Overview

In a challenge lab you’re given a scenario and a set of tasks. Instead of following step-by-step instructions, you will use the skills learned from the labs in the quest to figure out how to complete the tasks on your own! An automated scoring system (shown on this page) will provide feedback on whether you have completed your tasks correctly.

When you take a challenge lab, you will not be taught new Google Cloud concepts. You are expected to extend your learned skills, like changing default values and reading and researching error messages to fix your own mistakes.

To score 100% you must successfully complete all tasks within the time period!

This lab is recommended for students who have enrolled in the Perform Foundational Data, ML, and AI Tasks in Google Cloud quest. Are you ready for the challenge?

Topics tested:

• Create a simple Dataproc job
• Create a simple DataFlow job
• Create a simple Dataprep job
• Perform one of the three Google machine learning backed API tasks

Setup

Before you click the Start Lab button

Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources will be made available to you.

This hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials that you use to sign in and access Google Cloud for the duration of the lab.

To complete this lab, you need:

• Access to a standard internet browser (Chrome browser recommended).

Note: Use an Incognito or private browser window to run this lab. This prevents any conflicts between your personal account and the Student account, which may cause extra charges incurred to your personal account.

• Time to complete the lab---remember, once you start, you cannot pause a lab.

Note: If you already have your own personal Google Cloud account or project, do not use it for this lab to avoid extra charges to your account.

How to start your lab and sign in to the Google Cloud Console

1. Click the Start Lab button. If you need to pay for the lab, a pop-up opens for you to select your payment method. On the left is the Lab Details panel with the following:

   • The Open Google Console button
   • Time remaining
   • The temporary credentials that you must use for this lab
   • Other information, if needed, to step through this lab

2. Click Open Google Console. The lab spins up resources, and then opens another tab that shows the Sign in page.

   Tip: Arrange the tabs in separate windows, side-by-side.

   Note: If you see the Choose an account dialog, click Use Another Account.

3. If necessary, copy the Username from the Lab Details panel and paste it into the Sign in dialog. Click Next.

4. Copy the Password from the Lab Details panel and paste it into the Welcome dialog. Click Next.

   Important: You must use the credentials from the left panel. Do not use your Google Cloud Skills Boost credentials. Note: Using your own Google Cloud account for this lab may incur extra charges.

5. Click through the subsequent pages:

   • Accept the terms and conditions.
   • Do not add recovery options or two-factor authentication (because this is a temporary account).
   • Do not sign up for free trials.

After a few moments, the Cloud Console opens in this tab.

Note: You can view the menu with a list of Google Cloud Products and Services by clicking the Navigation menu at the top-left.

Challenge scenario

As a junior data engineer in Jooli Inc. and recently trained with Google Cloud and a number of data services you have been asked to demonstrate your newly learned skills. The team has asked you to complete the following tasks.

You are expected to have the skills and knowledge for these tasks so don’t expect step-by-step guides.

Task 1: Run a simple Dataflow job

You have used Dataflow in the quest to load data into BigQuery from Pub/Sub, now use the Dataflow batch template Text Files on Cloud Storage to BigQuery under "Process Data in Bulk (batch)" to transfer data from a Cloud Storage bucket (gs://cloud-training/gsp323/lab.csv). The following table has the values you need to correctly configure the Dataflow job.

You will need to make sure you have:

• Create a BigQuery dataset called .
• Create a Cloud Storage Bucket called .

Field	Value
JavaScript UDF path in Cloud Storage	gs://cloud-training/gsp323/lab.js
JSON path	gs://cloud-training/gsp323/lab.schema
JavaScript UDF name	transform
BigQuery output table
Cloud Storage input path	gs://cloud-training/gsp323/lab.csv
Temporary BigQuery directory
Temporary location

Wait for the job to finish before trying to check your progress.

Click Check my progress to verify the objective. Run a simple Dataflow job

Task 2: Run a simple Dataproc job

You have used Dataproc in the quest, now you must run another example Spark job using Dataproc.

Before you run the job, log into one of the cluster nodes and copy the /data.txt file into hdfs (use the command hdfs dfs -cp gs://cloud-training/gsp323/data.txt /data.txt).

Run a Dataproc job using the values below.

Field	Value
Region
Job type	Spark
Main class or jar	org.apache.spark.examples.SparkPageRank
Jar files	file:///usr/lib/spark/examples/jars/spark-examples.jar
Arguments	/data.txt
Max restarts per hour	1

Wait for the job to finish before trying to check your progress.

Task 3: Run a simple Dataprep job

You have used Dataprep to import data files and transformed them to gain views of the data. Use Dataprep to import one CSV file (described below) that holds data of lab executions.

gs://cloud-training/gsp323/runs.csv structure:

runid	userid	labid	lab_title	start	end	time	score	state
5556	545	122	Lab 122	2020-04-09 16:18:19	2020-04-09 17:10:11	3112	61.25	SUCCESS
5557	116	165	Lab 165	2020-04-09 16:44:45	2020-04-09 18:13:58	5353	60.5	SUCCESS
5558	969	31	Lab 31	2020-04-09 17:59:01	2020-04-09 18:02:09	188	0	FAILURE

Perform the following transforms to ensure the data is in the right state:

• Remove all rows with the state of "FAILURE"
• Remove all rows with 0 or 0.0 as a score (Use the regex pattern /(^0$|^0\.0$)/)
• Label columns with the names above

Note: Your Dataprep job should look similar to the following:

Make sure you run the job. You will need to wait until the Dataflow job completes before you can grade this task.

Task 4: AI

Complete one of the following tasks below.

• Use Google Cloud Speech API to analyze the audio file gs://cloud-training/gsp323/task4.flac. Once you have analyzed the file you can upload the resulting analysis to .

• Use the Cloud Natural Language API to analyze the sentence from text about Odin. The text you need to analyze is "Old Norse texts portray Odin as one-eyed and long-bearded, frequently wielding a spear named Gungnir and wearing a cloak and a broad hat." Once you have analyzed the text you can upload the resulting analysis to .

• Use Google Video Intelligence and detect all text on the video gs://spls/gsp154/video/train.mp4. Once you have completed the processing of the video, pipe the output into a file and upload to . Ensure the progress of the operation is complete and the service account you're uploading the output with has the Storage Object Admin role.

Note: If you are facing issues in any of the above task you can refer the respective labs for troubleshooting:

1. Google Cloud Speech API: Qwik Start
2. Cloud Natural Language API: Qwik Start
3. Video Intelligence: Qwik Start
