The test prep questions associated with these training aids have not been significantly updated for at least four months. Considering that a significant portion of the test now covers security items from the Nov 2018 Re-Invent conference shouldn’t an update be considered. And an example services now covered by the exam include Macie, Athena, SecureVault and Conditional Access. My recommendation at this point is to search the internet and see what people are saying about this test. I’ve already sat for this exam once and missed by less than three or four questions so any update would have probably helped.
