Google Certified Professional Data Engineer Exam Sample Questions (Q254-Q259):

NEW QUESTION # 254
MJTelco Case Study
Company Overview
MJTelco is a startup that plans to build networks in rapidly growing, underserved markets around the world.
The company has patents for innovative optical communications hardware. Based on these patents, they can create many reliable, high-speed backbone links with inexpensive hardware.
Company Background
Founded by experienced telecom executives, MJTelco uses technologies originally developed to overcome communications challenges in space. Fundamental to their operation, they need to create a distributed data infrastructure that drives real-time analysis and incorporates machine learning to continuously optimize their topologies. Because their hardware is inexpensive, they plan to overdeploy the network allowing them to account for the impact of dynamic regional politics on location availability and cost.
Their management and operations teams are situated all around the globe creating many-to-many relationship between data consumers and provides in their system. After careful consideration, they decided public cloud is the perfect environment to support their needs.
Solution Concept
MJTelco is running a successful proof-of-concept (PoC) project in its labs. They have two primary needs:
* Scale and harden their PoC to support significantly more data flows generated when they ramp to more than 50,000 installations.
* Refine their machine-learning cycles to verify and improve the dynamic models they use to control topology definition.
MJTelco will also use three separate operating environments - development/test, staging, and production - to meet the needs of running experiments, deploying new features, and serving production customers.
Business Requirements
* Scale up their production environment with minimal cost, instantiating resources when and where needed in an unpredictable, distributed telecom user community.
* Ensure security of their proprietary data to protect their leading-edge machine learning and analysis.
* Provide reliable and timely access to data for analysis from distributed research workers
* Maintain isolated environments that support rapid iteration of their machine-learning models without affecting their customers.
Technical Requirements
* Ensure secure and efficient transport and storage of telemetry data
* Rapidly scale instances to support between 10,000 and 100,000 data providers with multiple flows each.
* Allow analysis and presentation against data tables tracking up to 2 years of data storing approximately
100m records/day
* Support rapid iteration of monitoring infrastructure focused on awareness of data pipeline problems both in telemetry flows and in production learning cycles.
CEO Statement
Our business model relies on our patents, analytics and dynamic machine learning. Our inexpensive hardware is organized to be highly reliable, which gives us cost advantages. We need to quickly stabilize our large distributed data pipelines to meet our reliability and capacity commitments.
CTO Statement
Our public cloud services must operate as advertised. We need resources that scale and keep our data secure. We also need environments in which our data scientists can carefully study and quickly adapt our models. Because we rely on automation to process our data, we also need our development and test environments to work as we iterate.
CFO Statement
The project is too large for us to maintain the hardware and software required for the data and analysis. Also, we cannot afford to staff an operations team to monitor so many data feeds, so we will rely on automation and infrastructure. Google Cloud's machine learning will allow our quantitative researchers to work on our high- value problems instead of problems with our data pipelines.
MJTelco's Google Cloud Dataflow pipeline is now ready to start receiving data from the 50,000 installations.
You want to allow Cloud Dataflow to scale its compute power up as required. Which Cloud Dataflow pipeline configuration setting should you update?

  • A. The zone
  • B. The number of workers
  • C. The maximum number of workers
  • D. The disk size per worker

Answer: A


NEW QUESTION # 255
When a Cloud Bigtable node fails, ____ is lost.

  • A. the time dimension
  • B. the last transaction
  • C. all data
  • D. no data

Answer: D

Explanation:
A Cloud Bigtable table is sharded into blocks of contiguous rows, called tablets, to help balance the workload of queries. Tablets are stored on Colossus, Google's file system, in SSTable format. Each tablet is associated with a specific Cloud Bigtable node. Data is never stored in Cloud Bigtable nodes themselves; each node has pointers to a set of tablets that are stored on Colossus. As a result:
Rebalancing tablets from one node to another is very fast, because the actual data is not copied. Cloud Bigtable simply updates the pointers for each node. Recovery from the failure of a Cloud Bigtable node is very fast, because only metadata needs to be migrated to the replacement node.
When a Cloud Bigtable node fails, no data is lost

NEW QUESTION # 256
Your weather app queries a database every 15 minutes to get the current temperature. The frontend is powered by Google App Engine and server millions of users. How should you design the frontend to respond to a database failure?

  • A. Issue a command to restart the database servers.
  • B. Retry the query with exponential backoff, up to a cap of 15 minutes.
  • C. Reduce the query frequency to once every hour until the database comes back online.
  • D. Retry the query every second until it comes back online to minimize staleness of data.

Answer: B

NEW QUESTION # 257
You have spent a few days loading data from comma-separated values (CSV) files into the Google
BigQuery table CLICK_STREAM. The column DTstores the epoch time of click events. For convenience,
you chose a simple schema where every field is treated as the STRINGtype. Now, you want to compute
web session durations of users who visit your site, and you want to change its data type to the
TIMESTAMP. You want to minimize the migration effort without making future queries computationally
expensive. What should you do?

  • A. Add two columns to the table CLICK STREAM: TSof the TIMESTAMPtype and IS_NEWof the
    BOOLEANtype. Reload all data in append mode. For each appended row, set the value of IS_NEWto
    true. For future queries, reference the column TSinstead of the column DT, with the WHEREclause
    ensuring that the value of IS_NEWmust be true.
  • B. Add a column TSof the TIMESTAMPtype to the table CLICK_STREAM, and populate the numeric
    values from the column TSfor each row. Reference the column TSinstead of the column DTfrom now
    on.
  • C. Construct a query to return every row of the table CLICK_STREAM, while using the built-in function to
    cast strings from the column DTinto TIMESTAMPvalues. Run the query into a destination table
    NEW_CLICK_STREAM, in which the column TSis the TIMESTAMPtype. Reference the table
    NEW_CLICK_STREAMinstead of the table CLICK_STREAMfrom now on. In the future, new data is
    loaded into the table NEW_CLICK_STREAM.
  • D. Delete the table CLICK_STREAM, and then re-create it such that the column DTis of the TIMESTAMP
    type. Reload the data.
  • E. Create a view CLICK_STREAM_V, where strings from the column DTare cast into TIMESTAMPvalues.
    Reference the view CLICK_STREAM_Vinstead of the table CLICK_STREAMfrom now on.

Answer: A


NEW QUESTION # 258
MJTelco needs you to create a schema in Google Bigtable that will allow for the historical analysis of the last 2 years of records. Each record that comes in is sent every 15 minutes, and contains a unique identifier of the device and a data record. The most common query is for all the data for a given device for a given day. Which schema should you use?

  • A. Rowkey: date#data_pointColumn data: device_id
  • B. Rowkey: device_idColumn data: date, data_point
  • C. Rowkey: date#device_idColumn data: data_point
  • D. Rowkey: data_pointColumn data: device_id, date
  • E. Rowkey: dateColumn data: device_id, data_point

Answer: D
