NEW QUESTION 5
Your customer has upgraded their on premise 11.2 database to 12.2. During this migration the database was migrated to a pluggable database and is now in production.
How should the customer unplug their database to migrate to Autonomous Database (ADB)?

• A. Pluggable databases cannot be migrated to ADB using plug, unplug or clone.
• B. Create a database link from source database to the ADB environment and clone the PDB.
• C. Unplug to an xml file so database files and xml file can be uploaded to object storage.
• D. Unplug into a pdb archive which can be uploaded to object storage.

Answer: A

Explanation:
Since an ADB database has some restrictions on the object types and Oracle Database Options you need to use a logical migration method rather than a physical one.
The main migration tool for migrating to ADB is Data Pump. You can export your schemas and import them into ADB using Data Pump. To sync up the additional/incremental changes on the source database during the export/import process you can use GoldenGate or GoldenGate Cloud Service to replicate those changes to ADB.
In the current release you cannot use physical migration methods like backup/restore, Data Guard, Pluggable/Unplug , database clones, and transportable tablespaces to move your existing database to ADB.

NEW QUESTION 18
While Autonomous Transaction Processing and Autonomous Data Warehouse use the same Oracle database, which statement is true about the workloads?

• A. Autonomous Transaction Processing memory usage optimizes workloads for parallel joins and aggregations.
• B. Autonomous Data Warehouse workloads are optimized for mixed workloads.
• C. Autonomous Transaction Processing workloads are optimized for data warehouse, data mart, and data lake.
• D. Data that is bulk loaded, by default, uses the row format in Autonomous Transaction Processing where Autonomous Data Warehouse data format is columnar.

Answer: D

Explanation:
- Both ADW and ATP share the Autonomous Database platform of Oracle Database on Exadata Cloud infrastructure.
The difference is how the services have been optimized within the database. When you start loading data into the autonomous database, we store the data in the appropriate format for the workload.
* If it is ADW, then we store data in columnar format because that's the best format for analytics processing.
• If it is ATP, then we store the data in row format because that's the best format for fast single row lookups.
- Oracle Autonomous Database is offered in two workload-optimized flavors
* Autonomous Data Warehouse (ADW), which has been optimized for analytic workloads
• Autonomous Transaction Processing (ATP). ATP is optimized for transaction processing or mixed workload https://docs.oracle.com/en/cloud/paas/atp-cloud/atpug/autonomous-intro-atp.html#GUID-B90147B2-EA04-414 https://docs.oracle.com/en/cloud/paas/atp-cloud/atpug/autonomous-intro-atp.html#GUID-B90147B2-EA04-414
