  Where can the consultant find this information?

  A. Handover checklist
  B. Test plan
  C. Operations Guides
  D. As-Built Guide
  B. Test plan

  ---

  Explanation/Reference:

  The Test Plan is the most appropriate resource for detailed information on network validation testing. This document typically outlines the specific tests to be conducted to ensure the network meets the required specifications and performance standards necessary for a stable and efficient Nutanix environment. The Test Plan provides a structured approach to validate each network component and interaction, ensuring all aspects are tested and meet design and operational requirements. References: Nutanix Installation and validation procedures as described in Nutanix official documentation and training modules from Nutanix University.

• Question 23:

  A consultant creates three storage containers (container-1, container-2, container-3). The customer requires that only container-1, which will be utilized as an NFS datastore, be presented to external hosts.

  However, users are able to mount all three containers.

  What is causing this problem?

  A. Compression was turned on for all containers.
  B. A Container-level whitelist entry was configured.
  C. Deduplication was turned on for all containers.
  D. A Global whitelist entry was configured.
  A. Compression was turned on for all containers.
  B. A Container-level whitelist entry was configured.
  C. Deduplication was turned on for all containers.
  D. A Global whitelist entry was configured.

• Question 24:

  What reference materials should be provided to the customer during the Knowledge Transfer?

  A. Questionnaire, technical slides and checklist, links to documentation and resources
  B. As-Built Guide, technical slides and checklist, Network Diagram
  C. As-Built Guide, Project Plan, links to documentation and resources
  D. As-Built Guide, technical slides and checklist, links to documentation and resources
  D. As-Built Guide, technical slides and checklist, links to documentation and resources

  ---

  Explanation/Reference:

  During the Knowledge Transfer phase, providing the customer with the As-Built Guide, technical slides and checklists, along with links to documentation and resources, is optimal. This set of materials ensures the customer receives both detailed and high-level information, supporting a thorough understanding of the deployment and operational procedures, and it allows for easy reference to official resources for ongoing needs.References: The Nutanix Bible, NCS-Core 6.8 learning documentation, and best practices in IT project documentation.

• Question 25:

  Which two files should be downloaded to deploy Foundation VM on VMware ESXI or AHV Hypervisors? (Choose two.)

  A. foundation_VM-version-disk-0.geow2
  B. foundation_VM-version. tar
  C. foundation_VM-version. vmdk
  D. foundation-version.tar.gz
  B. foundation_VM-version. tar
  C. foundation_VM-version. vmdk

  ---

  Explanation/Reference:

  To deploy the Foundation VM on VMware ESXi or AHV Hypervisors, the two necessary files are:

  1.

  foundation_VM-version.tar which contains the complete Foundation VM package.

  2.

  foundation_VM-version.vmdk, which is the virtual disk file for VMware environments.

  These files are required to create and boot the Foundation VM in these hypervisor environments, facilitating the deployment and configuration of the Nutanix nodes within the cluster. References : Nutanix Bible, Nutanix University NCS-Core

• Question 26:

  Refer to the exhibit.

  

  A consultant migrated multiple VMs to a new cluster. VMs were previously in VLAN 10. Why can the VMs no longer communicate on their network?

  A. The VNIC type should be set to VMXNET2.
  B. The GuestOS firewall is blocking traffic in the new cluster.
  C. The VLAN ID is incorrect.
  D. Static IP addresses have not been assigned to the new VMs.
  C. The VLAN ID is incorrect.

  ---

  Explanation/Reference:

  In scenarios where VMs have been migrated to a new cluster and they were previously on VLAN 10 but can no longer communicate, the most likely cause is that the VLAN ID setting on the virtual network interface cards (VNICs) of the VMs

  does not match the VLAN configuration of the new network. Ensuring that the VLAN IDs are correctly set to match the network configuration of the new cluster is essential for proper network communication.

• Question 27:

  What is the minimum number of nodes required for a Nutanix Cluster to support Replication Factor 3 (RF3) on a storage container?

  A. 3
  B. 4
  C. 5
  D. 6
  C. 5

  ---

  Explanation/Reference:

  For a Nutanix cluster to support Replication Factor 3 (RF3), a minimum of 5 nodes is required. RF3 means that three copies of the data are maintained across the cluster for fault tolerance and high availability. Having at least five nodes

  ensures that there are sufficient nodes to distribute these copies across different fault domains, minimizing the risk of data loss and providing improved resilience against node failures.

• Question 28:

  An organization is planning an upgrade to AOS 5.15 and wants to understand which cluster products and/or services are supported for physical traffic isolation. Which Nutanix component supports its network traffic being isolated onto its own virtual network?

  A. Volumes
  B. Objects
  C. Containers
  D. Files
  A. Volumes

• Question 29:

  A new Nutanix customer suspects that network traffic is going over the 1G interfaces instead of the 10G interfaces. How should a consultant confirm that the traffic is only traversing the 10G interfaces?

  A. Look in Prism Element under Network.
  B. Run the allssh manage_ovs show interfaces command.
  C. Run the iconfig command on the CLI of each CVM.
  D. Run the allssh manage ovs show uplinks command.
  B. Run the allssh manage_ovs show interfaces command.

  ---

  Explanation/Reference:

  To confirm that network traffic is traversing the 10G interfaces and not the 1G interfaces in a Nutanix environment, the consultant should run the allssh manage_ovs show interfaces command. This command allows for the inspection of all interface configurations and their current operational status across the cluster, effectively confirming which interfaces are actively managing traffic.References: Nutanix Bible, Nutanix University NCS-Core 6.8 learning materials

• Question 30:

  Refer to the exhibit.

  What are two descriptions of how Files perform quota management? (Choose two.)

  A. User 2 can continue to add another 3GB file but will receive a daily notification email.
  B. User 1 can continue to add another 5GB file but will receive a daily notification email.
  C. User 1 can add an 8GB file to the share without receiving notification.
  D. User 2 can add an 8GB file without receiving a notification email.
  B. User 1 can continue to add another 5GB file but will receive a daily notification email.
  D. User 2 can add an 8GB file without receiving a notification email.
