I don’t want to tell you that this practice test is the best in Udemy. But i want to assure that all the content of these practice test will be super easy to digest and remember.
Why is that?
Actually, It takes a lot of time for me (roughly 3 months – from March to June 2021) to collect – prepare – do a lot of research to make sure that:
1.Short and to-the-point
A lot of questions material out there is lengthy and hard to digest. Normally, they will take the text from official website of Google. And of course, these texts are boring and sleepy.
For me, all explanations must be explained LIKE I’M TALKING WITH YOU. I’m always trying to put myself as you to solve the problem. To be honest, as a senior software developer, I hate lengthy explanation. Lengthy explanation only wastes your time and make you confusing quickly. And you will be lost in information forest.
2.Condense information into tiny tips and tricks
I love small tips and tricks in the exam. I bet you love too.
I always try to think and find the smart way to summarize boring knowledge. And you will see A LOT OF TIPS AND TRICKS in these practice test. It will help you memorize key information and have a 10.000ft view of knowledge better.
You are building an application that stores relational data from users. Users across the globe will use this application. Your CTO is concerned about the scaling requirements because the size of the user base is unknown. You need to implement a database solution that can scale with your user growth with minimum configuration changes. Which storage solution should you use?
A. Cloud SQL
B. Cloud Spanner
C. Cloud Firestore
D. Cloud Datastore
B is correct.
Cloud SQL for small relational data, scaled manually
Cloud Spanner for relational data, scaled automatically
Cloud Firestore for app-based data
Cloud Datastore for non-relational data
Finally, I don’t also want to waste your time reading THIS description. So be confident to give this practice a chance and you know, you will be back money in 30 days if you don’t like.
P/S: if you find these explanations helpful, please leave a good comment. It will motivate me to keep making it better and be also a good reference for other learners. Thanks
