Why data format matters for IoT in IOT Protocols - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the data format used in the IoT message.

IOT Protocols

message_format = "[1]"

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

💡 Hint

Common Mistakes

Choosing XML which is heavier and more complex.

JSON is a common data format for IoT because it is lightweight and easy to read.

medium

Complete the code to parse the incoming IoT data string into a usable format.

IOT Protocols

parsed_data = parse_[1](incoming_message)

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

Axml

Btxt

Cjson

Dcsv

💡 Hint

Common Mistakes

Using xml parser when the data is JSON.

Using json parsing allows the program to convert the JSON string into a data structure.

3fill in blank

hard

Fix the error in the data format declaration to ensure IoT devices understand the message.

IOT Protocols

data_format = '[1]'

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

Ajson

BJson

CJSON

💡 Hint

Common Mistakes

Using capitalized or spaced strings that cause parsing errors.

The data format should be lowercase 'json' without extra spaces for consistency and compatibility.

4fill in blank

hard

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

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>

B10

C<

D5

💡 Hint

Common Mistakes

Using '<' instead of '>' causing wrong filtering.

The comprehension filters sensor data where values are greater than 10.

5fill in blank

hard

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

IOT Protocols

processed_data = { [1]: [2] for [3], [2] in raw_data.items() if [2] > 20 }

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

Ak.upper()

💡 Hint

Common Mistakes

Using wrong variable names or forgetting to transform keys.

This comprehension changes keys to uppercase, keeps values, and filters values greater than 20.
