What skills do I need before taking the Heroku Architect exam?

You should have hands-on experience building and deploying applications on Heroku, familiarity with databases and add-ons, and a solid understanding of Salesforce architecture. There are no formal prerequisites listed, but this is a platform architecture exam that assumes production-level Heroku knowledge.

Is the Heroku Architect exam harder than other Salesforce architect exams?

The Heroku Architect exam focuses on infrastructure, scaling, and platform-specific patterns rather than point-and-click configuration, which some candidates find more abstract. The 28% weighting on Heroku Enterprise features means you need deep knowledge of advanced deployment scenarios.

How much time should I spend preparing for the Heroku Architect certification?

Most candidates need 3 to 6 months of study combined with hands-on project work to be ready. If you already have production experience with Heroku and its ecosystem, you may need less time.

What is the Heroku Enterprise domain and why is it weighted so heavily?

Heroku Enterprise covers Private Spaces, Heroku Shield compliance features, and Enterprise Teams. It is weighted at 28% because organizations running critical production workloads rely on these features for governance, compliance, and network isolation.

What is the difference between Private Space Runtime and Common Runtime for architecture decisions?

Common Runtime is Heroku's shared infrastructure suitable for most applications, while Private Space Runtime offers isolated infrastructure, network isolation, and compliance certifications. The exam expects you to know when each is appropriate based on security and compliance needs.

What role does Apache Kafka play in Heroku architecture?

Kafka on Heroku enables asynchronous, event-driven communication between services and functions in a microservices setup. The exam covers both direct Kafka use cases and building orchestration layers around it for distributed systems.

How long is the Heroku Architect certification valid once I pass?

Salesforce has not published an expiration date for this certification on the official exam page. You should verify the current validity period on the Salesforce certification website.

What does the Heroku Platform domain cover beyond just deploying apps?

This domain covers buildpacks and slug creation to help you understand how Heroku packages your application code. It also includes architecture patterns using add-ons and marketplace components to make applications performant during traffic spikes.

Where do I take the Heroku Architect exam and what format is it?

The exam is 60 multiple-choice questions delivered in 105 minutes, but the exact delivery method and test centre information should be confirmed on the official Salesforce certification portal.

Heroku-Architect Practice Questions with Explained Answers

Q: How do I integrate Heroku apps with Salesforce Lightning Platform?

Heroku Connect is the primary integration pattern for real-time sync between Salesforce and Heroku Postgres, using External IDs for record matching. Other techniques like APIs, webhooks, and middleware patterns are also covered in the Integrations domain.

Question 2 Domain 1Heroku Platform

A client is creating a new API application. The app should only be accessible from other apps that they deploy to Heroku. Also, traffic between the other apps and the API should not transit the public internet.

Which solution should an Architect recommend to meet these requirements?

ACreate the application in a Private Space with default options.

BCreate the application in a Private Space and restrict the application's set of trusted IP ranges.

CCreate the application with Internal Routing enabled, in a Private Space.

DCreate the application in a Shield Private Space to enforce stricter requirements for TLS termination.

Correct Answer: B

Question 3 Domain 6Integrations

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?

AExplicitly declare code dependencies in the application's environment variables and use the same type of database in both development and production.

BPersist code dependencies in the application's production database. Use the same type of database locally to ensure that the dependencies are accessible.

CRecursively determine code dependencies on application startup and maintain separate Git branches for the MongoDB- and MySQL- compatible versions of the application.

DExplicitly declare code dependencies in the application's source and use the same type of database in both development and production.

Correct Answer: B

Question 4 Domain 5Architect Applications

A client's Heroku web application displaysdata that is fetched from a back-end file storage system. The client now wants this data to be viewable, but not editable, from their Salesforce org.

Which recommendation should an Architect make in this scenario?

AReplicate the files to tables in a Heroku Postgres database, and use Heroku Connect to synchronize the tables to the Salesforce org.

BStore all file URLs in a Heroku Postgres table, and use Heroku Connect to synchronize the table to the Salesforce org.

CReplicate the files to tables in aHeroku Postgres database, and use Heroku External Objects to expose the tables to the Salesforce org.

DReplicate the files to the application's local filesystem, and use worker dynos to periodically sync them to the Salesforce org.

Correct Answer: A

Explanation Work Types allow you to categorize different service types like installation, repair, and consulting. Service Report Templates then enable you to create customized reports specific to each work type. Together, these configurations let technicians generate the right report format for whatever service they just completed. Other options like field service history or scheduling rules don't provide the template customization needed for different report types.

Question 5 Domain 5Architect Applications

Which two logs and logging recommendations are prescribed by the Twelve-Factor app methodology? Choose 2 answers.

AApps should not concernthemselves with routing or storing logs

BLogs from all processes and backing services should be aggregated together.

CLogs should be written to a shared file system for scalability.

DApps should only keep a limited, rolling buffer of logs available

Correct Answer: A, B
