1. You are developing an application that will only recognize and tag specific business to
business product logos in images. You do not have an extensive background working
with machine learning models, but need to get your application working. What is the
current best method to accomplish this task? - (answer)a. Use the AutoML Vision service
to train a custom model using the Vision API
i. The newly added AutoML services allow you to train custom image (and other models)
using the Google's pre-trained API's as a base. Training a custom model also works on
AI Platform, but this route requires less manual model overhead.
2. Your organization is streaming telemetry data into BigQuery for long-term storage (2
years) and analysis, at the rate of about 100 million records per day. They need to be
able to run queries against certain time periods of data without incurring the costs of
querying all available records. What is the preferred method for doing so? - (answer)a.
Partition a single table by day, and run queries against individual partitions.
i. Partitioning a single table by date allows you to maintain a single table, but also be
able to run queries on a smaller portion of it. While using wildcards across multiple
tables (one for each day) technically works, partitioning a single table is best practice.
3. You are an administrator for several organizations in the same company. Each
organization has data in their own BigQuery table within a single project. For application
access reasons, all of the tables must remain in the same project. You think each
organization should be able to view and run queries against their own data without
exposing the data of organizations to unauthorized viewers. What should you
recommend? - (answer)a. Create a separate dataset for each organization in the same
project. Place each organization's table in each dataset. Restrict access to the
organization's dataset to only that company, from which they can view their table but
no one else's.
i. You can assign roles at the dataset level. Placing tables in different datasets allows you
to limit access per dataset.

4. Your company is making the move to Google Cloud and has chosen to use a
managed database service to reduce overhead. Your existing database is used for a
product catalog that provides real-time inventory tracking for a retailer. Your database is
500 GB in size. The data is semi-structured and does not need full atomicity. You are
looking for a truly no-ops/serverless solution. What storage option should you choose?
- (answer)a. Cloud Datastore
i. Datastore is perfect for semi-structured data less than 1TB in size. Product catalogs are
a recommended use case.
5. How can you set up your Dataproc environment to use BigQuery as an input and
output source? - (answer)a. Install the BigQuery connector on your Dataproc cluster.
i. You can install the BigQuery connector to your cluster for direct programmatic
read/write access to BigQuery. Note that a Cloud Storage bucket is used between the
two services, but you'll interact directly with BigQuery from Dataproc.
6. In AI Platform, what does the CUSTOM tier allow you to configure? Choose the best
answer. - (answer)a. Custom number of workers and parameter servers. Machine type of
master server
i. Correct. You can customize the number of workers and parameter servers, but masters
are set to one.
7. You are building a data pipeline on Google Cloud. You need to prepare source data
for a machine-learning model. This involves quickly deduplicating rows from three input
tables and also removing outliers from data columns where you do not know the data
distribution. What should you do? - (answer)a. Use Cloud Dataprep to preview the data
distributions in sample source data table columns. Click on each column name, click on
each appropriate suggested transformation, and then click Add to add each
transformation to the Cloud Dataprep job.

i. Dataprep is the correct choice because of the requirements to prepare/clean source
data. For deduplication, using the suggestion transformation would be easier and
quicker than writing a recipe, which is more work than needed.
8. As part of your backup plan, you create regular boot-disk snapshots of Compute
Engine instances that are running. You want to be able to restore these snapshots using
the fewest possible steps for replacement instances. What should you do? - (answer)a.
Use the snapshots to create replacement instances as needed.
i. Snapshots let you recreate instances in the fewest steps.
9. You are setting up multiple MySQL databases on Compute Engine. You need to
collect logs from your MySQL applications for audit purposes. How should you
approach this? - (answer)a. Install the Stackdriver Logging agent on your database
instances and configure the fluentd plugin to read and export your MySQL logs into
Stackdriver Logging.
i. The Stackdriver Logging agent requires the fluentd plugin to be configured to read
logs from your database application.
10. Which of these statements do not apply to preemptible worker nodes on Cloud
Dataproc? Choose two answers. - (answer)a. You must have a max of 2:1 ratio of
preemptible to standard workers.
i. There is no ratio requirement, but be aware that preemptible workers can be reclaimed
at any time, and you will want a number of standard workers that are always persistent.
b. Your cluster can be created with only preemptible workers
i. You must have at least one standard worker in a cluster.
11. You need to deploy a TensorFlow machine-learning model to Google Cloud. You
want to maximize the speed and minimize the cost of model prediction and
