An administrator has been alerted to a VM that has high I/O latency and wants to determine if there are any other factors, such as insufficient network or memory resources that correlate, as part of a troubleshooting process.
Which type of chart should the administrator create to allow all relevant data to be easily exported to CSV for later analysis?
A. A VM entity chart with each of the relevant metrics.
B. A cluster metric chart for each of the relevant metrics
C. A cluster entity chart with each of the relevant metrics
D. A VM metric chart for each of the relevant metrics
An administrator needs to provide access for a user to view real-time performance metric for all VMs on all clusters across the datacenter.
Which method accomplishes this with the least effort and ongoing maintenance?
A. Configure IDP authentication and assign the user to the Cluster Admin role in Prism Central.
B. Configure AD authentication and assign the user to the Viewer role in Prism Element.
C. Configure AD authentication create a custom role, assign the user to the role, and apply the role to all clusters and VMs
Explanation:
The best method to provide access for a user to view real-time performance metrics for all VMs on all clusters across the datacenter is to configure AD authentication create a custom role, assign the user to the role, and apply the role to all clusters and VMs. This method accomplishes this with the least effort and ongoing maintenance because:
AD authentication allows Nutanix Prism Central to integrate with an existing Active Directory (AD) domain and use AD users and groups for authentication and authorization5. This simplifies user management and avoids creating local users on Prism Central.
Creating a custom role allows Nutanix Prism Central to define granular permissions for different actions and entities based on specific needs6. This ensures that users only have access to what they need and nothing more.
Assigning the user to the custom role allows Nutanix Prism Central to grant access rights for that user based on the role definition7. This avoids assigning permissions individually for each user.
Applying the role to all clusters and VMs allows Nutanix Prism Central to propagate the access rights for that role across all entities in scope8. This ensures that users can view real-time performance metrics for all VMs on all clusters without having to configure each entity separately.

Which three cluster operations require an administrator to reclaim licenses?(Choose three)
A. Destroy a cluster.
B. Upgrade a cluster
C. Migrate a cluster
D. Remove a Node from a cluster
E. Move Nodes between clusters.
Upon logging into Prism Central, an administrator notices high cluster latency.
How can the administrator analyze data with the least number of steps or actions?
A. Modify Data Density in the main Prism Central dashboard.
B. Click on the chart in the widget to expand the data elements.
C. Take note of the duster name and create a new Analysis chart.
D. Click the cluster name in the cluster quick access widget.
Explanation: According to the Nutanix Prism Central Guide, you can click on any chart in a widget to expand it and view more details about the data elements.
An administrator logs into the Nutanix Support Portal and notices there is a new version of the LCM Framework available. In an effort ensure LCM is providing the latest features, the administrator would like to upgrade LCM.
How can the LCM Framework be upgraded?
A. Perform an LCM inventory
B. Upload the latest LCM Framework as an image in the image Configuration in Prism
C. Upload the latest LCM Framework bundle via Upgrade Software in Prism
D. Upgrade AOS
Explanation:
LCM (Life Cycle Manager) is a feature that allows Nutanix administrators to perform one-click firmware and software upgrades for Nutanix clusters and components. LCM fetches inventory and update information from a pre-configured URL that contains the latest versions of firmware and software packages. However, upgrading Nutanix AOS does not automatically update the fetch URL. To update the fetch URL, the administrator needs to update the LCM framework. The LCM framework is the core component of LCM that provides the logic and functionality for inventory, download, and upgrade operations1.
To upgrade the LCM framework, the administrator needs to perform an LCM inventory. An LCM inventory is a process that scans the cluster and its components for their current firmware and software versions and compares them with the available versions from the fetch URL. If there is a newer version of the LCM framework available, it will be shown as an update option under Cluster Software Component in the Available Updates page. The administrator can then select and apply the LCM framework update to upgrade it to the latest version2.
The administrator can perform an LCM inventory using Prism Element or Prism Central. The steps are as follows3:
In Prism Element, go to the Network Configuration page and click Life Cycle Management.
In Prism Central, go to the Services page and click Life Cycle Management.
Click Inventory in the toolbar and select Perform Inventory from the drop-down menu.
Wait for the inventory process to complete and check for any available updates.

An administrator needs to configure Prism to send encrypted messages to a set of recipients.
Which setting must be applied?
A. Use SMTP Port 25
B. Configure Prism Central to use Cluster Lockdown
C. Install SSL certificates on Prism Central
D. Set SMTP Security Mode to STARTTLS
Explanation: The best way for the administrator to configure Prism to send encrypted messages to a set of recipients is to set the SMTP Security Mode to STARTTLS. This will ensure that all messages sent over SMTP are encrypted and secure. Additionally, the administrator should consider installing SSL certificates on Prism Central to ensure that the messages are being sent securely. Finally, the administrator should consider configuring Prism Central to use Cluster Lockdown, which will help ensure that the messages are only sent to the intended recipients.
An administrator has been notified by a user that a Microsoft SQL Server instance is not performing well.
When reviewing the utilization metrics, the following concerns are noted:
Memory consumption has been above 95% for several months
Memory consumption has been spiking to 100% for the last five days
Storage latency is 2ms.
When logging into Prism Central, how could the administrator quickly verify if this VM has performance bottlenecks?
A. See Capacity Runway.
B. Filter VM by Efficiency.
C. Update Capacity Configurations.
D. Perform Entity Sync
In a default configuration of an AHV cluster, a single node fails.
What happens to the running VMs on that node?
A. The cluster restarts all VMs in the event of a host failure
B. The VMs do a live migration to the master node in the cluster
C. The VMs do a live migration to any other node in the cluster
D. The cluster attempts to restart VMs on other hosts
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.
An administrator is troubleshooting vDisk performance issues in a Nutanix cluster with hybrid disks. The VMs all have Flash Mode enabled.
But users are reporting disk latency.
What could cause the performance issues?
A. Flash mode is disabled when a node fails.
B. Compression is disabled on the vDisk storage container.
C. The VMs vDisks are in multiple containers.
D. Data size for flash mode exceeds 25% of the SSD capacity.
Explanation: data size for flash mode exceeds 25% of the SSD capacity could cause the performance issues. Flash mode is a feature that allows vDisks to be pinned to SSDs for faster access, but it has a limit of 25% of the SSD capacity per node. If this limit is exceeded, some vDisks may be evicted from flash mode and cause disk latency2.
