Questions 6

As an OCI architect, you are designing a cloud environment to accommodate an on-premises Data Center workload, which currently has a memory oversubscription ratio of 2:1. The ratio means the total physical memory of the on-premises servers is 100 GB, and the virtual memory allocated is 200 GB. Upon source discovery, you discovered the actual physical memory utilization is below 50%. Which memory allocation strategy should you consider for the Bare Metal instances in OCI to optimize oversubscription, applying the actual utilization?

Options:

A.

Bare Metal instances with total 150 GB of physical memory, providing a middle ground that acknowledges the oversubscription in on-premises

B.

Bare Metal instances with total 250 GB of physical memory, anticipating potential spikes in memory demand

C.

Bare Metal instances with total 75 GB of physical memory, considering the actual utilization in physical memory

D.

Bare Metal instances with total 200 GB of physical memory to match the on-premises virtual memory allocation
