What type of storage would BEST suit a cloud engineer looking to clone the OS from another hypervisor?

1. DAS

2. NAS

3. SAN

4. CAS

The correct answer is: SAN

In the context of cloning an operating system from one hypervisor to another, the most suitable choice is a Storage Area Network (SAN). A SAN is designed specifically for high-speed storage access and supports block storage, which is essential in a virtualization environment. Cloning an OS typically requires the ability to efficiently transfer large amounts of data with low latency, which SAN provides through its network architecture. SANs are optimized for environments that need to handle multiple virtual machines and can facilitate the direct access needed for operations like cloning or migrating VMs. In comparison, Direct Attached Storage (DAS) typically connects directly to a single server or host, making it less versatile for situations involving multiple hypervisors. Network Attached Storage (NAS) is file-based and may not provide the same level of performance required for block-level operations like cloning. Content Addressable Storage (CAS) is specialized storage that focuses on securing and managing unstructured data, which is not particularly suited for the task of cloning an operating system. Thus, a SAN is the best option for a cloud engineer looking to efficiently clone an OS in a virtualized environment.
