An administrator needs to periodically send information about cluster efficiency via email to a set of users.
What should be configured to accomplish this task?
A. Configure Efficiency widget in Prism Central.
B. Create a new' prism Central project.
C. update Capacity Configurations in Prism Central.
D. Add a schedule to Prism Central reports.
Explanation:
To periodically send information about cluster efficiency via email to a set of users, the administrator can follow these steps:
Create a report in Prism Central that contains the relevant information about cluster efficiency.
Add a schedule to the report to generate and send the report via email to the set of users at a specified frequency.
This will ensure that the users receive regular updates about the cluster efficiency without the need for manual intervention.
How should an administrator correct an SSL error when connecting to a Nutanix cluster?
A. Add the SSL certificate to the workstation’s trusted people store
B. Create a new self-signed certificate for the cluster with a 4096 bit key
C. Create a new SSL certificate for the cluster signed by an AD certificate authority
D. Add the SSL certificate to an AD group policy applied to all computer objects
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.
A node with Erasure Coding fails.
What is the impact?
A. The node stops utilizing Erasure Coding.
B. Potentially increased amount of data stored in the SSD tier.
C. Increased Controller VM CPU Load.
D. AQS unable to do deduplication during the Erasure Coding failure.
Explanation: When a node with Erasure Coding fails, the cluster will automatically rebuild the missing data using replication factor (RF) 2 or 3, depending on the cluster configuration. This means that the data that was previously stored using Erasure Coding will now be stored using full copies, which may increase the amount of data stored in the SSD tier1.
An administrator notices that most of the VMs in the cluster are on one host. Users report that an application seems to respond slowly. The application server VM has significantly more memory assigned to it than other VMs.
How should the administrator fix this issue?
A. Reduce the amount of memory assigned to the VM.
B. Migrate the VM to a different host.
C. Add more memory to the VM.
D. Increase the memory on the CVM.
Explanation: According to the Troubleshoot high memory issues on Azure virtual machines web search result2, one of the common factors in a low memory situation is over-provisioning memory for a VM. Over-provisioning memory can cause memory pressure, which leads to swapping and degraded performance. Therefore, to fix this issue, the administrator should reduce the amount of memory assigned to the VM, based on the average hardware requirements for that operating system and application load.
What is the default network bond setting for an AHV host configuration?
A. active-backup
B. active-active
C. balance-slb
D. balance-tcp
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 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.
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.

A. Destroy a cluster.
B. Upgrade a cluster
C. Migrate a cluster
