A client's business needs require all of its VMs to reside on the same physical host that is not shared with any other client's resources from the CSP. Which of the following ensures this business…

Moving VMs to a Virtual Private Cloud (VPC) provides network isolation but does not guarantee physical co-location on a single host or exclusive physical isolation from other CSP clients.

Installing a dedicated physical compute host, also known as a dedicated instance or host, provides an exclusive physical server within the cloud provider's data center that is reserved entirely for a single customer. This directly addresses the requirement for all VMs to reside on the same physical host and ensures that the host is not shared with other CSP clients.

While 'dedicate a physical host to the client' is conceptually similar to the correct answer, 'install a dedicated physical compute host' (B) is a more precise and active action that corresponds to specific cloud service offerings providing exclusive physical hardware.

Ensuring all VMs from the client reside on the same physical host does not satisfy the additional requirement that the physical host itself must not be shared with resources belonging to *other clients* from the CSP.
