Quick Answer
The answer is Azure Functions and Azure Logic Apps, as both services can implement a serverless event-driven architecture that processes messages from a queue and stores results in a database. Azure Functions provides a lightweight, code-first compute trigger that responds to events from Azure Queue Storage, executing custom logic for each message, while Azure Logic Apps offers a low-code workflow orchestrator that can poll queues, apply conditional logic, and directly write outputs to databases like Cosmos DB or SQL Server. On the Microsoft Azure Solutions Architect Expert AZ-305 exam, this question tests your ability to distinguish between serverless compute services and messaging or batch services—a common trap is confusing Azure Service Bus (a message broker) or Azure Event Grid (an event router) with queue-processing compute triggers. Remember the memory tip: “Functions and Logic Apps are the workers; Service Bus and Event Grid are the postmen.”
This AZ-305 practice question tests your understanding of design infrastructure solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO Azure services can be used to implement a serverless event-driven architecture that processes messages from a queue and stores results in a database? (Choose two.)
Azure Logic Apps
Can be triggered by queue messages and orchestrate workflows.
Azure Event Grid
Why wrong: Event Grid is for event routing, not queue processing.
Azure Service Bus
Why wrong: Service Bus is a messaging service, not a compute trigger.
Azure Functions
Can be triggered by queue messages and process them.
Azure Batch
Why wrong: Batch is for batch computing, not event-driven queue processing.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Azure Logic Apps
A and D are correct. Azure Functions can process messages from Azure Queue Storage; Azure Logic Apps can also process messages from queues and orchestrate workflows. B is wrong because Azure Event Grid is for event routing, not queue processing. C is wrong because Azure Batch is for parallel compute jobs. E is wrong because Azure Service Bus is a messaging service, not a compute trigger in serverless context.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
