Which three statements are true about services and transparent application failover (TAF)?

Which three statements are true about services and transparent application failover (TAF)?

A.
If TAF has been configured for a service, sessions using that service fail over to a surviving instance when an outage occurs.

B.
The TAF setting on a service can be none, basic, preconnect, or postconnect, and overrides any TAF setting In the client connection definition.

C.
TAF can restart a query after failover has completed but for other statements, such as insert, update, or delete, the application must resubmit the transaction.

D.
The TAF setting for a client connection overrides any TAF setting In the service definition.

E.
Services simplify the deployment of TAF because by defining a TAF policy for a service, all connections using this service will automatically have TAF enabled.
