    TDE and In-Memory OLTP are far to be my favorite topics ( truly I am a beginner ) and I have to admit that if I provided the good answers , it is only because I attended a session about this topic during the Paris SQL Server days last year. As I have a good remembrance , I got easily one point . Anyway , thanks for the person who succeeded to explain fully and plainly this "hard" topic.

    An interesting question, but slightly spoiled by the format of the answers (select three from five, where two pairs were mutually exclusive, meaning that the singleton must perforce be one of the true answers)

    Thank you for the post, Pramod, interesting one. I was sure of two except the filegroup one and had to check on that.

    Wait, so if the memory optimized filegroup is not encrypted, does that mean the data is vulnerable? Should in-memory OLTP tables not be used with sensitive data?

    Encrypted filegroups are also decrypted while in memory.

    Yes, but for the in-memory stuff the checkpoint files aren't encrypted either - so the data is not encrypted when secured.

    I think in such questions where it's asked to choose multiple correct answers, it will be good to have more points rather just 1. Thoughts?

    Thanks.

    Sometimes they have more points. Sometimes they don't. 🙂

    Nice question. I haven't gotten to play with 2014 yet at work, so I had to do research to find the answer. I always enjoy learning something new. 🙂
