What applies to you at the next junction?

Your answer is fully correct because both turning left and turning right are allowed options at the next junction according to the road signs shown.

In German traffic rules, the yellow direction sign indicates the directions you can take at the upcoming intersection. It shows that you can turn left towards Fürstenwalde or right towards Vogelsang, but not go straight ahead to Frankfurt, because the road ahead is a dead end.

The blue sign indicates a remainder of 100 meters to a motor vehicle road (Autobahn or similar), so you are approaching a controlled road section.

Thus, you must choose to either turn left or right at the junction, and driving straight ahead is not allowed. Your answer (turn left and turn right) correctly follows this rule.
