I feel like OTS and HOLO were part of the examples we went over, but I’m uncertain about AnolyticDB.

I have a vague recollection of MongoDB being mentioned in our study materials, but I can't recall if it's supported.

I think Oracle is definitely a source for DLA, I practiced a similar question last week that mentioned it.

I remember that Data Lake Analytics can connect to various databases, but I'm not sure if MySQL is one of them.

I'm a bit confused about some of these less common options like OTS, AnolyticDB, and HOLO. I'll need to research those a bit more.

Okay, let's see... I know DLA can handle structured data, so I'll definitely check the SQL-based options like MySQL and Oracle.

Hmm, this looks like a tricky one. I'll need to think carefully about the different data sources DLA can work with.

Hmm, OSS? Is that some kind of operating system storage? I'm not sure about that one. But I agree with the other candidates, A, B, C, D, E, and G are the correct answers.
