Post requests to a system that is not always available and limited in its ability to process high volumes of messages.

✑ Allow peer-to-peer communication between on-premises services and cloud-based model-driven Microsoft Power Platform apps.
✑ Stream large volumes of data from the company's website to a live Power BI dashboard.
✑ Support enterprise-level integrations with Dynamics 365 that can be billed on a consumption basis.
You need to use an Azure service for the integration requirements.

Suggested Answer:
Box 1: Azure Service Bus -
Post requests to a system that is not always available and limited in its ability to process high volumes of messages.
Azure Service Bus is a fully managed enterprise message broker with message queues and publish-subscribe topics (in a namespace). Service Bus is used to decouple applications and services from each other, providing the following benefits:
Load-balancing work across competing workers
Safely routing and transferring data and control across service and application boundaries
Coordinating transactional work that requires a high-degree of reliability

Box 2: Azure Relay -
Allow peer-to-peer communication between on-premises services and cloud-based model-driven Microsoft Power Platform apps.
The Azure Relay service enables you to securely expose services that run in your corporate network to the public cloud. You can do so without opening a port on your firewall, or making intrusive changes to your corporate network infrastructure.
The relay service supports the following scenarios between on-premises services and applications running in the cloud or in another on-premises environment.
Traditional one-way, request/response, and peer-to-peer communication
Event distribution at internet-scope to enable publish/subscribe scenarios
Bi-directional and unbuffered socket communication across network boundaries

Box 3: Azure Event hub -
Stream large volumes of data from the company's website to a live Power BI dashboard.
Event Hubs is a fully managed, real-time data ingestion service that's simple, trusted, and scalable. Stream millions of events per second from any source to build dynamic data pipelines and immediately respond to business challenges.

Box 4: Azure Functions -
Support enterprise-level integrations with Dynamics 365 that can be billed on a consumption basis.
One of three Azure Functions billings option is completely serverless, with the consumption plan based on resources consumed and number of executions.
Incorrect:
Logic Apps has a pure pay-per-usage billing model. You pay for each action that gets executed. It's important to be aware that you also need to pay for polling triggers, which can be a hidden cost.

Definitely. It's how the market LogicApps, you *can* use consumption but have a standard plan for bigger scenarios. Side note: we got a Logic App integration scenario for a couple customers. If you do your sizing correctly the cost isn't an issue.

Post requests to a system that is not always available and limited in its ability to process high volumes of messages: Azure Service Bus1 provides reliable message queuing and durable publish-subscribe messaging, making it suitable for intermittent connectivity and varying loads. Allow peer-to-peer communication between on-premises services and cloud-based model-driven Microsoft Power Platform apps: Azure Relay2 enables hybrid connections without requiring changes to corporate firewall or network infrastructure. Stream large volumes of data from the company’s website to a live Power BI dashboard: Azure Event Hubs3 is designed for ingesting massive amounts of event data in real-time and streaming it into data processing tools or storage systems. Support enterprise-level integrations with Dynamics 365 that can be billed on a consumption basis: Azure Logic Apps4 provides scalable integrations across different services with pay-as-you-go pricing.

Since the question did not mention to use solution with minimal possible cost, I would go for Azure Logic Apps for #4 as it is more appropriate for an "enterprise-level integrations" secnario

I would go with logic apps for question 4. both logic apps and functions are billed by consumption basis, logic apps focus on workflow and functions on functions. Based on question, workflow seems more apriority here

Answers are correct. Azure functions use consumption model too, allow for more functionality and are in fact usually much cheaper than logic apps

I think from an enterprise perspective, logic apps are a best answer to number 4: https://learn.microsoft.com/en-us/azure/azure-functions/functions-compare-logic-apps-ms-flow-webjobs

All provided answers are correct, I think. For #4, Azure Functions "Support" enterprise-level integrations. A logic app or Power Automate Flow can call an Azure Function to perform a complex calculation/logic.
