Question 79: The correct answer should be B,C
Anonymous

Question number 66. The answer should be A. Lambda functions are not shareable across accounts via AWS Resource Access Manager (RAM). You need to export the deployment package (usually from an S3 bucket or code repository) and recreate the functions in the target account. Aurora automated DB snapshots can be shared across AWS accounts. The Target account can restore from the shared snapshot, ensuring that data is preserved with minimal downtime.

Just passed my AZ-104 exam and I’m thrilled! I’m Greg from Ireland, and I found the prep questions on this site incredibly helpful. They gave me a solid idea of the exam format and helped reinforce key topics like Azure AD, storage, and networking. While they’re not a replacement for studying the official Microsoft materials, they’re great for practice and building confidence. I used them alongside the Microsoft Learn content and some labs on Azure. If you’re preparing for AZ-104, I’d definitely recommend using this exam questions and answers for review. It made a big difference for me. Best of luck to everyone studying!

Guys, The content is very similar to real exam. I know cuz I just passed this exam. The only thing to consider is that the free version only give you access to 50% of the qeustions. The rest are part of the paid PDF version. They give 50% discount when buying 2 or more practice questions. To me it was money well spent.
