Exam 1z0-071 topic 1 question 159 discussion

The Transaction END with Comitt or DDL The new Transaction starts with INSERT, UPDATE, DEL, MERGE (Not even select TESTED) OR A transaction can be start manually by begin transaction command (which is irrelevent in context of this question).

A. after successfully executing a CREATE TABLE statement followed by a CREATE INDEX statement CREATE WILL END THE TRANSACTION BUT AGAIN CREATE INDEX WILL NOT START NEW TRANSACTION. FALSE B. after successfully executing a TRUNCATE statement followed by a DML statement. TRUNC WILL END TRANS... AND LET SUPPOSE DML IS NOT SELECT IN THIS CASE SO THIS IS A POSSIBLE TRUE. TRUE C. after successfully executing a DML statement following a failed DML statement. DML WILL NOT END TRANSATION AT ALL. FALSE D. after successfully executing a CREATE TABLE AS SELECT statement followed by a SELECT FOR UPDATE statement. CREATE IS DDL WHICH IS IMPLICIT COMIT AND SELECT FOR UPDATE IS A START OF NEW TRANSACTION. TRUE E. after successfully executing a COMMIT or ROLLBACK followed by a DML statement. SO COMIT END TRANSACTION AND DML CAN POTENTIALLY START NEW TRANSACTION (OTHER THAN SELECT). TRUE F. after successfully executing a COMMIT or ROLLBACK followed by a SELECT statement. TRANSACTION ENDS HOWEVER ONLE SELECT, LET SAY SELEC * FROM EMP WILL NOT START A NEW TRANSACTION. FALSE TRUE ---- BDE

BDE is correct

BEST ANSWERS

BDE is correct, tested all on DB. F is incorrect as SELECT is a limited DML statement which means it can only access data in the database, it cannot manipulate data.

I would said BDE because STATUS means that the Transaction must be active so not yet completed

I would say BDE

I think new transaction can't start in the following case. C.after successfully executing a DML statement following a failed DML statement and I didn't find the difference between E and F.Can I get any reference link?
