The Salesforce Heroku Architecture Designer exam currently appears as a retired credential on Salesforce's certification site and is no longer listed as actively scheduled for new candidates. Historical exam guides describe a 60-question, 105-minute architect-tier exam at US$400 with a 67% passing score. The blueprint covered Heroku platform architecture, dyno and runtime selection, Heroku Connect, Private Spaces and Shield, and Salesforce extension patterns. We keep this practice content live because the underlying Heroku platform knowledge - dyno sizing, Postgres operations, Heroku Connect, Private Spaces vs Shield, and observability - remains directly relevant to any architect designing Salesforce-plus-Heroku solutions today.

Sample Salesforce Heroku Architect Practice Questions

Try these sample questions to test your Salesforce Heroku Architect exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which Heroku runtime is multi-tenant, runs in shared AWS infrastructure, and is the default option for most Heroku apps?

A.Private Space

B.Shield Private Space

C.Common Runtime

D.Heroku Enterprise Trust

Explanation: The Common Runtime is Heroku's default multi-tenant runtime where dynos from many customers share the same underlying infrastructure. Apps in the Common Runtime are publicly addressable and have outbound traffic that originates from a shared range of IPs.

2Which dyno process type receives HTTP traffic routed through the Heroku router?

A.worker

B.web

C.release

D.one-off

Explanation: Only processes named 'web' in the Procfile receive HTTP requests through the Heroku router. The web process must bind to the port defined in the PORT environment variable.

3What is a slug in Heroku terminology?

A.A persistent disk attached to each dyno

B.A compressed, pre-packaged copy of an application ready for execution on a dyno

C.A shared in-memory cache across all dynos

D.The metadata describing add-on attachments

Explanation: A slug is the compiled, compressed bundle of an application produced by buildpacks. When a dyno starts, the slug is copied onto the dyno and the configured process command is executed.

4Which file at the root of a Heroku application defines the process types and the commands that start them?

A.app.json

B.Procfile

C.manifest.yml

D.heroku.yml

Explanation: Procfile is the text file at the application root that declares process types such as web, worker, and release along with the command used to start each one.

5Which Heroku dyno tier is the smallest dyno explicitly designed for production workloads with no automatic sleep behavior?

A.Eco

B.Basic

C.Standard-1X

D.Performance-M

Explanation: Standard-1X is the entry-level production dyno: it does not sleep, supports horizontal scaling, and is suitable for production web and worker workloads. Eco and Basic are intended for hobby and low-traffic use.

6Which Heroku feature allows you to set runtime configuration values such as DATABASE_URL and API keys without changing source code?

A.Buildpacks

B.Config vars

C.Procfile entries

D.Pipeline environments

Explanation: Config vars are key-value pairs that Heroku exposes as environment variables to running dynos. They let you change configuration without redeploying the slug, and add-ons typically inject their connection strings as config vars.

7Which command-line tool is the primary interface for managing Heroku apps from a developer workstation?

A.heroku CLI

B.sf CLI

C.git push only

D.kubectl

Explanation: The Heroku CLI is the official command-line tool for creating apps, managing add-ons, scaling dynos, viewing logs, running one-off commands, and configuring most other platform features.

8Which deployment mechanism triggers a Heroku build by simply running 'git push heroku main'?

A.GitHub integration with auto-deploy

B.Heroku Git deployment

C.Container Registry push

D.Heroku Button

Explanation: Heroku Git deployment uses a Git remote called heroku that, when pushed to, triggers buildpack detection, slug compilation, and a release. It is the original Heroku deployment workflow.

9Which Heroku Pipeline stage is typically connected to GitHub auto-deploy from feature branches and is replaced by an isolated app per pull request?

A.Production

B.Staging

C.Review Apps

D.Development

Explanation: Review Apps spin up an isolated, ephemeral Heroku app for each open pull request, letting reviewers test changes in a real running environment before merge. They are wired up via GitHub integration.

10What does promoting an app in a Heroku Pipeline do?

A.Rebuilds the slug from source for the downstream environment

B.Copies the existing slug from the upstream app to the downstream app and creates a new release

C.Restarts dynos in the downstream app without changing code

D.Forks the upstream Heroku Postgres database to the downstream app

Explanation: Promotion ships the exact same compiled slug from the upstream app (e.g., staging) to the downstream app (e.g., production), guaranteeing the artifact tested upstream is identical to what runs downstream.

About the Salesforce Heroku Architect Exam

The Salesforce Certified Heroku Architecture Designer exam validates an architect's ability to design, deploy, and operate scalable, secure applications on the Heroku platform and to extend Salesforce with Heroku-hosted services.

Salesforce Heroku Architect Study Tips from Top Performers

1Master the runtime decision: Common Runtime is fast and cheap but multi-tenant; Private Spaces give a dedicated VPC for compliance and trusted-IP integration; Shield Private Spaces add HIPAA and PCI controls plus audit logging.

2Memorize dyno tiers and what each one supports: Eco/Basic for hobby workloads, Standard-1X/2X for production web and worker dynos, Performance-M/L for autoscaling and dedicated single-tenant CPU, Private-S/M/L for Private Spaces.

3Practice Heroku Connect decisions: read-only vs read-write vs write-only mapping direction, accelerated bulk sync, OAuth to Salesforce, and how to avoid hitting Salesforce API limits with high-volume writes.

4Drill Heroku Postgres operations: forks for safe schema changes, followers for read scaling and disaster recovery, Dataclips for shareable read-only queries, and which plan tiers support encryption and HA.

5Know the difference between preboot, restart, and release: preboot keeps old dynos running while new ones warm up to avoid request queue time during deploys.

6Understand Pipelines: development to staging to production, promotion ships the existing slug rather than rebuilding, and Review Apps spin up an isolated app per pull request.

7Practice observability: Logplex aggregates logs, log drains forward to Splunk or Sumo Logic or Papertrail, and request queue time plus autoscaling on Performance dynos drive scaling decisions.

8Understand Salesforce extension patterns: Heroku as a compute extension for heavy work, Heroku as an event handler for Platform Events or Change Data Capture, and Heroku Connect for bidirectional data sync.

Frequently Asked Questions

Is the Salesforce Heroku Architecture Designer exam still active?

The credential currently appears as retired on Salesforce's certification site and is not listed for new exam scheduling. Salesforce historically delivered it as a 60-question, 105-minute architect-tier exam at US$400 with a 67% passing score. Even though the exam is retired, the underlying Heroku platform knowledge remains relevant for any architect extending Salesforce with Heroku.

How many questions did the Heroku Architecture Designer exam have?

The published exam guide listed 60 scored multiple-choice and multiple-select questions plus up to 5 unscored items on some deliveries, with a 105-minute time limit and a 67% passing score.

What did the exam cost?

The registration fee was US$400 because this was an architect-tier Salesforce exam. The retake fee was US$200, with a 24-hour minimum wait between attempts when the exam was active.

What were the prerequisites?

There was no formal prerequisite credential. Salesforce recommended hands-on Heroku experience plus a working knowledge of Salesforce platform integration. Candidates often held Platform Developer I or Integration Architect first.

Which Heroku topics matter most for the exam?

Heroku Connect, Private Spaces vs Shield Private Spaces, dyno types and sizing, Heroku Postgres operations including followers and forks, Heroku Pipelines, and Salesforce extension patterns are the highest-value topics. Security, compliance, networking, and observability questions appear throughout.

Why are you keeping practice content for a retired exam?

Heroku itself is still a production platform that powers many Salesforce extension architectures. Architects designing Salesforce-plus-Heroku solutions still need to make the same decisions the exam tested - runtime selection, dyno sizing, Heroku Connect direction, Shield for regulated data, observability, and integration patterns.

Where can I read the historical exam guide?

The Salesforce help article 'Salesforce-Certified-Heroku-Architecture-Designer-Exam-Guide' historically hosted the official guide. Heroku Dev Center remains the authoritative source for platform behavior - dyno types, Private Spaces, Heroku Connect, Postgres, and Shield are all documented there.
