What are the two most likely causes of this problem? Choose 2 answers.

A : blisher throughput quota is too small.

B : tal outstanding messages exceed the 10-MB maximum.

C : ror handling in the subscriber code is not handling run-time errors properly.

D : subscriber code cannot keep up with the messages.

E : subscriber code does not acknowledge the messages that it pulls.

Answer: C,D

Question 2

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 : zone

B : number of workers

C : disk size per worker

D : maximum number of workers

Answer: A

Question 3

Why do you need to split a machine learning dataset into training data and test data?

A : you can try two different sets of features

B : make sure your model is generalized for more than just the training data

C : allow you to create unit tests in your code

D : you can use one dataset for a wide model and one for a deep model

Answer: B

Question 4

You are developing an Apache Beam pipeline to extract data from a Cloud SQL instance by using JdbclO.

You have two projects running in Google Cloud. The pipeline will be deployed and executed on Dataflow in

Project A. The Cloud SQL instance is running jn Project B and does not have a public IP address. After

deploying the pipeline, you noticed that the pipeline failed to extract data from the Cloud SQL instance due to

connection failure. You verified that VPC Service Controls and shared VPC are not in use in these projects.

You want to resolve this error while ensuring that the data does not go through the public internet. What

should you do?

A : Set up VPC Network Peering between Project A and Project B. Add a firewall rule to allow the peeredsubnet range to access all instances on the network.

B : Turn off the external IP addresses on the Dataflow worker. Enable Cloud NAT in Project A.

C : Set up VPC Network Peering between Project A and Project B. Create a Compute Engine instance without external IP address in Project B on the peered subnet to serve as a proxy server to the Cloud SQL database.

D : Add the external IP addresses of the Dataflow worker as authorized networks in the Cloud SOL instance.

Answer: C

Question 5

You want to use Google Stackdriver Logging to monitor Google BigQuery usage. You need an instant notification to be sent to your monitoring tool when new data is appended to a certain table using an insert job, but you do not want to receive notifications for other tables. What should you do?

A : ke a call to the Stackdriver API to list all logs, and apply an advanced filter.

B : the Stackdriver logging admin interface, and enable a log sink export to BigQuery.

C : the Stackdriver logging admin interface, enable a log sink export to Google Cloud Pub/Sub, and subscribe to the topic from your monitoring tool.

D : ing the Stackdriver API, create a project sink with advanced log filter to export to Pub/Sub, and subscribe to the topic from your monitoring tool.
