Online Access Free Heroku-Architect Practice Test

A customer needs to test a database schema migration. Which approach should an Architect recommend?

• A.Fork the production database, and run the migration and tests against the fork
• B.Place the app into maintenance mode, and then perform the tests
• C.Create a follower database, and run the migration and test against the follower database
• D.Detach the Heroku Postgres add-on. and run the migration and tests against the database.

A Heroku application uses Heroku Connect to integrate with data from a Salesforce org. Since then, several fields from the Salesforce objects that were mapped using Connect have been removed. As a result,the development team will reload the mapping using Heroku Connect.
What is an implication of reloading the mapping?

• A.The mapped tables in Heroku Postgres will be truncated as part of the reload action. The data in removed fields will be lost, and synchronization will restart normally.
• B.The mapped tables in Heroku Postgres will continue to store the previously synchronized data, but synchronization will pause until manually restarted.
• C.The mapped tables in Heroku Postgres will be truncated as part of the reload action. The data in removed fields will be lost, and synchronization will pause until manually restarted.
• D.The mapped tables in Heroku Postgres will continue to store the previously synchronized data, and synchronization will restart normally.

Which Heroku feature allows you to deploy a real app complete with code, config, andadd-ons already configured?

• A.Heroku Deployment wizard
• B.git push heroku master
• C.Heroku Getting Started guides
• D.Heroku Buttons

What are two features of a ShieldPrivate Space that has Private Space Logging enabled? Choose 2 answers.

• A.All applications in the Shield Private Space forward their logs to the same destination.
• B.Applications in the Shield Private Space forward logs to a separate, high-compliance instance of Heroku's Logplex router
• C.Logs must be forwarded to a destination either within the Shield Private Space or within a VPN that includes the Shield Private Space.
• D.Applications in the shield Private Space donot forward logs to Heroku's Logplex router.

Universal Containers has a microservices architecture on Heroku. One microservice. named the Metrics Microservice. periodically fetches metrics from a fleet of loT sensors. Then, the Metrics Microservice is required to send relevant metrics to each of the other microservices using REST. When a new microservice is added to the architecture, the Metrics Microservice must send metrics to that new microservice too. As a result, adding microservices to the architecture causes performance issues. How should an Architect recommend changing this architecture to improve its scalability?

• A.Configure the other microservices to pull the Metrics Microservice for updates every five seconds
• B.Use Private Space DNS Service Discovery to reduce the amountof time required for the Metrics Microservice to obtain each other microservice's IP address
• C.Use Apache Kafka on Heroku to publish metrics to a topic that the other microservices can consume.
• D.Configure each microservices to directly fetch the sensor metrics that are relevant to it.
