A user story is a feature request (or need) expressed from the point of view of a user with a description of the value it provides to that user.
The Daily Scrum was meant for Developers to give each other an idea of the work they had done the day before and their plans for the day in progress. It was never meant for Product Managers or Product Owners to be part of them unless they are taking part of the work in the actual product by working on Sprint Backlog Items.
Even though, the test is your knowledge is about being a Product Owner using the Scrum guide, in reality, the Scrum guide is not enough for you to pass it. Therefore, you are required to find other sources that might help you complement your knowledge for being a good Product Owner using the Scrum framework.
