D: This action is important because if the WriteThrottleEvents metric is high, it indicates that DynamoDB is throttling writes due to insufficient write capacity. By increasing the maximum WCUs, you ensure that the table can handle the increased write throughput required by the Lambda function, thus reducing delays in order processing. even though DynamoDB has auto-scaling enabled, it’s still important to monitor the WriteThrottleEvents metric. Auto-scaling adjusts capacity based on the workload, but it may not always keep up with sudden spikes in demand or be configured optimally for this specific use case. Ensuring that the maximum write capacity units (WCUs) are set appropriately can help prevent throttling during peak times.

Eventhough the statement say "The DynamoDB table has auto scaling enabled for read and write capacity." A and D still are a good answer. Option C looks at the NumberOfMessagesSent metric and suggests increasing the SQS queue visibility timeout. This action is more relevant when messages are not being processed before the visibility timeout expires, but it does not seem to be the primary issue in this scenario.
