質問 # 51
Which API is NOT available for developing with spatial on ADB?
- A. Java
- B. Python
- C. PL/SQL Gremlin
- D. REST
正解：C
解説：
PL/SQL Gremlin is not an API for developing with spatial on ADB, but rather an API for developing with property graphs on ADB5. Spatial is a feature of ADB that allows developers and analysts to use spatial analysis in every application from basic spatial search and analysis to advanced geospatial applications and Geographic Information Systems (GIS)6. The APIs available for developing with spatial on ADB are REST, Python, Java, and PL/SQL7. Reference:
Oracle Autonomous Database - Oracle Autonomous Database, section "Graph Analytics", subsection "Property Graphs".
Oracle Autonomous Database - Oracle Autonomous Database, section "Spatial".
Oracle Autonomous Database - Oracle Autonomous Database, section "Spatial", subsection "Spatial APIs".

質問 # 53
Which Autonomous Database Service is NOT used to connect to an Autonomous Transaction Processing instance?
- A. HIGH
- B. MEDIUM
- C. TPURGENT
- D. TPPERFORMANT
- E. LOW
正解：D
解説：
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.
