Google Certified Professional Data Engineer Exam Professional-Data-Engineer Pr¨¹fungsfragen mit Lösungen (Q30-Q35):30. Frage
Your financial services company has a critical daily reconciliation process that involves several distinct steps:
fetching data from an external SFTP server, decrypting the files, loading them into Cloud Storage, and finally running a series of BigQuery SQL transformations. Each step has strict dependencies, and the entire process should notify you if not completed by 7:00 AM. Manual intervention for failures is costly and delays compliance reporting. You need a highly observable and robust solution that supports easy re-runs of individual steps if errors occur. What should you do?
Antwort: D
Begr¨¹ndung:
Cloud Composer (based on Apache Airflow) is designed for workflow orchestration where complex dependencies exist. To achieve high observability and robustness (specifically the ability to re-run individual steps), the workflow must be decomposed into granular tasks.
* Granularity and Re-runs: By defining each step (SFTP fetch, Decrypt, GCS Load, BQ Transform) as a separate task in a DAG, Airflow tracks the state of each individually. If the "BigQuery SQL" step fails, you can "Clear" only that specific task in the UI to re-run it without re-fetching or re-decrypting the data, saving time and costs.
* Observability: Each task has its own logs and status in the Airflow UI. Options B and C (Single Operator/Script) are "black boxes"-if they fail, Airflow only knows the entire script failed, making it difficult to pinpoint where and impossible to re-run just the failed portion.
* SLA and Notifications: Airflow has built-in sla_miss_callbacks and email_on_failure features. You can set an sla parameter of 7:00 AM to automatically trigger alerts if the process is lagging.
* Correcting other options: * A: Splitting the logic between Composer and a separate Scheduler
/Dataflow job breaks the end-to-end lineage and makes it harder to manage dependencies and global SLAs.
* B & C: As mentioned, using a single operator for multiple logic steps defeats the purpose of an orchestrator's monitoring and retry capabilities.
Reference: Google Cloud Documentation on Cloud Composer / Airflow:
"An Airflow DAG is a collection of all the tasks you want to run, organized in a way that reflects their relationships and dependencies... Breaking down your workflow into multiple tasks allows for: Individual retries (re-running only failed parts), Parallel execution, and Clearer monitoring in the Airflow web interface." (Source: Key Airflow Concepts)
"You can use the SLA (Service Level Agreement) feature in Airflow to track whether a task or DAG takes longer than expected to finish... If a task exceeds its SLA, Airflow can send an email alert or trigger a callback function." (Source: Airflow Documentation - SLAs)

32. Frage
Your company is migrating its on-premises data warehousing solution to BigQuery. The existing data warehouse uses trigger-based change data capture (CDC) to apply daily updates from transactional database sources Your company wants to use BigQuery to improve its handling of CDC and to optimize the performance of the data warehouse Source system changes must be available for query m near-real time using tog-based CDC streams You need to ensure that changes in the BigQuery reporting table are available with minimal latency and reduced overhead. What should you do? Choose 2 answers
Antwort: C,D

33. Frage
You need to create a data pipeline that copies time-series transaction data so that it can be queried from within BigQuery by your data science team for analysis. Every hour, thousands of transactions are updated with a new status. The size of the intitial dataset is 1.5 PB, and it will grow by 3 TB per day. The data is heavily structured, and your data science team will build machine learning models based on this dat
a. You want to maximize performance and usability for your data science team. Which two strategies should you adopt? Choose 2 answers.
Antwort: D,E

34. Frage
You are designing a data mesh on Google Cloud by using Dataplex to manage data in BigQuery and Cloud Storage. You want to simplify data asset permissions. You are creating a customer virtual lake with two user groups:
* Data engineers, which require lull data lake access
* Analytic users, which require access to curated data
You need to assign access rights to these two groups. What should you do?
Antwort: D
Begr¨¹ndung:
When designing a data mesh on Google Cloud using Dataplex to manage data in BigQuery and Cloud Storage, it is essential to simplify data asset permissions while ensuring that each user group has the appropriate access levels. Here's why option A is the best choice:
Data Engineer Group:
Data engineers require full access to the data lake to manage and operate data assets comprehensively.
Granting the dataplex.dataOwner role to the data engineer group on the customer data lake ensures they have the necessary permissions to create, modify, and delete data assets within the lake.
Analytic User Group:
Analytic users need access to curated data but do not require full control over all data assets. Granting the dataplex.dataReader role to the analytic user group on the customer curated zone provides read-only access to the curated data, enabling them to analyze the data without the ability to modify or delete it.
Steps to Implement:
Grant Data Engineer Permissions:
Assign the dataplex.dataOwner role to the data engineer group on the customer data lake to ensure full access and management capabilities.
Grant Analytic User Permissions:
Assign the dataplex.dataReader role to the analytic user group on the customer curated zone to provide read- only access to curated data.
