Your company uses a SQL Server 2005 database. This database contains a trigger named trg_InsertOrders, which fires when order data is inserted into the Orders table. The trigger is responsible for ensuring that a customer exists in the Customers table before data is inserted into the Orders table. You need to configure the trigger to prevent it from firing during the data import process. You must accomplish this goal while using the least amount of administrative effort. Which two Transact-SQL statements can you use to achieve this goal?（）A、 ALTER TABLE OrdersDISABLE TRIGGER trg_InsertOrders B、 DROP TRIGGER trg_InsertOrders C、 DISABLE TRIGGER trg_InsertOrders ON Orders D、 ALTER TRIGGER trg_InsertOrders ON Orders NOT FOR REPLICATION E、 sp_settriggerorder@triggername= 'trg_InsertOrders', @order='None'

Which three statements about STP timers are true？（）A、STP timers values （hello， forward delay， max age） are included in each BPDU.B、A switch is not concerned about its local configuration of the STP timers values. It will only consider the value of the STP timers contained in the BPDU it is receiving.C、To successfully exchange BPDUs between two switches， their STP timers value （hello， forward delay， max age） must be the same.D、If any STP timer value （hello， forward delay， max age） needs to be changed， it should at least be changed on the root bridge and backup root bridge.E、On a switched network with a small network diameter， the STP hello timer can be tuned to a lower value to decrease the load on the switch CPU.F、The root bridge passes the timer information in BPDUs to all routers in the Layer 3 configuration.
