

Options:

10 GbE for OSA, 25 GbE for ESA

1 GbE for OSE, 10 GbE for ESA

10 GbE for OSA, 10 GbE for ESA

Answer

Explanation

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.

Questions # 15:

An IT Architect is using the VxRail Sizing Tool. The architect started a new project, provided the project type, and selected the solution type.

What is the next step that the architect needs to undertake to proceed with the process?

Options:

Save the project

Export the result to a report

Size the configuration

Enter workload requirements

Answer

Explanation

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.

Questions # 16:

What is a result of using the VxRail Sizing Tool to size a new cluster?

Options:

The lowest price solution is the recommended configuration.

The highest price solution is the recommended configuration.

Single workloads are only considered when sizing the new cluster.

Answer

Explanation

The VxRail Sizing Tool focuses on the specific workload requirements provided, sizing the cluster based on single or combined workload profiles rather than price considerations.

Questions # 17:

What is the minimum number of nodes required for erasure coding with FTT=2 in a vSAN ESA cluster?

Options:

5 nodes

4 nodes

3 nodes

6 nodes

Answer

Explanation

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.

Questions # 18:

An architect must deploy the Live Optics tool to gather information from an existing customer environment.

What is the correct way to begin this process?

Options:

Answer

Explanation

The correct process is to sign up on the Live Optics website, download the collector, and deploy it on a suitable workstation or server in the environment to gather data without impacting the vCenter Server directly.

Questions # 19:

What are two reasons to provide minimum ceiling clearance above a VxRail rack? (Choose two.)

Options:

Room for forklift

Sprinkler system

Service access

Anti-static protection

Airflow management

Answer

B, E

Explanation

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.

Questions # 20:

A customer is planning to expand an existing VxRail vSAN cluster. Their current rack is full, so the cluster has to expand to an additional rack. Due to networking requirements, each rack is a Layer 2 boundary, so the new nodes require new management, vSAN, and vMotion subnets.

When designing the solution, what are two considerations that the architect should consider? (Choose two.)
