easy

Complete the code to enable DynamoDB Streams on a table.

💡 Hint

Common Mistakes

Using string values like 'Enabled' instead of boolean true.

To enable DynamoDB Streams, the StreamEnabled parameter must be set to true.

2fill in blank

medium

Complete the code to specify the stream view type when enabling DynamoDB Streams.

AWS

aws dynamodb update-table --table-name MyTable --stream-specification StreamViewType=[1]

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

💡 Hint

Common Mistakes

Choosing FULL_IMAGE which captures all attributes, not just keys.

The StreamViewType defines what information the stream captures. KEYS_ONLY captures only the primary key attributes.

3fill in blank

Fix the error in the AWS CLI command to describe the latest stream ARN for a DynamoDB table.

AWS

aws dynamodb describe-table --table-name [1]

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

ATableName

BMyStream

CMyTable

DStreamARN

Attempts:

💡 Hint

Common Mistakes

Using the stream ARN instead of the table name.

The describe-table command requires the table name, not the stream name or ARN.

4fill in blank

hard

Fill both blanks to create a Python snippet that reads records from a DynamoDB stream using boto3.

AWS

response = client.get_records(ShardIterator=[1], Limit=[2])

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

A'shard_iterator_value'

B100

C200

D'iterator_value'

Attempts:

💡 Hint

Common Mistakes

Using an integer for ShardIterator or a string for Limit.

The ShardIterator must be a string token, and Limit is an integer specifying max records.

5fill in blank

hard

Fill all three blanks to configure a DynamoDB stream with NEW_IMAGE view and enable it using AWS CLI.

AWS

aws dynamodb update-table --table-name [1] --stream-specification StreamEnabled=[2],StreamViewType=[3]

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

AMyTable

Btrue

CNEW_IMAGE

Dfalse

Attempts:

3 left

💡 Hint

Common Mistakes

Disabling the stream or using incorrect view types.

To enable streams with NEW_IMAGE view, set StreamEnabled to true and StreamViewType to NEW_IMAGE for the correct table.
