An administrator is using Nutanix Move to migrate a Windows VM from ESXi to AHV. Automated guest preparation is failing with an error:
Account has UAC enabled error
The administrator is using the local built-in administrator account for the Windows VM Admin approval mode must remain enabled.
What should the administrator do to continue with the migration with Nutanix Move?


A. Use a Domain Admin account for the Windows VM


B. Reboot the Windows VM and try the migration again


C. Follow manual VM preparation guidelines


D. Place Windows VM in Maintenance Mode

  Follow manual VM preparation guidelines

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?


A. Connect to same switch as the cluster and ping.


B. Install Java on the Foundation VM.


C. Enable IPv6 and multicast on the switch.


D. Enable IPv6 and multicast on the laptop.





C.
  Enable IPv6 and multicast on the switch.

Explanation: 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.

Where in the Support Portal can it be determined if a version of AOS is supported on a particular hardware platform.


A. Solution Documentation


B. Upgrade Paths


C. Hardware Compatibility Lists


D. Compatibility and Interoperability Matrix





D.
  Compatibility and Interoperability Matrix

Explanation: To determine if a version of Acropolis Operating System (AOS) is supported on a specific hardware platform, the "Compatibility and Interoperability Matrix" section of the Nutanix Support Portal should be consulted. This resource provides detailed information on supported hardware for different AOS versions, ensuring that all components are compatible and supported for optimal operation.

B. Leap


C. Metro Availability


D. Asyn&DR





D.

D. · External USB drive . Access to Nutanix FTP . Encrypted key required for accessing clusters





B.
  · A trial license activation code for Prism Starter . Creating an account for access to Nutanix Support Portal . Guide for dark site deployments using Nutanix standards

An administrator receives a notification that storage in a Nutanix cluster is unavailable. The cluster consists of five nodes and is configured with a Fault-Tolerance level of 1 (FT-1).
Upon investigation, the administrator finds the following:

• All AHV hosts are powered on and the CVMs are running
• Nodes A, B, and C are connected to one top of rack switch
• Nodes D and E are connected to a second top of rack switch
• The cluster status command run on Node A shows that CVM services on nodes D and E are down

Which issue is causing the storage outage?


A. The default gateway for the CVMs and AHV hosts is down.


B. The switch connecting Nodes D and E is down.


C. The genesis process is down on both Nodes D and E.


D. Nodes D and E are in maintenance mode.





B.
  The switch connecting Nodes D and E is down.

Based on customer requirements, a consultant conducted an AHV cluster deployment. Each node is configured with four NICs.
Which two components should the consultant manually update in the As-Built Guide? (Choose two.)


A. Node Port Layout Diagram


B. Network Cabling Diagram


C. Logical Design Diagram


D. Site installation Diagram





A.
  Node Port Layout Diagram

B.
  Network Cabling Diagram

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.

A customer is considering increasing the Redundancy Factor from 2 to 3 for a Nutanix cluster in their existing environment. Which option would provide the company with the optimal solution?


A. Four Compute Nodes with 25% available disk space


B. Six Compute Nodes with 25% available disk space


C. Three Compute Nodes with 40% available disk space


D. Five Compute Nodes with 40% available disk space





B.
  Six Compute Nodes with 25% available disk space

Explanation: To increase the Redundancy Factor (RF) from 2 to 3, at least five nodes are required for the cluster to function correctly with RF3, as each data block needs to be replicated to three different nodes. However, the optimal solution that offers both the necessary node count and sufficient storage overhead is:
Six Compute Nodes with 25% available disk space: This configuration ensures that there are enough nodes to support RF3 while maintaining adequate storage capacity for redundancy without overutilization.

An administrator is currently using both 10g uplink with LACP and balance-tcp. A single VM should not be allowed to use more than a single 10G uplink, and both uplinks should be utilized. Which two command should be used to configure the bond? (choose two)


A. Ovs-vsctl set port br0-up bond_mode=balance-slb


B. Ovs-vsctl set port br0-up bond_mode=balance-tcp


C. Ovs-vsctl set port br0-up bond_mode=active-backup


D. Ovs-vsctl set port br0-up other_config: bond-rebalance-interval=30000





A.
  Ovs-vsctl set port br0-up bond_mode=balance-slb

D.
  Ovs-vsctl set port br0-up other_config: bond-rebalance-interval=30000
