Question 81

Which of these is NOT a way to customize the software on Dataproc cluster instances?

A.Set initialization actions

B.Modify configuration files using cluster properties

C.Configure the cluster using Cloud Deployment Manager

D.Log into the master node and make changes from there

Question 82

You need to choose a database to store time series CPU and memory usage for millions of computers. You need to store this data in one-second interval samples. Analysts will be performing real-time, ad hoc analytics against the database. You want to avoid being charged for every query executed and ensure that the schema design will allow for future growth of the dataset. Which database and data model should you choose?

A.Create a narrow table in Cloud Bigtable with a row key that combines the Computer Engine computer identifier with the sample time at each second

B.Create a wide table in Cloud Bigtable with a row key that combines the computer identifier with the sample time at each minute, and combine the values for each second as column data.

C.Create a wide table in BigQuery, create a column for the sample value at each second, and update the row with the interval for each second

D.Create a table in BigQuery, and append the new samples for CPU and memory to the table

Question 83

You are working on a sensitive project involving private user dat
a. You have set up a project on Google Cloud Platform to house your work internally. An external consultant is going to assist with coding a complex transformation in a Google Cloud Dataflow pipeline for your project. How should you maintain users' privacy?

A.Grant the consultant the Viewer role on the project.

B.Create a service account and allow the consultant to log on with it.

C.Create an anonymized sample of the data for the consultant to work with in a different project.

D.Grant the consultant the Cloud Dataflow Developer role on the project.

Question 84

You are designing a basket abandonment system for an ecommerce company. The system will send a message to a user based on these rules:
* No interaction by the user on the site for 1 hour
* Has added more than $30 worth of products to the basket
* Has not completed a transaction
You use Google Cloud Dataflow to process the data and decide if a message should be sent. How should you design the pipeline?

A.Use a session window with a gap time duration of 60 minutes.

B.Use a fixed-time window with a duration of 60 minutes.

C.Use a sliding time window with a duration of 60 minutes.

D.Use a global window with a time based trigger with a delay of 60 minutes.

Question 85

Your team is working on a binary classification problem. You have trained a support vector machine (SVM) classifier with default parameters, and received an area under the Curve (AUC) of 0.87 on the validation set.
You want to increase the AUC of the model. What should you do?

A.Perform hyperparameter tuning

B.Train a classifier with deep neural networks, because neural networks would always beat SVMs

C.Deploy the model and measure the real-world AUC; it's always higher because of generalization

D.Scale predictions you get out of the model (tune a scaling factor as a hyperparameter) in order to get the highest AUC
