easy

Complete the code to specify the S3 bucket name for export.

DynamoDB

export_task = dynamodb.export_table_to_point_in_time(
    TableArn='arn:aws:dynamodb:us-west-2:123456789012:table/Books',
    S3Bucket=[1]
)

💡 Hint

Common Mistakes

Using an incorrect or non-existent bucket name.

Forgetting to put the bucket name in quotes.

The S3Bucket parameter must be the name of the S3 bucket where the export will be stored. Here, 'dynamodb-exports' is the correct bucket name used in this example.

Complete the code to specify the export format as DynamoDB JSON.

DynamoDB

export_task = dynamodb.export_table_to_point_in_time(
    TableArn='arn:aws:dynamodb:us-west-2:123456789012:table/Books',
    S3Bucket='dynamodb-exports',
    ExportFormat=[1]
)

D'JSON'

💡 Hint

Common Mistakes

Using 'JSON' instead of 'DYNAMODB_JSON'.

Using unsupported formats like 'CSV' for DynamoDB export.

The ExportFormat parameter defines the format of the exported data. 'DYNAMODB_JSON' is the correct format for DynamoDB JSON export.

Fix the error in the export code by completing the missing parameter for export time.

DynamoDB

export_task = dynamodb.export_table_to_point_in_time(
    TableArn='arn:aws:dynamodb:us-west-2:123456789012:table/Books',
    S3Bucket='dynamodb-exports',
    ExportFormat='DYNAMODB_JSON',
    ExportTime=[1]
)

💡 Hint

Common Mistakes

Passing a string instead of a datetime object.

Using incorrect functions like 'now()' as a string.

The ExportTime parameter expects a datetime object representing the point in time to export. Using datetime.datetime.now() provides the current time in the correct format.

4fill in blank

hard

Fill both blanks to create an export task with the correct table ARN and S3 prefix.

DynamoDB

export_task = dynamodb.export_table_to_point_in_time(
    TableArn=[1],
    S3Bucket='dynamodb-exports',
    S3Prefix=[2],
    ExportFormat='DYNAMODB_JSON'
)

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

A'arn:aws:dynamodb:us-west-2:123456789012:table/Orders'

B'exports/orders'

C'arn:aws:dynamodb:us-west-2:123456789012:table/Customers'

D'exports/customers'

💡 Hint

Common Mistakes

Mixing table ARNs and prefixes incorrectly.

Using prefixes without quotes.

The TableArn must be the ARN of the table you want to export. The S3Prefix is the folder path inside the bucket where the export files will be stored.

5fill in blank

hard

Fill all three blanks to complete the export task with table ARN, S3 bucket, and export format.

DynamoDB

export_task = dynamodb.export_table_to_point_in_time(
    TableArn=[1],
    S3Bucket=[2],
    ExportFormat=[3]
)

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

A'arn:aws:dynamodb:us-west-2:123456789012:table/Inventory'

B'dynamodb-exports'

C'DYNAMODB_JSON'

D'arn:aws:dynamodb:us-west-2:123456789012:table/Sales'

Attempts:

💡 Hint

Common Mistakes

Using wrong ARNs or bucket names.

Confusing export format strings.

To export a DynamoDB table, you need to provide the table ARN, the S3 bucket name, and the export format. Here, the correct values are the Inventory table ARN, the bucket 'dynamodb-exports', and the format 'DYNAMODB_JSON'.
