It covers the key drivers behind cloud adoption, the benefits of moving to Oracle Cloud Infrastructure (OCI), and the challenges businesses may face during migration. Candidates will gain insights into the different migration strategies and methodologies used to ensure seamless transitions from on-premises environments to the cloud.

Topic 2

Migrate Oracle Databases to OCI Database Services: This section tests the knowledge of Database Migration Specialists in planning and executing successful database migrations to OCI. It covers database migration strategies, different OCI database services, and the available methods for transferring databases to the cloud. Candidates will learn how to analyze existing database workloads and select the most efficient migration approach for maintaining data integrity and performance.

Topic 3

Design and Implement Migrations Using Oracle Cloud VMware Solution (OCVS):This section measures the skills of VMware Cloud Engineers in migrating on-premises VMware environments to OCI. It covers source discovery to assess existing infrastructure, designing the target OCVS environment, and understanding migration prerequisites. Candidates will also explore Hybrid Cloud Extension as a tool for seamless migration and integration between VMware workloads and OCI.

Topic 4

Design and Implement Migrations Using Oracle Cloud Migrations Service: This section assesses the abilities of Cloud Migration Specialists in designing and implementing cloud migrations using Oracle Cloud Migrations Service. It includes planning, inventory management, and assessment tasks required for successful migrations. Candidates will learn how to replicate and execute migration tasks, including the process of migrating AWS EC2 instances to OCI. The goal is to ensure minimal downtime and efficient resource allocation during the transition.

Topic 5

Migrate Containerized Applications to OCI: This section evaluates the expertise of Cloud DevOps Engineers in migrating containerized applications to Oracle Cloud Infrastructure. It introduces the fundamentals of OCI Container Engine for Kubernetes and Oracle Cloud Infrastructure Registry. Candidates will learn the key phases involved in migrating containerized workloads and ensuring proper orchestration and scaling within the OCI ecosystem.

Oracle Cloud Infrastructure 2025 Migration Architect Professional Sample Questions (Q49-Q54):

NEW QUESTION # 49
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?

A. The replication plugin does not support encrypted VM disk files
B. The OCI tenancy has exceeded its service limit for compute instances, preventing the replication plugin from provisioning necessary resources
C. The source VMs are using an unsupported file system that the replication plugin is unable to process
D. The VDDK (Virtual Disk Development Kit) file required by the replication plugin is missing in the OCI Object Storage

Answer: D

Explanation:
The VDDK file is essential for the replication plugin to access and replicate VM disk files. If this file is missing in the OCI Object Storage, the replication plugin will be unable to function properly, resulting in an inactive status.

NEW QUESTION # 50
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. 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
C. If no route rule matches the network traffic you intend to route outside the VCN, the traffic is sent to the Internet
D. Each subnet within a VCN employs multiple route rules, allowing for diverse routing paths based on traffic priorities

Answer: B

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.

NEW QUESTION # 51
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 150 GB of physical memory, providing a middle ground that acknowledges the oversubscription in on-premises
D. Bare Metal instances with total 200 GB of physical memory to match the on-premises virtual memory allocation

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 # 52
As a migrations architect, you are explaining the workflow of Oracle Cloud Migrations (OCM) service to a business partner. After the replication of virtual machine (VM) data to Oracle Cloud Infrastructure (OCI) using OCM, what is the next step to launch the migrated instance?

A. Create a Compute instance with an attached Block Volume and configure the Hydration Agent to transfer the replicated data into the Block Volume
B. A Compute instance is automatically launched after the replication process
C. Deploy a Resource Manager Stack to launch the Compute instance with the replicated Block Volume

Answer: C

Explanation:
Deploying a Resource Manager Stack to launch the Compute instance with the replicated Block Volume is the correct next step after the replication of VM data to OCI using OCM.

NEW QUESTION # 53
You plan to use Oracle Zero Downtime Migration to perform offline 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?

A. OCI Golden Gate
B. Data Guard
C. Unplug and Plug Database
D. Data Pump
E. Remote Cloning

Answer: B,C,D

Explanation:
Data Pump, Unplug and Plug Database, and Data Guard are all valid migration methods provided by Oracle Zero Downtime Migration, which allows for the migration of Oracle databases with minimal downtime.
