An administrator is performing validation testing of a new-deploy cluster. During this test, the administrator disconnect each LAN interface from each of the nodes while pinging the hypervisor and guest VMs.
When the first interface is disconnected, pings continue as expected to the hypervisor, but pings stop responding from the guest. Pings continue when the interface is reconnected. When the second interface is disconnected, pings continue to both the hypervisor and guest VMs.
What could be the cause of this error?
A. This is normal behavior for a LAN Failover
B. Switch ports are configured with different VLANs
C. Portfast is not enabled on the switch ports
D. One of the network interfaces has a bad patch cable.
Explanation: switch ports are configured with different VLANs could be the cause of this error. If the switch ports are not configured with the same VLANs as the network interfaces on each node, then there could be a mismatch in network connectivity when one interface is disconnected1. This could affect the guest VMs that are using a different VLAN than the hypervisor.
While installing Windows 2019 on a new VM on an AHV cluster, an administrator notices there aren’t any drives listed for the install.
What might the problem be?
A. VirtIO drivers have not yet been installed and the disks are IDE disks.
B. VirtIO drivers have not yet been installed and the disks are SCSI disks.
C. VirtIO drivers must be installed on AHV for installations of Windows.
D. VirtIO drivers aren’t supported on this version of Windows 2019.
Explanation:
VirtIO drivers are device drivers that are specifically designed for virtualized environments. They allow the guest operating system to communicate directly with the underlying hardware, bypassing the emulation layer. This improves the performance and efficiency of the virtual machines. VirtIO drivers are supported by various hypervisors, including Nutanix AHV1.
Nutanix AHV uses SCSI disks for VMs by default. However, Windows does not have native support for SCSI disks and requires VirtIO drivers to recognize them. Therefore, if an administrator is installing Windows 2019 on a new VM on an AHV cluster, they need to install the VirtIO drivers before selecting the destination disk for the installation. Otherwise, they will not see any drives listed for the install2.
To install the VirtIO drivers during Windows installation, the administrator can use one of the following methods3:
Use a VirtIO ISO image that contains the driver files. The administrator can download the VirtIO ISO image from the Nutanix support portal and upload it to the AHV image service. Then, they can attach the VirtIO ISO image to the VM as a CD-ROM device and load the driver from it during Windows installation.
Use a Nutanix Guest Tools (NGT) ISO image that contains the driver files and other tools. The administrator can download the NGT ISO image from Prism Element or Prism Central and attach it to the VM as a CD-ROM device. Then, they can load the driver from it during Windows installation.
Use a floppy disk image that contains only the driver files. The administrator can create a floppy disk image using tools such as WinImage or WinRAR and upload it to the AHV image service. Then, they can attach the floppy disk image to the VM as a floppy device and load the driver from it during Windows installation.
The administrator wants a container to be displayed and limited to 1TB in the hypervisor.
What advanced container setting must the administrator set?
A. Advertised Capacity
B. Reserved Capacity
C. Advertised Quota
D. Reserved Quota
An administrator has set up a local web server accessible to the Nutanix clusters.
Which two steps are required to set up LCM for an environment without Internet access? (Choose two.)
A. Download the lcai_disconnecced_version. tar.gz LCM bundle from the support portal.
B. Edit LCM Advanced Settings in Prism Element and enter the address of the web server.
C. Edit LCM Advanced Settings m Prism Central and enter the address of the web server.
D. Download the lcm_dark_site_version. tar . gz LCM bundle from the support portal.
What is the expected operation during node addition when the new node has a different AOS version?
A. The entire cluster is upgraded to the latest one-click release.
B. The node is added and a separate upgrade operation must be performed.
C. The addition fails and forces the administrator to image using standalone Foundation.
D. The node is automatically re-imaged using the software currently running in the cluster.
Explanation: The node is automatically re-imaged using the software currently running in the cluster. This is because Nutanix supports a feature called Auto Re-Image that allows adding nodes with different AOS versions to an existing cluster without manual intervention. The Auto Re-Image feature detects the AOS version mismatch and automatically downloads and installs the same AOS version as the cluster on the new node. This ensures that the cluster remains in a consistent state and avoids any compatibility issues.
An Administrator is working on a one-node ROBO cluster configurations
Which statement is true for this configuration?
A. Witness vm required to break cluster quoram
B. Supported hardware is NX-1175-G5 and G6
C. witness vm should be 8vcp and 20gb ram
D. the minimum RPO 8 hours required
