vSAN (VMware vSphere Storage Appliance) is typically used as primary storage in VMware environments, particularly in situations where hyper-converged infrastructure is desired. Among the options you provided, vSAN is used as mandatory, primary storage in: A. VMware Cloud on AWS VMware Cloud on AWS leverages vSAN to provide software-defined storage as part of its infrastructure services. It's an example of how vSAN can be utilized for primary storage in a cloud environment that's an extension of the on-premises VMware environment. The other options (B, C, and D) do not typically use vSAN as mandatory primary storage in the same way that VMware Cloud on AWS does. These options are more focused on different aspects of VMware technologies and may use other storage solutions depending on specific requirements.

A. VMware Cloud on AWS often uses vSAN as part of its infrastructure. B. VMware Horizon is a virtual desktop infrastructure (VDI) solution that can benefit from vSAN storage for its virtual desktops. C. VMware Aria Automation is not a widely recognized VMware product, and there's no specific information available about its storage requirements. D. Tanzu Kubernetes Grid Integrated Edition (formerly known as Pivotal Container Service or PKS) is primarily focused on Kubernetes orchestration and container management, and while it can integrate with vSphere, it doesn't typically use vSAN as mandatory primary storage.

VSAN, NSX, vSphere is mandatory for VMC environment

A is correct

In the VMware ecosystem, vSAN storage is used as mandatory, primary storage in environments like: B. VMware Horizon VMware Horizon is a virtual desktop infrastructure (VDI) solution, and vSAN is often used as the primary storage solution for VDI deployments to provide the necessary performance and scalability for virtual desktops. While vSAN can be used in various other environments, it's commonly used in VDI deployments due to its ability to deliver high-performance, scalable, and cost-effective storage for virtual desktops.
