The Recycle Bin is a feature that allows administrators to recover data that has been accidentally deleted from the cluster, by storing deleted files in a temporary holding area for a certain period of time. During this time, the deleted files can be restored to their original location, effectively undoing the deletion.

The default retention period for the Recycle Bin is 24 hours, which means that any files that are deleted from the cluster will be retained in the Recycle Bin for a period of 24 hours before they are permanently deleted. This retention period can be customized to suit the needs of a particular environment, but the default value is 24 hours.

Prism Element is the management interface for Nutanix clusters and it can be accessed through the IP address of any CVM (Controller Virtual Machine) in the cluster. The CVM is a virtual machine that runs on each Nutanix node and is responsible for managing the storage and compute resources of the node. Each CVM has a unique IP address, and any of these IP addresses can be used to directly access Prism Element.

Accessing Prism Element through the IP address of a CVM allows the administrator to manage the cluster, including configuring storage, creating and managing virtual machines, and monitoring the health of the cluster.

It's important to note that Prism Central is a separate application and it doesn't have the same functions as Prism Element, it's mainly used for multi-cluster management.

To configure Replication Factor 1 (RF1), the cluster must have at least three nodes. In RF1, data is replicated to two other nodes within the cluster, so having at least three nodes is necessary to ensure that the data is replicated. Moreover, when you configure RF1, the cluster must have a minimum of three nodes to ensure that the data is accessible even if one of the nodes goes down.

In order to resolve the issue of not receiving NCC health checks and alerts for newly-added nodes via email, the administrator should configure SMTP (Simple Mail Transfer Protocol) settings. SMTP is used to send email notifications from the Nutanix cluster, and if it is not configured properly, the health checks and alerts will not be sent via email. The administrator should check the SMTP settings in the Prism web console and ensure that they are correct and that the correct email address is specified for receiving notifications. This will ensure that the health checks and alerts for the newly-added nodes are sent to the correct recipient.

Erasure coding is a data efficiency mechanism in Nutanix that replaces the traditional replication factor for suitable data. Erasure coding uses a technique known as "forward error correction" to spread data across multiple drives in a cluster, such that if some drives fail, the data can still be reconstructed. This allows for a much higher storage density and a more efficient use of disk space as compared to traditional replication, where multiple copies of the same data are stored across multiple drives. Deduplication and Compression are also data efficiency mechanisms in Nutanix which help to reduce the storage overhead by eliminating the redundant data. Intelligent Cloning is a Nutanix feature which helps to create multiple instant, space-efficient clones of a VM.

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.
