A company is hosting critical business data in an Amazon Redshift cluster. Due to the sensitive nature of the

A single MySQL database was moved to Amazon Aurora by a business. The production
data is stored in a database cluster in VPC PROD, whereas 12 testing environments are

ensure that each test database has daily production data.
Which migration strategy will be the quickest and least expensive to implement?

A worldwide digital advertising corporation collects browser information in order to provide
targeted visitors with contextually relevant pictures, websites, and connections. A single
page load may create many events, each of which must be kept separately. A single event
may have a maximum size of 200 KB and an average size of 10 KB. Each page load
requires a query of the user's browsing history in order to deliver suggestions for targeted
advertising. The advertising corporation anticipates daily page views of more than 1 billion
from people in the United States, Europe, Hong Kong, and India. The information structure
differs according to the event. Additionally, browsing information must be written and read
with a very low latency to guarantee that consumers have a positive viewing experience.

company runs a report every day to extract customer feedback, and a team reads the

measures. The company wants to use machine learning to automate this workflow.
Which solution meets this requirement with the LEAST amount of effort?

efforts.
