一部の候補者は、自社のGCP-DEソフトウェアテストシミュレーターを購入する場合があります。ソフトバージョンをインストールできるパーソナルコンピューターの台数を尋ねられます。実際、コンピューターの数に制限はありません。したがって、GCP-DEソフトウェアテストシミュレータを購入すると、同時にマルチユーザーをサポートします。無制限にコンピューターにインストールできます。あなたが訓練学校である場合、教師が気軽に発表して説明するのに適しています。優れたGCP-DEソフトウェアテストシミュレータは合格率が高く、CertShikenは長期的な協力をお待ちしています。

Google Data Engineer 認定 GCP-DE 試験問題 (Q54-Q59):

質問 # 54
You are running a pipeline in Cloud Dataflow that receives messages from a Cloud Pub/Sub topic and writes the results to a BigQuery dataset in the EU. Currently, your pipeline is located in europe-west4 and has a maximum of 3 workers, instance type n1-standard-1. You notice that during peak periods, your pipeline is struggling to process records in a timely fashion, when all 3 workers are at maximum CPU utilization. Which two actions can you take to increase performance of your pipeline? (Choose two.)

A. Increase the number of max workers
B. Create a new step in your pipeline to write to this table first, and then create a new pipeline to write from Cloud Spanner to BigQuery
C. Create a temporary table in Cloud Bigtable that will act as a buffer for new data
D. Create a new step in your pipeline to write to this table first, and then create a new pipeline to write from Cloud Bigtable to BigQuery
E. Change the zone of your Cloud Dataflow pipeline to run in us-central1
F. Create a temporary table in Cloud Spanner that will act as a buffer for new data
G. Use a larger instance type for your Cloud Dataflow workers

正解：D、G

質問 # 55
Cloud Dataproc is a managed Apache Hadoop and Apache service.

A. Spark
B. Fire
C. Ignite
D. Blaze

正解：A

解説：
Cloud Dataproc is a managed Apache Spark and Apache Hadoop service that lets you use open source data tools for batch processing, querying, streaming, and machine learning.
Reference: https://cloud.google.com/dataproc/docs/

質問 # 56
Suppose you have a table that includes a nested column called "city" inside a column called "person", but when you try to submit the following query in BigQuery, it gives you an error.
SELECT person FROM `project1.example.table1` WHERE city = "London"
How would you correct the error?

A. Add ", UNNEST(city)" before the WHERE clause.
B. Add ", UNNEST(person)" before the WHERE clause.
C. Change "person" to "person.city".
D. Change "person" to "city.person".

正解：B

解説：
To access the person.city column, you need to "UNNEST(person)" and JOIN it to table1 using a comma. Reference:
https://cloud.google.com/bigquery/docs/reference/standard-sql/migrating-from-legacy-sql#nested_repeated_resu

質問 # 57
You are creating a new pipeline in Google Cloud to stream IoT data from Cloud Pub/Sub through Cloud Dataflow to BigQuery. While previewing the data, you notice that roughly 2% of the data appears to be corrupt. You need to modify the Cloud Dataflow pipeline to filter out this corrupt data. What should you do?

A. Add a SideInput that returns a Boolean if the element is corrupt.
B. Add a Partition transform in Cloud Dataflow to separate valid data from corrupt data.
C. Add a GroupByKey transform in Cloud Dataflow to group all of the valid data together and discard the rest.
D. Add a ParDo transform in Cloud Dataflow to discard corrupt elements.

正解：D

質問 # 58
You need to deploy additional dependencies to all of a Cloud Dataproc cluster at startup using an existing initialization action. Company security policies require that Cloud Dataproc nodes do not have access to the Internet so public initialization actions cannot fetch resources. What should you do?

A. Use Resource Manager to add the service account used by the Cloud Dataproc cluster to the Network User role
B. Use an SSH tunnel to give the Cloud Dataproc cluster access to the Internet
C. Deploy the Cloud SQL Proxy on the Cloud Dataproc master
D. Copy all dependencies to a Cloud Storage bucket within your VPC security perimeter

正解：A
