Current environment
Requirements
The application components must meet the following requirements:
Corporate website
• Secure the website by using SSL
• Minimize costs tor data storage and hosting.
• Implement native GitHub workflows for continuous integration and continuous deployment (Cl/CO).
• 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.
Corporate website
The company provides a public website located at htlp://www. vanaisdelttd.com. The website consists of a React JavaScript user interface, HTML,CSS, image assets, and several APIs hosted in Azure functions.
Retail store locations
• Azure Functions must process data immediately when data is uploaded to Blob storage. Azure Functions must update Azure Cosmos D3 by using native SQL language queries.
• Audit store sale transaction information nightly to validate data, process sates 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.
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.
HOTSPOT

How should you configure the solution? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
Explanation:
Scenario: Retail store locations: Azure Functions must process data immediately when data is uploaded to Blob storage.
Box 1: HTTP
Binding configuration example: https://<storage_account_name>.blob.core.windows.net
Box 2: Input
Read blob storage data in a function: Input binding
Box 3: Blob storage
The Blob storage trigger starts a function when a new or updated blob is detected.
Azure Functions integrates with Azure Storage via triggers and bindings. Integrating with Blob storage allows you to build functions that react to changes in blob data as well as read and write values.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You are developing an Azure solution to collect point-of-sale (POS) device data from 2,000 stores located throughout the world. A single device can produce 2 megabytes (MB) of data every 24 hours. Each store location has one to five devices that send data.
You must store the device data in Azure Blob storage. Device data must be correlated based on a device identifier. Additional stores are expected to open in the future.
You need to implement a solution to receive the device data.
Solution: Provision an Azure Event Grid. Configure event filtering to evaluate the device identifier.
Does the solution meet the goal?
- A . Yes
- B . No
B
Explanation:
Instead use an Azure Service Bus, which is used order processing and financial transactions.
Note: An event is a lightweight notification of a condition or a state change. Event hubs is usually used reacting to status changes.
