In a move toward using microservices, a company's Management team has asked all Development teams to build their services so that API requests depend only on that service's data store. One team is building a Payments service which has its own database; the service needs data that originates in the Accounts database.
Both are using Amazon DynamoDB.
What approach will result in the simplest, decoupled, and reliable method to get near-real time updates from the Accounts database?

• A.Use Amazon ElastiCache in Payments, with the cache updated by triggers in the Accounts database.
• B.Use Amazon Glue to perform frequent ETL updates from the Accounts database to the Payments database.
• C.Use Amazon Kinesis Data Firehouse to deliver all changes from the Accounts database to the Payments database.
• D.Use Amazon DynamoDB Streams to deliver all changes from the Accounts database to the Payments database.

A company has an online order website that uses Amazon DynamoDB to store item inventory. A sample of the inventory object is as follows:

A developer needs to reduce all inventory prices by 100 as long as the resulting price would not be less than 500. What should the developer do to make this change with the LEAST number of calls to DynamoDB?

• A.Perform a DynamoDB Query operation with the Id. If the price is >= 600, perform an Updateltem operation to update the price.
• B.Perform a DynamoDB Updateltem operation with a condition expression of "ProductCategory IN <{"S": "Sporting Goods"}) and Price = 600".
• C.Perform a DynamoDB Updateltem operation with a condition expression of "Price >= 600".

A Developer wants to debug an application by searching and filtering log data. The application logs are stored in Amazon CloudWatch Logs. The Developer creates a new metric filter to count exceptions in the application logs. However, no results are returned from the logs.
What is the reason that no filtered results are being returned?

• A.A setup of the Amazon CloudWatch interface VPC endpoint is required for filtering the CloudWatch Logs in the VPC
• B.CloudWatch Logs only publishes metric data for events that happen after the filter is created
• C.The log group for CloudWatch Logs should be first streamed to Amazon Elasticsearch Service before metric filtering returns the results
• D.Metric data points for logs groups can be filtered only after they are exported to an Amazon S3 bucket
