Question 3

(Select 2)

You are developing a solution that will use Azure messaging services. You need to ensure that the solution uses a publish-subscribe model and eliminates the need for constant polling. What are two possible ways to achieve the goal? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

Question Analysis

Core Concept: This question tests Azure messaging patterns—specifically the publish-subscribe (pub-sub) model and event-driven delivery that avoids constant polling. In Azure, pub-sub means publishers send messages/events to a broker, and multiple independent subscribers receive them via subscriptions/handlers. Why the Answer is Correct: Azure Service Bus (A) supports pub-sub through Topics and Subscriptions. A publisher sends a message to a Topic, and each Subscription receives its own copy, enabling fan-out to multiple consumers. Consumers can receive messages using push-like mechanisms (e.g., Service Bus-triggered Azure Functions) rather than polling in application code. Azure Event Grid (C) is a native event routing service built for reactive architectures. It delivers events to subscribers (webhooks, Azure Functions, Logic Apps, Service Bus, etc.) with push delivery and retry, which eliminates the need for consumers to poll for changes. Key Features / Best Practices: - Service Bus Topics/Subscriptions: durable messaging, at-least-once delivery, dead-lettering, sessions (ordering), duplicate detection, filters/actions on subscriptions, and transactions. Use when you need enterprise messaging guarantees and decoupling between services. - Event Grid: push-based event distribution, built-in integration with many Azure sources (Storage, Resource Groups, etc.), filtering, advanced routing, and managed retries with dead-lettering to Storage. Use for event notification and reactive workflows. From an Azure Well-Architected Framework perspective, both improve Reliability and Performance Efficiency by decoupling producers/consumers and avoiding wasteful polling. Common Misconceptions: - Event Hubs (B) is often mistaken for pub-sub. It is primarily for high-throughput telemetry/stream ingestion with partitioned consumer groups; it’s more “streaming” than classic pub-sub messaging and typically requires consumers to read from partitions (often perceived as polling/reading) rather than push delivery. - Queue (D) (e.g., Storage Queue) is point-to-point (competing consumers) rather than pub-sub; one message is processed by one consumer, not fanned out to multiple subscribers. Exam Tips: - If the question says “publish-subscribe” and “multiple subscribers,” think Service Bus Topics or Event Grid. - If it emphasizes “event notifications” and “push to handlers,” Event Grid is the best fit. - If it emphasizes “enterprise messaging, workflows, ordering, dead-lettering, transactions,” Service Bus is the best fit. - If it emphasizes “telemetry, logs, millions of events/sec, streaming analytics,” think Event Hubs.

Question 4

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You are developing an Azure solution to collect point-of-sale (POS) device data from 2,000 stores located throughout the world. A single device can produce 2 megabytes (MB) of data every 24 hours. Each store location has one to five devices that send data. You must store the device data in Azure Blob storage. Device data must be correlated based on a device identifier. Additional stores are expected to open in the future. You need to implement a solution to receive the device data. Solution: Provision an Azure Event Grid. Configure event filtering to evaluate the device identifier. Does the solution meet the goal?

Question Analysis

Core concept: This question tests choosing the correct Azure ingestion service for device telemetry at scale and understanding the difference between Event Grid (event notification/routing) and services designed for high-throughput device-to-cloud data ingestion (IoT Hub/Event Hubs) before persisting to Blob storage. Why the answer is correct: Event Grid is primarily an event routing service for discrete events (e.g., “blob created”, “resource changed”) and is not intended to be the primary endpoint for continuous device telemetry uploads from thousands of POS devices. While Event Grid supports filtering on event metadata, it does not provide the device connectivity, ingestion semantics, or telemetry-oriented features needed to reliably receive and buffer device data streams at scale. A more appropriate pattern is to ingest device messages via Azure IoT Hub (or Event Hubs for non-IoT scenarios), then use routing/Stream Analytics/Functions to write to Blob Storage with partitioning by device identifier. Key features / configurations: - Azure Event Grid: event notification, push delivery to handlers, filtering on event subject/type/data fields, at-least-once delivery for events. - Azure IoT Hub: per-device identity, device authentication, device-to-cloud telemetry ingestion, message routing to storage/endpoints. - Azure Event Hubs: high-throughput event ingestion, partitions/consumer groups; typically paired with processors to persist to Blob. - Correlation by device identifier: use IoT Hub device ID or message properties; write to Blob paths like /deviceId=/yyyy=/mm=/dd= for efficient organization. Common misconceptions: - Assuming Event Grid is a general-purpose ingestion endpoint for arbitrary device payloads; it is mainly for routing events emitted by Azure services or custom publishers, not for direct device telemetry at scale. - Confusing “filtering” with “correlation/storage partitioning”; filtering only decides where events go, it doesn’t inherently organize or persist data by device ID. - Overlooking device management needs (identity, authentication, throttling) that IoT Hub provides. Exam tips: - Use Event Grid for reactive workflows and notifications (resource events, blob created, etc.), not for primary telemetry ingestion. - For many devices sending data: prefer IoT Hub (device identity + telemetry) or Event Hubs (stream ingestion). - If the requirement includes “correlate by device identifier,” think message properties + downstream partitioning/routing to storage. - When the destination is Blob Storage, expect an intermediate ingestion service plus a processor (Functions/Stream Analytics) or built-in routing (IoT Hub routing).
