最新的 Google Cloud Certified Professional-Data-Engineer 免費考試真題 (Q120-Q125):

問題 #120
You are working on a niche product in the image recognition domain. Your team has developed a model that is dominated by custom C++ TensorFlow ops your team has implemented. These ops are used inside your main training loop and are performing bulky matrix multiplications. It currently takes up to several days to train a model. You want to decrease this time significantly and keep the cost low by using an accelerator on Google Cloud. What should you do?

A. Use Cloud TPUs after implementing GPU kernel support for your customs ops.
B. Use Cloud TPUs without any additional adjustment to your code.
C. Stay on CPUs, and increase the size of the cluster you're training your model on.
D. Use Cloud GPUs after implementing GPU kernel support for your customs ops.

答案：A

解題說明：
Cloud TPUs are not suited to the following workloads: [...] Neural network workloads that contain custom TensorFlow operations written in C++. Specifically, custom operations in the body of the main training loop are not suitable for TPUs.

問題 #121
Your car factory is pushing machine measurements as messages into a Pub/Sub topic in your Google Cloud project. A Dataflow streaming job, that you wrote with the Apache Beam SDK, reads these messages, sends acknowledgment to Pub/Sub, applies some custom business logic in a DoFn instance, and writes the result to BigQuery. You want to ensure that if your business logic fails on a message, the message will be sent to a Pub/Sub topic that you want to monitor for alerting purposes. What should you do?

A. Enable retaining of acknowledged messages in your Pub/Sub pull subscription. Use Cloud Monitoring to monitor the subscription/num_retained_acked_messages metric on this subscription.
B. Use an exception handling block in your Dataflow's DoFn code to push the messages that failed to be transformed through a side output and to a new Pub/Sub topic. Use Cloud Monitoring to monitor the topic/num_unacked_messages_by_region metric on this new topic.
C. Enable dead lettering in your Pub/Sub pull subscription, and specify a new Pub/Sub topic as the dead letter topic. Use Cloud Monitoring to monitor the subscription/dead_letter_message_count metric on your pull subscription.
D. Create a snapshot of your Pub/Sub pull subscription. Use Cloud Monitoring to monitor the snapshot/ num_messages metric on this snapshot.

答案：B

問題 #122
You need to look at BigQuery data from a specific table multiple times a day. The underlying table you are querying is several petabytes in size, but you want to filter your data and provide simple aggregations to downstream users. You want to run queries faster and get up-to-date insights quicker. What should you do?

A. Create a materialized view based off of the query being run.
B. Use a cached query to accelerate time to results.
C. Limit the query columns being pulled in the final result.
D. Run a scheduled query to pull the necessary data at specific intervals daily.

答案：D

解題說明：
Materialized views are precomputed views that periodically cache the results of a query for increased performance and efficiency. BigQuery leverages precomputed results from materialized views and whenever possible reads only changes from the base tables to compute up-to-date results. Materialized views can significantly improve the performance of workloads that have the characteristic of common and repeated queries. Materialized views can also optimize queries with high computation cost and small dataset results, such as filtering and aggregating large tables. Materialized views are refreshed automatically when the base tables change, so they always return fresh data. Materialized views can also be used by the BigQuery optimizer to process queries to the base tables, if any part of the query can be resolved by querying the materialized view. References:

問題 #123
Your company has data assets across multiple Cloud Storage buckets and BigQuery datasets containing raw and processed data. The requirement is to establish a unified data governance framework that allows for centralized metadata discovery, data quality monitoring, and consistent security policy application across these various data stores without physically moving or duplicating the data. You need to implement a solution to achieve this federated governance.
What should you do?

A. 1. Use Dataplex to organize the BigQuery datasets and Cloud Storage buckets into lakes and zones.
2. Use Dataplex for automated metadata discovery, centralized security policy management, data profiling, and data quality tasks.
B. 1. Export metadata out of Dataplex Universal Catalog by running a metadata export job.
2. Implement Dataproc Metastore to manage table schemas and Apache Hive metastore for metadata discovery.
3. Manage security using a combination of BigQuery row-level security and Cloud Storage policies.
C. 1. Deploy a centralized Cloud SQL database to store metadata extracted from BigQuery and Cloud Storage using custom scripts.
2. Integrate the database with Looker Studio for data discovery and visualization.
3. Implement a custom policy engine using Cloud Run functions triggered by changes in IAM policies to enforce consistent security across projects.
D. 1. Create a Looker Studio dashboard on BigQuery INFORMATION_SCHEMAviews to visualize and monitor data quality.
2. Manage security using IAM policies at the project level, supplemented by BigQuery authorized views for granular access control.

答案：A

解題說明：
Dataplex provides a federated data governance layer that logically organizes BigQuery datasets and Cloud Storage buckets into lakes and zones without moving data. It enables centralized metadata discovery through automatic cataloging, supports data profiling and data quality monitoring, and enforces consistent security policies across heterogeneous data stores, meeting all requirements for unified governance.

問題 #124
Flowlogistic wants to use Google BigQuery as their primary analysis system, but they still have Apache Hadoop and Spark workloads that they cannot move to BigQuery. Flowlogistic does not know how to store the data that is common to both workloads. What should they do?

A. Store the common data in BigQuery and expose authorized views.
B. Store the common data encoded as Avro in Google Cloud Storage.
C. Store the common data in BigQuery as partitioned tables.
D. Store he common data in the HDFS storage for a Google Cloud Dataproc cluster.

答案：A
