AWS Big Data Quiz

A web application emits multiple types of events to Amazon Kinesis Streams for operational reporting.

Critical events must be captured immediately before processing can continue,but informational events

do not need to delay processing.

What is the most appropriate solution to record these different types of events?

• Log all events using the Kinesis Producer Library

• Log critical events using the Kinesis Producer Library and log informational events using the PutRecords API method

• Log critical events using the PutRecords API method and log informational events using the Kinesis Producer Library

• Log all events using the PutRecords API method

A company needs to deploy a data lake solution for their data scientists in which all company data is accessible and stored in a central S3 bucket. The company segregates the data by business unit,using specific prefixes. Scientists can only access the data from their own business unit. The company needs a single sign-on identity and management solution based on Microsoft Active Directory (AD) to manage access to the data in Amazon S3.Which method meets these requirements?

• Use AWS IAM Federation functions and specify the associated

  role based on the users' groups in AD.

• Create bucket policies that only allow access

  to the authorized prefixes based on the users' group name

  in Active Directory

• Deploy the AD Synchronization service to create AWS IAM

  users and groups based on AD information

• Use Amazon S3 API integration with AD to impersonate the users on access in a transparent manner

An organization needs a data store to handle the following data types and access patterns:

1.Key value access pattern

2.Complex SQL queries and transactions

3.Consistent reads

4.Fixed schema

Which data store should the organization choose?

• Amazon S3

• Amazon Kinesis

• Amazon DynamoDB

• Amazon RDS

A mobile application collects data that must be stored in multiple Availability Zones within five minutes

of being captured in the app. What architecture securely meets these requirements?

• The mobile app should write to an S3 bucket that allows anonymous PutObject calls

• The mobile app should authenticate with an Amazon Cognito identity that is authorized to write to an Amazon Kinesis Firehose

  with an Amazon S3 destination

  .

• The mobile app should authenticate with an embedded IAM access key that is authorized to write to an Amazon Kinesis Firehose

  with an Amazon S3 destination

• The mobile app should call a REST-based service that stores data on Amazon EBS. Deploy the serviceon multiple EC2 instances across two Availability Zones.
