Microsoft DP-900 Exam - Topic 3 Question 38 Discussion

Posted by Samira on May 04, 2022 at 08:10 PM

Your company needs to design a database that illustrates the relationships between utilization levels of individual network devices across a local area network.

Which type of data store should you use?

Suggested Answer: A

Data as it appears in the real world is naturally connected. Traditional data modeling focuses on defining entities separately and computing their relationships at runtime. While this model has its advantages, highly connected data can be challenging to manage under its constraints.

A graph database approach relies on persisting relationships in the storage layer instead, which leads to highly efficient graph retrieval operations. Azure Cosmos DB's Gremlin API supports the property graph model.

Columnar? Really? That seems like an odd choice here.

Wait, can a document store even manage network device relationships?

Definitely going with graph, it handles connections well.

I think key/value would be too simplistic for this.

Graph databases are perfect for showing relationships!

I’m a bit confused about the columnar option. I thought those were mainly for analytical queries, not for tracking device relationships.

This question feels familiar; I think we practiced something similar where we had to choose between graph and document stores. Graph seems more fitting for relationships.

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

I think a graph database might be the best choice here since it can effectively represent relationships between devices and their utilization levels.

This looks like a straightforward question about setting up reporting for monthly revenue projections. I think I'll go with option B - creating opportunity products with formula fields for each month's value. That seems like the most direct way to track the monthly revenue data.

Okay, I've got this. The key is to use address translation enabled and port translation disabled to preserve the client's source IP across the different ISP paths.

I'm a bit confused on the differences between some of these Citrix technologies. I'll need to review the details to determine the most efficient approach.

This question is tricky! I practiced something similar where I had to choose medications not included in certain classifications. I wonder if it could be Oxygen since it's a gas and not a drug in the traditional sense.
