問題 #50
You are setting up replication in the Oracle Cloud Infrastructure (OCI) File Storage service. What is a key requirement for the target file system?

A. It must be located in a different region than the source file system
B. It must be located in the same availability domain as the source file system
C. Only a file system that has been exported can be used as a target file system
D. It must not have been previously exported

答案：D

解題說明：
The target file system must not have been previously exported in order to be used for replication. This ensures that the target file system is clean and ready to receive replicated data without any existing configurations.

問題 #51
You have set up cross-region replication for a block volume in the US West (Phoenix) region, choosing US West (San Jose) as the destination. Now, you want to create a new volume from the volume replica in the US West (San Jose) region. What should you do?

A. No action required. By default, the replica is available as a block volume
B. Trigger the replica
C. Initialize the replica
D. Activate the replica

答案：D

解題說明：
Activating the replica is the correct action to take in order to make the volume replica usable as a block volume in the US West (San Jose) region. This step ensures that the replica is ready for use and can be attached to instances for storage purposes.

問題 #52
Your company wants to expand its cloud infrastructure footprint by adopting Oracle Cloud VMware Solution (OCVS). The OCVS Software Defined Data Center (SDDC) platform will be dedicated to hosting business-critical workloads and should avoid single points of failure within its architecture. Which two would be considered while setting up the solution?

A. vSphere Distributed Resource Scheduler (DRS)
B. vSAN Fault Domain
C. OCI Fault Domain
D. HCX Mobility Groups

答案：B,C

解題說明：
OCI Fault Domains and vSAN Fault Domains are critical considerations to avoid single points of failure and ensure high availability for business-critical workloads hosted on the OCVS SDDC platform.

問題 #53
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 150 GB of physical memory, providing a middle ground that acknowledges the oversubscription in on-premises
B. Bare Metal instances with total 200 GB of physical memory to match the on-premises virtual memory allocation
C. Bare Metal instances with total 75 GB of physical memory, considering the actual utilization in physical memory
D. Bare Metal instances with total 250 GB of physical memory, anticipating potential spikes in memory demand

答案：C

解題說明：
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.

問題 #54
Which two statements are true about physical migration of Oracle databases?

A. During physical migration, copies of database objects are created in dumps
B. Source and Target database versions must be the same
C. You cannot filter and migrate database objects
D. You cannot achieve zero or near-zero downtime with physical migration
E. You can run a cloud premigration advisor tool to perform compatibility check prior to migration

答案：B,E

解題說明：
Running the cloud premigration advisor tool is a recommended practice before migration to perform a compatibility check and identify any potential issues. Also, for physical migration, the source and target database versions must be the same to ensure compatibility.

問題 #55
