Question 2

Your organization is building a multi-tenant AI platform. Tenants publish custom events to an Azure Event Grid topic. You need to ensure that tenant A's subscribers only receive events where the event subject starts with "tenant-a/". Which Event Grid feature should you implement on the event subscription?

Accepted Answer

Event Grid Advanced Filters with a StringBeginsWith operator on the subject property.. Event Grid subscriptions support advanced filters and subject filters (startsWith/endsWith) to selectively route events to specific endpoints.

Answer

Service Bus Topic Filters and Actions with SQL filter syntax.

Answer

Event Hubs Capture filtering rules based on partition keys.

Answer

Azure API Management policies applied to the Event Grid custom topic ingress endpoint.

Question 3

You need to check the health status of Azure AI services globally and see if any regional outages are currently impacting your deployed models. Which Azure tool should you consult?

Accepted Answer

Azure Service Health. Azure Service Health provides a personalized view of Azure service health, planned maintenance, and regional outages affecting your resources.

Answer

Azure Cost Management

Answer

Azure Policy

Answer

Azure Advisor

Question 4

Your enterprise AI system processes sensitive Personal Identifiable Information (PII). Compliance regulations require that audit logs capturing who accessed the AI endpoints must be retained immutably for 5 years without possibility of deletion. Where should you configure this immutability policy?

Accepted Answer

Azure Storage account container immutability policies with time-based retention. Azure Storage account containers can be configured with time-based retention immutability policies (WORM - Write Once, Read Many) when exporting diagnostic logs via diagnostic settings.

Answer

Azure Active Directory audit log retention configuration

Answer

Application Insights retention settings configured via the portal

Answer

Azure Key Vault soft-delete and purge protection

Question 5

You are configuring an Azure Service Bus Topic and Subscriptions for an AI text classification system. Which THREE filter types are supported on Service Bus subscriptions for routing messages? Each correct answer represents a valid filter type.

Accepted Answer

Boolean Filters (True/False filters). Azure Service Bus supports Correlation Filters, SQL Filters, and Boolean Filters (TrueFilter/FalseFilter) on subscriptions.

Answer

Regex Pattern Matching Filters

Answer

Machine Learning Inference Filters

Question 6

When designing an Azure Event Hubs streaming pipeline for AI telemetry, which THREE components or configurations are required to consume events reliably using the EventProcessorClient? Each correct answer represents a necessary element.

Accepted Answer

A Checkpoint Store (such as an Azure Blob Storage container client). Using EventProcessorClient requires an Event Hubs connection string, a consumer group, and a checkpoint store (such as Azure Blob Storage).

Answer

An active Azure Service Bus subscription connection

Answer

An Event Grid custom topic endpoint URL

Question 7

Your company policy requires all outbound traffic from an Azure Machine Learning workspace to pass through a centralized firewall. Which feature must be implemented?

Accepted Answer

Configure workspace outbound rules with fully qualified domain name (FQDN) tags and route traffic through Azure Firewall.. Workspace outbound rules combined with a user-defined route (UDR) and a firewall (such as Azure Firewall) enforce forced tunneling and network restriction.

Answer

Enable public network access with selected IP addresses set to the firewall IP.

Answer

Use Azure Bastion to inspect all outbound connections from the workspace nodes.

Answer

Deploy the workspace without virtual network isolation and rely on Network Security Groups.

Question 8

You are deploying an event-driven AI workflow using Azure Service Bus. Which TWO mechanisms help ensure message delivery reliability and prevent data loss during transient outages? Each correct answer represents a valid reliability mechanism.

Accepted Answer

Duplicate detection using a configurable time window. Service Bus provides dead-lettering for failed messages and duplicate detection to prevent redundant processing.

Answer

Event Hubs partition auto-deletion

Answer

Event Grid webhook retry push loops with infinite retention

Answer

Storage Queue client-side polling loops

Question 9

Your enterprise AI solution requires secure connectivity between Azure Event Grid and private webhook endpoints. Which THREE features support secure, private event delivery? Each correct answer represents a valid security feature.

Accepted Answer

Private Endpoints for inbound event publishing connectivity. Event Grid supports managed identities for webhooks, private endpoints for ingress, and IP firewalls.

Answer

Service Bus shared access signature (SAS) keys on event subscriptions

Answer

Anonymous public webhook access bypass headers

Question 10

Your machine learning engineering team needs to run training jobs on Azure Machine Learning compute clusters. To minimize costs during off-peak hours, you need to configure the compute cluster to automatically scale down to zero nodes when no jobs are queued, and scale up when jobs are submitted. What setting should you configure on the compute cluster?

Accepted Answer

Set the minimum number of nodes to 0 and the maximum nodes according to workload requirements. Configuring the minimum number of nodes to 0 on an Azure Machine Learning compute cluster allows it to scale down completely when idle, reducing costs.

Answer

Configure Azure Automation runbooks to stop the physical datacenter servers

Answer

Set the minimum number of nodes equal to the maximum number of nodes

Answer

Use Azure Functions timer triggers to delete the compute target every evening

Question 11

You are architecting a resilient, high-throughput AI telemetry ingestion pipeline using Azure Event Hubs. The pipeline must support multiple independent downstream AI consumer applications reading the same telemetry stream at different speeds without interfering with one another. Which TWO architectural components or features must you configure? (Choose two)

Accepted Answer

Multiple Consumer Groups. To allow multiple independent consumer applications to read the same stream, you must use multiple Consumer Groups. Additionally, throughput is scaled using Throughput Units (or Processing Units in Kafka/Dedicated tiers).

Answer

Azure Service Bus Topics with subscriptions

Answer

Capture partitioning via Geo-Disaster Recovery

Answer

Event Grid system topics

Question 12

Your Azure OpenAI model deployment is experiencing a sudden latency spike. You want to determine if the bottleneck is due to server-side processing time or network transport overhead in your client application. Which Application Insights telemetry property should you inspect?

Accepted Answer

Dependency telemetry duration compared against custom client-side timers wrapping the API call. In Application Insights, the duration property of dependency telemetry records the total time taken for external calls, while server-side request telemetry records server processing time.

Answer
