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

The Fast Connection Failover (FCF) feature is an Oracle RAC/Fast Application Notification (FAN) client implemented through the connection pool. The feature requires the use of an Oracle JDBC driver and an Oracle RAC database. References: https://docs.oracle.com/cd/B28359_01/java.111/e10788/rac.htm
