Requirements
ContentAnalysisService
The company's data science group built ContentAnalysisService which accepts user generated content as a string and returns a probable value for inappropriate content. Any values over a specific threshold must be reviewed by an employee of Contoso, Ltd.
You must create an Azure Function named CheckUserContent to perform the content checks.
Costs
You must minimize costs for all Azure services.
Manual review
To review content, the user must authenticate to the website portion of the ContentAnalysisService using their Azure AD credentials. The website is built using React and all pages and API endpoints require authentication. In order to review content a user must be part of a ContentReviewer role. All completed reviews must include the reviewer's email address for auditing purposes.
High availability
All services must run in multiple regions. The failure of any service in a region must not impact overall application availability.
Monitoring
An alert must be raised if the ContentUploadService uses more than 80 percent of available CPU-cores.
Security
You have the following security requirements:
* Any web service accessible over the Internet must be protected from cross site scripting attacks.
* All websites and services must use SSL from a valid root certificate authority.
* Azure Storage access keys must only be stored in memory and must be available only to the service.
* All Internal services must only be accessible from Internal Virtual Networks (VNets)
* All parts of the system must support inbound and outbound traffic restrictions.
* All service calls must be authenticated by using Azure AD.
User agreements
When a user submits content, they must agree to a user agreement. The agreement allows employees of Contoso.Ltd to review content, store cookies on user devices and track user's IP addresses.
Information regarding agreements is used by multiple divisions within Contoso, Ltd.
User responses must not be lost and must be available to all parties regardless of individual service uptime. The volume of agreements is expected to be in the millions per hour.
Validation testing
When a new version of the ContentAnalysisService is available the previous seven days of content must be processed with the new version to verify that the new version does not significantly deviate from the old version.
Issues
Users of the ContentUploadService report that they occasionally see HTTP 502 responses on specific pages.

Explanation

Box 1: No
Front Door can dynamically compress content on the edge, resulting in a smaller and faster response to your clients. All files are eligible for compression. However, a file must be of a MIME type that is eligible for compression list.
Box 2: No
Sometimes you may wish to purge cached content from all edge nodes and force them all to retrieve new updated assets. This might be due to updates to your web application, or to quickly update assets that contain incorrect information.
Box 3: Yes
These profiles support the following compression encodings: Gzip (GNU zip), Brotli Reference:

Topic 7, VanArsdel. Ltd
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.
