The qualifying rows under Repeatable read will ensure that

Answer / sf
In RR isolation level, all the pages fetched in the cursor
are locked till end of transaction. This is the safest way
to ensure that no concurrent update happened when the
cursor was actiong on this data.
The confusion would be on CS . In CS only the page having
the relevant data would be locked. As the page size is 4k ,
we may lock more than one row of a table based on row size
and table space organization.
