Show answer

Correct answer: D

When you need to ensure that data is cleared from environments each time an extension is published, the correct schemaUpdateMode property to use is 'Recreate'. This property ensures that the database schema is dropped and recreated, leading to the clearing of all existing data, which is what the company requires.

Correct answer: A

To ensure that the most recent Business Central artifact URL is selected for setting up a local Business Central Development Docker container, you should use the command Get-BcArtifactUrl -type sandbox -select Current. The -select Current parameter is crucial as it specifies that the current, or latest, version of the artifact is to be retrieved, ensuring the Docker container is set up with the most up-to-date version for testing new project ideas.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.
