How to prepare for the DP-203 Certification Exam?

Introduction:

Data engineering jobs are very much in demand. And getting a certificate in a topic is a great way to learn and deepen and prove your skills.

Each cloud computing provider issues a special certification for their Data Engineering services.

The Azure DP-203 is a good certificate examination that is hard to pass.

How To Prepare For The DP-203 Exam:

Online courses:

There is official content from Microsoft, which looks great for the exam. This official content mixes text and video with extra text weight.

Getting hands over the official content:

Microsoft, on their website, mentions a teacher-led training option. While watching videos, some people take notes to assist organise their thoughts and ensure that they comprehend. I also did not take notes, although I did write about previous lessons.

How to get practice for the test:

The top tip is to use the official Microsoft practice testing tool. It is worth the expense.

Features of the Practice Testing tool:

The formal practice test allows you to choose the length of the test no matter how long you have to practice at that time. You can stop if it tells you the answers immediately or at the end.

Practice Testing Books:

There are a lot of books. They are not as good as quality as performance tests. The definitions are also not very detailed but still useful.

Targeted Topics:

You need to be clear about some topics because they seem to be the most common, and most questions are from those. The highlights are:

• Storage tiers. If you know the heat, cold and archive, you will get some marks.

• Star schema.

• changing dimension types. Wikipedia explains this well.

• Distribution of dedicated Synapse tables.

• When should you use JSON, Avro, CSV, or Parquet? (The answer is nearly always that parquet is the ideal for requesting data on the scale, but they also like to point out that avro is good for timed data.)

• Syntax for file writing or live streaming using Spark.

Conclusion:

If you do well consistently in practice tests, improve your guessing ability, and can make guessing faster, then you are ready to give the Azure DP-203 test.
