Question #: 20
Topic #: 9

Your company is designing a data store tor internet-connected temperature sensors. The collected data will be used to analyze temperature trends. Which type of data store should you use?

Arelational

Bcolumnar

Cgraph

Dtime series

Show Suggested Answer

Suggested Answer: D

Time series data is a set of values organized by time. Time series databases typically collect large amounts of data in real time from a large number of sources. Updates are rare, and deletes are often done as bulk operations. Although the records written to a time-series database are generally small, there are often a large number of records, and total data size can grow rapidly.

Surprised to see time series as the top option! Isn’t it a bit niche?

Really? I thought relational databases could work for this as well.

But what about columnar stores? They can handle large datasets too.

I’m leaning towards time series as well, especially since we want to analyze trends. It just makes sense for time-based data!

I feel like a relational database could work, but it seems like overkill for just temperature trends.

I remember practicing a question about data stores, and I think columnar databases are good for analytics, but they might not be the best fit here.

I think we might need a time series database since we're dealing with temperature data over time, but I'm not entirely sure.

This looks like a straightforward question about Alibaba Cloud Container Service for Kubernetes (ACK) auto scaling. I'll need to carefully review the instance types listed and determine which ones can be scaled.

Okay, let's see. Public health activities, child abuse reporting, and medical emergencies are all exceptions, so the answer must be D - disclosing to a third-party billing administrator.

Hmm, I'm a bit unsure about this one. I remember discussing project scope management, but I can't quite recall the specific technique used in the initial development of the plan. Let me think this through step-by-step.
