NEW QUESTION # 15
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?
- A. Bare Metal instances with total 250 GB of physical memory, anticipating potential spikes in memory demand
- B. Bare Metal instances with total 75 GB of physical memory, considering the actual utilization in physical memory
- C. Bare Metal instances with total 200 GB of physical memory to match the on-premises virtual memory allocation
- D. Bare Metal instances with total 150 GB of physical memory, providing a middle ground that acknowledges the oversubscription in on-premises
Answer: B
Explanation:
Allocating Bare Metal instances with a total physical memory of 75 GB, considering the actual utilization in physical memory, is the most suitable strategy to optimize oversubscription. It aligns with the goal of optimizing resource allocation based on the discovered utilization, ensuring efficient use of resources in the cloud environment.

NEW QUESTION # 36
Which statement accurately describes the routing mechanism within a Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure (OCI)?
- A. VCN local routing necessitates manual configuration of route rules to facilitate infrastructure communication
- B. Each subnet within a VCN employs multiple route rules, allowing for diverse routing paths based on traffic priorities
- C. A subnet in a VCN is associated with a single route table, dictating how outbound traffic from all Virtual Network Interface Cards (VNICs) within that subnet is directed
- D. If no route rule matches the network traffic you intend to route outside the VCN, the traffic is sent to the Internet
Answer: C
Explanation:
In Oracle Cloud Infrastructure (OCI), a subnet in a Virtual Cloud Network (VCN) is indeed associated with a single route table. This route table determines how outbound traffic from all Virtual Network Interface Cards (VNICs) within that subnet is directed, providing a centralized control mechanism for routing within the VCN.
