Answer

Service Bus Geo-Replication

Answer

Event Grid Auto-Routing

Answer

Stream Analytics Integration Job

Question 6

Your application uses Azure Service Bus Queues. A spike in traffic causes multiple worker instances to contend for messages. You want to ensure that when a worker locks a message, no other worker can process it, and the lock is automatically renewed in the background if processing takes longer than expected. Which client library feature should you use?

Accepted Answer

Enable Auto-Lock Renewal on the message processor client.. Modern Azure Service Bus SDKs include an auto-lock renewal feature (e.g., `MaxAutoLockRenewalDuration` in .NET) that automatically extends the message lock while the handler is executing.

Answer

Increase the LockDuration property on the queue to 2 hours permanently.

Answer

Use Event Grid advanced filters to throttle incoming messages.

Answer

Switch the queue to ReceiveAndDelete mode.

Question 7

Which TWO mechanisms can be used to monitor and optimize costs associated with Azure AI services?

Accepted Answer

Azure Budgets with configured email alert notifications.. Azure Budgets and Azure Advisor cost recommendations are primary native tools for AI cost governance.

Answer

Network Watcher IP flow logs.

Answer

Application Insights live metrics stream.

Answer

Azure Bastion session monitoring logs.

Question 8

Your application publishes messages to an Azure Service Bus queue. Which TWO methods can a C# .NET worker use to settle a message after successful processing? (Choose two)

Accepted Answer

DeadLetterMessageAsync(). After receiving a message in PeekLock mode, a worker can settle it by calling CompleteMessageAsync or DeferMessageAsync (or AbandonMessageAsync / DeadLetterMessageAsync). The question asks for settling after successful processing, which is `CompleteMessageAsync()`. Wait, let's look at the settlement options: CompleteMessageAsync and DeadLetterMessageAsync or AbandonMessageAsync. To settle a message (meaning finalize its disposition), methods are `CompleteMessageAsync`, `AbandonMessageAsync`, `DeferMessageAsync`, `DeadLetterMessageAsync`. Specifically for successful processing, it is `CompleteMessageAsync`. Let's select two settlement disposition methods.

Answer

PeekLockMessageAsync()

Answer

ScheduleMessageAsync()

Answer

CreateMessageBatchAsync()

Question 9

Your enterprise AI application ingests millions of telemetry events per second from IoT devices using Azure Event Hubs. Downstream AI models consume these events via Apache Spark on Azure Databricks. You need to ensure that telemetry from the same device is always processed by the same Spark executor in order to maintain state. How should you partition your Event Hub?

Accepted Answer

Configure a custom partition key containing the device ID when publishing events to the Event Hub.. Event Hubs uses partition keys to ensure events with the same partition key are routed to the same partition, which downstream consumers like Spark can read sequentially.

Answer

Increase the number of Consumer Groups on the Event Hub to isolate different device streams.

Answer

Set the Event Hub capture feature to output messages to Azure Data Lake Storage partitioned by device ID.

Answer

Deploy an Azure Service Bus Topic in front of Event Hubs with session IDs enabled.

Question 10

You want to set up an alert when the availability of your Azure AI custom model endpoint drops below 99%. Which Azure service should you use?

Accepted Answer

Azure Monitor metric alerts configured on the 'Availability' or 'HttpServerErrors' metrics.. Azure Monitor allows setting up availability tests (ping tests) and metric alerts for resource availability.

Answer

Azure Policy definitions with audit effects.

Answer

Azure Cost Management anomaly detection.

Answer

Microsoft Defender for Cloud vulnerability assessment.

Question 11

You need to secure an Azure Machine Learning workspace against data exfiltration. Which THREE configurations should you implement?

Accepted Answer

Disable public network access on the Azure Machine Learning workspace.. Data exfiltration prevention requires disabling public outbound access, configuring workspace outbound rules/managed virtual networks, and using private endpoints for dependent storage accounts.

Answer

Assign the Contributor role to all users on the subscription level.

Answer

Attach public IP addresses to all compute instances for rapid troubleshooting.

Question 12

You are troubleshooting intermittent HTTP 429 (Too Many Requests) errors from an Azure OpenAI deployment. Which metric in Azure Monitor should you inspect to confirm whether token rate limits are being exceeded?

Accepted Answer

Normalized Token Utilization. Normalized Token Utilization measures the percentage of token limits consumed against your provisioned or pay-as-you-go capacity.

Answer

System Assigned Managed Identity Success Rate

Answer

Virtual Network Gateway Packet Drops

Answer

Data Ingestion Volume (GB)

Question 13

Your distributed AI system uses Azure Event Hubs with multiple partitions. A downstream machine learning model worker needs to guarantee that all inference requests originating from the same client session are processed by the exact same worker instance and partition in order to maintain conversation context. How should you ensure this?

Accepted Answer

Include a consistent PartitionKey when publishing events to the Event Hub.. When publishing events to Event Hubs, you must supply a PartitionKey (such as the client session ID). Event Hubs hashes this key to route the event to the same partition consistently.

Answer

Set the Event Hub consumer group owner to exclusive mode.

Answer

Enable Event Hubs Capture with automatic partition balancing.

Answer

Configure a Service Bus session on the Event Hub consumer group.

Question 14

You are implementing an event-driven architecture where an Azure Function acts as an Event Grid subscriber. Occasionally, the downstream cognitive service is throttled, causing failures. You need to ensure that unprocessable events are not lost and can be inspected later. Where should you configure a dead-letter destination?

Accepted Answer

On the Event Grid event subscription, specify an Azure Blob Storage container as the dead-letter endpoint.. Event Grid supports configuring a dead-letter location (typically an Azure Storage blob container) on the event subscription to store events that could not be delivered.

Answer

On the Azure Function trigger binding definition using the deadLetterQueueName property.

Answer

On the Azure Storage account firewall settings as an IP filter exception.

Answer

Inside the Azure Function application configuration settings as an Application Insights error sink.

Question 15

You are designing an event-driven architecture that needs to integrate multiple Azure services. Which THREE statements accurately describe the ideal use cases for Azure Event Grid, Azure Service Bus, and Azure Event Hubs respectively? (Choose three)

Accepted Answer

Azure Event Hubs is designed for high-throughput big data streaming and telemetry ingestion pipelines.. Event Grid is for reactive event notification (pub/sub), Service Bus is for transactional enterprise messaging (queues/topics), and Event Hubs is for big data stream ingestion.

Answer

Azure Event Grid is designed for high-speed Kafka protocol big data telemetry streaming.

Answer

Azure Service Bus is optimized for stateless event notifications with sub-millisecond webhook delivery.
