Child Faults After Write

Question Text

What causes the page faults registered by the child after the fifth step?

Question Answers

• The child writes data to the frames it previously shared with its parent and the copy-on-write mechanism copies and remaps them before writing said data

• Demand paging lazily allocates pages but does not cause these page faults in copy-on-write.

• Creating the child process inherently duplicates some frames

• They are caused by the loader forking itself when creating the child process

• They are caused by the bash process forking itself when creating the child process
