Question 1

A consultant and customer agree on a scope of services regarding the deployment of a new Nutanix cluster.

Which two products does this scope apply to? (Choose two.)



Answer : A, D

The scope of services for the deployment of a new Nutanix cluster would apply to both Foundation and Prism Central. Foundation is the initial software used for deploying Nutanix nodes and creating clusters, essential for setting up the environment. Prism Central is used for managing multiple clusters and is integral to the operational scope of the service, providing centralized management capabilities.

Question 2

A consultant is setting up Prism Central to manage multiple Nutanix clusters. The customer requires til redundancy and tre aby to manage up to 12,500 VMs.

Which deployment option should the consultant use to meet the requirements?



Answer : C

To meet the customer's requirements for high availability and the ability to manage up to 12,500 VMs, the consultant should use Prism Central Scale-out deployment. This deployment mode allows Prism Central to be scaled out across multiple instances, significantly enhancing both performance and resilience, ensuring that the management and operations of a large number of VMs can be handled efficiently and without a single point of failure.

Question 3

A consultant is unable to ping the CVM from the hypervisor using the external interface. The customer's network is configured with the 10.3.12.0/24 subnet without VLAN tagging. The CVM and hypervisor are using the same address space.

What is causing this issue?



Answer : B

If a consultant is unable to ping the CVM from the hypervisor using the external interface in a network without VLAN tagging, and both are using the same subnet, the issue might be related to an incorrect default gateway configuration. The default gateway must be correctly set to ensure proper routing of packets between the CVM and the hypervisor. An incorrect gateway can prevent successful communication even if both devices are on the same subnet. Reference:

Question 4

A consultant discovers that while the Foundation VM and the consultant's laptop are able to ping each other nodes are rea discovered while trying to run Foundation on the customer's network.

What should the consultant do to resolve the issue?



Answer : C

When Foundation VM and a laptop can ping each other but nodes are not being discovered, it suggests a network protocol issue. The consultant should enable IPv6 and multicast on the switch. Multicast is required for node discovery in many environments, especially when using Nutanix Foundation, as it helps in the detection and communication between nodes and the Foundation VM.

Question 5

A customer has an ESXi cluster with two 10GbE NICs on each node and the following requirements.

Solution must follow Nutanix Best Practices

Network configuration should be redundant

A vSphere Distributed Switch will be utilized

Which load balancing configuration should be used?



Answer : A

For a customer using an ESXi cluster with two 10GbE NICs on each node and a vSphere Distributed Switch, the recommended load balancing configuration, following Nutanix Best Practices for redundancy and efficiency, is 'Route based on IP hash.' This setting allows for optimal utilization of network bandwidth and redundancy by distributing the traffic based on the IP address pairings, ensuring a balanced load across the physical NICs.

Question 6

A consultant is onsite with a customer to expand an existing eight-node cluster with four new GPU nodes. The consultant plugs the nodes into the network switch and follows the procedure to expand the cluster in Prism Element, but the new nodes cannot be found.

Which issue is preventing the new nodes from being discovered?



Answer : A

If new GPU nodes cannot be found during an attempt to expand an existing cluster:

A . IPMI is not plugged into the network: IPMI must be connected and functional for node discovery and management during expansion processes. If IPMI ports are not connected to the network, the nodes will not be discoverable in Prism Element.

Question 7

A customer recently bought services from their consultant to re-configure an existing Cluster for a new use case. The data on the cluster is not important. The customer does not know the CVM usernames and passwords.

Which Foundation tool should the consultant use to resolve this issue?



Answer : C

For re-configuring an existing cluster for a new use case where data preservation is not a concern, and there is a lack of CVM credentials:

C . Foundation VM - Bare Metal: This tool allows for a complete re-installation of the Nutanix software from scratch, which is ideal in scenarios where existing configurations and data are no longer needed, and access credentials are unknown or lost.
