Salesforce Certified Heroku Architecture Designer Exam Questions

Question 6 of 60

Universal Containers intends to build an app which will accept card payments. The app also needs to store, process, and transmit cardholder data.
Which Heroku architecture should an Architect recommend?

Common Runtime with secure, isolated containers for running the app's code.

A Private Space restricted to a set of trusted IP ranges.

A Shield Private Space with a Shield Postgres add-on.

A Private Space with Internal Routing enabled on the app.

Correct Answer: C

Question 7 of 60

A client wants to create a secure network connection between Heroku applications running in a Private Space and an AWS VPC.
Which Heroku feature should an Architect recommend to create the connection?

Internal Routing

Private Space Peering

Private Space VPN connections

Heroku Connect

Correct Answer: B

To create a secure network connection between Heroku applications running in a Private Space and an AWS VPC, the appropriate feature to use is Private Space Peering. This feature allows for the connection of a Heroku Private Space directly to an AWS VPC, providing a secure and efficient way to link the two environments.

Question 8 of 60

A client wants to add CPU-intensive video processing functionality to their Heroku web application.
Which two strategies should an Architect recommend for implementing this functionality? (Choose two.)

Add a new process type for worker dynos that pull video processing jobs from a queue.

Attach a video processing add-on from the Heroku Elements Marketplace to the application.

Delegate video processing tasks to the app's staging version to remove load from the production app.

Divide each video processing task across multiple web dynos to mitigate added CPU load.

Correct Answer: A, B

Question 9 of 60

Universal Containers has a Heroku app that uses several third-party add-ons. They now need to enforce data privacy and be compliant with General Data
Protection Regulation (GDPR).
What should an Architect advise UC regarding data residency in this scenario?

Heroku does not control where add-on providers store data.

Heroku support can configure add-ons for specific data residency needs.

Heroku guarantees the physical location of its control surface APIs.

Data residency for add-ons is covered under Salesforce's GDPR compliance.

Correct Answer: A

Heroku does not control where add-on providers store data. This is because Heroku operates in various regions but does not manage the physical storage of data for third-party add-ons. Since these add-ons are managed by external providers, they have their own data residency policies and practices, which are outside the control of Heroku. Therefore, the enforcement of data privacy and GDPR compliance will heavily rely on the third-party providers' compliance measures.

Question 10 of 60

An app uses a queue of worker dynos to perform complex image processing, but the worker dynos are occasionally running out of memory when performing the processing. All of their dynos are currently standard-1x dynos.
What should an Architect recommend in this scenario?

Add additional worker dynos.

Break up the image processing across multiple dynos.

Move the app to a Private Space.

Change the type of dynos to standard-2x.

Correct Answer: D

Changing the type of dynos to standard-2x is the recommended approach. The issue at hand is that the worker dynos are running out of memory, which means they require more resources for the complex image processing tasks. Upgrading to a higher capacity dyno, such as standard-2x, provides additional memory and CPU, which should address the memory constraints without necessarily needing to refactor the application to run on multiple dynos or move to a different infrastructure.
