How TAF works in MAA architecture (RAC Plus Data gaurd)

 All,

I have configured completed MAA architecture, my Primary and Standby databases are RAC and , My within RAC, Failover and Load balancing work as expected. Even my following TNS entery is also working as expected. But still I have some questions.

My tns enetry.

DV00AIX_DBA=
        (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST =standby-node1)(PORT = 1527))
        (ADDRESS = (PROTOCOL = TCP)(HOST =standby-node2)(PORT = 1527))

(ADDRESS = (PROTOCOL = TCP)(HOST =Primary-node1)(PORT = 1527))
        (ADDRESS = (PROTOCOL = TCP)(HOST =Primary-node2)(PORT = 1527))

        (CONNECT_DATA =
        (SERVER = DEDICATED)
        (SERVICE_NAME = DV00AIX_DBA)
        (FAILOVER_MODE =
                (TYPE = SELECT)
                (METHOD = BASIC)
                (RETRIES = 4)
                (DELAY = 1)
        )
         )
        )

My questions

1) When I try to connect to database using DV00AIX_DBA, tns enerty, will the sqlplus will even try to connect to STANDBY node's as well or only Primary nodes?
