Azure Front Door with regional endpoints.. Global load balancing using services like Azure Front Door or Traffic Manager allows for failover across regions.

Answer

A single large VM.

Answer

Azure Storage redundancy.

Answer

Local VNET peering.

Question 4

Your team needs to receive an email alert if the error rate for your AI endpoint exceeds 5% for more than 15 minutes. What should you create?

Accepted Answer

An Azure Monitor Alert rule with an Action Group.. Azure Monitor Alert rules allow you to trigger actions (like email notifications via action groups) based on metric thresholds.

Answer

An Azure Service Health notification.

Answer

A scheduled Azure Function that polls the API.

Answer

A Log Analytics query saved as a report.

Question 5

You are configuring an Azure AI Language service resource in the Azure portal. Which THREE settings or blades are available for managing the resource? (Choose three.)

Accepted Answer

Keys and Endpoint. In the Azure portal, resource management blades for Azure AI Language include Keys and Endpoint, Pricing tier, and Identity (managed identities). Diagnostic settings and Access control are also standard Azure resource blades.

Answer

Virtual machine size selector

Answer

Container registry integration blade

Question 6

You are managing costs for a multi-tenant Azure AI project. You need to attribute usage costs specifically to the 'Research' department. What is the most effective approach?

Accepted Answer

Implement Azure Policy to enforce mandatory tags on all new resources.. Tags are key-value pairs that help organize and track costs in Azure Cost Management.

Answer

Disable diagnostic logging for the research resources to reduce billing.

Answer

Create a separate resource group for each department.

Answer

Change the pricing tier of the resource to 'Free'.

Question 7

What is the purpose of a 'Resource Group' in the context of Azure AI solutions?

Accepted Answer

To act as a logical container for managing related resources.. Resource groups act as a logical container for related Azure resources, making it easier to manage the lifecycle, permissions, and billing of a solution.

Answer

To provide high availability for the service.

Answer

To enforce network firewall rules.

Answer

To store the model weights.

Question 8

You are configuring an Azure AI Language resource and want to ensure that it can be accessed securely from an Azure Virtual Network (VNet) without traversing the public internet. Which Azure networking feature should you configure?

Accepted Answer

Private endpoints. Private endpoints allow you to connect securely to your Azure AI Language resource from a virtual network using private IP addresses.

Answer

Azure Front Door

Answer

Azure Bastion

Answer

VPN Gateway

Question 9

You are processing health-related clinical notes using the Azure AI Language service. You need to extract medical concepts and link them to standardized medical vocabularies such as ICD-10-CM and SNOMED-CT. Which specific feature and endpoint task should you use?

Accepted Answer

Healthcare text analytics (Healthcare-specific NER and relation extraction). Healthcare text analytics is a specialized capability of the Azure AI Language service designed to extract and link medical entities to standard terminologies.

Answer

Named Entity Recognition (NER) with standard prebuilt-entity models

Answer

Key phrase extraction with medical domain parameters

Answer

Custom Named Entity Recognition with a trained ICD-10 dictionary

Question 10

You have an Azure AI Search service. You need to monitor the number of failed queries to identify potential indexing issues. Which tool should you use?

Accepted Answer

The 'Metrics' blade in the Azure portal for the Search service.. Azure Monitor metrics are the standard way to track service health and query performance.

Answer

The 'Activity Log' in the Subscription blade.

Answer

The 'Security Center' recommendation dashboard.

Answer

The 'Resource Health' blade.

Question 11

When setting up an Azure AI service, you choose the 'Standard' tier. What is the primary benefit of this compared to the 'Free' tier?

Accepted Answer

Higher rate limits and production-level SLAs.. Standard tiers provide higher capacity, production-level SLAs, and support for enterprise-grade features.

Answer

Lower latency for all requests.

Answer

Access to experimental AI models.

Answer

Automatic data encryption.

Question 12

Which THREE features are critical for managing the lifecycle of an AI model in a production environment?

Model registry for version control.. Versioning, monitoring, and automated deployment pipelines are essential for production AI lifecycle management.

Answer

Hardcoding all environment settings.

Answer

Manual file copying via FTP.

Question 13

You are implementing opinion mining as part of sentiment analysis in Azure AI Language. An incoming review states, 'The room was spacious, but the staff was rude.' What does opinion mining return for this sentence?

Accepted Answer

Aspect targets ('room', 'staff') along with their corresponding evaluations ('spacious', 'rude') and individual sentiments.. Opinion mining targets specific aspects (e.g., 'room', 'staff') and associates a separate sentiment and assessment (e.g., 'spacious' is positive, 'rude' is negative) for each aspect.

Answer

A binary classification indicating whether the review is spam or genuine.

Answer

A single neutral sentiment score for the entire document.

Answer

A translated version of the review in English.

Question 14
