After configuring Active Directory as the desired authentication service, an administrator is not able to login into Prism Central using privileged account.
Which configuration must be checked first?
A. Account lock status
B. Role Mapping
C. Local user account
D. Cluster Lockdown
Explanation: According to the Nutanix Community1, users can authenticate using their Active Directory credentials when Active Directory support is enabled for Prism Central. To enable Active Directory support, you need to configure Role Mapping12, which defines how Active Directory groups map to Prism Central roles.
Refer to Exhibit:
An administrator wants to replace and old node with a node of newer generation in a 3-
node cluster. The administrator has already chosen the appropriate node. But unable to
remove it from the cluster.
Why is the Remove Host option not shown in the exhibit?
A. The host needs to be placed into maintenance Mode before.
B. It is only possible to remove a host from a cluster using CLI.
C. It is not possible to remove a node from a the cluster using Prism Central
D. It is not possible to remove a host from a 3-node cluster.
Explanation: A Nutanix cluster requires a minimum of three nodes to maintain quorum and data availability. Removing a node from a 3-node cluster would violate the redundancy factor and cause data loss. Therefore, it is not possible to remove a host from a 3-node cluster using Prism or CLI. The only way to replace a node in a 3-node cluster is to use the Foundation tool, which will erase the existing cluster configuration and create a new cluster with the new node1.
An administrator needs to deploy an application with a large amount of data connected via Nutanix volumes. Which two actions should the administrator take when designing the Volume Group? (Choose two.)
A. Distribute workload across multiple virtual disks
B. Enable RSS (Receive Side Scaling)
C. Use multiple subnets for iSCSI traffic
D. Enable thick provisioning on the Volume Group(s)
Explanation: According to the Nutanix Volumes - Recommendations And Best Practices
web search result3, two actions that the administrator should take when designing the
Volume Group are:
Distribute workload across multiple virtual disks: Use multiple disks rather than a
single large disk for an application. Consider using a minimum of one disk per
Nutanix node to distribute the workload across all nodes in a cluster. Multiple disks
per Nutanix node may also improve an application’s performance. For
performance-intensive environments, we recommend using between four and
eight disks per CVM for a given workload.
Enable RSS (Receive Side Scaling): Receive-side scaling (RSS) allows the
system to use multiple CPUs for network activity. With RSS enabled, multiple CPU
cores process network traffic, preventing a single CPU core from becoming a
bottleneck. Enabling RSS within hosts can be beneficial for heavy iSCSI
workloads. For VMs running in ESXi environments, RSS requires VMXNET3
VNICs. For Hyper-V environments, enable VMQ to take full advantage of Virtual RSS.
What is the proper sequence to perform a one-click upgrade to a Nutanix cluster? Item instructions: For each procedure, indicate the order in which that procedure must take place to meet the item requirements. Not all procedures are valid. Identify any invalid procedures using the drop-down option.
Refer to Exhibit:
Why has an anomaly been triggered?
A. Because the CPU usage crossed the blue band.
B. Because the blue band range increased over the last 2 days
C. Because the CPU usage dropped belon' 20%
D. Because the CPU usage reached 100%
Explanation: Nutanix leverages a method for determining the bands called ‘Generalized
Extreme Studentized Deviate Test’. A simple way to think about this is similar to a
confidence interval where the values are between the lower and upper limits established by
the algorithm.
Another web source3 shows an example of how anomaly detection works in Nutanix Prism Central. In the video, you can see that when the observed value of a metric deviates
significantly from the predicted value based on historical data, an anomaly event is
triggered and displayed on a chart.
Therefore, by comparing the observed values with the predicted values based on historical
data, Nutanix anomaly detection can identify abnormal behavior and alert you accordingly.
An administrator needs to relocate an AHV cluster to a new datacenter during a maintenance window. The cluster will use the same IPs in the new datacenter.
Which two steps should be taken to prepare for this task? (Choose two.)
A. Reconfigure IPMI for the new datacenter
B. Shut down all user VMs in the cluster
C. Relocate the linked LDAP server
D. Stop all Nutanix Files clusters
Explanation:
According to the web search results, two steps that should be taken to prepare for relocating an AHV cluster to a new datacenter during a maintenance window are:
Shut down all user VMs in the cluster: This step is necessary to ensure that there is no data loss or corruption during the relocation process. The user VMs can be shut down either individually or in bulk by using the Prism Element web console or the acli command-line interface1.
Stop all Nutanix Files clusters: If the AHV cluster hosts any Nutanix Files clusters, they should be stopped before relocating the cluster. Nutanix Files clusters are composed of one or more virtual machines that provide file services to clients. Stopping a Nutanix Files cluster will stop all the file server VMs and release the resources they consume2. The Nutanix Files clusters can be stopped by using the Prism Element web console or the ncli command-line interface3.
