Why security protects deployed IoT devices in Raspberry Pi - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to print a message confirming the device is secure.

Raspberry Pi

print("Device security status: [1]")

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

Bsecured

Coffline

Dvulnerable

💡 Hint

Common Mistakes

Using 'vulnerable' or 'offline' which indicate insecurity or no connection.

The device should report 'secured' to confirm it is protected.

2fill in blank

medium

Complete the code to check if the device is connected to a secure network.

Raspberry Pi

if network_status == '[1]':
    print("Network is secure")

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

Auntrusted

Bdisconnected

Csecure

Dunknown

💡 Hint

Common Mistakes

Using 'disconnected' or 'untrusted' which do not mean secure.

The condition should check for 'secure' to confirm network safety.

3fill in blank

hard

Fix the error in the code that checks device authentication.

Raspberry Pi

if device.authenticated [1] True:
    print("Access granted")

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

B=

C!=

D=>

💡 Hint

Common Mistakes

Using '=' instead of '==' causes syntax errors.

Use '==' to compare values in a condition, '=' is assignment and causes error.

4fill in blank

hard

Fill both blanks to create a dictionary of device statuses for devices with battery level above 20.

Raspberry Pi

device_status = {device_id: status for device_id, status in devices.items() if status['[1]'] > 20 and status['[2]'] == 'active'}

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

Abattery_level

Bsignal_strength

Cstatus

Ddevice_id

💡 Hint

Common Mistakes

Using 'signal_strength' or 'device_id' in conditions which are incorrect.

We check 'battery_level' > 20 and 'status' == 'active' to filter devices.

5fill in blank

hard

Fill all three blanks to create a dictionary of device names in uppercase for devices with signal above 50 and status 'online'.

Raspberry Pi

device_names = { [1]: [2].upper() for [3], info in devices.items() if info['signal'] > 50 and info['status'] == 'online'}

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

Aname.upper()

Binfo['name']

Cdevice_id

Dname

💡 Hint

Common Mistakes

Mixing up keys and values or using wrong variable names.

We use device_id as key, info['name'].upper() as value, and iterate with device_id, info.
