You administer a Microsoft SQL Server 2012 database. You create an availability group named
haContosoDbs. Your primary replica is available at Server01\Contoso01. You need to configure the
availability group to minimize transaction latency on any available secondary databases. In the event
of a database failure, the designated secondary database should come online automatically. Which
Transact-SQL statement should you use?
A.
ALTER AVAILABILITY GROUP haContosoDbs MODIFY REPLICA ON ‘Server01\Contoso01’
WITH (AVAILABILITY_MODE = ASYNCHRONOUS_COMMIT, FAILOVER_MODE = AUTOMATIC)
B.
ALTER AVAILABILITY GROUP haContosoDbs MODIFY REPLICA ON ‘Server01\Contoso01’
WITH (AVAILABILITY_MODE = SYNCHRONOUS_COMMIT, FAILOVER_MODE = MANUAL)
C.
ALTER AVAILABILITY GROUP haContosoDbs MODIFY REPLICA ON ‘Server01\Contoso01’
WITH (AVAILABILITY_MODE = SYNCHRONOUS_COMMIT, FAILOVER_MODE = AUTOMATIC)
D.
ALTER AVAILABILITY GROUP haContosoDbs MODIFY REPLICA ON ‘Server01\Contoso01’
WITH (AVAILABILITY_MODE = ASYNCHRONOUS_COMMIT, FAILOVER_MODE = MANUAL)
