Oracle Database Administration 2019 Certified Professional — Question 79

A Java application using thick JDBC connections will soon be deployed, and you must configure a RAC database to support highly available connections.
Broken connections must be re-established as quickly as possible.
Which feature will support this requirement?

Answer options

• A. Transparent Application Failover (TAF) using Fast Application Notification (FAN)
• B. Transparent Application Failover (TAF)
• C. Fast Connection Failover (FCF)
• D. Fast Connection Failover (FCF) with Transparent Application Failover (TAF)

Correct answer: C

Explanation

The correct answer is C, Fast Connection Failover (FCF), as it is specifically designed to quickly re-establish connections after a failure. Options A and B do not provide the same level of immediacy in restoring connections, while option D, although it combines FCF with TAF, is not necessary for the requirement of rapid reconnection.
