I have recently seen in the exam details page that exam duration is 180 minutes instead of 170 mentioned in this video. Did they increase the number of questions or any updates? https://aws.amazon.com/certification/certified-solutions-architect-professional/
From my memory, I think the "official" time varies between 180 and 170 depending on which provider you choose. The reason is that I think one provider includes the survey at the end in the exam in the exam time. They didn’t used to do this but I guess due to the confusion of students, I guess AWS just uses 180 now.
