Free Oracle Cloud Infrastructure 2025 Migration Architect Professional Exam 1Z0-1123-25 Exam Practice Test

Which option best describes the term Inventory Asset in the context of Oracle Cloud Migrations (OCM) service?

• Virtual Machines that have been specifically selected to migrate to OCI within the OCM UI
• The entire on-premises environment that is subject to discovery and analysis by OCM
• Virtual Machines that have been automatically discovered and listed in the OCM UI
• An OCI Compute instance representing the migrated on-premises asset in the OCM UI

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?

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

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?

• Trigger the replica
• No action required. By default, the replica is available as a block volume
• Activate the replica
• Initialize the replica

As part of your organization's initiative to migrate on-premises workloads to Oracle Cloud Infrastructure using Oracle Cloud Migrations (OCM) service, you have been tasked to understand the end-to-end migration workflow. Which sequence correctly represents the stages in the OCM migration workflow?

• Discovery, Assessment and Planning, Inventory, Execution, Replication
• Assessment and Planning, Replication, Discovery, Inventory, Execution
• Discovery, Inventory, Assessment and Planning, Replication, Execution
• Assessment and Planning, Discovery, Inventory, Replication, Execution

You plan to use Oracle Zero Downtime Migration to perform ofline or online migration of Oracle databases, where the migration method type may be Physical or Logical. Which three migration methods does Oracle Zero Downtime Migration provide?

• Remote Cloning
• OCI Golden Gate
• Data Pump
• Data Guard
• Unplug and Plug Database

As a migration architect, you are tasked with transferring objects across buckets within the same region and to buckets in different regions. Which feature of Oracle Cloud Infrastructure (OCI) Object Storage should you utilize to accomplish this data migration?

• Object Transition
• Object Copy
• Object Move
• Object Mirroring

A cluster of physical servers running in an on-premises data center is configured with a total of 100 GB physical memory. The total virtual memory allocated across all the VMs running on this cluster is 200 GB. Which term describes the virtual-to-physical memory allocation ratio for this cluster?

• Thick provisioning
• Encapsulation
• Oversubscription
• Overprovisioning

You plan to perform migrations between on-premises and OCI. What is the minimum bandwidth required with FastConnect as the dedicated network link between the environments?

• 10 Gbps
• 50 Gbps
• 100 Gbps
• 1 Gbps

Your company is planning to decommission their on-premises data center hosting a set of Virtual Machines (VMs) that heavily rely on VMware technologies. The goal is to migrate those VMs into OCI, make this transition as quick as possible, ensuring the environment is highly available and can be controlled by the company after the migration. What are the two advantages of using Oracle Cloud VMware Solution (OCVS)?

• The company can bring their own product licenses (BYOL) for VMware products such as vSphere, vSAN, and NSX
• The company can move those application VMs into OCVS "as-is"
• The company can control root access to the OCVS environment
• The company can free up their IT team as Oracle takes over the management, including updates and patching of the OCVS environment
• The company could convert all of VMware-based applications into native OCI Compute instances

Your company is looking to migrate its IT infrastructure into Oracle Cloud VMware Solution (OCVS). The source infrastructure includes a variety of workloads, such as a few business-critical VMs that require continuous availability, and a large set of non-critical dev-test VMs. As a migration cloud architect, you are exploring Hybrid Cloud Extension (HCX) migration methods to identify the best approaches for each type of workload. Which HCX migration method would be the most appropriate to use in order to migrate both business-critical VMs and dev-test VMs?

• HCX Bulk Migration for migrating business-critical VMs and HCX vMotion for non-critical dev-test VMs
• HCX vMotion for migrating business-critical VMs, and Cold Migrations for non-critical dev-test VMs
• Cold Migration for migrating both business-critical and non-critical dev-test VMs
• HCX Bulk Migration for migrating the business-critical VMs, and Cold Migrations for non-critical dev-test VMs
