The Oracle 1Z0-1123-25 certification exam question is designed for professionals who plan, design, and manage migrations to Oracle Cloud Infrastructure (OCI). Candidates should have a solid understanding of migration assessment methodologies, including workload discovery, dependency mapping, and migration readiness evaluation. The exam also covers OCI core services such as compute, storage, networking, identity management, and security, which are essential for building reliable cloud migration solutions.
Another important topic is migration strategy and execution. Candidates are expected to understand different migration approaches, including rehosting, replatforming, and refactoring. Knowledge of Oracle migration tools, data transfer services, database migration techniques, and disaster recovery planning is critical. The exam may also test your ability to select the most appropriate migration path based on business requirements, cost considerations, and technical constraints.
Security, governance, and operational excellence are also key focus areas. Migration architects must know how to implement security best practices, manage access controls, monitor cloud resources, and optimize workloads after migration. Understanding high availability architectures, backup strategies, and performance optimization techniques will help candidates answer scenario-based questions commonly found in the exam.
Question:
A company wants to migrate its on-premises Oracle Database to Oracle Cloud Infrastructure with minimal downtime and continuous data synchronization during the migration process. Which OCI service or approach is most suitable?
A. Export database backups and restore them manually after shutting down the source database
B. Use Oracle Data Pump only after the migration window begins
C. Use Oracle GoldenGate for real-time replication and synchronization
D. Create a new database manually and import application data later
Correct Answer:
C. Use Oracle GoldenGate for real-time replication and synchronization
Explanation:
Oracle GoldenGate enables near real-time data replication between source and target databases, helping organizations minimize downtime during migrations. This approach supports continuous synchronization until the final cutover, making it a preferred solution for business-critical database migrations to OCI.
