QUESTION: 65

An administrator is not able to log into Prism Central by using a new Active Directory user account. After Logging with the local user, the administrator verified that Directory Services and Role Mapping setting are valid.

What is the most likely cause of this issue?

Change password at next logon attribute is set.
User does not belong to the Administrators group.
Active Directory functional level of wrong.
Prism Element authentication is not configured.

Answer(s): A

Explanation:

The change password at next logon attribute is a setting that forces a user to change their password when they log on to a domain for the first time or after their password has expired. This attribute is enabled by default for new Active Directory user accounts or when an administrator resets a user's password4.

However, Prism Central does not support this attribute for Active Directory authentication. Users with this attribute enabled will not be able to log on to Prism Central using their Active Directory credentials. They will receive an error message saying "Invalid credentials" or "Authentication failed" when they try to log on5.

Therefore, if an administrator is not able to log on to Prism Central using a new Active Directory user account, the most likely cause of this issue is that the change password at next logon attribute is set for that user account. To resolve this issue, the administrator should disable this attribute for the user account or log on to a domain workstation first and change their password before accessing Prism Central6.

QUESTION: 66

Administrator is creating a Windows 10 VM that will be used for a virtual desktop template. After creating the VM and booting to the ISO, the administrator is unable to install Windows and receives the following error.

What steps does the administrator need to take to install the OS?

Load the Nutanix VirtIO Serial Bus Driver.
Load the VirtIO Network Ethernet Adaper.
Load the Nutanix Virtual Balloon Driver.
Load the Virtual SCSI pass-through controller.

Answer(s): D

Explanation:

Answer(s): D. Load the Virtual SCSI pass-through controller.

The error message shown in the image indicates that Windows 10 setup cannot find any drives to install the OS. This is because the Nutanix AHV hypervisor uses a virtual SCSI pass-through controller to present disks to the VMs, and Windows 10 does not have a built-in driver for this device. Therefore, the administrator needs to load the Nutanix VirtIO driver for the virtual SCSI pass-through controller during the OS installation process. The Nutanix VirtIO driver package contains various drivers that are specifically used by Windows VMs hosted in the Nutanix environment to enhance their stability and performance1. The administrator can download the latest Nutanix VirtIO driver package from the VirtIO downloads page of the Nutanix support portal. The administrator can then follow these steps to load the driver and install the OS2:

On the Windows 10 setup screen, click Load driver.

Insert a USB drive or mount an ISO image that contains the Nutanix VirtIO driver package.

Browse to the location of the driver package and select the folder that matches the OS architecture (32-bit or 64-bit).

Select the vioscsi.inf file and click Next.

Wait for the driver to load and then click Refresh.

Select the disk where you want to install Windows 10 and click Next.

Refer to Exhibit:

After configuring modules for a Remote Syslog Server, the settings are as shown. The administrator notices that even though the level parameter is set to EMERGENCY, that all monitor logs are being sent.

What is the likely cause of this issue?

A second rsyslog server is configured to send all monitor logs.
Having the Module Name set to STARGATE sends all monitor logs regardless of the level.
A Log Level of EMERGENCY includes all monitor logs.
The true setting for Include Monitor Logs sends all monitor logs regardless of the level.

QUESTION: 68

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?

VirtIO drivers have not yet been installed and the disks are IDE disks.
VirtIO drivers have not yet been installed and the disks are SCSI disks.
VirtIO drivers must be installed on AHV for installations of Windows.
VirtIO drivers aren't supported on this version of Windows 2019.

Answer(s): B

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.
