1. 關於考試-What is the exam about?

Duration: 2 hours

Cost: $200

Number of questions: 50

段落:

  • 設計資料處理系統

  • 打造與維運資料處理系統

  • 維運機器學習魔贏

  • 確保解決方案的品質

Sections :

  • 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有比Examtopic更多正確的答案,即使Examtopics可顯示大眾投票和註解。有時候兩個平台給出相互矛盾的答案,大多數的模擬考題的問題與真實考試非常像,感覺有80%像。不需要太過擔心模擬考的準確率,我在模擬考拿到60+%的準確率,而真實的考試通過要求要70%,我也是通過了。

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%.

Question:

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.

What should you do?

A. Install the OpenCensus Agent and create a custom metric collection application with a StackDriver exporter.

B. Place the MariaDB instances in an Instance Group with a Health Check.

C. Install the StackDriver Logging Agent and configure fluentd in_tail plugin to read MariaDB logs.

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

我排定的考試時間是早上10點,我當天早起很快掃過模擬考題來對真實考試的做題感覺更有感。在考試中心,他們會偵你要兩張有照片的ID(護照,信用卡)或是(護照,國民生份證),然後提供考試中心寄的passcode。考場比家裡考試安靜多了,一個人一間房間,我會見要到考試中心考場而不是在家的上機考。

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

我在考試中心2月2號考過考試,等到2月10號才從Google 收到email說明正式通過考試。通過考試的email會寄出並附上線上小物的免費兌換碼,恭喜啦~~

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!

5. 結論-Conclusion

我花了一些時間在找網路線上課程,這篇文章的分享是握最後用上的,你可能可以根據你的時間和你想從考試得到怎麼再稍加調整。我衷心希望你可以參考這篇文章的準備技巧來通過考試,並運用技能在工作上。

(請相信我們,並關注訂閱電子報)

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!
