Adaface Sample Django Questions

Review the following sample Django URL.conf:

Pick the correct statements if settings.APPEND_SLASH=False:
            
            A: A request to /books/2015/04/ would match the third entry in the list. Django would call the function views.month_books(request, year=2015, month=4).
            B: A request to /books/2015/04/ would match the second entry in the list. Django would call the function views.year_books(request, year=2015).
            
            C: A request to /books/2023/ will match the first entry in the list. Django would call the the function views.custom_newyear_2023(request).
            D: A request to /books/2023/ would match the second entry in the list. Django would call the function views.year_books(request, year=2023).
            
            E: /books/2022 would not match any of these patterns, because each pattern requires that the URL end with a slash.
            F: A request to /books/2022 would match the second entry in the list. Django would call the function views.year_books(request, year=2022).

Review the following Django code for a banking application:

The code needs to debit an account with the provided amount and deposit the amount in an external entity. Here’s how the code is broken:
            
            1) First, the amount is debited from the account by creating a new row in BalanceLine table.
            2) Next, a new row is created in the DB in ExternalTransfer table and a new id (used as unique reference) is created for the transfer.
            3) An external 3rd party API call is made using the new id created in step 2.
            
            The function transfer_to_other_bank is called as shown below:

Pick the correct statements:
            
            A: If post_transfer_emails() raises an exception, the database transactions that happened in transfer_to_other_bank are not rolled back since they are listed in a separate atomic transaction.
            B: If post_transfer_emails() raises an exception, the database transactions (new rows in ExternalTransfer and BalanceLine tables) are rolled back. The banking_api call is called again with a null reference.
            C: If post_transfer_emails() raises an exception, the database transactions are rolled back but the banking_api is not called again.
            D: If post_transfer_emails() raises an exception, the banking_api is called again with rollback=True. If the response is success, then the database transactions are rolled back. If the response is failure, the database transactions are committed.
