Google GCP-DE pass test : Data Engineer

Fast learning with high-quality products

There is no denying that preparing for the exam is a time-consuming as well as energy-consuming process without valid GCP-DE study guide materials, while the paradox is that a majority of the candidates for the exam are workers who don't have enough time to spend on preparing, and the good news for you is that our company is aimed at solving this problem by releasing high passing-rate GCP-DE training materials for all of the workers in this field. We have employed a large number of the leading experts in this field to compile our high-quality GCP-DE exam torrent, and we have put forces on the efficiency of our study material. Facts proved that almost all of the candidates can pass the exam as well as getting the certification only after practicing our high-quality GCP-DE study guide materials for 20 to 30 hours, which means that you can get success with the minimum of time and effort.

Favorable price

Our company has a profound understanding of the psychology of consumers and we always would like to take the needs of our customers into consideration (GCP-DE study guide materials), it is universally acknowledged that the popularity of a company is driven not only by the vast selection and the high level of customer service, but also -- and mainly -- by the favorable price as well as the deep discounts the company regularly offers. So in order to let our GCP-DE training materials available to as many workers in this field as possible, we have always kept the favorable price for our GCP-DE exam torrent materials even though our products have been acclaimed as the most effective and useful study materials in this field by all of our customers in the international market.

Google Data Engineer Sample Questions:

1. Which Cloud Dataflow / Beam feature should you use to aggregate data in an unbounded data source every hour based on the time when the data entered the pipeline?

A) A processing time trigger
B) An event time trigger
C) An hourly watermark
D) The with Allowed Lateness method

2. 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.

A) Copy a daily snapshot of transaction data to Cloud Storage and store it as an Avro fil
B) Use BigQuery UPDATE to further reduce the size of the dataset.
C) Use BigQuery'ssupport for external data sources to query.
D) Develop a data pipeline where status updates are appended to BigQuery instead of updated.
E) Preserve the structure of the data as much as possible.
F) Denormalize the data as must as possible.

3. You launched a new gaming app almost three years ago. You have been uploading log files from the previous day to a separate Google BigQuery table with the table name format LOGS_yyyymmdd. You have been using table wildcard functions to generate daily and monthly reports for all time ranges. Recently, you discovered that some queries that cover long date ranges are exceeding the limit of 1,000 tables and failing. How can you resolve this issue?

A) Convert the sharded tables into a single partitioned table
B) Convert all daily log tables into date-partitioned tables
C) Create separate views to cover each month, and query from these views
D) Enable query caching so you can cache data from previous months

4. You work for an economic consulting firm that helps companies identify economic trends as they happen. As part of your analysis, you use Google BigQuery to correlate customer data with the average prices of the 100 most common goods sold, including bread, gasoline, milk, and others. The average prices of these goods are updated every 30 minutes. You want to make sure this data stays up to date so you can combine it with other data in BigQuery as cheaply as possible. What should you do?

A) Store the data in Google Cloud Datastor
B) Load the data every 30 minutes into a new partitioned table in BigQuery.
C) Use Cloud Dataflow to query BigQuery and combine the data programmatically with the data stored in Google Cloud Storage.
D) Use Google Cloud Dataflow to query BigQuery and combine the data programmatically with the data stored in Cloud Datastore
E) Store the data in a file in a regional Google Cloud Storage bucke
F) Store and update the data in a regional Google Cloud Storage bucket and create a federated data source in BigQuery

5. You architect a system to analyze seismic dat
a. Your extract, transform, and load (ETL) process runs as a series of MapReduce jobs on an Apache Hadoop cluster. The ETL process takes days to process a data set because some steps are computationally expensive. Then you discover that a sensor calibration step has been omitted. How should you change your ETL process to carry out sensor calibration systematically in the future?

A) Add sensor calibration data to the output of the ETL process, and document that all users need to apply sensor calibration themselves.
B) Develop an algorithm through simulation to predict variance of data output from the last MapReduce job based on calibration factors, and apply the correction to all data.
C) Introduce a new MapReduce job to apply sensor calibration to raw data, and ensure all other MapReduce jobs are chained after this.
D) Modify the transformMapReduce jobs to apply sensor calibration before they do anything else.
