Question 1

You are designing storage for very large text files for a data pipeline on Google Cloud. You want to support ANSI SQL queries. You also want to support compression and parallel load from the input locations using Google recommended practices. What should you do?

A : ansform text files to compressed Avro using Cloud Dataflow. Use BigQuery for storage and query.

B : ansform text files to compressed Avro using Cloud Dataflow. Use Cloud Storage and BigQuery permanent linked tables for query.

C : mpress text files to gzip using the Grid Computing Tools. Use BigQuery for storage and query.

D : mpress text files to gzip using the Grid Computing Tools. Use Cloud Storage, and then import into Cloud Bigtable for query.

Answer: D

Question 2

You want to archive data in Cloud Storage. Because some data is very sensitive, you want to use the “Trust No One” (TNO) approach to encrypt your data to prevent the cloud provider staff from decrypting your data. What should you do?

A : gcloud kms keys create to create a symmetric key. Then use gcloud kms encrypt to encrypt each archival file with the key and unique additional authenticated data (AAD). Use gsutil cp to upload each encrypted file to the Cloud Storage bucket, and keep the AAD outside of Google Cloud.

B : gcloud kms keys create to create a symmetric key. Then use gcloud kms encrypt to encrypt each archival file with the key. Use gsutil cp to upload each encrypted file to the Cloud Storage bucket. Manually destroy the key previously used for encryption, and rotate the key once and rotate the key once.

C : ecify customer-supplied encryption key (CSEK) in the .boto configuration file. Use gsutil cp to upload each archival file to the Cloud Storage bucket. Save the CSEK in Cloud Memorystore as permanent storage of the secret.

D : ecify customer-supplied encryption key (CSEK) in the .boto configuration file. Use gsutil cp to upload each archival file to the Cloud Storage bucket. Save the CSEK in a different project that only the security team can access.

Answer: B

Question 3

Your software uses a simple JSON format for all messages. These messages are published to Google Cloud Pub/Sub, then processed with Google Cloud Dataflow to create a real-time dashboard for the CFO. During testing, you notice that some messages are missing in the dashboard. You check the logs, and all messages are being published to Cloud Pub/Sub successfully. What should you do next?

A : eck the dashboard application to see if it is not displaying correctly.

B : n a fixed dataset through the Cloud Dataflow pipeline and analyze the output.

C : Google Stackdriver Monitoring on Cloud Pub/Sub to find the missing messages.

D : itch Cloud Dataflow to pull messages from Cloud Pub/Sub instead of Cloud Pub/Sub pushing messages to Cloud Dataflow.

Answer: B

Question 4

Your company maintains a hybrid deployment with GCP, where analytics are performed on your anonymized customer data. The data are imported to Cloud Storage from your data center through parallel uploads to a data transfer server running on GCP. Management informs you that the daily transfers take too long and have asked you to fix the problem. You want to maximize transfer speeds. Which action should you take?

A : crease the CPU size on your server.

B : crease the size of the Google Persistent Disk on your server.

C : crease your network bandwidth from your datacenter to GCP.

D : crease your network bandwidth from Compute Engine to Cloud Storage.

Answer: C

Question 5

Which methods can be used to reduce the number of rows processed by BigQuery?

A : litting tables into multiple tables; putting data in partitions

B : litting tables into multiple tables; putting data in partitions; using the LIMIT clause

C : tting data in partitions; using the LIMIT clause

D : litting tables into multiple tables; using the LIMIT clause

Answer: A
