Questions about 1Z0-042 test

[Brewster]

Hi All,

I was going through the practice questions of exam 1z0-042.
I got following question and options of that question.

Which two steps are performed the first time any UPDATE statement is issued after the instance is started?

A. Creating the parse tree of the statement
B. Writing the modified data blocks to the data files
C. Writing the modified data to the archived redo log files
D. Updating the control file to indicate the most recent checkpoint
E. Updating the data file header to indicate the most recent checkpoint
F. Reading the blocks to database buffer cache if they are not already there

As per my knowledge, answer is A & F.
But it was mentioned that correct answer is C & D.

Can anyone please tell me what is the correct answer?
