Which Autonomous Database Service is NOT used to conned to an Autonomous Transaction Processing instance?
- A. TPURGENT
- B. TPPERFORMANT
- C. HIGH
- D. LOW
- E. MEDIUM
Answer: B
Explanation:
Predefined Database Service Names for Autonomous Transaction Processing The tnsnames.ora file provided with the credentials zip file contains five database service names identifiable as tpurgent, tp, high, medium, and low. The predefined service names provide different levels of performance and concurrency for Autonomous Transaction Processing.
* tpurgent: The highest priority application connection service for time critical transaction processing operations. This connection service supports manual parallelism.
* tp: A typical application connection service for transaction processing operations. This connection service does not run with parallelism.
* high: A high priority application connection service for reporting and batch operations. All operations run in parallel and are subject to queuing.
* medium: A typical application connection service for reporting and batch operations. All operations run in parallel and are subject to queuing. Using this service the degree of parallelism is limited to four (4).
* low: A lowest priority application connection service for reporting or batch processing operations. This connection service does not run with parallelism.

NEW QUESTION 70
Which method can be used to migrate on-premises databases to Autonomous Databases in cloud?
- A. Data Pump
- B. RMAN backup & restore
- C. Physical migration method like database cloning
- D. Original Import/Export tools
Answer: A
Explanation:
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, database clones, and transportable tablespaces to move your existing database to ADB.

NEW QUESTION 83
Which two statements are true about the Oracle Cloud Infrastructure (OCI)? (Choose two.)
- A. Regions are dependent on other regions and must be located with 5 thousand kilometers of each other.
- B. Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region.
- C. An OCI region is a localized geographic area, and an availability domain is one or more data centers located within a region.
- D. A single fault domain can be associated with multiple regions and availability domains.
Answer: B,C
Explanation:
A region is a localized geographic area, and an availability domain is one or more data centers located within a region.
Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region.
Oracle Cloud Infrastructure is hosted in regions and availability domains. A region is a localized geographic area. And an availability domain is one or more data centers located within a region. Our region is composed of one or more available domains. Most cloud infrastructure resources are either region-specific, such as virtual cloud networks, or availability-domain-specific, such as compute instance.
Traffic between availability domains and between regions is encrypted. Availability domains are isolated from each other, fault tolerant, and very unlikely to fail simultaneously. Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one domain within a region is unlikely to impact the availability of the others within the same region.

NEW QUESTION 85
While Autonomous Transaction Processing and Autonomous Data Warehouse use the same Oracle database, which statement is true about the workloads?
- A. Data that is bulk loaded, by default, uses the row format in Autonomous Transaction Processing where Autonomous Data Warehouse data format is columnar.
- B. Autonomous Transaction Processing memory usage optimizes workloads for parallel joins and aggregations.
- C. Autonomous Data Warehouse workloads are optimized for mixed workloads.
- D. Autonomous Transaction Processing workloads are optimized for data warehouse, data mart, and data lake.
Answer: A
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
