In a VMware Cloud Foundation (VCF) environment, when adding a new cluster to an existing VI workload domain, the new cluster must use the same principal storage as the existing cluster. Since the existing cluster is using NFS, the available storage options for the new cluster would be NFS or vSAN, depending on the configuration.

Aria Automation (formerly vRealize Automation) is designed to automate the deployment of applications and infrastructure across hybrid cloud environments. It enables the provisioning, management, and orchestration of IT services, helping organizations streamline their service delivery.

VM Snapshots capture the VM's state (disk and memory) for easy rollback. Replication (A) copies VMs to a remote site, Storage vMotion (C) migrates the VM's disk to another datastore, and Encryption (D) secures data but isn't used for rollback.

Aria Operations for Logs (formerly known as vRealize Log Insight) is used to collect, analyze, and troubleshoot logs from various components within VMware Cloud Foundation, including the vSAN cluster. It provides detailed insights into the logs, allowing administrators to perform in-depth troubleshooting of issues like degraded health statuses.

When creating a new Content Library, you first need to specify a name and description to define the library's purpose.
For a Local Content Library, you need to choose the datastore where the library contents will be stored.
This is essential for proper organization and accessibility of content.
To create and manage content libraries, you must navigate to the Content Libraries section in the vSphere Client.
