1Z0-1123 Oracle Cloud Infrastructure Migration Architect 2022 Professional Practice Exam
Exam Number: 4826 | Last updated April 19, 2026 | 700+ questions across 4 vendor-aligned objectives
The 1Z0-1123 Oracle Cloud Infrastructure Migration Architect 2022 Professional exam is written for cloud architects and migration specialists who move existing workloads to OCI. Candidates validate the ability to run discovery and assessment, design the target architecture, select the right migration tool, and manage the cutover and post-migration optimization phases.
The heaviest content is Discovery, Assessment, and Planning (roughly 30%), covering application dependency mapping, Oracle Cloud Lift and partner tooling, and sizing. Target Architecture Design contributes another 25% with landing zones, network topology, identity federation, and workload placement patterns.
Migration Execution sits near 25% and drills into Oracle Zero Downtime Migration, Data Pump and Transportable Tablespaces for database migrations, Application Migration strategies, and Object Storage for bulk data transfer. Cutover, Optimization, and Governance rounds out the remaining weight with traffic switchover, cost and performance tuning, and governance via compartments, budgets, and tagging.

10 of 700+ questions
Question #1 - Discovery, Assessment, and Planning
A migration architect at a Fortune 500 firm begins discovery for moving 400 on-prem applications to OCI. She needs dependency maps, right-sizing estimates, and an Oracle-led engagement option for part of the portfolio.
Which combination best fits enterprise-scale discovery with Oracle engagement?
A) Application dependency mapping with partner tooling, plus Oracle Cloud Lift Services for guided migration.
B) Migrating everything lift-and-shift with no assessment.
C) A manual inventory in Excel as the sole plan.
D) Skipping discovery because the team knows the apps.
Show solution
Correct answers: A – Explanation:
Dependency mapping tools and Oracle Cloud Lift Services together cover portfolio discovery with Oracle-led engagement for complex migrations — the intended approach. Option B and Option D are risky. Option C lacks depth for 400 apps. Source: Check Source
Question #2 - Discovery, Assessment, and Planning
A cloud architect is sizing the target OCI environment for a workload that spikes during business hours (60 VMs needed) but idles to 15 VMs overnight. Finance wants optimal cost without compromising performance.
Which OCI capability best addresses the peak-and-trough pattern?
A) Use a single VM with no scaling.
B) Instance pool autoscaling with schedule-based or metric-based scaling.
C) Provision 60 VMs and leave them running 24/7.
D) Manually start and stop VMs each day.
Show solution
Correct answers: B – Explanation:
Instance pool autoscaling scales horizontally based on metrics or schedule — exactly the cost-optimization pattern for variable demand. Option C is wasteful. Option A lacks capacity. Option D is toil. Source: Check Source
Question #3 - Target Architecture Design
An enterprise architect wants an OCI landing zone with multiple compartments separating network, security, shared services, and workload tenants, with IAM baseline policies and a standard VCN design.
Which OCI reference delivers a standardized landing zone?
A) Manual setup without reference architecture.
B) A single flat compartment with no structure.
C) OCI Landing Zone design with compartments, baseline IAM, and reference VCN topology.
D) One VCN per user.
Show solution
Correct answers: C – Explanation:
OCI publishes Landing Zone reference designs with compartment hierarchy, baseline IAM, logging, and network topology — the intended starting point. Option B has no structure. Option D is unmanageable. Option A lacks the guardrails. Source: Check Source
Question #4 - Migration Execution
A DBA migrates a 4 TB Oracle 19c database from on-prem to an OCI VM DB System. The business wants minimal downtime — ideally under one hour.
Which Oracle migration tool best achieves near-zero downtime?
A) Copying the datafiles via FTP during a long maintenance window.
B) A single offline Data Pump export then import.
C) Recreating the schema manually and repopulating data with SQL*Loader.
D) Zero Downtime Migration (ZDM) with logical or physical replication to OCI.
Show solution
Correct answers: D – Explanation:
Zero Downtime Migration orchestrates the move with minimal downtime using logical or physical replication — designed for this scenario. Option B requires a long outage. Option A is even slower. Option C is impractical at 4 TB. Source: Check Source
Question #5 - Migration Execution
A storage team needs to move 200 TB of archival data to OCI Object Storage over a corporate internet link that is saturated during business hours. The move must complete in under two weeks.
Which OCI service fits a 200 TB bulk data move over a saturated link?
A) Object Storage Data Transfer Service (ship physical media to Oracle).
B) Burning the data to DVDs and distributing them.
C) Uploading through a home broadband connection overnight.
D) Compressing to a single zip and emailing it.
Show solution
Correct answers: A – Explanation:
OCI Data Transfer Service ships appliances/disks to Oracle for high-volume bulk loads, bypassing the saturated network — designed for this scale. Options B, C, and D are impractical at 200 TB. Source: Check Source
Question #6 - Target Architecture Design
A network architect needs a hub-and-spoke VCN design: a central shared-services VCN (DNS, Active Directory, monitoring) with three workload VCNs that all route through the hub.
Which OCI construct stitches these VCNs into a hub-and-spoke topology?
A) A single flat VCN with no separation.
B) A Dynamic Routing Gateway with transit routing, peering spokes through the hub.
C) NAT Gateway between all VCNs.
D) A Local Peering Gateway mesh among all VCNs.
Show solution
Correct answers: B – Explanation:
A DRG with transit routing supports hub-and-spoke where spoke VCNs communicate through the hub, enforcing centralized policies. Option D is full mesh, not hub-and-spoke. Option A has no separation. Option C is for outbound internet. Source: Check Source
Question #7 - Migration Execution
A migration lead must move a 2 TB Oracle 12.2 database to Autonomous Database on Shared Infrastructure. Downtime tolerance is 8 hours. Replication is not required.
Which migration path fits?
A) Direct copy of the datafiles to Autonomous Database.
B) Recreate every table manually.
C) Data Pump Export/Import with Object Storage as the staging area for the dump files.
D) Zero Downtime Migration with physical replication.
Show solution
Correct answers: C – Explanation:
For Autonomous Database, Data Pump is the standard migration path, with dumps staged in Object Storage. Option D is overkill for 8-hour downtime. Option A is not supported for Autonomous. Option B is impractical. Source: Check Source
Question #8 - Cutover, Optimization, and Governance
After migrating a workload, the cost lead wants alerting when any compartment’s monthly spend is forecast to exceed its approved budget, with ability to cap spend on a secondary threshold.
Which OCI combination fits?
A) Monthly invoice review only.
B) Shutting down everything on suspicion.
C) A single email sent at end of month.
D) Budgets with forecast alerts and compartment quotas for hard caps.
Show solution
Correct answers: D – Explanation:
Budgets send forecast alerts while compartment quotas enforce hard resource caps — together they deliver the dual-threshold pattern. Option A is lagging. Option C is not actionable. Option B is disruptive. Source: Check Source
Question #9 - Cutover, Optimization, and Governance
A migration program wants to track which workloads came from which business unit across hundreds of OCI resources, and produce per-BU cost reports.
Which OCI feature enables cost allocation by business unit?
A) Defined tags applied to resources with cost analysis grouped by tag.
B) A single tag value for all resources.
C) Manual spreadsheet reconciliation each month.
D) Guessing based on resource names.
Show solution
Correct answers: A – Explanation:
Defined tags (including cost-tracking tags) allow grouping in cost analysis, producing per-BU views — the native feature. Option B defeats the purpose. Option D is unreliable. Option C is lagging. Source: Check Source
Question #10 - Discovery, Assessment, and Planning
A migration consultant needs to pick the right connectivity pattern for a steady, high-throughput link between on-prem data center and OCI — 10 Gbps sustained with predictable latency and SLA.
Which OCI connectivity option fits 10 Gbps sustained, SLA-backed, private connectivity to on-prem?
A) Public internet with no acceleration.
B) Remote Peering Connection only.
C) FastConnect private peering at the required bandwidth.
D) Site-to-Site VPN over the public internet.
Show solution
Correct answers: C – Explanation:
FastConnect provides dedicated, private, SLA-backed connectivity at the required throughput and predictable latency. Option D has higher latency and no SLA for bandwidth. Option A has no guarantees. Option B connects VCNs cross-region, not on-prem. Source: Check Source
