A client's Heroku application syncs data between a Heroku Postgres database and a Salesforce org using the Salesforce Bulk API. The client has determined the application currently uses 90% of the client's daily Salesforce Bulk API limit. To overcome this issue, what feature, to replace the Bulk API implementation in this scenario, should an Architect recommend?
A. Custom Apex callouts
B. Heroku Connect
C. Salesforce SOAP API
D. Salesforce Connect
Universal Containers (UC) uses Apache Kafka on Heroku to stream shipment inventory data in real time throughout the world. A Kafka topic is used to send messages with updates on the shipping container GPS coordinates as they are in transit. UC is using a Heroku Kafka basic-0 plan. The topic was provisioned with 8 partitions, 1 week of retention, and no compaction. The keys for the events are being assigned by Heroku Kafka, which means that they will be randomly distributed between the partitions.
UC has a single-dyno consumer application that persists the data to their Enterprise Data Warehouse (EDW). Recently, they've been noticing data loss in the EDW.
What should an Architect with Kafka experience recommend?
A. Enable compaction on the topic to drop older messages, which will drop older messages with the same key.
B. Upgrade to a larger Apache Kafka for Heroku plan, which has greater data capacity.
C. Use Heroku Redis to store message receipt information to account for "at-least" once delivery, which will guarantee that messages are never processed more than once. Scale up the consumer dynos to match the number of partitions so that there is one process for each partition.
A client is running an app on 20 Standard-2x dynos. They are noticing highly variable performance when the application is experiencing a heavy load. Which two suggestions should an Architect make in this scenario? (Choose two.)
A. Configure the app to use Standard-lx dynos.
B. Configure the app to use Performance dynos.
C. Install a performance monitoring tool.
D. Add additional Standard-2x dynos.
A healthcare client is creating a web portal for their customers on Heroku, which is sourced from a Salesforce instance. Some of the Salesforce data they wish to display falls under HIPAA compliance, and their auditors have determined this
data must be stored encrypted-at-rest. To satisfy this requirement, they have enabled Platform Encryption on Salesforce.
They are investigating Heroku Shield Private Spaces, Shield Dynos, Shield Postgres, and Shield Heroku Connect.
How will Shield Heroku Connect interact with the encrypted fields in Salesforce?
A. Shield Heroku Connect will be able to access only cypher text in the fields from Salesforce. They will need to import the encryption key from Salesforce to decrypt to store in Shield Postgres.
B. Shield Heroku Connect will be able to synchronize data from fields in Salesforce without additional customization, but any writes will need to be encrypted using the Salesforce encryption key first before being written.
C. Shield Heroku Connect requires customization on the Salesforce side to decrypt the data before transmitting to Heroku.
D. Shield Heroku Connect will be able to synchronize data bidirectionally without additional customization.
A financial reporting application, hosted on an on-premise server, uses a native library (wkhtmltopdf) to convert its HTML reports into PDFs. The app is being migrated to Heroku. What option should an Architect recommend to enable the Heroku application to use wkhtmltopdf?
A. Ensure that the Heroku app fetches the wkhtmltopdf library from cloud storage on dyno restart.
B. Install the dependency using sudo apt install wkhtmltopdf from .profile in the project root.
C. Continue to host wkhtmltopdf on-premise, and build a REST API so the library can be invoked from the Heroku app.
D. Use a custom buildpack to install wkhtmltopdf using apt.
A customer wants to sync data between their Salesforce org and Heroku Postgres.
Which two limitations should an Architect remember when recommending Heroku Connect? (Choose two.)
A. Heroku Connect can only access fields and objects that its associated Salesforce integration user can access.
B. Heroku Connect does not support all Salesforce objects and fields.
C. Heroku Connect does not provide an API.
D. Heroku Connect cannot sync custom objects.
A client wants to perform complex processing on large data sets in Salesforce. The data is confidential, but it does not have advanced compliance requirements. What Heroku Enterprise features should an Architect recommend in this scenario?
A. Shield Private Spaces and Heroku External Objects
B. Private Spaces and Heroku Connect
C. Private Spaces and Heroku External Objects
D. Shield Private Spaces and Heroku Shield Connect
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 continue to store the previously synchronized data, and synchronization will restart normally.
B. 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.
C. The mapped tables in Heroku Postgres will continue to store the previously synchronized data, but synchronization will pause until manually restarted.
D. 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.
Universal Containers has recently experienced a higher volume of traffic on their mobile app hosted on Heroku. When Universal Containers was running 4 standard-2x dynos with 1 GB RAM each, they encountered multiple H12 ("request timeout") errors. The app never consumed more than 800 MB of RAM. They then switched to performance-m dynos, with 2.5 GB RAM, and set autoscaling to a maximum of 2 dynos. However, they still encountered H12 ("request timeout") errors.
What remediation should an Architect recommend to alleviate this problem?
A. Move long-running tasks to worker dynos.
B. Add a logging add-on from the Elements marketplace.
C. Upgrade to performance-L dynos with 14 GB RAM.
D. Replace autoscaling with a manual scaling option of 2.
A client wants to secure their web application using SSL/TLS. They do not have specific requirements regarding using a particular version of SSL/TLS. Which two Heroku features should an Architect recommend as options? (Choose two.)
A. Heroku Private Spaces
B. Automated Certificate Management
C. Heroku SSL
D. Heroku Shield Private Spaces
