Salesforce HEROKU-ARCHITECTURE-DESIGNER Online Practice Questions and Exam Preparation

Salesforce HEROKU-ARCHITECTURE-DESIGNER Online Questions & Answers

• Question 1:

  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?

  A. Configure each microservices to directly fetch the sensor metrics that are relevant to it.
  B. Use Private Space DNS Service Discovery to reduce the amountof time required for the Metrics Microservice to obtain each other microservice's IP address
  C. Configure the other microservices to pull the Metrics Microservice for updates every five seconds
  D. Use Apache Kafka on Heroku to publish metrics to a topic that the other microservices can consume.
  D. Use Apache Kafka on Heroku to publish metrics to a topic that the other microservices can consume.

• Question 2:

  Universal Containers collects sensor data from millions of sensors that are located around the World. Now. they want to process this data on Heroku. What are three advantages of using a microservices architecture with Apache Kafka on Heroku in this scenario? Choose 3 answers.

  A. Kafka is highly available and fault-tolerant
  B. Individual services can be scaled easily for high-volume event processing
  C. Consumers and producers can be scaled independently.
  D. Individual services can efficiently communicate with each other using REST APIs.

When an invoice is ready, the Heroku app sends a POST request to the Salesforce REST API. Which two options should an Architect recommend to ensure that neither the Salesforce nor the Heroku app is accessible from the public internet? Choose 2 answers.

  A. Restrict the Private Space's trusted IP range to Salesforce IP addresses
  B. Restrict the Private Space's trusted IP range to Universal Containers' VPN
  C. Restrict the Salesforce connected app's login IP ranges to Universal Containers' VPN
  D. Restrict the Salesforce connected app's login IP ranges to the stable outbound IP addresses of the Private Space
  A. Restrict the Private Space's trusted IP range to Salesforce IP addresses
  D. Restrict the Salesforce connected app's login IP ranges to the stable outbound IP addresses of the Private Space

• Question 6:

  Which Heroku features should an Architect recommend to create a secure connection between Heroku and Microsoft Azure?

  B. Heroku Private Spaces and Private Space VPN Connections, using a compatible VPN endpoint on Azure
  C. Heroku Shield Private Spaces and Internal Routing, using Azure's built-in VPN endpoint
