NEW QUESTION 30
What is the primary purpose of deploying a Remote Agent Appliance in an on-premises environment when using the Oracle Cloud Migrations (OCM) service?

To perform real-time data compression and deduplication of the source data to be transferred to OCI

To serve as a temporary storage buffer to cache data before it is transferred to OCI

To facilitate direct VPN connectivity between the on-premises data center and OCI

To discover on-premises workloads and provide detailed inventory information to OCI

NEW QUESTION 31
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

NEW QUESTION 32
A team of migration cloud architects are evaluating different storage options for deploying virtual machines (VMs) in Oracle Cloud VMware Solution (OCVS). They are comparing VMware vSAN and OCI Block Storage to determine the best fit for their needs. Which two statements accurately reflect the usage of vSAN and OCI Block Storage in OCVS?

OCI Block Storage inherently provides better IOPS performance than vSAN for all workload types

OCI Block Storage can be scaled up or down independently of compute resources, unlike vSAN which scales with the cluster

vSAN requires an external network connectivity to synchronize data across hosts, whereas OCI Block Storage does not

vSAN is tightly integrated with VMware’s SDDC ecosystem, thus allowing for storage policies to be directly applied to VMs, whereas OCI Block Storage operates as independent block volumes

OCI Block Storage can utilize VMware-specific storage policies for VM provisioning and management, just like vSAN in the OCVS environment

NEW QUESTION 33
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

NEW QUESTION 34
Which Hybrid Cloud Extension (HCX) migration type is designed for large-scale migration of workloads that cannot afford downtime?

HCX vMotion

HCX OS Assisted Replication

HCX Replication Assisted vMotion

HCX Bulk Migration

NEW QUESTION 35
Which three transfer mediums does the OCI Database Migration service use to perform the initial load of the databases?

Data Pump via File Storage

Data Pump via Object Storage

Data Pump via network link

Data Guard via replication

Data Pump dump upload via OCI CLI

NEW QUESTION 36
You are planning to migrate an Oracle database from an on-premises data center to OCI Database service. Which two can be used for the migration?

Data Transfer Service

Data Pump

Block Volume Replication

Zero Downtime Migration

Oracle Cloud Migrations

NEW QUESTION 37
You are setting up Oracle Cloud Migrations (OCM) service for migrating workloads to Oracle Cloud Infrastructure (OCI). As part of the initial configuration, a Source Environment is created with Remote connection agents and Agent Dependency. However, the Replication plugin indicates the status as Inactive. What is the likely reason for this issue?

The replication plugin does not support encrypted VM disk files

The OCI tenancy has exceeded its service limit for compute instances, preventing the replication plugin from provisioning necessary resources

The source VMs are using an unsupported file system that the replication plugin is unable to process

The VDDK (Virtual Disk Development Kit) file required by the replication plugin is missing in the OCI Object Storage

NEW QUESTION 38
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
