What tool in vSphere is used to manage and schedule VM snapshots?

The VMware vSphere Web Client is the correct choice for managing and scheduling VM snapshots because it provides a user-friendly graphical interface that allows administrators to easily create, manage, and delete snapshots for virtual machines. This tool streamlines the process by allowing users to view the VM's snapshot hierarchy, take new snapshots, revert to previous snapshots, and tag snapshots with descriptions.

In addition, the vSphere Web Client simplifies the management of snapshot settings and schedules, facilitating automation through built-in features that can be customized to meet specific operational needs. This ease of use and comprehensive functionality makes the vSphere Web Client the preferred method for handling VM snapshots within a vSphere infrastructure.

While the other tools mentioned have their own purposes, they do not specifically focus on the management and scheduling aspects of VM snapshots in the same manner. The vSphere Command-Line Interface can manage snapshots, but it requires command-line expertise and is less intuitive for users who prefer a graphical interface. The vCenter Server Appliance is a management platform that hosts the vSphere environment but does not provide direct tools for snapshot management itself. The VMware ESXi Shell is primarily used for system-level tasks on individual ESXi hosts and lacks the comprehensive snapshot scheduling capabilities found in the vSphere Web Client.
