Explanation:

Develop, deploy, protect and monitor your APIs with Google Cloud Endpoints. Using an Open API Specification or one of our API frameworks, Cloud

Endpoints gives you the tools you need for every phase of API development.

From scenario:

Business Requirements

Decrease unplanned vehicle downtime to less than 1 week, without increasing the cost of carrying surplus inventory

Support the dealer network with more data on how their customers use their equipment to better position new

products and services

Have the ability to partner with different companies especially with seed and fertilizer suppliers in the fast- growing agricultural business to create compelling

joint offerings for their customers.

Cloud Platform APIs support OAuth 2.0, and scopes provide granular authorization over the methods that are supported. Cloud Platform supports both

service-account and user-account OAuth, also called three-legged OAuth.

QUESTION 31

You analyzed TerramEarth's business requirement to reduce downtime, and found that they can achieve a majority of time saving by reducing customer's

wait time for parts. You decided to focus on reduction of the 3 weeks aggregate reporting time.

Which modifications to the company's processes should you recommend?

Migrate from CSV to binary format, migrate from FTP to SFTP transport, and develop machine learning analysis of metrics

Migrate from FTP to streaming transport, migrate from CSV to binary format, and develop machine learning analysis of metrics

Increase fleet cellular connectivity to 80%, migrate from FTP to streaming transport, and develop machine learning analysis of metrics

Explanation:

The Avro binary format is the preferred format for loading compressed data. Avro data is faster to load because the data can be read in parallel, even when

the data blocks are compressed. Cloud Storage supports streaming transfers with the gsutil tool or boto library, based on HTTP chunked transfer encoding.

Streaming data lets you stream data to and from your Cloud Storage account as soon as it becomes available without requiring that the data be first saved to

a separate file. Streaming transfers are useful if you have a process that generates data and you do not want to buffer it locally before uploading it, or if you

want to send the result from a computational pipeline directly into Cloud Storage.

QUESTION 33

To speed up data retrieval, more vehicles will be upgraded to cellular connections and be able to transmit data to the ETL process. The current FTP process

is error-prone and restarts the data transfer from the start of the file when connections fail, which happens often. You want to improve the reliability of the

solution and minimize data transfer time on the cellular connections.

What should you do?

Use one Google Container Engine cluster of FTP servers. Save the data to a Multi-Regional bucket. Run the ETL process using data in the bucket

Use multiple Google Container Engine clusters running FTP servers located in different regions. Save the data to Multi-Regional buckets in US, EU, and

Asia. Run the ETL process using the data in the bucket

Directly transfer the files to different Google Cloud Multi-Regional Storage bucket locations in US, EU, and Asia using Google APIs over HTTP(S). Run

the ETL process using the data in the bucket

Directly transfer the files to a different Google Cloud Regional Storage bucket location in US, EU, and Asia using Google APIs over HTTP(S). Run the

QUESTION 34

TerramEarth's 20 million vehicles are scattered around the world. Based on the vehicle's location, its telemetry data is stored in a Google Cloud Storage

(GCS) regional bucket (US, Europe, or Asia). The CTO has asked you to run a report on the raw telemetry data to determine why vehicles are breaking down

after 100 K miles.

You want to run this job on all the data.

What is the most

cost-effective way to run this job?

Move all the data into 1 zone, then launch a Cloud Dataproc cluster to run the job

Move all the data into 1 region, then launch a Google Cloud Dataproc cluster to run the job

Launch a cluster in each region to preprocess and compress the raw data, then move the data into a multi- region bucket and use a Dataproc cluster to

finish the job

QUESTION 35

TerramEarth has equipped all connected trucks with servers and sensors to collect telemetry data. Next year they want to use the data to train machine

learning models. They want to store this data in the cloud while reducing costs.

What should they do?

Have the vehicle's computer compress the data in hourly snapshots, and store it in a Google Cloud Storage (GCS) Nearline bucket

Push the telemetry data in real-time to a streaming dataflow job that compresses the data, and store it in Google BigQuery

Push the telemetry data in real-time to a streaming dataflow job that compresses the data, and store it in Cloud Bigtable

Have the vehicle's computer compress the data in hourly snapshots, and store it in a GCS Coldline bucket

Correct Answer: D

Explanation

Explanation/Reference:

Explanation:

Storage is the best choice for data that you plan to access at most once a year, due to its slightly lower availability, 90-day minimum storage duration, costs

for data access, and higher per-operation costs. For example:

Cold Data Storage - Infrequently accessed data, such as data stored for legal or regulatory reasons, can be stored at low cost as Coldline Storage, and be

available when you need it.

Disaster recovery - In the event of a disaster recovery event, recovery time is key. Cloud Storage provides low latency access to data stored as Coldline

Storage.

QUESTION 37

Operational parameters such as oil pressure are adjustable on each of TerramEarth's vehicles to increase their efficiency, depending on their environmental

conditions. Your primary goal is to increase the operating efficiency of all 20 million cellular and unconnected vehicles in the field.

How can you accomplish this goal?

Have you engineers inspect the data for patterns, and then create an algorithm with rules that make operational adjustments automatically

Capture all operating data, train machine learning models that identify ideal operations, and run locally to make operational adjustments automatically
