Amazon Exam DVA-C02 Topic 7 Question 42 Discussion

Actual exam question for Amazon's DVA-C02 exam
Question #: 42
Topic #: 7
[All DVA-C02 Questions]

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?

I'm not sure, but I think option B could also work well by using ElastiCache to update the cache in Payments.
