NEW QUESTION 539
You deploy an Azure Container Apps app and disable ingress on the container app. Users report that they are unable to access the container app. You investigate and observe that the app has scaled to 0 instances. You need to resolve the issue with the container app.
Solution: Enable ingress, create an HTTP scale rule, and apply the rule to the container app.
Does the solution meet the goal?
A. Yes
B. No
Answer: B
Explanation:
Make sure you create a scale rule or set minReplicas to 1 or more if you don’t enable ingress. If ingress is disabled and you don’t define a minReplicas or a custom scale rule, then your container app will scale to zero and have no way of starting back up.

NEW QUESTION 543
You have a Linux container-based console application that uploads image files from customer sites all over the world. A back-end system that runs on Azure virtual machines processes the images by using the Azure Blobs API. You are not permitted to make changes to the application. Some customer sites only have phone-based internet connections. You need to configure the console application to access the images. What should you use?
A. Azure BlobFuse
B. Azure Disks
C. Azure Storage Network File System (NFS) 3.0 Support
D. Azure Files
Answer: A
Explanation:
Azure BlobFuse allows you to access Azure Blob Storage from Linux and Azure services as if it were a local file system, without changing the application. This is particularly useful for your scenario where you can’t modify the application and need to process images stored in Azure Blob Storage. BlobFuse provides the necessary interface between the application and Azure Blob Storage.

NEW QUESTION 544
You create an Azure Cosmos DB for NoSQL database. You plan to use the Azure Cosmos DB .NET SDK v3 API for NoSQL to upload the following files:
You receive the following error message when uploading the files:
“413 Entity too large”
You need to determine which files you can upload to the Azure Cosmos DB for NoSQL database. Which files can you upload?
A. File1, File2, File3, File4, and File5.
B. File1 and File2 only.
C. File1, File2, and File3 only.
D. File1, File2, File3, and File4 only.
E. File1 only.
Answer: B
Explanation:
Each file has a maximum size of 2 MB. So File 1, File 2 Only can be uploaded.

You develop a Python application for image rendering. The application uses GPU resources to optimize rendering processes. You have the following requirements:
– The application must be deployed to a Linux container.
– The container must be stopped when the image rendering is complete.
– The solution must minimize cost.
You need to deploy the application to Azure. Which environment configuration values should you use? (To answer, select the appropriate values in the answer area.)
Answer:
Explanation:
Box 1: Azure Container Instances. Kubernetes can manage ACIs but is not a ‘compute target’ and it will increment the cost. The container instances in the group can access one or more NVIDIA Tesla GPUs while running container workloads such as CUDA and deep learning applications.
https://learn.microsoft.com/en-us/azure/container-instances/container-instances-gpu
Box 2: Restart Policy. To stop the container after the execution (in fact is avoiding to restart it after a succeeded execution): set an appropriate restart policy for the container instance, depending on whether the command-line specifies a long-running task or a run-once task. For example, a restart policy of Never or OnFailure is recommended for a run-once task.

A company uses Azure Container Apps. A container app named App1 resides in a resource group named RG1. The company requires testing of updates to App1. You enable multiple revision modes on App1. You need to ensure traffic is routed to each revision of App1. How should you complete the code segment? (To answer, select the appropriate values in the answer area.)

NEW QUESTION 547
HotSpot
You develop a containerized application. The application must be deployed to an existing Azure Kubernetes Service (AKS) cluster from an Azure Container Registry (ACR) instance. You use the Azure command-line interface (Azure CLI) to deploy the application image to AKS. Images must be pulled from the registry. You must be able to view all registries within the current Azure subscription. Authentication must be managed by Microsoft Entra ID and removed when the registry is deleted. The solution must use the principle of least privilege. You need to configure authentication to the registry. Which authentication configuration should you use? (To answer, select the appropriate values in the answer area.)
Answer:
Explanation:
– Registry Authentication Method: A System-assigned Managed Identity. It’s tied to the AKS service and automatically managed by Azure, aligning with the requirement for authentication to be managed by Microsoft Entra ID and removed when the registry is deleted. It adheres to the principle of least privilege as it’s specific to the AKS resource.
– Registry Azure RBAC Role: The AcrPull role is the most fitting. It provides just enough permission to pull images from ACR, aligning with the principle of least privilege and meeting the requirement of the deployment process.

You are developing an Azure Function app. The Azure Function app must enable a WebHook to read an image from Azure Blob Storage and create a new Azure Cosmos DB document. You need to implement the Azure Function app. Which configuration should you use? (To answer, select the appropriate options in the answer area.)

NEW QUESTION 549
Drag and Drop
You are developing several microservices named serviceA, serviceB, and serviceC. You deploy the microservices to a new Azure Container Apps environment. You have the following requirements:
– The microservices must persist data to storage.
– serviceA must persist data only visible to the current container and the storage must be restricted to the amount of disk space available in the container.
– serviceB must persist data for the lifetime of the replica and allow multiple containers in the replica to mount the same storage location.
– serviceC must persist data beyond the lifetime of the replica while allowing multiple containers to access the storage and enable per object permissions.
You need to configure storage for each microservice. Which storage type should you use? (To answer, drag the appropriate storage types to the correct microservices. Each storage type may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)
Answer:
Explanation:
– serviceA: Container file system. The container file system is local to the container and is only visible to the current container. It is restricted to the amount of disk space available in the container.
– serviceB: Ephemeral Storage. Ephemeral Storage is temporary storage that persists for the lifetime of the replica. It allows multiple containers in the replica to mount the same storage location.
– serviceC: Azure Blob Storage. Azure Blob Storage is a highly scalable and durable object storage service that persists data beyond the lifetime of the replica. It allows multiple containers to access the storage and supports per-object permissions.
NEW QUESTION 550
Drag and Drop
You are developing a web service that will run on Azure virtual machines that use Azure Storage. You configure all virtual machines to use managed identities. You have the following requirements:
– Secret-based authentication mechanisms are not permitted for accessing an Azure Storage account.
– Must use only Azure Instance Metadata Service endpoints.
You need to write code to retrieve an access token to access Azure Storage. Which code segment should you use? (To answer, drag the appropriate code segments to the correct locations. Each code segment may be used once or not at all. You may need to drag the split bar between panes or scroll to view content.)
