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?

1. A. Enable compaction on the topic to drop older messages, which will drop older messages with the same key.
2. B. Upgrade to a larger Apache Kafka for Heroku plan, which has greater data capacity.
3. C. Use Heroku Redis to store message receipt information to account for "at-least" once delivery, which will guarantee that messagesare never processed more than onc
4. D. Scale up the consumer dynos to match the number of partitions so that there is one process for each partition.

Universal Containers (UC) has an app that allows a costumer to schedule a compute-intensive job. It allows the costumer to schedule the job on an ad-hoc basis. UC has decided to break up the app into the following services: - Website: an Interface for their costumers; -Billing: generates monthly invoices based on usage metrics; - Traffic Cop: manages the job queue, job definitions and job schedule; - Job Runner; runs jobs that Traffic Cop queues up. It Is responsible for self-introspection and self-scaling. UC also wants to createa data lake for analytics. What foundational technology and design should an Architect use to manage communication between these services?

1. A. Apache Kafka on Heroku as a bus between all services Create topics for billing, jobs, and website clicks Create an additional service, which will subscribe for all topics, and dump every message into a data lake
2. B. Heroku Redis, create a large Redis stor
3. C. Allow each service to place messages with an agreed-upon format into a single queue, backed by the Redis storeServices listen for messages addressed to them and take action on the
4. D. Redis will serve as the data lake.
5. E. Heroku Connect and Salesforce Sync all relevant data into Salesforce and allow it to flow into each service Create custom objects for each serviceand alow them to post to each others' objects as neede
6. F. Push data from Salesforce into Heroku Postgres for a data lake.
7. G. Apache Kafka on Heroku Create a Kafka queue for each servic
8. H. Create a central routing service that connects to all of the Kafka queues and routes dat
9. I. The central router is attached to a data lake, and pushes every message into It.
