A client has data in a Heroku Postgres table. They want to generate analytics based on the table and make the results available in their Salesforce org. Their Salesforce administratorwants to minimize the amount of data that is written to Salesforce to accomplish this.
Which strategy should an Architect recommend on this scenario?
A. Use Heroku Connect to sync the Heroku Postgres table to the Salesforce org, and generate analytics fromthe Salesforce org.
B. Use the Heroku application to generate analytics, and write the results to a separate Heroku Postgres table-Expose that table to the Salesforce org with Heroku External Objects.
C. Use the Heroku application to generate analytics, and write the results to the Salesforce org with the Salesforce Bulk API.
D. Use the Heroku application to generate analytics and write them to a separate Heroku Postgres table. Sync that table to the Salesforce org with Heroku Connect.
A client has a Heroku app that uses Apache Kafka on Heroku. They want to refactor the app into 2 distinct apps that will both continue to use Kafka (because they probably don't have so much to do in their life). Based on this refactoring, what should an Architect recommend?
A. Ensure that the apps consume mutually excliusive sets of Kafka topics
B. Attach the existing Kafka add-on to both apps
C. Designate one app as a producer and the other as a consumer
D. Attach the existing Kafka add-on to one app and attach a new Kafka add-on to the other app

A client is writing a Heroku application that requirescompliance with PCI DSS Level 1. To accomplish this, they deploy an application to the Shield Private Space. Which statement is true about the application?
A. The application might still violate PCI DSS Level 1 even though it is deployed to a Shield Private Space
B. The Shield Private Space guarantees that the application is compliant with PCI DSS Level 1, assuming the application uses only Shield Postgres databases
C. The application is definitely not compliant with PCI DSS Level 1. because Shield PrivateSpaces do not provide compliance with it.
D. The Shield Private Space guarantees that the application is compliant with PCI DSS Level 1
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?
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
B. Heroku Redis, create a large Redis store. 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 them. Redis will serve as the data lake.
C. 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 needed. Push data from Salesforce into Heroku Postgres for a data lake.
D. Apache Kafka on Heroku Create a Kafka queue for each service. Create a central routing service that connects to all of the Kafka queues and routes data. The central router is attached to a data lake, and pushes every message into It.
A client is building a system that will sync data from multiple Salesforce orgs to a singleHeroku Postgres database. This system also needs to push the synced data to an external data warehouse for analytics processing. Which solution meets all of the requirements in this scenario?
A. Use Heroku Connect to synchronize data between the Salesforceorgs, the Heroku Postgres database and the external data warehouse
B. Use Salesforce Connect to synchronize data between the Salesforce orgs and the Heroku Postgres database Use Heroku Connect to sync data between the Heroku Postgres database and the external data warehouse.
C. Use Heroku External Objects to synchronize data between the Salesforce orgs and the Heroku Postgres database Use an ETL tool to push data from the Salesforce orgs to the external data warehouse.
D. Use Heroku Connect to synchronizedata between the Salesforce orgs and the Heroku Postgres database Use an ETL tool to push data from the Salesforce orgs to the external data warehouse.
