2021 Sep 1Z0-569 sample question

Q21. Which prerequisite task is necessary before adding an administrator? 

A. Add authorizations to a role 

B. Add a role 

C. List administrators 

D. List authorizations associated with a role 

Answer: B 


Q22. What is the main difference between a multi-datasource and an Active GridLink datasource? 

A. There is no difference. They are just different terms referring to the same construct and capability. 

B. An Active GridLink datasource is able to respond to FAN events to provide Fast Connection Failover (FCF), Runtime Connection Load-Balancing (RCLB), and RAC instance graceful shutdown. 

C. An Active GridLink datasource is designed specifically for Exadata and cannot be used with any other RAC database. 

D. A multi-datasource is meant to work only with non-Oracle high-availability datasources. 

Answer: B

 (FAN) With Active GridLink, WebLogic subscribes to the database's Fast Application Notification (FAN) events using Oracle Notification Services (ONS). This allows the 

WebLogic connection pool to make more informedruntime load-balancing decisionbased on the current workload of each RAC node. By sending database calls to the node with lowest current workload, the average latency of user request/response times is reduced. 


 (FCF) Additionally, Active GridLink uses Fast Connection Failover (FCF), which also uses the notification events, to enable rapid database failure detection for greater applicationresilience. This feature also eases the system management overhead by allowing 

WebLogic to automatically reconfigure its connection pool, in the event of planned additions or removals of RAC nodes. 

Note: A new technology component has been added to WebLogic Server onExalogiccalled 'Active 

GridLink for RAC (Real Application Clusters)'. Active GridLink for RAC provides optimized 

WebLogic-to-Oracle RAC database connectivity by interfacing WebLogic Server directly with the Oracle RAC protocols. This new technology supersedes the existing WebLogic Server capability commonly referred to as 'Multi-Data-Sources'. Active GridLink for RAC provides more intelligent load-balancing across RAC nodes based on the current workload of each RAC node, faster connection failover if a RAC node fails and more transparent RAC node location management. Active GridLink is also able to handles global transactions more optimally, where multiple individual database operations have been encapsulated into a single atomic transaction, by the enterprise Java application. The net effect is, for enterprise Java applications involving intensive database work, applications achieve a higher level of availability with better throughput with reduced and more consistent response times. In addition to the performance benefits, Active GridLink for RAC (figure 3), also simplifies the configuration of Data Sources in WebLogic Server, reducing the number of configuration artifacts required for Oracle RAC connectivity and mostly eliminating RAC Service configuration changes from having a corresponding change in WebLogic Server.
