Actual exam question for Microsoft's DP-900 exam

Question #: 25
Topic #: 7

You need to recommend a non-relational data store that is optimized for storing and retrieving files, videos, audio stream, and virtual disk images. The data store must store data, some metadata, and a unique ID for each file.

Which type of data store should you recommend?

Adocument

Bkey/value

Cobject

Dcolumnar

Show Suggested Answer

Suggested Answer: C

Object storage is optimized for storing and retrieving large binary objects (images, files, video and audio streams, large application data objects and documents, virtual machine disk images). Large data files are also popularly used in this model, for example, delimiter file (CSV), parquet, and ORC. Object stores can manage extremely large amounts of unstructured data.

Columnar? Seems like an odd choice for files and media.

Wait, can key/value stores even manage that much data?

Columnar stores seem off for this scenario; I believe they’re more for analytical queries, not file storage.

I practiced a question like this, and I feel like document stores are more suited for structured data rather than files.

I'm not entirely sure, but I remember something about key/value stores being good for simple data retrieval.

I think the object data store might be the best choice here since it can handle files and metadata together.

Hmm, this looks like a tricky one. I'll need to think carefully about the definition of ILFs to determine which of these options might qualify.

Hmm, I'm a bit confused on this one. I know Kubernetes has a lot of different features, but I'm not sure which one would be best for maintaining consistent hostnames. I'll have to think this through carefully.

This looks like a classic control chart question. I'd start by looking for any obvious patterns or outliers in the data, then consider whether I need to collect more data or dig deeper into the root causes.
