In my opinion she committed too many chips preflop for her stack size. If she had 3k or so, then yes that raise will work. With more chips you can bet a larger portion of the pot to push out the drawing hands on the flop and not risk a call based on stack size.

I think with the stack size a limp from UTG is the better play. It keeps the pot smaller and allows you to bet out a larger portion of the pot and not commit too much of your stack.
