The Process of Decision Making in Chess Volume 2: Practice positions and solutions. Position 9.7

White moves Rc2, and I am struggling how black can gain an advantage. All I can suggest is that black moves his bishop to h5 to take out white's knight
Solve the challenge below:
Diagram 9.7- white is the proud owner of a set of double isolated pawns on the c file. There is also an isolated pawn on the A file, and these two observations caught black’s tactical eye. If he could put a rook on d2, then the fate of the a2 pawn would look sealed. Therefore, Ne4! going to d2 forcing the exchange of knights followed by Rd2. Black is in fact using the current weakness of the c file pawns to attack another weakness, a common technique that usually means having a killer initiative.
Challenge: does white have a decent reply to Ne4 and the plan that’s behind it? If yes, does it mean that white is doing ok here, or is there any way to create further progress for black from that point?
