💡 Hint

Common Mistakes

Using reserved words like 'CreateTable' as the table name.

Leaving the table name empty or misspelled.

The TableName parameter sets the name of the DynamoDB table. Here, 'Users' is a valid table name.

Complete the code to define the primary key attribute name for the DynamoDB table.

DynamoDB

"AttributeName": "[1]",

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

BUserId

CKeyName

DId

💡 Hint

Common Mistakes

Using generic names like 'Id' without context.

Using names that don't match the key schema.

The AttributeName defines the name of the primary key attribute. 'UserId' is a common choice for user tables.

Fix the error in the key schema by completing the code with the correct key type.

DynamoDB

"KeyType": "[1]"

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

💡 Hint

Common Mistakes

Using 'PRIMARY' or 'KEY' which are not valid DynamoDB key types.

Confusing 'HASH' with 'SORT' when only one key is defined.

The KeyType must be 'HASH' for the partition key in DynamoDB. 'SORT' is used for sort keys, but here we define the partition key.

4fill in blank

Fill both blanks to define the attribute type and key type correctly in the table creation.

DynamoDB

"AttributeType": "[1]", "KeyType": "[2]"

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

💡 Hint

Common Mistakes

Mixing attribute types and key types.

Using 'N' when the key is a string.

The attribute type 'S' means string, which is common for keys like 'UserId'. The key type 'HASH' defines it as the partition key.

5fill in blank

hard

Fill all three blanks to complete the provisioned throughput settings for the DynamoDB table.

DynamoDB

"ProvisionedThroughput": {"ReadCapacityUnits": [1], "WriteCapacityUnits": [2], "SomeOtherSetting": [3]

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

B10

C0

D15

💡 Hint

Common Mistakes

Setting write capacity higher than read capacity without reason.

Using zero for capacity units which disables throughput.

ReadCapacityUnits is set to 15, WriteCapacityUnits to 10, and 'SomeOtherSetting' is 0 as a placeholder (not a real setting, but for exercise).
