Oracle Database 12c: RAC Administration — Question 53

Which three statements are true about services when used with transparent application failover (TAF) for an administrator-managed RAC database?

Answer options

• A. TAF-enabled sessions fail over to a surviving instance accepting logins for the service.
• B. TAF-settings for the service override TAF settings in TNS entry used by the client.
• C. TAF can restart a query or a transaction after failover.
• D. The TAF settings for a client connections overrides any TAF settings in the service definition.
• E. TAF PRECONNECT requires configuration for the service and in the client TNS entry.

Correct answer: A, B, C

Explanation

Options A, B, and C are correct because they accurately describe how TAF operates with services in a RAC environment. Option D is incorrect as it suggests client connection settings override service settings, which is not the case; service settings take precedence. Option E, while correct, is not one of the three requested statements.
