A client currently runs a Ruby script in a one-off dyno each time they deploy their Go application to Heroku. The development team wants the script to be executed before the application is deployed because it performs necessary database migrations. Which approach should an Architect recommend?

• A.Modify the Go buildpacK to install Ruby, and run the script from the _profile
• B.Convert the Ruby release script to Go and execute it on application startup
• C.Use both Go and Ruby language buildpacks, and run the Ruby script with release phase
• D.Define different process types for the Ruby script and the Go application in the app's Profile.

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 create a 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 store Services 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 service and 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 collection of Heroku applications that will be audited regularly. To comply with the audit, it must be guaranteed that the applications all forward thei logs to the same, single destination. Which solution meets this requirements?

• A.Deploy all of the applications to the Common Runtime, and attach the same ininstance of a logging add-on to all of them.
• B.Deploy all the applications to the same Shiekld Private Space with Private Space Logging enabled
• C.Deploy all the applications to the Common runtime, and add the same log drain URL to all of them.
• D.Deploy all the applications to the same Private Space with Logplrx disabled.

Universal Containers has a Heroku app that uses Heroku Connect to sync data with their Salesforce org. The app makes frequemt updates to the same records over short period of time, and sync speeds have begun to worsen. An Architect recommends using Heroku Connect's Merged Writes algorithm to improve sync speeds. What are 2 implications of using the Merged Writes algorithm in this scenario?

• A.Relationships such as circular dependencies are known to cause issues.
• B.The Merged Writes algorithm does not support using Salesforce SOAP API
• C.The Merged Writes algorithm is more likely to approach Salesforce API rate limits.
• D.The Merged Writes algorithm does not support using the Salesforce Bulk API.
