Compliance - THE CORRECT ANSWER-Adherence to laws, regulations,
and guidelines that govern data handling and processing.
Structured data - THE CORRECT ANSWER-Data that adheres to a
predefined data model, often used in ETL processes.
Unstructured data - THE CORRECT ANSWER-Data that does not have a
predefined data model, often used in ELT processes.
Semi-structured data - THE CORRECT ANSWER-Data that does not
conform to a rigid structure but has some organizational
properties, often used in ELT processes.
BigQuery - THE CORRECT ANSWER-A Google Cloud service
recommended for post-load transformations in ELT.
Real-time analytics - THE CORRECT ANSWER-The capability to
analyze data as it is created or updated, often favoring ELT.
,Strict data quality checks - THE CORRECT ANSWER-Rigorous
validations performed on data before loading, often
necessitating ETL.
ETL and ELT methodologies - THE CORRECT ANSWER-Google Cloud
offers several services that can be used for both ETL and ELT.
Dataflow - THE CORRECT ANSWER-A versatile tool that can handle
extraction, transformation, and loading tasks depending on
how it is configured.
Cloud Data Fusion - THE CORRECT ANSWER-A versatile tool that can
handle extraction, transformation, and loading tasks depending
on how it is configured.
BigQuery - THE CORRECT ANSWER-Predominantly used for the
transformation step in ELT pipelines after the data has been
loaded, leveraging its SQL-based processing engine.
Google Cloud Storage Transfer Service - THE CORRECT ANSWER-
Provides a fully managed, code-free, and highly scalable service
to automate the transfer of data between various storage
systems.
Key features of Google Cloud Storage Transfer Service - THE
CORRECT ANSWER-Include built-in security with data encryption in
transit and at rest, reliability with data integrity checks, support
for incremental transfers, preservation of object and file
,metadata, centralized job management, and flexible scheduling
options.
Common use cases for Google Cloud Storage Transfer Service -
THE CORRECT ANSWER-Include enabling hybrid and multi-cloud
strategies, optimizing infrastructure costs, completing large-
scale data transfers, implementing disaster recovery and
backup strategies, and enabling analytics and machine learning
workflows.
gcloud storage command - THE CORRECT ANSWER-Suitable for
smaller, ad-hoc transfers, while Storage Transfer Service is
designed for more substantial and automated data movement
scenarios.
Google Cloud Transfer Appliance - THE CORRECT ANSWER-Provides a
secure and efficient offline method for migrating extremely
large datasets, typically petabytes in size, to Google Cloud.
Process of using Google Cloud Transfer Appliance - THE CORRECT
ANSWER-Involves requesting a Transfer Appliance, loading the
data onto the appliance, encrypting the data, securely shipping
the appliance back to Google, where data is uploaded to the
user's Cloud Storage bucket.
Key security features of Google Cloud Transfer Appliance - THE
CORRECT ANSWER-Include a tamper-resistant case, tamper-evident
tags, a Trusted Platform Module (TPM) chip, hardware
attestation, and strong AES 256 encryption.
, Customer-managed encryption keys - THE CORRECT ANSWER-
Supported using Cloud KMS for data at rest and in transit.
Use cases for Google Cloud Transfer Appliance - THE CORRECT
ANSWER-Suitable for migrating extremely large datasets when
network bandwidth is limited or cost-prohibitive.
Transfer Appliance - THE CORRECT ANSWER-Well-suited for use cases
such as collecting large volumes of data from geographically
distributed researchers or vendors, replicating massive datasets
for hybrid cloud architectures, and migrating extensive archives
and backup images to cost-effective Cloud Storage classes.
gcloud storage command - THE CORRECT ANSWER-Provides a
command-line interface for interacting with Google Cloud
Storage, allowing users to perform a wide array of tasks related
to buckets and objects, including uploading and downloading
data.
Common operations of gcloud storage command - THE CORRECT
ANSWER-Besides uploading (cp) and downloading (cp), other
common operations include creating and deleting buckets
(buckets create, buckets delete), listing buckets and objects (ls),
moving and copying objects within Cloud Storage (mv, cp),
renaming objects (mv), and managing access control lists
(ACLs) for buckets and objects.
gsutil - THE CORRECT ANSWER-The original command-line tool for
Google Cloud Storage.
