• Question 72:

  A consultant needs to upgrade the ESXi hosts on a Nutanix cluster from version 6.7 to 7.0. vSphere DRS and wMoton are working properly. The consultant needs to use One-Click Upgrade. Which setting should be verified by the consultant?

  A. vSphere HA is enabled.
  B. Nutanix Prism HA is enabled.
  C. vSphere DRS Automation level is set to Conservative.
  D. DRS automation level on all CVMs is disabled.
  A. vSphere HA is enabled.

  ---

  Explanation/Reference:

  When upgrading ESXi hosts on a Nutanix cluster using One-Click Upgrade, it is crucial to verify that vSphere HA (High Availability) is enabled. This setting ensures that in the event of host failure during the upgrade process, VMs will be automatically restarted on other hosts in the cluster, maintaining availability and minimizing disruption. Verifying this setting is essential to ensure the resilience of the environment during the upgrade.

• Question 73:

  A consultant is planning to use a flat switch for installation.

  What is the network requirement for Foundation VM, CVM, Hypervisor, and IPMI A. Foundation VM, CVM, and Hypervisor must be on the same subnet. IPMI can be on a different subnet.

  B. CVM, Hypervisor, and IPMI must be on the same subnet. Foundation VM can be on a different subnet.
  C. Foundation VM and CVM must be on the same subnet. Hypervisor and IPMI can be on a different subnet.
  D. Foundation VM, CVM, and IPMI must be on the same subnet. Hypervisor can be on a different subnet.
  A

  ---

  Explanation/Reference:

  In a typical Nutanix deployment using a flat switch, the Foundation VM, the CVM, and the Hypervisor should all be on the same subnet to facilitate seamless communication and management operations during the initial setup and operation.

  The IPMI, being a management interface, can be on a different subnet as it serves a different purpose primarily for remote management at the hardware level and does not need to be on the same subnet as the other components for cluster

  functionality.

• Question 74:

  A consultant is imaging a Nutanix cluster with VMware ESXi. Foundation returns an error that the media is not a supported ISO. The consultant checks the whitelist file in Foundation and confirms that the version of the ISO is not listed.

  Which three actions should the consultant take to resolve this issue? (Choose three.)

  A. Replace and save whitelist file in Foundation
  B. Obtain the MD5 checksum of the ISO and confirm MD5 checksum of ISO is listed.
  C. Download the iso_whitelist.json from the Support portal.
  D. Edit the whitelist file in Foundation.
  E. Restart the imaging process in Foundation.
  A. Replace and save whitelist file in Foundation
  C. Download the iso_whitelist.json from the Support portal.
  D. Edit the whitelist file in Foundation.

  ---

  Explanation/Reference:

  When encountering an error related to unsupported ISO media during the imaging process, and the ISO version is not listed in the whitelist file, the consultant should take several steps to resolve the issue. Replacing and saving the whitelist file in Foundation ensures that the latest compatibility data is used. Downloading the iso_whitelist.json from the Support portal provides the most recent and comprehensive list of supported ISO versions. Editing the whitelist file in Foundation allows the consultant to manually add or update entries to include the ISO in question, ensuring the imaging process can proceed.

• Question 75:

  A consultant is preparing to foundation over a customer network that has the following criteria:

  1.

  VLAN segmented network

  2.

  For each node, the consultant has done the following:

  1.

  Connected to the Network Crash Cart of the Node

  2.

  Logged in using "root" credentials

  What should the consultant do next?

  A. 1. CD to /root/nutanix-network-crashcart/ 2. Start Network Utility tool by running: ./network_configuration 3. Change Values
  B. 1. CD to /home/data/nutanix/nutanix-network-crashcart/ 2. Start Network Utility tool by running: ./network_configuration 3. Change Values
  C. 1. Log into CVM using [email protected] 2. CD to /root/Nutanix-network-crashcart/ 3. Start Network Utility tool by running: ./network_configuration 4. Change Values
  D. 1. Log into CVM using [email protected] 2. CD to /home/data/nutanix/nutanix-network-crashcart/ 3. Start Network Utility tool by running: ./network_configuration 4. Change Values
  A. 1. CD to /root/nutanix-network-crashcart/ 2. Start Network Utility tool by running: ./network_configuration 3. Change Values

• Question 76:

  A. Change leaps to https
  B. Change the Directory URL to use an IP rather than a name
  C. Change the plct from 389 to 636
  D. Change the Domain to use an IP rather than a name
  C. Change the plct from 389 to 636

• Question 77:

  While creating an image placement policy on the organizations AOS 5.15-based Nutanix cluster, the administrator wants to ensure there are no restrictions on using the selected images on clusters outside of the identified set.

  What type of Policy Enforcement must the administrator choose?

  A. Soft
  B. Internal
  C. Hard
  D. External
  A. Soft

• Question 78:

  An administrator has two clusters: Site A and Site B.

  Async DR is configured between the clusters as follows:

  1.

  Site A is the Primary Site

  2.

  Site B is the Secondary inactive Site, no VMs running

  3.

  Site A is fully in Production

  4.

  Site B used as Backup/Disaster Recovery

  The customer wants to perform a planned failover between the sites.

  How should the administrator accomplish this?

  A. Click Activate on the Secondary site within the Data Protection Dashboard
  B. Click Activate on the Secondary site and run deactive NCLI command on Primary site
  C. Choose Migrate on the Secondary site within the Data Protection Dashboard
  D. Choose Migrate on the Primary site within the Data Protection Dashboard

• Question 79:

• Question 80:

  While trying to upgrade AOS in a cluster, a consultant receives a warning message that there are two powered-on VMs that need to be powered off for the upgrade to proceed.

  What would cause this warning to be issued?

  A. Upgrading a single-node cluster requires the VMs to be shut down.
  B. Upgrading a two-node cluster requires the VMs to be shut down.
  C. There are not enough resources left in the single-node cluster.
  D. There are not enough resources left in the two-node cluster.
  B. Upgrading a two-node cluster requires the VMs to be shut down.

  ---

  Explanation/Reference:

  The warning message about powering off VMs during an AOS upgrade in a two-node cluster is issued because, in smaller clusters such as two-node configurations, resource availability and redundancy are limited. To safely perform an upgrade without risking service disruption, the VMs need to be powered down to free up resources and ensure that there is sufficient capacity to handle the cluster operations during the upgrade process.References: Nutanix Bible, NCS-Core
