Oracle 1Z0-1094-23 Exam Questions
- Topic 1: Oracle Migration and Integration: This topic describes Management and Integration of Oracle Data. It also focuses on Migration Use Cases and Solutions.
- Topic 2: Migrating to Cloud Database Services using RMAN, Data Pump, and Cloning: This topic focuses on using Recovery Manager (RMAN) to migrate to OCI. It also describes when to use Unplug/Plug, Remote Cloning, and Relocation of PDBs to migrate to OCI. Additionally, it delves into usage of Data Pump to migrate to Oracle Database to Oracle Cloud Infrastructure (OCI).
- Topic 3: Migrating to Cloud Database Services using SQL Developer, Cloud Backup, and GoldenGate: There are multiple sub-topics of this exam topic including using GoldenGate to facilitate Oracle database migrations to the Oracle Cloud Infrastructure (OCI), assessing and choosing migration strategies based on source database and environments, leveraging Oracle Database Cloud Backup for migrations, moving databases from third party clouds, and performing migrations with SQL Developer.
- Topic 4: Source and Target Database Options: The topic includes explanation of the source databases and target options available in the Oracle Cloud Infrastructure. Moreover, it has sub-topics related to assessing major migration evaluation considerations such as potential downtime, network constraints, data constraints such as and database configuration factors including version, database size and encryption, block size, time zone settings, release update level, edition, options, and target database specifications.
- Topic 5: Migrating to Cloud Database Services using Oracle Zero Downtime Migration (ZDM): It delves into Zero Downtime Migration solution of Oracle. It also focuses on preparation to use ZDM including service nodes, backups, source and target databases, network and encryption factors. Furthermore, this topic discusses management of database migration workflows with ZDM through options, executing migrations, commands, and troubleshooting common issues that arise.
- Topic 6: Data Integration: It focuses on explanation of ETL vs. ELT data integration architectures. It delves into analysis of components to transfer data from on-premises databases to Oracle cloud databases. Moreover, it focuses on implementation of change data capture with GoldenGate for real-time data movement, performing data quality checks during mappings, extracting data from SaaS applications into Oracle warehouses, and handling data joining from hybrid sources like databases and files prior to loading target systems.
- Topic 7: Migrating to Autonomous Database: The focal point of this topic is discussing when to leverage Oracle Data Pump for migrations as well as using ZDM solution to transfer on-premises databases onto Autonomous Databases.
- Topic 8:

Note: Premium Questions for 1Z0-1094-23 were last updated On 03-09-2024 (see below)
In Zero Downtime Migration, which port number is used by the source and target system to access Object Storage?
Port 443 is used by both the source and target systems to access Object Storage during Zero Downtime Migration. This port is commonly associated with secure HTTPS traffic, ensuring encrypted and secure communication with cloud storage services.
How can you properly pause a Zero Downtime Migration (ZDM) job?
To pause a ZDM job, you can use the -pauseafter option with the zdmcli migrate database command to specify a migration phase where the process should be paused. Alternatively, the zdmcli suspend job command with the job ID can pause the migration at any point, providing flexibility in managing the migration process.
In which two ways can you use Data Pump to move data to the cloud? (Choose two.)
Data Pump can move data to the cloud by importing from a dump file stored in Oracle Cloud Infrastructure (OCI) Object Storage or directly from an Oracle Database using a database link. These methods allow for efficient data transfer to the cloud, with the dump file method providing a way to stage data in OCI Object Storage and the database link method enabling direct data transfer between databases.
What four best practices should you follow with Oracle Data Pump when migrating an Oracle Database to the Oracle Cloud? (Choose four.)
Best practices for using Oracle Data Pump for database migration to Oracle Cloud include performing schema-level exports to focus on specific schemas, using multiple dump files with wildcards for parallelism and efficiency, avoiding the use of SYS as SYSDBA to maintain security and stability, and utilizing parameter files for export and import commands to manage complex options and improve repeatability and reliability of Data Pump operations.
Which two migration methodologies can you use for migrating on-premises databases to Autonomous Database with Oracle Zero Downtime Migration (ZDM)? (Choose all correct answers)
When migrating on-premises databases to Autonomous Database using Oracle Zero Downtime Migration (ZDM), both Physical Online and Logical Online migration methodologies can be employed. Physical Online migration involves replicating the physical database files to the cloud with minimal downtime, while Logical Online migration uses logical structures like SQL to migrate data, allowing for transformations and optimizations during the migration process. Both methods aim to minimize downtime and ensure continuous availability of the database services during the migration.
