Which two block storage protocols are supported on vSphere?

In the context of vSphere, block storage protocols that are supported include iSCSI and Fibre Channel SAN (Storage Area Network). The SAN protocol is primarily used in environments pursuing optimal performance and storage management capabilities. It provides a way to connect servers to storage devices over a dedicated network, allowing for high-speed data transfer and providing features such as multipathing and storage clustering.

While block storage protocols are essential for various storage solutions, other choices provided refer to file storage protocols or different versions of NFS (Network File System), which do not fall under the block storage category. Understanding the distinction between block storage, like SAN, and file storage protocols is crucial for effectively managing and designing a vSphere environment.
