A client wants to use Heroku Connect to sync data from a Heroku Postgres table to a Salesforce org. The client only needs to sync a specific subset of the rows in the table.
How should this be performed?

A healthcare client is creating a web portal for their customers on Heroku, which is sourced from a Salesforce instance. Some of the Salesforce data they wish to display falls under HIPAA compliance, and their auditors have determined this data must be stored encrypted-at-rest. To satisfy this requirement, they have enabled Platform Encryption on Salesforce.
They are investigating Heroku Shield Private Spaces, Shield Dynos, Shield Postgres, and Shield Heroku Connect.
How will Shield Heroku Connect interact with the encrypted fields in Salesforce?

Universal Containers would like to engage contractors and customers directly in their Field Service solution.
Which three options will provide read, write, and edit access to Work Order objects? (Choose three.)

A client wants to add CPU-intensive video processing functionality to their Heroku web application.

Universal Containers (UC) uses Apache Kafka on Heroku to stream shipment inventory data in real time throughout the world. A Kafka topic is used to send messages with updates on the shipping container GPS coordinates as they are in transit. UC is using a Heroku Kafka basic-0 plan. The topic was provisioned with 8 partitions, 1 week of retention, and no compaction. The keys for the events are being assigned by Heroku Kafka, which means that they will be randomly distributed between the partitions.
UC has a single-dyno consumer application that persists the data to their Enterprise Data Warehouse (EDW). Recently, they've been noticing data loss in the EDW.
What should an Architect with Kafka experience recommend?
