Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the protocol used by AWS IoT Core for device communication.

IOT Protocols

protocol = "[1]"

Drag options to blanks, or click blank then click option'

AHTTP

BMQTT

CFTP

DSMTP

💡 Hint

Common Mistakes

Choosing HTTP which is heavier than MQTT for IoT devices.

AWS IoT Core primarily uses MQTT protocol for lightweight, efficient device communication.

2fill in blank

medium

Complete the code to define the AWS IoT Core service component that manages device identities and credentials.

IOT Protocols

identity_service = "[1]"

Drag options to blanks, or click blank then click option'

AAmazon S3

BAWS CloudTrail

CAWS IoT Device Registry

DAWS Lambda

💡 Hint

Common Mistakes

Confusing with AWS Lambda which runs code, not manages device identities.

The AWS IoT Device Registry stores and manages device identities and credentials securely.

3fill in blank

hard

Fix the error in the code to correctly represent the AWS IoT Core component that routes messages between devices and AWS services.

IOT Protocols

message_router = "[1]"

Drag options to blanks, or click blank then click option'

AAWS IoT Rules Engine

BAWS IoT Analytics

CAWS IoT Greengrass

DAWS IoT Device Defender

💡 Hint

Common Mistakes

Choosing AWS IoT Analytics which analyzes data but does not route messages.

The AWS IoT Rules Engine routes and transforms messages from devices to other AWS services.

4fill in blank

hard

Fill both blanks to complete the code that defines the AWS IoT Core feature for secure device communication and the protocol it supports.

IOT Protocols

security_feature = "[1]"
protocol_supported = "[2]"

Drag options to blanks, or click blank then click option'

AMutual TLS

BOAuth

CMQTT

DHTTP

💡 Hint

Common Mistakes

Confusing OAuth with Mutual TLS for device authentication.

AWS IoT Core uses Mutual TLS for secure communication and supports MQTT protocol for messaging.

5fill in blank

hard

Fill all three blanks to complete the code that sets up an AWS IoT Core rule to send device data to a storage service using the correct SQL statement and target service.

IOT Protocols

rule_sql = "SELECT [1] FROM '[2]'"
target_service = "[3]"

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using incorrect topic name or target service like IoT Analytics instead of S3.

The SQL statement selects all data (*) from the device data topic, and the target service is Amazon S3 for storage.
