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 If there is a newer version of the LCM framework available, it will be shown as an update option under Cluster Software Component in the Available Updates page.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.
An administrator needs to boot a VM to a bootable CD. The administrator tries to configure the VM to boot to it, select to add disk, and goes to the images available. The image for the bootable CD is unavailable.
What is the Likely issue?
A. The CD-ROM interface is too slow.
B. The administrator selected a disk attached before it can boot to a CD.
C. The VM needs to have a standard disk attached before it can boot to a CD.
D. The bootable CD image is corrupted during creation.
An Administrator has been asked to deploy VMs using a specific image. The image has been configured with settings and applications that will be used by engineering to develop a new product by the company.
The image is not available on the desired cluster, but it is available in other cluster associated with Prism Central.
Why isno’t the image available?
A. The image bandwidth policy has prevented the image upload.
B. The cluster should be removed from all categories.
C. The cluster has not been added to the correct category
D. The image placement policy was configured with enforcement.
An administrator needs to ensure logs, alerts and information is consistent across clusters that are located in different countries.
Which service needs to be configured?
A. SMTP
B. DNS
C. SNMP
D. NTP
Explanation: NTP service needs to be configured to ensure logs, alerts and information is consistent across clusters that are located in different countries. NTP stands for Network Time Protocol and it is used to synchronize the clocks of all the nodes in a cluster1. This helps to maintain accurate timestamps for logs, alerts and other information that are generated by Nutanix clusters1.
An administrator recently added new SSDs to a Nutanix cluster and knows the firmware will be out of date, Due to security constraints, the cluster does not have access to the Internet.
Which two steps must be completed to update the firmware? (Choose two.)
A. Download the disk firmware from the OEM's website.
B. Download a darksite bundle and deploy an internal webserver,
C. Select Upgrade Software, then upload the firmware bundle.
D. update the LCM Source and URL to access the firmware bundle.
How will an HDD failure affect VMs with data on the failed device?
A. The VMs will crash, and will be restarted once the failed HDD has been replaced and the data has been restored.
B. A live migration will be initiated, moving the affected VMs to a host that contains the replica data.
C. The VMs will remain operational on that host and continue to function normally with no noticeable impact
D. An HA event will occur, causing the affected VMs to restart on a node that contains the replica data.
Explanation: According to the Troubleshooting hosted disk I/O performance problems (1008885), when using VMware hosted products, consider that both the virtual machines and host operating system often share the same disk resources and hardware. If a hard disk fails, the virtual machines that have data on the failed device will experience an HA event, causing them to restart on a node that contains the replica data.
A VM in a 12-node Nutanix cluster is hosting an application that has specific Physical GPU requirements. Only three nodes in the cluster meet this requirement.
The administrator wants to allow a general workload to be distributed across all nodes in the cluster and must make sure that the node hosting the VM meets its requirements.
How should the administrator perform this task?
A. Create a sperate three-node cluster using the nodes that meet the requirement.
B. Configure VM-Host affinity for the nodes that meet the application's GPU requirement.
C. Over-Provision the application VM with additional virtual GPUs.
D. Configure anti-affinity rules between the application VM and the other VMs running on the cluster.
Explanation: Configure VM-Host affinity for the nodes that meet the application’s GPU requirement. This is because VM-Host affinity allows the administrator to specify which nodes a VM can run on or must not run on1. By creating a VM-Host affinity rule that binds the application VM to the three nodes that have the physical GPU, the administrator can ensure that the VM will always run on a node that meets its requirement, regardless of any HA or migration events. This also allows the other nodes in the cluster to host other VMs without any restrictions.
