Nutanix NCP-MCI-6.5 Exam With Confidence Using Practice Dumps

Automated live migration is a feature of Nutanix that allows the cluster to automatically move VMs from one host to another without any downtime, in order to optimize the performance and availability of the cluster. According to the Nutanix documentation1, automated live migration can occur in the following scenarios:

• Cluster resource hotspot: When a host or a group of hosts experience high resource utilization, such as CPU, memory, or network, the cluster can automatically migrate some VMs to other hosts with lower utilization, in order to balance the load and avoid performance degradation.
• AOS upgrade: When upgrading the Nutanix software (AOS), the cluster can automatically migrate the VMs from the host that is being upgraded to another host in the same availability zone, in order to maintain the VM availability and minimize the impact of the upgrade process.
• AHV host maintenance mode: When putting an AHV host into maintenance mode, the cluster can automatically migrate all the VMs from that host to another host in the same availability zone, in order to prepare the host for maintenance operations such as hardware replacement or firmware update.

One node hosts two VMs while the node being upgraded is in maintenance mode. This is because Nutanix supports a feature called Rolling Upgrade that allows upgrading AHV on a cluster without any downtime or impact to the VMs. The Rolling Upgrade feature performs the upgrade one node at a time, by putting the node in maintenance mode, evacuating the VMs to other nodes, upgrading AHV, and then bringing the node back online. The VM-VM anti-affinity policy ensures that the four VMs are not placed on the same node during the evacuation process, so one node will host two VMs temporarily while the other node is being upgraded.

The task that needs to be performed when time is not synchronizing properly after deploying a cluster is NTP configuration. In the Nutanix Multicloud Infrastructure (NCP-MCI) 6.5, Network Time Protocol (NTP) is used to synchronize the system time across all the nodes in a cluster. If the time is not synchronizing properly, it indicates that there might be an issue with the NTP configuration. Therefore, checking and correcting the NTP configuration would be the appropriate action to resolve this issue. The other options like DNS configuration, HA configuration, and SMTP configuration are not directly related to time synchronization in a cluster.
