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.

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.

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.

Question 1 Domain 2Data:

Heroku add-ons are cool because they:

AGive you the ability to add complex functionality to your application without having to manage the underlying software or infrastructure.

BAccessorize your dynos with over-clocked CPU power and faster I/O speeds

CCan be provisioned easily from the Heroku Enterprise Flea Market system.

DCost nothing --- billing is easy because they're always provided at no additional cost with every Heroku Enterprise account.

Correct Answer: A

Question 2 Domain 1Heroku Platform:

To satisfy the requirements of an upcoming compliance audit, a client must provide a record of all interactive commands run against a production application in the last six months. Which Heroku feature should an Architect recommend to help with this use case?

AHeroku Shield keystroke logging

BDataclips

CPrivate Space Logging

DSSH tunneling using Heroku Exec

Correct Answer: A

Question 3 Domain 2Data:

Which of the following is NOT an advantage of Salesforce Connect overETL?

AThe data is always fetched on demand

BIf the origin is offline, the data is still available via Salesforce Connect.

CStandard protocols like OData can easily proxy external data into Salesforce.

DData security can be enforced using per-user or per-application authentication.

Correct Answer: B

Explanation Heroku Connect synchronizes data bidirectionally between Salesforce and Heroku Postgres. When you write to Salesforce, the sync happens near real time automatically. For writes to Heroku Postgres, the user can choose between polling at set intervals or near real time replication. This flexibility lets you balance consistency needs against system load.

Question 4 Domain 4Heroku Enterprise:

Dataclips allows a user to choose which datastore to query. Which type of datastore is supported?

AAny datastore, provided that you have the connection URL

BHeroku Postgres

CHeroku Redis

DAny datastore connected via Heroku Connect

Correct Answer: B

Question 5 Domain 2Data:

A client wants to create a scalable set of microservices that communicate with each other, where multiple microservices have a public REST API.

Which architecture strategy allows this on Heroku?

AEach microservice is a separate Heroku app. The microservices communicate byusing Apache Kafka as a message bus.

BEach microservice is a separate process type in a single Heroku app. The microservices communicate by using Redis as a message bus.

CEach microservice is a separate private space. The microservices communicate byusing DNS Service Discovery.

DEach microservice is a separate process in a single Heroku app. The microservices communicate by using shared memory.

Correct Answer: C

Question 6 Domain 1Heroku Platform:

An existing app is experiencing performance degradation because of multiple executions of multiple, expensive SQL read queries. This SQL code cannot be optimized any further and the frequency of the execution of the queries cannot be reduced. Which two options should an Architect recommend in this scenario?

AHardcode the results of the query into app logic

BAdd a read-only HerokuPostgres follower

CCreate a database caching layer

DRestart the Heroku Postgres server to reclaim cache

Correct Answer: B, C

Question 7 Domain 2Data:

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?

AConfigure each microservices to directly fetch the sensor metrics that are relevant to it.

BUse Private Space DNS Service Discovery to reduce the amountof time required for the Metrics Microservice to obtain each other microservice's IP address

CConfigure the other microservices to pull the Metrics Microservice for updates every five seconds

DUse Apache Kafka on Heroku to publish metrics to a topic that the other microservices can consume.

Correct Answer: D
