NCP-MCI-6.5 Exam Dumps - Nutanix Certified Professional (NCP) Questions and Answers

According to the web search results, the most efficient action an administrator should take to ensure a supported state when adding a node with a higher AOS release to an existing cluster is to perform a standalone reimage of the new node and then add it to the cluster1. This way, the new node will have the same AOS version as the existing nodes, and there will be no compatibility issues or downtime. Therefore, option C is correct, while options A, B, and D are not.

The issue described pertains to the inability to ping the IPMI IPs after moving the IPMI network links to the actual switches with specific VLAN configurations. The two changes that the administrator needs to make are:

A. SSH to AHV and set the VLAN ID using IPMI Tool: Since all VLANs are tagged in the new network configuration, the IPMI network interface needs to be aware of the VLAN it’s supposed to communicate on. This can be achieved by setting the VLAN ID using the IPMI Tool on the AHV.

C. SSH to AHV and change the IP address using IPMI tool: If the IPMI IP addresses were initially set in a different subnet that is not routable in the new network configuration, the administrator would need to change the IPMI IP addresses to match the new network configuration. This can be done by SSHing to the AHV and using the IPMI Tool to change the IP address.

According to the Nutanix Support & Insights, in a two-node ROBO cluster with a witness VM, if one node goes down, the other node sends a leadership request to the witness VM and goes into single-node mode. The cluster remains available and can tolerate another failure of either the witness VM or the network link.

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.

According to the web search results, Distributed Storage Fabric (DSF) is the scale-out storage technology that makes HCI and cloud possible45. DSF pools the storage devices that are directly attached to a cluster of servers and presents them to applications across a variety of storage protocols4. DSF also manages and protects data by a fine-grained, distributed metadata system that ensures uniform distribution of data throughout the cluster to eliminate hot spots and speed up rebuilds

The best way to fix this issue is to increase the amount of memory assigned to the VM from the Prism web console. This option allows the administrator to modify the VM configuration without accessing the CVM or shutting down the VM. The Prism web console provides a simple and intuitive interface for managing Nutanix clusters and VMs1. To change the memory allocation for a VM, the administrator can follow these steps2:

• Go to the VM dashboard
• Select the VM from the VMs list
• Choose Update
• Adjust the amount of memory assigned to the VM
• Click Save
