Question 2

You need to store custom AI container images in a private registry hosted within Azure. Which Azure service provides a managed Docker registry service?

Accepted Answer

Azure Container Registry. Azure Container Registry (ACR) is the managed Docker registry service in Azure used for storing and managing container images.

Answer

Azure Blob Storage

Answer

Azure Managed Disks

Answer

Azure Artifacts

Question 3

You have an AI model container that takes 10 seconds to load weights into memory upon startup. Users report HTTP 503 errors immediately after deployment because traffic is routed to the container before it is ready. Which probe should you configure?

Accepted Answer

Startup probe. A startup probe in Kubernetes or Container Apps delays liveness and readiness checks until the application has fully initialized.

Answer

Liveness probe

Answer

Resource quota probe

Answer

TCP socket probe

Question 4

You are deploying a custom PyTorch model container image to Azure Container Apps. The container needs to scale out based on HTTP concurrent requests. Which built-in scale rule type should you configure in Azure Container Apps?

Accepted Answer

http. Azure Container Apps supports a built-in HTTP scale rule that scales applications based on the number of concurrent HTTP requests per replica.

Answer

azure-service-bus

Answer

cpu

Answer

tcp

Question 5

You have an AI model container hosted in Azure Container Registry. You want to ensure that every container image pushed to the registry is automatically scanned for known vulnerabilities before deployment. Which ACR feature should you enable?

Accepted Answer

Microsoft Defender for Cloud vulnerability scanning. Microsoft Defender for Cloud integrates with Azure Container Registry to provide vulnerability scanning for container images upon push or import.

Answer

ACR Tasks auto-purge

Answer

Content Trust

Answer

ACR geo-replication

Question 6

You are configuring GPU time-slicing on an AKS cluster to maximize GPU utilization for multiple lightweight AI inference containers sharing a single NVIDIA A100 GPU. Where must you define the time-slicing configuration profile?

Accepted Answer

A Kubernetes ConfigMap referenced by the NVIDIA device plugin daemonset. GPU time-slicing in AKS is configured using a ConfigMap that defines replica counts per GPU device, which is then applied to the cluster.

Answer

Inside the Dockerfile of each individual AI container

Answer

Via Azure Container Apps workload profiles configuration

Answer

In the Azure portal under AKS cluster node pool properties

Question 7

You have an AI scoring script that runs periodically. You want to execute this containerized workload on a schedule without managing virtual machines. Which Azure service is best suited for running containerized batch jobs on a schedule?

Accepted Answer

Azure Container Apps Jobs. Azure Container Apps Jobs allow you to run containerized batch tasks triggered on a schedule, on-demand, or via events.

Answer

Azure Kubernetes Service CronJobs

Answer

Azure Container Instances with restart policy Always

Answer

Azure Functions with HTTP triggers

Question 8

You need to deploy a containerized AI model to Azure Container Apps and configure it to scale based on Azure Service Bus queue messages. Which scaler should you specify?

Accepted Answer

azure-service-bus. Azure Container Apps supports KEDA scalers natively, including the azure-service-bus scaler.

Answer

azure-blob

Answer

memory

Answer

cron

Question 9

You are configuring TLS termination for an AI model API hosted in Azure Container Apps using a custom domain name. Where must you upload or configure the custom SSL certificate?

Accepted Answer

In the Container App custom domains settings using a Key Vault reference or uploaded certificate. Custom domain certificates in Azure Container Apps are managed via the custom domains and certificates blade of the Container App resource.

Answer

In the Azure Container Registry webhook configuration

Answer

Inside the container image filesystem under /etc/ssl/certs

Answer

On the underlying Azure Container Instances node pool

Question 10

You are scaling an AI workload in Azure Container Apps. Which TWO scale rule triggers are natively supported without custom KEDA extensions?

Accepted Answer

HTTP concurrent requests. Azure Container Apps natively supports scaling based on HTTP requests, CPU, memory, and Azure Service Bus without manual KEDA manifest configuration.

Answer

Azure Virtual Machine disk I/O throughput

Answer

Active directory login failure rate

Answer

Custom hardware temperature sensors
