1In cloud migration strategy, which of the 6 Rs describes moving an application to OCI compute as-is, without changing its code or architecture?
A.Refactor
B.Rehost
C.Repurchase
D.Retire
Explanation: Rehost (often called lift-and-shift) moves a workload to the cloud with no changes to its code or architecture, typically onto equivalent compute instances. It is the fastest of the 6 Rs and is the basis for most VM-based OCI migrations.
2An application is rewritten to replace its self-managed Oracle Database with OCI Autonomous Database while keeping most application code on compute. Which migration strategy does this best represent?
A.Rehost
B.Replatform
C.Retain
D.Repurchase
Explanation: Replatform (lift-tinker-and-shift) keeps the core application largely intact but swaps one or more components for managed cloud services, such as moving a self-managed database to Autonomous Database. It captures cloud benefits without a full rewrite.
3During the discovery phase of a migration project, what is the primary goal?
A.To delete unused workloads immediately
B.To build an inventory of applications, dependencies and resource usage
C.To purchase OCI capacity before any assessment
D.To rewrite all applications as microservices
Explanation: Discovery builds a comprehensive inventory of the existing estate, including applications, servers, dependencies and resource utilization. This inventory feeds the assessment and planning phases so the right migration strategy and waves can be chosen.
4Why are workloads commonly grouped into migration waves rather than migrated all at once?
A.To migrate dependent applications together and reduce risk
B.Because OCI only allows one VM per tenancy
C.To avoid using the Oracle Cloud Migrations service
D.Because waves are required for billing
Explanation: Wave planning groups interdependent applications so they move together, limiting blast radius and allowing lessons from early waves to improve later ones. Starting with low-risk workloads builds confidence before tackling complex, tightly coupled systems.
5A legacy application runs on hardware that is being decommissioned, has no business owner and no active users. Which migration disposition is most appropriate?
A.Rehost
B.Refactor
C.Retire
D.Replatform
Explanation: Retire is the correct disposition for workloads that provide no business value and have no users or owner. Identifying and retiring such applications during assessment reduces migration scope, effort and ongoing cost.
6When building a business case for migrating to OCI, what does a total cost of ownership (TCO) analysis primarily compare?
A.Only the monthly OCI compute price
B.The full cost of running on-premises versus on OCI, including hardware, power, staffing and licensing
C.The number of VMs that can be migrated per day
D.The color scheme of the OCI Console
Explanation: A TCO analysis compares the complete cost of the current environment, including hardware refresh, data center power and cooling, staffing and software licensing, against the projected cost on OCI. This shows the financial impact of migration beyond the headline cloud compute price.
7A tightly coupled monolithic application is being broken into microservices and re-architected to use OCI managed services during migration. Which of the 6 Rs is this?
A.Rehost
B.Repurchase
C.Refactor
D.Retain
Explanation: Refactor (re-architect) involves significantly changing the application's design, such as decomposing a monolith into microservices and adopting cloud-native managed services. It delivers the most cloud benefit but requires the most effort and code change.
8Which factor most often forces a workload to be classified as 'retain' (keep on-premises for now) during migration assessment?
A.A regulatory or technical constraint that prevents moving it yet
B.A preference for blue console themes
C.The workload uses Linux
D.The workload has more than one CPU
Explanation: Retain is chosen when a workload cannot move yet, often due to regulatory, data-residency, latency or technical dependency constraints, or because it is approaching end-of-life. The workload stays on-premises and is reassessed later.
9Which sequence best represents a typical phased cloud migration methodology?
A.Migrate, discover, plan, assess
B.Discover and assess, plan and design, migrate, validate and optimize
C.Validate, retire, discover, build
D.Optimize, migrate, discover, plan
Explanation: A sound migration methodology moves from discovery and assessment of the estate, to planning and target design, to executing the migration, and finally validating and optimizing the workloads in the cloud. Each phase informs the next.
10An organization wants to abandon its on-premises CRM and adopt a SaaS CRM product instead of migrating the existing system. Which migration strategy is this?
A.Repurchase
B.Rehost
C.Replatform
D.Refactor
Explanation: Repurchase means replacing the existing application with a different product, most commonly moving to a SaaS offering. The old application is retired and users move to the new commercial service rather than migrating the original codebase.

About the OCI Migration Architect Pro Exam

The Oracle Cloud Infrastructure 2025 Migration Architect Professional certification (1Z0-1123-25) validates the skills needed to plan and execute workload migrations to Oracle Cloud Infrastructure. It targets migration architects and assumes hands-on OCI experience. The exam covers cloud migration fundamentals and strategy (the 6 Rs, discovery and assessment), OCI networking for migrations, the Oracle Cloud Migrations service for replicating and migrating source VMs including AWS EC2 and VMware workloads, the Oracle Cloud VMware Solution with VMware HCX, container migration to OKE using OCIR, moving infrastructure workloads between OCI regions, and migrating Oracle databases using OCI Database Migration and Zero Downtime Migration. Oracle states the questions test applied, hands-on knowledge rather than memorisation, so candidates should combine the official learning path with practical work in an OCI tenancy.

Assessment

50 multiple-choice questions spanning seven topic areas: cloud migration fundamentals (10%), OCI networking (5%), Oracle Cloud Migrations service (25%), Oracle Cloud VMware Solution (15%), container migration (10%), cross-region migration (15%) and Oracle database migration (20%).

Time Limit

90 minutes for 50 questions, about 1.8 minutes per question.

Passing Score

68 percent. Oracle determines passing scores statistically and may adjust them; the result is reported as pass or fail with section-level feedback.

Exam Fee

USD $245 (prices vary by country and currency); the exam is booked through Oracle University and delivered by Pearson VUE. (Oracle Corporation (Oracle University, delivered through Pearson VUE))

OCI Migration Architect Pro Study Tips from Top Performers

1Build a free or trial OCI tenancy and actually run a migration with the Oracle Cloud Migrations service so the discovery, replication and launch steps become muscle memory rather than theory.
2Memorise the 6 Rs and be able to map a described workload to the right one; many fundamentals questions hinge on choosing rehost versus replatform versus refactor.
3Know when to use FastConnect versus Site-to-Site VPN: FastConnect for predictable high bandwidth and lower latency, VPN for quick or lower-volume connectivity over the internet.
4For databases, be clear on the difference between OCI Database Migration, Zero Downtime Migration, Data Pump and RMAN, and which give near-zero downtime through logical replication or Data Guard.
5Understand VMware HCX migration types (bulk, replication-assisted vMotion and live vMotion) and when each is appropriate for OCVS migrations.
6For cross-region moves, practise using custom images, Object Storage and Block Volume cross-region replication, and Resource Manager so you can rebuild a stack idempotently in the target region.
