Very helpful video. However, option B doesn't mention anything about creating a deployment pipeline - it just says to use one workspace and then publish an app from that workspace. But we need to "completely separate development and production assets such as databases, reports and dashboards". The only option here that suits is to create separate workspaces.

Totally agree. Besides logical and trchnical understanding, the exam questions require a good understanding of language - which is tough for non native english speakers

C is correct but don't agree with your explication You can have more than Dataset in your workspace (Tested) so this is not the reason for C ==> the reason is that in the question the say "prevent end users from viewing the development assets" In only one workspace it's not possible, this is why C ----------------------------------------------- Because if there is only one workspace (like in "D answer" ) the end user will have also access to Dev Report (because with the Viewer rôle they can see all the reports and dashbords) ------------------------- Hope it's clear

It might be the case that the dataset for production is different than the dataset for development. "Now, you are close to completing the pipeline, transitioning from development to testing, and finally to production. At this stage, you need to create a data source rule for the OrdersFigures dataset in the workspace to ensure that you are using production data. In this instance, you will be changing your source from the test to the production folder version of the orders.csv file, as shown in the following screenshot." https://docs.microsoft.com/en-us/learn/modules/create-manage-workspaces-power-bi/4-development-lifecycle-strategy

But in A, it mentions that dataset is shared.....
