When HTTP is appropriate for IoT in IOT Protocols - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to show the HTTP method used to send data from an IoT device.

IOT Protocols

device.sendRequest('[1]', url, data)

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

ATRACE

BGET

CCONNECT

DPOST

💡 Hint

Common Mistakes

Using GET instead of POST to send data.

The POST method is used to send data to a server, which is common in IoT devices transmitting sensor data.

2fill in blank

medium

Complete the code to set the HTTP header for content type in an IoT device request.

IOT Protocols

headers = {'Content-Type': '[1]'}

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

Atext/plain

Bimage/png

Capplication/json

Dapplication/xml

💡 Hint

Common Mistakes

Using 'text/plain' instead of 'application/json'.

IoT devices often send data in JSON format, so 'application/json' is the correct content type.

3fill in blank

hard

Fix the error in the code to correctly send an HTTP request from an IoT device.

IOT Protocols

response = device.httpRequest('POST', url, [1]=data)

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

Adata

Bpayload

Cbody

Dcontent

💡 Hint

Common Mistakes

Using 'body' or 'payload' which may cause errors.

The correct parameter name for sending data in many HTTP libraries is 'data'.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that filters IoT sensor data with values above 50.

IOT Protocols

filtered_data = {k: v for k, v in sensor_data.items() if v [1] [2]

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

A>

B50

C<

D100

Attempts:

3 left

💡 Hint

Common Mistakes

Using '<' instead of '>' or wrong threshold value.

The comprehension filters items where the value is greater than 50.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that converts sensor names to uppercase, keeps values, and filters values greater than 20.

IOT Protocols

result = [1]: [2] for [3], [2] in sensors.items() if [2] > 20

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

Ak.upper()

Bv

Ck

Ditems()

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'items()' as a variable or wrong variable names.

The comprehension converts keys to uppercase, keeps values, and filters values greater than 20.
