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 develop a software as a service (SaaS) offering to manage photographs. Users upload photos to a web service which then stores the photos in Azure Storage Blob storage. The storage account type is General-purpose V2. When photos are uploaded, they must be processed to produce and save a mobile-friendly version of the image. The process to produce a mobile-friendly version of the image must start in less than one minute. You need to design the process that starts the photo processing. Solution: Trigger the photo processing from Blob storage events. Does the solution meet the goal?

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 Service Bus. Configure a topic to receive the device data by using a correlation filter. Does the solution meet the goal?

You are developing an e-commerce solution that uses a microservice architecture. You need to design a communication backplane for communicating transactional messages between various parts of the solution. Messages must be communicated in first-in-first-out (FIFO) order. What should you use?

Análisis de la pregunta

Core concept: This question tests Azure messaging services used as a communication backplane in microservices, specifically requiring transactional messaging with first-in-first-out (FIFO) delivery. In Azure, the service designed for reliable, ordered, transactional messaging between services is Azure Service Bus (queues/topics), especially when using sessions. Why the answer is correct: Azure Service Bus supports enterprise messaging patterns needed in microservice architectures: durable message storage, competing consumers, dead-lettering, duplicate detection, scheduled delivery, and—critically for this question—FIFO ordering when you use message sessions (SessionId). With sessions enabled on a queue or subscription, Service Bus guarantees ordered processing within a session and ensures that only one consumer processes a given session at a time, preserving FIFO semantics for that message stream. Service Bus also supports transactions (send/complete/defer/dead-letter in a transaction scope), which aligns with “transactional messages” requirements. Key features and best practices: Use a Service Bus Queue for point-to-point commands or a Topic/Subscription model for pub-sub events/commands. Enable Sessions to achieve FIFO ordering (per session) and design your partitioning strategy: choose a SessionId that represents the ordering boundary (for example, OrderId or CustomerId). Configure retry policies, max delivery count, and dead-letter queues for poison messages. Consider Premium tier for predictable latency and dedicated resources; Standard supports sessions too, but Premium is often recommended for critical backplanes. This aligns with Azure Well-Architected Framework reliability principles (durable messaging, backpressure, and failure isolation). Common misconceptions: Storage Queues are simpler and cheaper, but they don’t provide strict FIFO guarantees in the way Service Bus sessions do, and they lack many enterprise messaging features (transactions across operations, topics/subscriptions, advanced dead-lettering controls). Event Hubs is for high-throughput telemetry streaming, not transactional command messaging. Event Grid is for event routing with at-least-once delivery and no FIFO guarantee. Exam tips: When you see “transactional messaging,” “FIFO,” “commands,” “microservices backplane,” or “enterprise messaging,” think Azure Service Bus. If the question mentions “telemetry/streaming,” think Event Hubs; if it mentions “react to Azure resource events,” think Event Grid; if it mentions “simple queueing with basic features,” think Storage Queues.
