Question

is this scenario possible......"TLB hit with page fault";

Answer 1

yes , it can be

for example if you want to write to " write protected memory " then in this scenario  A TLB exists and hit will occur  but the translated  address leads to  a trap because you're trying to write to a memory that's read-only

or second case may be you are trying to access dirty page

page fault may  be due to

1)a missing page or

2)a dirty page or

3)access permission mismatch. So a TLB hit can still lead to a page fault
