Module quiz: Securing an API in Django REST framework Quiz Answers

Question 1)
In what way can you validate the price field to not be less than 5 in a serializer? Choose all that apply.

• By using a validation method
• By using a validate_price_lt method

By adding this line of code in the serializer:

• price = serializers.DecimalField(max_digits=6, decimal_places=2, min_value=5)

By adding

• ‘price’: {‘min_value’: 2} in the extra_kwargs section
• By using a validate method

Question 2)
How can you limit an API endpoint in such a way that only POST, PUT, PATCH and DELETE calls will be throttled, but GET calls will not be throttled? Choose all that apply.

• This cannot be done
• By writing a scoped throttle class and set it up in the settings.py file
• By writing a custom throttle class and overriding the get_throttles method
• By writing a custom throttle class and using it inside a @throttle_classes decorator.

Question 3)
For token-based authentication, you need to install the Djoser library because DRF doesn’t support such authentications by default.

• True
• False

Question 4)
How can you enable support for sorting the API output by two fields: age and gender?

• By manually parsing the query string
• By adding this line of code
• ordering_fields=[‘age’,’gender’] in a class-based view
• By adding this @ordering_fields([‘age’,’gender’]) above a function-based view
• No code change is required. Just add ‘OrderingFilter’ in the settings.py file and DRF will process it automatically.

• /user/confirm/
• /user/

• From the Django admin panel

Question 8)
Which of the following prefixes should you use to successfully authenticate a token using SimpleJWT library?

• Auth Token
• Bearer
• Auth
• Token

Question 9)
What happens when you blacklist a JWT refresh token?

• It also blacklists the access token
• It cannot be used to generate new access tokens anymore.
• It expires
• It blocks the user who bears this token
• It cannot be used to generate new refresh tokens
