Stockfish rates this +0.06, a tiny edge for White. That means the position is dead level, and you should not expect to be winning simply by reaching it.
The practical lesson is simple: both sides are still fully in the game. As White, you want smooth development, safe king placement, and a position that stays easy to play.
The engine’s main answer
The engine’s best move here is g6, continuing g6 c3 Bg7 O-O. That tells you Black can meet your quiet setup with a very natural fianchetto plan.
So in the drill, do not treat this as a forcing line you can memorise move for move. Focus on understanding how to complete development and keep your position compact when Black chooses a setup like this.

Across 61,323 games at this exact position, the results are mixed but not extreme: White wins 41.6%, draws 3.8%, Black wins 54.5%.

Most common replies to know
The most-played continuations from here are Nf6, Nc6, g6, e6, e5, and a6. Those moves show that Black has several normal ways to continue, so your setup needs to stay flexible.
A good drill mindset is to recognise that no single reply settles the game. Keep developing, watch the centre, and be ready for a quiet middlegame rather than an immediate attack.
