Hi ! This is a short article where I share my thoughts and steps on taking Google Cloud Professional Data Engineer certification exam in one shot in 2023. I will address the following questions:
What is the exam about?
Steps I took before going to the exam
On the exam date
1. 關於考試-What is the exam about?
Duration: 2 hours
Number of questions: 50
Designing Data Processing Systems
Building and Operationalizing Data Processing Systems
Operationalizing Machine Learning Models
Ensuring Solution Quality
2. 考試前做的幾個步驟-Steps I took before going to the exam
訓練 - Training (1–1.5 months)
Udemy — GCP — Google Cloud Professional Data Engineer Certification by Ankit Mistry (Cost: $12.99) (Total: 23.5 hours)
上機練習-Hands-on practice (1 month)
cloudskillsboost (a platform powered by Qwiklabs), Qwiklabs for hands-on GCP (quest is a series of labs)
探索-Quest— Data, ML, AI
I use cloudskillsboost to practice GCP because my company is a partner from Google.
模擬考-Mock exams (1–2 weeks)
Skillcertpro — Google Cloud Professional Data Engineer Exam Questions 2023 (Cost: $19.99)
Examtopics — Google Professional Data Engineer Exam (My company bought full version with pdf format)
Skillcertpro has more accurate answers than Examtopics, although Examtopics display community voting results and comments. Sometimes both platforms give contradictive answers. Most of the questions in the actual exam are very similar to the mock exams, and I would say 80% similar. No need to worry about the accuracy in your mock exam, I could complete them at 60%+ accuracy every time. In the real test, the requirement to pass is 70%.
You have some data, which is shown in the graphic below. The two dimensions are X and Y, and the shade of each dot represents what class it is. You want to classify this data accurately using a linear algorithm. To do this you need to add a synthetic feature. What should the value of that feature be?
Skillcertpro: correct answer : cos(x)
Examtopics: correct answer: cos(x)
Examtopics community vote most(77%): x²+y²
Question in Examtopics
You are responsible for writing your company’s ETL pipelines to run on an Apache Hadoop cluster. The pipeline will require some checkpointing and splitting pipelines. Which method should you use to write the pipelines?
A. PigLatin using Pig
B. HiveQL using Hive
C. Java using MapReduce
D. Python using MapReduce
Examtopics give answer D
Examtopics community most vote A
Question with ambiguous answer:
You are deploying MariaDB SQL databases on GCE VM Instances and need to configure monitoring and alerting. You want to collect metrics including network connections, disk IO and replication status from MariaDB with minimal development effort and use StackDriver for dashboards and alerts.

D. Install the StackDriver Agent and configure the MySQL plugin.
Skillcertpro answer: A
Examtopics answer : C
Examtopics community vote most: D
3. 在考試當天-On the exam date
在回答了50 個問題後，一個簡短的問券會跳出問你對考試的建議，問券完後pass 或 fail及時會顯示在螢幕上，但沒有分數幾分。你將會在7到10天之後在emal 裡收到正式的證書。
My scheduled exam time is 10AM. I woke up early in the morning and skim through mock exams to have better feelings about what will appear in real exam. At the test center, they will ask you about photo ids (passport, and credit card), then I provide a passcode sent by test center. The testing room is much quieter than home. One person for one room. I would recommend taking exam at test center rather than on-line at-home exam.
After you answer 50 questions, a short survey will show up. After the short survery, a pass or fail will show up on the screen without score details. You will receive official certification in your email in-box in 7 to 10 days.
4. 正式證書-Official certification
I passed my exam at the exam center on Feb 2, got the official email from Google on Feb 10. Once you’ve passed, you’ll be emailed a redemption code alongside your official Google Cloud Professional Data Engineer certification. Congratulations!
I spent some time to search on-line courses, but these are what came out to me. You may adjust accordingly based on your time and what you really want to get out of the certification. I sincerely hope that you are able to pass the exam with these tips and apply these knowledge at your work or side project!
