How would an administrator upgrade the LCM framework to the latest version?
Answer(s): B
To upgrade the LCM framework to the latest version, the administrator must go to the Settings page of the Prism Central UI, and then select the Upgrade Software option. This will show the available versions of the LCM framework, and allow the administrator to select the desired version and upgrade.

A single host in a four-node AHV-based cluster experiences a complete network failure. If more than enough resources exist in the cluster to tolerate a node failure, what happens to the user VMs running on that host?
In the case of a single host in a four-node AHV-based cluster experiencing a complete network failure, the user VMs running on that host will stay up, but will be unreachable until connectivity is restored. This is because if more than enough resources exist in the cluster to tolerate a node failure, the VMs will continue to run, but will be unable to communicate with other nodes in the cluster due to the network failure. This is stated in the official Nutanix Certified Associate (NCA) v6.5 study guide on page 49, under the heading "Virtual Machine Availability in the Event of Node Failure".
A SQL Server cluster has been deployed on an AHV cluster. To ensure maximum uptime, the administrator wants the SQL Server VMs running on different hosts while leveraging High Availability in case of host failure.Which configuration would meet these requirements?
Answer(s): C
Anti-affinity rules are used to ensure that virtual machines are not running on the same physical host. This can be useful in situations where the administrator wants to ensure that virtual machines are running on different hosts for high availability and to minimize the impact of a host failure. By creating an anti-affinity rule via CLI, the administrator can ensure that the SQL Server VMs are running on different hosts while still leveraging high availability in case of host failure.

In an AHV five-node cluster, an SSD fails within a node that has two SSDs and four HDDs installed.What will happen to the cluster environment?
Answer(s): D
When an SSD fails within a node, the CVM on that node will reboot to maintain the health of the cluster. The CVM is responsible for managing the storage and virtualization components of the cluster, and a reboot is necessary to ensure that the cluster continues to function properly. The VMs running on that host will not be affected and continue to run, but the CVM will be unavailable for a short period of time until the reboot is completed. The Cluster continues to operate in a healthy state and doesn't go in read-only mode or cause any host to go down.
