Suggested answer: B

Explanation:

https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.managing.elb.htmlBy default, Elastic Beanstalk creates an Application Load Balancer for your environment when you enable load balancing with the Elastic Beanstalk console or the EB CLI. It configures the load balance rto listen for HTTP traffic on port 80 and forward this traffic to instances on the same port. You can choose the type of load balancer that your environment uses only during environment creation.

Later, you can change settings to manage the behavior of your running environment's load balancer, but you can't change its type.

An Amazon DynamoDB table uses a Global Secondary Index (GSI) to support read queries. The primary table is write-heavy, whereas the GSI is used for read operations. Looking at Amazon CloudWatch metrics, the Developer notices that write operations to the primary table are throttled frequently under heavy write activity. However, write capacity units to the primary table are available and not fully consumed. Why is the table being throttled?

The GSI write capacity units are underprovisioned
