20+ practice questions focused on Workload Migration — one of the most tested topics on the Oracle Cloud Infrastructure 2026 Architect Professional (1Z0-997-26) (1Z0-997-26) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Workload Migration PracticeAn architect is planning the migration of a large enterprise application repository stored in an on-premises NFS filer to OCI. The application requires POSIX-compliant shared file storage accessible by multiple compute instances simultaneously across different availability domains. Which OCI storage service should be deployed?
Explanation: OCI File Storage Service (FSS) is the only OCI storage offering that provides POSIX-compliant, NFSv3 shared file systems that can be mounted concurrently by multiple compute instances, including instances in different availability domains within the same region. It is purpose-built for exactly this shared-filer migration scenario. Object and Archive Storage are HTTP-based object stores without POSIX semantics, and Block Volume is single-instance attached storage.
You are migrating a mission-critical multi-tier application from an on-premises data center to OCI. During the migration assessment phase, you identify that the application relies heavily on low-latency network communication (< 1ms round trip time) between the web tier and database tier. Which OCI architectural feature should you implement to satisfy this latency requirement?
Explanation: OCI Compute Placement Groups with the 'Cluster' strategy place instances physically close within a single Availability Domain, minimizing network latency (often sub-millisecond) between them. Deploying the web and database tiers in the same fault domain with a strict locality policy further reduces hops. This is the correct architectural choice for <1ms RTT requirements.
Your company is executing a lift-and-shift migration of 50 physical servers running Red Hat Enterprise Linux (RHEL) to OCI. You want to ensure that the operating systems remain supported, patched, and entitled to Oracle Linux Premier Support without having to rebuild the servers. What conversion utility should you use?
Explanation: The Oracle Linux Upgrade and Conversion tool leverages the `leapp` utility to perform an in-place conversion of RHEL systems to Oracle Linux without rebuilding. It replaces Red Hat subscription packages with Oracle Linux equivalents and reconfigures yum repositories to point to Oracle's public yum servers, thereby granting access to Oracle Linux Premier Support. This is the only option that directly addresses OS-level conversion and entitlement for RHEL-to-Oracle Linux migrations on OCI.
Your team is executing a cutover plan for migrating a production Microsoft SQL Server database from an on-premises environment to OCI Compute running Windows Server. To ensure data integrity, you decide to use Always On Availability Groups with the on-premises primary and the OCI replica. After completing the initial seed and syncing the databases, you perform the failover. However, application servers in OCI cannot connect to the new primary database. What is the most likely root cause?
Explanation: After a successful Always On Availability Group failover, the new primary replica listens on TCP port 1433 (default SQL Server port) and on the Availability Group listener port (default 1433 or a custom port). If application servers in OCI cannot connect, the most likely cause is that OCI VCN Security Lists or Network Security Groups are blocking traffic on those ports between the application subnet and the database subnet. Unlike on-premises environments where firewall rules may already be open, OCI's virtual cloud network enforces default-deny ingress, so explicit rules are required to allow SQL traffic.
During a database migration assessment from an on-premises Oracle Database (version 11.2.0.4) to OCI Base Database Service running Oracle Database 19c, you discover that the legacy database uses deprecated initialization parameters and character sets that are incompatible with 19c. How should you address this migration blocker?
Explanation: Oracle's supported upgrade path from 11.2.0.4 to 19c requires running the Pre-Upgrade Information Tool (utlu19i.sql) to identify deprecated parameters, invalid objects, and character set issues, remediating them, upgrading the binaries, and then migrating via Data Pump or RMAN transportable techniques. This addresses the blocker at its root rather than trying to bypass version incompatibilities.

Practice all Workload Migration questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Workload Migration. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Workload Migration questions on the 1Z0-997-26 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Workload Migration is tested as part of the Oracle Cloud Infrastructure 2026 Architect Professional (1Z0-997-26) (1Z0-997-26) blueprint. Practicing with targeted Workload Migration questions ensures you can handle any format or difficulty that appears.
