Question 9

You are designing an enterprise cloud solution that integrates Azure Event Grid, Azure Service Bus, and Azure Event Hubs. You need to select the appropriate service for three specific event-driven scenarios. Which THREE pairings of Azure messaging service to scenario are correct? (Choose three)

Accepted Answer

Azure Service Bus for managing financial transactions requiring strict ordering, sessions, and dead-lettering.. Event Grid is for reactive discrete events; Event Hubs is for big data telemetry streaming; Service Bus is for enterprise transactional messaging.

Answer

Azure Event Hubs for triggering real-time serverless webhooks upon user profile updates.

Answer

Azure Event Grid for streaming continuous IoT sensor telemetry into Azure Databricks.

Question 10

You are designing a secure enterprise event-driven architecture. Events published to an Azure Event Grid Domain must be partitioned based on a tenant ID. How should publishers send events to the Event Grid Domain to ensure proper routing to domain topics?

Accepted Answer

Publish events directly to the Event Grid Domain endpoint and specify the subject or topic name within the event structure.. When publishing to an Event Grid Domain, publishers include the domain topic name in the event metadata (or path for custom schemas), which Event Grid uses to route the event to the correct topic.

Answer

Send all events to an Azure Service Bus Topic, then configure a logic app to forward them to Event Grid.

Answer

Use Azure Event Hubs capture keys to route events to tenant-specific storage containers.

Answer

Create separate Event Grid custom topics for each tenant and configure an Azure API Management gateway to multiplex the requests.

Question 11

You are integrating an external SaaS platform with your Azure AI architecture using Azure Event Grid. The external partner wants to ensure that the events they receive from your custom topic are authentic and originated from your Event Grid namespace. Which security feature should you advise the partner to verify?

Accepted Answer

Validate the event delivery request using the AEG-Signature HTTP header and webhook HMAC verification.. Event Grid delivers events with a signature in the `AEG-Signature` HTTP header, which partners can validate using the public key or HMAC validation against the webhook secret key.

Answer

Check the Azure Active Directory tenant ID in the Event Hubs connection string.

Answer

Verify the SAS token attached to the event payload body.

Answer

Inspect the Storage account access key provided in the event subject.

Question 12

Your team is building an AI document parser. When a user uploads a PDF to Azure Blob Storage, an event triggers an Azure Function. You want to view the delivery success rate and latency metrics of these events in the Azure Portal. Which Azure service dashboard provides these metrics out-of-the-box?

Accepted Answer

Answer

Azure AI Services Dashboard

Question 13

Your enterprise architecture uses Azure Service Bus Topics and Subscriptions with geo-disaster recovery paired namespaces. A disaster occurs, and you trigger a failover to the secondary region. What happens to the messages currently in the subscriptions of the primary namespace?

Accepted Answer

Messages remaining in the primary namespace are not automatically replicated to the secondary namespace; failover relies on metadata synchronization.. When performing a geo-disaster recovery failover in Azure Service Bus, metadata is synced, but uncommitted or queued messages in the primary namespace do not automatically replicate to the secondary namespace unless using active-active replication, meaning clients must be designed to handle failover state.

Answer

All queued messages are automatically migrated to the secondary region within 5 seconds.

Answer

Azure Event Grid automatically replays all lost messages from the storage capture.

Answer

The primary namespace messages are permanently deleted and cannot be recovered.

Question 14

Your team is building an AI solution that processes thousands of images uploaded to Azure Blob Storage daily. Each image upload must trigger an immediate Azure Function to invoke Azure Cognitive Services for metadata extraction. Which event-driven messaging service should you choose for this near real-time pub/sub architecture?
