When the Cassandra and Stargate services fail frequently on a single node, the cluster will automatically put the host in Maintenance Mode to ensure the reliability and performance of the cluster. This will remove the node from the cluster's

IO path and prevent any data loss or corruption.

To maintain high availability in the case of a node failure in a two-node cluster, a Witness VM is required. Therefore, the correct answer is A. The Witness VM acts as a tie-breaker and arbitrator in the event of a split-brain scenario, where both nodes lose connectivity to each other, to ensure that only one node continues to operate and serve workloads. It is also recommended to use a high- performance network to minimize network latency between the two nodes and the Witness VM.

SFTP (Secure File Transfer Protocol) is an option available for an administrator to upload a remote disk file to Image Configuration. SFTP is a secure protocol that ensures that the data being transferred is encrypted and is therefore more secure than other transfer protocols such as FTP or HTTP.

Pulse should only be disabled under the guidance of Nutanix Support and not for any other reason.

Pulse is a feature of the Nutanix cluster that enables the cluster to report back health and performance data to Nutanix for troubleshooting and performance optimization purposes. Disabling Pulse without the guidance of Nutanix Support is not recommended, as it could lead to potential issues with the cluster.
