A customer's Heroku Redis instance regularly reaches its storage limit. Besides upgrading to a bigger plan, what solution should an Architect recommend for this scenario?

• A.Create a fork of the primary Heroku Redis instance.
• B.Failover to ephemeral filesystem for the running dyno
• C.Explore a different key eviction scheme.
• D.Migrate the data to a Heroku Postgres database

At Universal Containers (UC), a developer named Yuichiro wrote a PHP application that, in production, uses a MySQL database. Yuichiro is onboarding Mary, a new UC developer, who is setting up her development environment. Yuichiro asks Mary to:
1) install the related PHP libraries manually so the application will run;
2) use MongoDB, instead of MySQL, in the development environment.
According to the Twelve-Factor methodology, which changes should an Architect recommend?

• A.Recursively determine code dependencies on application startup and maintain separate Git branches for the MongoDB- and MySQL- compatible versions of the application.
• B.Persist code dependencies in the application's production database. Use the same type of database locally to ensure that the dependencies are accessible.
• C.Explicitly declare code dependencies in the application's environment variables and use the same type of database in both development and production.
• D.Explicitly declare code dependencies in the application's source and use the same type of database in both development and production.

Universal Containers experienced an outage with their production Heroku Postgres database due to a fault with the underlying infrastructure. The database was unavailable for an hour. The database is on the Standard-0 plan.
Which two actions should an Architect recommend to mitigate such database failures and outages in the future? (Choose two.)

• A.Migrate the database to a Premium-tier plan.
• B.Create a follower database that uses the same plan as the leader.
• C.Create a fork of the database that uses the same plan as the leader.
• D.Migrate the database to a larger Standard-tier plan.

Universal Containers has 3 Heroku apps in its microservices and requires that logs for all of the apps be stored in the same location for analysis and alerting purposes. How would they achieve this?

• A.Set up a file on the filesystem and share it with all the apps
• B.Install a logging add-on for one app and attach it to the other two apps
• C.Send logs from each app to their own Heroku redis Store, and then combine all logs in a fourth master store.
• D.Set up the 3 apps as producers for Apache Kafka on Heroku and save their logs to Kafka

A hospital wants to build a mobile app that allows patients to check the status of submitted insurance claims, which the hospital stores in Salesforce Health Cloud. The app's back end will run on Heroku.
Which two measures should an Architect recommend to help ensure that the app is compliant with HIPAA?
(Choose two.)

• A.Use only Heroku Shield Postgres databases to store claim data outside of Salesforce Health Cloud.
• B.Use Heroku Shield Connect to sync claim data from Salesforce to a Heroku Postgres database.
• C.Ensure that the mobile app can only run when on the hospital's intranet, which is connected to the back end's Shield Private Space via VPN.
• D.Ensure that the back-end application's code encrypts all claim data before writing it to a Heroku Postgres database.
