Explanation
A file is a data type that represents a collection of data stored on a disk or other storage device. A file can have a name, an extension, a size, and other attributes. A file can contain any kind of data, such as text, images, audio, video, etc. A file can be opened, read, written, closed, deleted, or moved by a program. An object is a data type that represents an instance of a class, which is a blueprint for creating objects. An object can have properties, which are variables that store data, and methods, which are functions that perform actions on the object. An object can interact with other objects by sending and receiving messages. An object can inherit properties and methods from its parent class, or override them with its own definitions.

Explanation
= The ONTAP Mediator service and the MetroCluster TieBreaker are two NetApp features that can be used to automate switchover in a MetroCluster IP configuration in the event of a site disaster. The ONTAP Mediator service is a software component that monitors the health and connectivity of the MetroCluster nodes and initiates a switchover when it detects a failure of one site or a network partition between the sites. The MetroCluster TieBreaker is a software component that runs on a third site and acts as a quorum witness for the MetroCluster configuration. The MetroCluster TieBreaker prevents split-brain scenarios and enables automatic switchover when one site becomes unavailable or isolated. References = ONTAP Mediator service overview,
