A customer would like to analyze data stored in a single, large, high-traffic Heroku Postgres database using a reporting tool that runslong-running, expensive read queries. What reporting architecture should be recommended?
A client wants to create a Heroku web application that needs to provide a low-latency experience for its users, who are based primarily in Japan. Many common user actions will result in synchronous writes to the application's Heroku
Postgres database. The application does not have advanced compliance requirements.
Which should an Architect recommend?
A. Deploy the application to a Shield Private Space In the Tokyo region
B. Deploy the application to the Common Runtime in the Tokyo region
C. Deploy the application to a Private Space in the Tokyo region
D. Deploy the application to the Common Runtime in the U.S region and use a CDN to accelerate content delivery
Universal Containers has a Heroku Private Space with a VPN connection to their on- premise network. They want their remote employees to be able to access their Heroku applications using a VPN connection only. Which solution should an Architect recommend?
A. Clone the Heroku applications to a second Private Space, and configure its VPN for remote employees.
B. Enable remote employees to VPN into the company's on-premise network.
C. Configure a second VPN connection for the Private Space that remote employees can use.
D. Add all remote employees to an Enterprise Team, and configure it to connect to the Private Space via SSO.
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.
For which two use cases should an Architect recommend using Heroku Redis? (Choose two.)
A. Providing long-term data warehousing
B. Adding jobs to a queue
C. Providing a data cache layer
D. Querying relational data
A client runs an application on a background worker dyno. The application allows its users to request personalized information as a PDF. At peak usage, the app processes millions of requests at once.The resulting number of requests has caused a bottleneck that is impacting its performance.
Which two solutions can an Architect recommend to resolve the bottleneck and improve performance? (Choose two.)
A. Increase the number of workers to consume thejob faster.
B. Move the application to a Private Space.
C. Add Heroku Redis as a job queue.
D. Add a CDN add-on from the Elements marketplace.
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 messagesare never processed more than once.
D. Scale up the consumer dynos to match the number of partitions so that there is one process for each partition.
Part of a client's design is the ability to easily share between two applications running on Heroku.
What should an Architect recommend?
A. Attach a single storage add-on, such as Heroku Postgres, to both applications.
B. Create Foreign Data Wrappers to expose the tables from one database to another.
C. Provision Heroku Connect to sync the data into a custom object in Salesforce.
D. Provision Apache Kafka on Heroku to easily stream the data between the two apps.
A client wants to use Heroku Connect to sync data from a Heroku Postgres table toa Salesforce org. The client only needs to sync a specific subset of the rows in the table.
How should this be performed?
A. Add a mapping filter to the table when setting up the sync, and select appropriate criteria from the list.
B. Filter the data inthe database, and provide an alternative table or view for use in the sync.
C. Use the Heroku Connect Mapping Query Editor, and add filters to the query.
D. Place Sharing Rules on the records, and restrict visibility to only those rows that are needed.
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 inthis scenario, should an Architect recommend?
A. Custom Apex callouts
B. Heroku Connect
C. Salesforce SOAP API
D. Salesforce Connect
Universal Containers is preparing to deploy a high-volume production web application to the Heroku Common Runtime. Which two best practices should an Architectrecommend for large-scale load testing of the application? Choose 2 answers.
A. Open a ticket with Heroku support for approval.
B. Move the apps into a Private Space to provide an isolated test environment
C. Disable autoscaling to prevent applicationstartup overhead from skewing results
D. Ensure that the application runs on Performance-tier dynos
