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.

Data Obfuscation is a feature in Pulse that helps secure a customer's private information by obfuscating the data before it is sent to Nutanix. This ensures that any data sent to Nutanix is not visible to anyone other than the customer, and helps protect sensitive data from unauthorized access or malicious actors.

Nutanix Objects is a storage service that can store petabytes of unstructured data and supports S3 APIs. It is a distributed object store that provides an easy-to-use interface for storing and managing objects and data. It also provides advanced features such as versioning, replication, encryption, and access control.

The Redfish Protocol and Lifecycle Manager (LCM) provide the biggest benefit of allowing BMC and BIOS updates to be done twice as quickly as before. This is because Redfish and LCM allow for updates to be done in parallel, rather than serially, which reduces the amount of time it takes for an update to be completed.

ADS is a feature of Nutanix AHV (Acropolis Hypervisor) that proactively monitors a Nutanix cluster for compute and storage I/O contention or hotspots over a period of time [1]. It provides dynamic and intelligent scheduling of workloads on the cluster for optimal performance and utilization.

The Compatibility and Interoperability Matrix (CIM) is the resource that should be used to ensure a successful upgrade of the hypervisors and AOS within a vSphere-based Nutanix cluster. The CIM provides information about the compatibility and interoperability of the different components of the Nutanix cluster, including the hypervisors, AOS, and other related components.
