B. Amazon DynamoDB global tables https://aws.amazon.com/dynamodb/global-tables/ "Amazon DynamoDB global tables is a fully managed, serverless, multi-Region, and multi-active database. Global tables provide you 99.999% availability, increased application resiliency, and improved business continuity. As global tables replicate your Amazon DynamoDB tables automatically across your choice of AWS Regions, you can achieve fast, local read and write performance."

Selected Answer: B

DynamoDB is the only database that provides truly automated fail-over (cross-region) and active-active (multi-active) access.

ChatGPT: If the restored Amazon DocumentDB cluster endpoint is not accessible, the database specialist should check the cluster's security group settings to ensure that the appropriate inbound rules are configured to allow incoming connections. Therefore, none of the options presented in the question would solve the connectivity issue. A and B refer to the cluster's parameter group, which does not affect connectivity to the cluster endpoint. Parameter groups are used to configure database engine settings.

C suggests configuring the interface VPC endpoint and associating the new Amazon DocumentDB cluster. However, this option is not relevant to the issue at hand as it relates to network connectivity within the VPC. D suggests using AWS DataSync to run the syncInstances command, which is also not relevant to this issue. DataSync is a data transfer service, and running the syncInstances command does not solve connectivity issues to an Amazon DocumentDB cluster. Therefore, the database specialist should verify the security group rules for the Amazon DocumentDB cluster to ensure that the necessary inbound rules are configured to allow incoming connections.
