Answer: A

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.

tpurgent: The highest priority application connection service for time critical transaction processing operations. This connection service supports manual parallelism.

A Corporation is building a web application to allow its customers to schedule service requests online. There is also a need to run operational reports at times during non-peak hours. The architecture team is debating whether such reports should be run on the OLTP database or in a separate data mart.

Autonomous Transaction Processing provides all of the performance of the market leading Oracle Database in an environment that is tuned and optimized to meet the demands of a variety of applications, including: mission-critical transaction processing, mixed transactions and analytics, loT, and JSON document store.
As a service Autonomous Transaction Processing does not require database administration. With Autonomous Transaction Processing you do not need to configure or manage any hardware, or install any software. Autonomous Transaction Processing handles creating the database, backing up the database, patching and upgrading the database, and growing or shrinking the database.
