Question #170
You are developing an inventory tracking solution. The solution includes an Azure Function app containing multiple functions triggered by Azure Cosmos DB. You plan to deploy the solution to multiple Azure regions.
The solution must meet the following requirements:
• Item results from Azure Cosmos DS must return the most recent committed version of an item.
• Items written to Azure Cosmos DB must provide ordering guarantees.
You need to configure the consistency level for the Azure Cosmos DB deployments.
Which consistency level should you use?

• Item results from Azure Cosmos DS must return the most recent committed version of an item.
• Items written to Azure Cosmos DB must provide ordering guarantees.
You need to configure the consistency level for the Azure Cosmos DB deployments.
Which consistency level should you use?
Correct Answer:
D
Strong consistency in Azure Cosmos DB guarantees that reads will always reflect the most recent write operation, fulfilling the requirement for returning the most recent committed version of an item. This level ensures linearizability which is crucial for scenarios where accuracy and recency of the data are critical. However, it's worth noting that if the deployment extends to multiple write regions, strong consistency might not be achievable due to the inherent limitations in distributed systems. Thus, another consistency level like bounded staleness could be a better fit in multi-write region scenarios.
Question #171
HOTSPOT
-
You are developing an application that runs in several customer Azure Kubernetes Service clusters. Within each cluster, a pod runs that collects performance data to be analyzed later. A large amount of data is collected so saving latency must be minimized.
The performance data must be stored so that pod restarts do not impact the stored data. Write latency should be minimized.
You need to configure blob storage.
How should you complete the YAML configuration? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Background
-
VanArsdel, Ltd. is a global office supply company. The company is based in Canada and has retail store locations across the world. The company is developing several cloud-based solutions to support their stores, distributors, suppliers, and delivery services.
Current environment
-
Corporate website
-
The company provides a public website located at http://www.vanarsdelltd.com. The website consists of a React JavaScript user interface, HTML, CSS, image assets, and several APIs hosted in Azure Functions.
Retail Store Locations
-
The company supports thousands of store locations globally. Store locations send data every hour to an Azure Blob storage account to support inventory, purchasing and delivery services. Each record includes a location identifier and sales transaction information.
Requirements
-
The application components must meet the following requirements:
Corporate website
-
• Secure the website by using SSL.
• Minimize costs for data storage and hosting.
• Implement native GitHub workflows for continuous integration and continuous deployment (CI/CD).
• Distribute the website content globally for local use.
• Implement monitoring by using Application Insights and availability web tests including SSL certificate validity and custom header value verification.
• The website must have 99.95 percent uptime.
Retail store locations
-
• Azure Functions must process data immediately when data is uploaded to Blob storage. Azure Functions must update Azure Cosmos DB by using native SQL language queries.
• Audit store sale transaction information nightly to validate data, process sales financials, and reconcile inventory.
Delivery services
-
• Store service telemetry data in Azure Cosmos DB by using an Azure Function. Data must include an item id, the delivery vehicle license plate, vehicle package capacity, and current vehicle location coordinates.
• Store delivery driver profile information in Azure Active Directory (Azure AD) by using an Azure Function called from the corporate website.
Inventory services
-
The company has contracted a third-party to develop an API for inventory processing that requires access to a specific blob within the retail store storage account for three months to
include read-only access to the data.
Security
-
• All Azure Functions must centralize management and distribution of configuration data for different environments and geographies, encrypted by using a company-provided RSA-HSM key.
• Authentication and authorization must use Azure AD and services must use managed identities where possible.
Issues
-
Retail Store Locations
-
• You must perform a point-in-time restoration of the retail store location data due to an unexpected and accidental deletion of data.
• Azure Cosmos DB queries from the Azure Function exhibit high Request Unit (RU) usage and contain multiple, complex queries that exhibit high point read latency for large items as the function app is scaling.

- DAdd a private certificate.
- ECreate and configure a managed identity.
Correct Answer:
A
A
GPT-4o - AnswerTo correctly configure user authentication and authorization in an Azure App Service using Azure AD, the first action is to add an identity provider. This step is pivotal as it involves specifying Azure AD as the authentication provider, which facilitates managing user identities and access controls directly linked to your organizational directory. Managed identities, often confused in this context, focus on resource-to-resource authentication, not user authentication. Your initial focus should be on setting up Azure AD for user access before adjusting other settings or integrating additional security measures like private certificates.

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?

Azure BlobFuse is indeed the ideal choice in this scenario, not Azure Storage NFS 3.0 support. BlobFuse enables Linux containers to access Azure Blob Storage as if it were part of the local file system. This is critical since the application itself cannot be modified, and BlobFuse offers a seamless integration without needing changes to existing applications, facilitating smooth file access even under limited internet connectivity conditions. This solution ensures the application remains unchanged while still accessing the required data efficiently.

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.
