💡 Hint

Common Mistakes

Using PROVISIONED instead of PAY_PER_REQUEST

Using ON_DEMAND which is not a valid billing mode string

The correct billing mode for on-demand capacity in DynamoDB is PAY_PER_REQUEST. This mode automatically scales read and write capacity.

Common Mistakes

Using a string instead of a number

Setting capacity to zero which disables reads

ReadCapacityUnits must be a number. Setting it to 10 means the table can handle 10 strongly consistent reads per second.

Fix the error in the code to correctly specify the billing mode for provisioned capacity.

AWS

💡 Hint

Common Mistakes

Using ON_DEMAND or PAY_PER_REQUEST instead of PROVISIONED

Using an invalid string like STANDARD

The billing mode string for provisioned capacity is PROVISIONED. This tells DynamoDB you will specify capacity units manually.

Fill both blanks to define a DynamoDB table with provisioned capacity and 5 write units.

AWS

BillingMode: "[1]",
ProvisionedThroughput: {
  ReadCapacityUnits: 10,
  WriteCapacityUnits: [2]
}

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

Common Mistakes

Using PAY_PER_REQUEST with ProvisionedThroughput

Setting WriteCapacityUnits to a string

Use PROVISIONED billing mode to specify capacity units manually. WriteCapacityUnits is set to 5 as required.

Fill the two blanks to create a DynamoDB table with on-demand capacity and a table name 'Orders'.

AWS

💡 Hint

Common Mistakes

Using PROVISIONED billing mode for on-demand settings

Including ProvisionedThroughput for on-demand (causes validation error)

TableName is 'Orders'. BillingMode for on-demand is 'PAY_PER_REQUEST'. ProvisionedThroughput is not needed (and invalid) for on-demand capacity.
